No problem. You might want to look in the PS forum. I found this thread http://www.avsforum.com/avs-vb/showthread.php?t=752327 that says, "JVC HD-61FN97-seems to work fine with everything except 480p via hdmi"

Maybe someone can help:

- when you turn it on the red and blue light starts flashing after 10 second
- and then it turns off
- the bulb is brand new
- if you turn on/off a few times it will start up
- I checked service menu and all was listed as OK
- and it doesn't do this everytime
- no other problems in 2.5 years

Any suggestions?

Thank you so much!

At least I have an idea before I get ripped off. Any idea what that repair will cost?

Mine did the same thing. The TV thought it was over-heating ( I think), so I cleaned out the whole area around the bulb with a can of compressed air, and it worked fine after that.

Thank you so much!

My repair cost me nothing because I took a 5 year warranty when I purchased the tv.

It happened to me...it is the ballast....do a search for my posts on this issue..

It was not the ballast. It was the non-JVC bulb.

Do not waste money on bulbs made by LTI (LTI lamps)!

Can you post the p/n's of the bad and good bulb that was used??

TX...its easy to see or be confused by similar looking part #'s. Most of the parts I see on the web, identified as JVC p/n are TS-CL11OUAA, maybe they are all the same p/n but with different mfgrs? but have added the AA at the end, which your "GOOD" version is not showing.

Here's the JVC link for that blub, http://www.jvcservice.com/store/ProductDetail.asp?part=TS-CL110UAA

After owning my 56G886 for almost 2 years now...I'm finally having my first major issue.

I've been through the bulb issue already (2 months after purchase, the bulb blew. Local shop just swapped us a new one for no charge)

Now it's something a bit more serious...

I have all my audio / video running through a Pioneer receiver...that will make sense in a bit.

I was watching football and doing some work on the computer. The game was just kind of background noise at that point until a big play comes up and you can hear the announcer shouting. I turn to see what's going on and there's no picture. Still had sound because that's playing through the receiver. I switch channels just to make sure it's no the cable. Still no picture but the sound changes as it should. I switch the channel back to the game...still no picture but the announcer is going off about the last play.

I check the TV and the blue light is still on. I cycle the power (push the power button). I notice that I don't hear the fan running like I normally would when I turn the TV off. Then I push the power button again to turn it back on and the blue light comes on for a few seconds then goes off. The red light starts to blink rapidly. I also notice that I hear no fans at this point like I normally do when I turn the TV on.

Check the manual. Internal circuit board problem...contact dealer. Now that's not a good sign. So I unplug the TV from the power and let it sit as per the instructions in the manual. A few hours later I plug it back in and try to turn it on...same result. No fans turning on, blue light comes on for a few seconds then goes out and the red light starts blinking rapidly.

Since I'm not hearing the fan I'm thinking it's a main power board or something. I've not seen a description of this problem in these threads. I've seen blue and red light blinking or the picture going dim because of the bulb.

So I've go a call to a local repair shop to come out and take a look...and readying myself for sticker shock as the TV is not under warranty.

Anyone else had an issue like this?

Thanks

Ya, I did. Havn't fixed it yet since I bought an LCD flat panel to replace it. Would be interested in what you find was wrong with it.

Keep in mind that a new 61" 1080p version can be had for less than $2,000. Not sure how much it's worth to put into it to repair. Certainly not $1,000. But probably your repair costs will be much less than that. Certainly want to hear what you find out.

Tech came to the house last night. Took some measurment with a VOM at the ballast connections in the bulb compartment and said the ballast is bad. He also said he'd "repair" the power board (or something like that).

Then he started to relay stories of how he's repaired a few of these same TVs for the same problem. Hmmm...nice MTBF on those parts.

He was pretty straight forward with his answers and I asked what he thought the life expectancy of this particular set was and he said, without hesitation, "5 years...maybe 6". Then I asked how many repairs he thought that it would need in that time and he just said to replace the bulbs.

Well, the repairs are going to be $800. Parts & labor & pickup / delivery. I've seen this same set (HD-56G886) brand new for anywhere from $1K to $1.5K depending on who's hoops you want to jump through to get it.

The tech did take the TV with him. I was amazed at how light the thing was when we carried it out. I've never had to move it.

I'll update again when I get the set back. Estimate was about a week.

On a side note, the tech was saying something about a "software upgrade" that will be done on the set while he has it in for the repair. Anyone heard of this?

Waskly1977:

Thank you for providing that information. I believe your conclusions are also quite valid. IMO, the ballast board is also a weak area in the JVC LCOS sets, and although it does not fail as frequently as the lamp itself, they tend to take out other component areas attached to it such as the power board when they go.
The ballast board (QAL0676-001) from JVC online was quoted at $230.59, so it is an expensive repair no matter how you look at it.
My solution was to purchase an LCD flat panel for now, and perhaps repair the JVC later when there are more broken units available for parts.

I do not believe that "built-in obsolescence" is limited to JVC, in fact I am willing to bet that most of the HDTV's manufactured now have a fairly limited life expectancy. This disposable product paradigm is why I will never buy another HDTV from a tier 1 vendor. It’s just not worth paying for the enhanced build quality one would typically associate with a name brand product when it is simply not there.
Pricing of tier 1 products is competing closely with tier 2 and even tier 3 products in many cases. Its pretty obvious that in order to do this the name brands have had to cut some pretty huge corners.

on my 52Z575, i notice on ABC HD, the ABC HD lettering they put on the screen in the lower right corner is cut off a little bit.

anyone else ever have this problem?

I replaced my original bulb with a generic LTI lamp a few months ago, and its already getting dark, and now i have this problem with ABC HD, and the skin tones look a little on the orange/yellow side as well.
the overall picture quality is just not bright, sharp or crisp anymore

is this possibly all caused by the lamp going? or do i have more than one issue going on here?

thanks!

Probably a dirty mirror, thats about what happens when mine gets crudded up. I just automatically know that when the lamp goes out I also need to clean the mirror since it always gets dirty by the time I run though the typical (albeit pathetic) lamp life. My situation likely differs from yours since the set is located near the kitchen and the cooking fumes plate onto the mirror at a near constant rate. Due to that I have to clean the mirror at least twice a year. If you smoke I imagine you will be cleaning it more often than that.

Not sure about the lettering, I would consider it a feature. I hate those stupid logos, and they are getting worse, like SciFI includes a nice add on top of theirs now in addition to the moving garbage they curse us with when the normal barrage of advertisements are over.
If the networks had their way, there would be nothing but adds and paid advertisement content on every show with around 5 minutes of the actual program included. We need to push for Ala Carte so that the viewer can vote against this crap with their wallet.

when you say you clean the mirror.. are you talking about the piece of glass that the lamp sits up against? or you have to take about the light engine to get to the actual mirrors to clean?
and what/how do you clean them?

i wish there was a tutorial out there for this with some screen shots maybe too

thanks!


EDIT: Well,it was the cheap LTI bulb.. i took it out and there was a big bulging blister in it.. just waiting to POP!

52g786 just got this tv from a buddy. He has blown 3 bulbs in 2 years. Which I read is a common problem. He put in a new bulb in about a month ago. And still had no picture, but has sound. He got pissed about it and went and got a new tv. So i offered to take this one. I put in a new bulb and hooked it up per the manual. I have a picture and sound but the piture has 1/4" or so green lines running up and down on it. And 4-5" left and right of the screen are solid gray/black. What could the problem be? I have it hooked up to dish network receiver.

I searched a ton of post. And did a self check. It shows TUN-NG9 and HD-NG9 and everything else ok. I don't have a HD receiver so that could explain the HD-NG9. But what could be the cause of the TUN-NG9?

My two year old 61Z866 unit has developed a pronounced uniform green tint (acutally more of a uniform green color - all whites appear green). After the unit warms up, and is cycled off and then on again (sometimes this requires several off-on cycles), the color problem will clear up, and the picture will appear bright and sharp with correct colors.

The unit receives a component signal from a Denon AVR receiver. I've tried changing the input from Input One to Input Two and have even tried a composit video signal with no effect. It has never been provided an HDMI signal. If verified that settings are all normal, and have unplugged the unit for four hours in order to reset any potential configuration issues.

The lamp was replaced 18 months ago and appears to be fine based on visual inspection. So, does anyone have an idea what might be causing this issue? It doesn't seem to correspond to the descriptions of the green splotch or HDMI green tint issues described elsewhere in this thread. Any suggestions or assistance would be much appreciated. Thanks.

I had the same problem on a Z series.
Possible a software reset would do the trick, but you can't do it at home. 18 months is close on the bulb, but that's easy to detect. The TV will begin to dim over 1-3 days before it goes black and the front light blinks.

Hello everyone. I'm having issues with my JVC that I can't seem to figure out. Here's hoping someone else has already been through and resolved this.:):confused:

My set is acting like it cannot hold an HD picture (or any picture for that matter). The picture always "jumped" when switching between HD and non-HD channels, but now it's doing it all the time. It can't seem to hold either a wide screen (HD) or a normal screen width(non HD) at all. Jumps between the two roughly every second or so, making it impossible to watch.
Any ideas? I've checked the format from the HD receiver and it matches with what the TV is set at.
Thanks in advance!:)

Thank you for the help thedeskE.

The bulb is good. I swapped in our ready spare and there was no change to the picture quality. Still the pervasive green color.

Quick follow-up: you mentioned reseting the software. Does that require the tech to take the TV to a service shop? Is it done using a PC or laptop? If so, is that something that an owner could do with the right software? And one final question, any other suggestions regarding troubleshooting I can do before the service tech gets here? I can already hear him saying that he'll have to replace the light engine so it would be helpful to rule out the really expensive components through some additional owner diagnostics. Thanks again!

My JVC TV has vertical green lines on it almost constantly. They used to come and go but have not disappeared for 4 months now. I have searched through the forums and have not found an answer to this problem so I am posting it here hoping that someone will have some knowledge about it. I have checked out the service menu and everything come up OK.

Any help would be appreciated. I have called support for JVC but they just refer me to local repair shop.

When i did my (lining of black velvet mod ) on the inside of my jvc hd70fh96 i found that my mirror was soooo dusty/dirty. I cleaned it a perfectly as i could. Took me like 10 min. , i made sure there was no streaks , and when i fired her up...... WOW , i felt like i had a new TV. And i didnt even do a bulb change. It was alittle brighter and sooo much sharper. I clean mine once every 2 months now.

Can you describe how one cleans the mirror? Is it difficult?
How big is it? What cleaners do you recommend? Windex?
Thanks.

I've had issues with my HD52G886 set for some time now. When the scene is dark, the background would get real dark for a few seconds, then change to the proper display. As the scene would pan around or switch from a bright scene to a dark scene, the background would always have problems displaying the background properly, and it drives me nuts. It occurs on all inputs, DVD (HDMI), DirectvHD, video games, etc. I finally had some time off this week and had a service tech come out to look at it. It was throwing 5 different errors, which he wasn't exactly sure on as he had to check with JVC. I called today to see if they found out what the problem is, and they're saying I need a new digital board. They say it's going to cost $500 to fix. :eek: Searching through this thread, I assume this may be about right, and I'm assuming that the digital board is actually the hdmi board?

screwedinlincoln,

I had the EXACT same problem with my 52" JVC. It is a light engine problem and my extended warranty covered it in which they had to replace the entire light engine to fix the problem. Hope you are covered.

Is anyone have a problem with the green blob/tint on the screen with that latest 1080p model JVCs??? I am having a problem with my 52" first generation set and replacing the light engine sometimes fixes it but is not a 100% reliable fix. I am thinking of getting a new 1080p set but I don't want to bother if the new sets exhibit the same problems.

Woops, wrong owner thread. Sorry guys.

Just done the HDMI reset and as I am one of those people who are wary of going into the service menu I was suprised how easy it was to do following the instructions from an earlier poster. The HDMI was disabled I believe when an authorised service agent replaced the light engine, you'd think JVC would have informed the agent about the HDMI sensor. My bulb finally blew after 18 months and was pleased by the response I got from ConsumerCare the authorised JVC warrantors, they refunded me the shipping as well as the bulb.

I have a JVC model HD-56G787. It was purchased in 8/06 and has approximately 2300 hours on it. I've been reading through this thread for quite a while today and I've yet to come up with a solid answer. I have these "smudges" or "blotches" that look like fingerprints on the screen. There has been more and more appearing and they're basically all over the screen and not limited to one section. I've cleaned it numerous times with non-ammonia window cleaner so I know it isn't dirty. Some folks in this thread describe something similar but there doesn't seem to be a conclusive answer. Can someone lead me in the right direction? Thanks in advance.

hrbib21, I have also had smudges that show up on a white background and have previously dusted the lens cover with a soft brush to some success, but what I have noticed that after getting a replacement bulb the screen is perfect which leads me to think that the problem may lay with the surface of the bulb rather than the lens cover or mirror, perhaps a more knowledgeable poster would know if this may be the problem and how to rectify it.

I have a JVC HD62G786 TV that is driving me nuts. At first I thought it was a bad DirectTV receiver, but I was just sent another and it's doing the same darned thing:mad:!
The picture is jumping between resolutions and blacking out in between each setting. I tried resetting the HDMI input from instructions on here (THANKS!), but no results. The service menu self test reveals the following:
TUN: NG9
HDMI: NG9
Sync M: NG9
S: NG
AI0: NG9

Everything else reads okay. Any ideas from the experts out there?:confused:
The TV was bought and manufactured in 2005.
Thanks in advance!

Am a violating some sort of protocol on this boart preventing a response?
Or could it be my problem is something no one has heard of before:confused:

So only HDMI is effected? Is there any HDMI switchign in between the source and display?

I have the same TV and DirecTV service (an HR20) and have not had any problems except during channel change. It would take several seconds to settle down with the TV changing resolutions to match the changing resolutions on channels. To make the channel change go faster I set the output everything at 720p so that the TV did not have to changs resolution.

I have recently been investigating calibrating my 61z575. Perusing through the service manual shows some settings that are termed "fixed" and initially set at 0. The manual is explicit in that these are not to be adjusted. Are these truly supposed to be 0, or are they adjustable? The reason I ask is most of mine are NOT at 0 but some other value. Wondering if I should set all back to 0 and go about calibrating the display according to the service manual instructions, or if these are values set at the factory. They are changeable, but I have not noticed any visible difference when changing some of the values.

I've searched but can't find a definite answer. At what point is the digital optical output active? Can it be used for HDMI sources that come IN to the tv?

I'm not even seeing a red light inside the port on the tv, wonder if it ever worked.

Thanks

HD-56G886

Ok ive spent three hours reading through the whole thread and have come to no avail. :( Could someone whho has a ps3 and uses JVC HD-52Z575 52" HD-ILA HDTV-ready tv please post the perfect settings? ive spent hours changing and configuring but i just dont think i have the ps3 games looking at their best. :( could someone please post the settings their using on their tv for their ps3?? :o thank you so much! :)

The settings on one TV may not be the best on another TV. Too many variables.

You might want to get HD Video Essentials and calibrate your set from the PS3. It's out in Blu-ray now.

I have loved my hd-70g886 for over 3 years but now that it seems JVC (or anyone?) will not be making the lcos sets, what is everyone thinking for their next set?

the whites on my z set look really yellow. :/ im using a z model... anyone got any tips?

I'm in the same boat. I like my 52 inch G series but I am starting to want something bigger and more modern i.e. dynamic contrast, multiple HDMI, etc. I'm hoping someone will import the latest generation of LED and laser DLPs here into Canada so I can get a look at them but realistically I guess I'll be waiting for the promised new series of larger LCD flat-panels supposed to be coming out of the new generation plants starting in 2010. I'm also paying a little more attention to plasma than I did in the past.

By the way, LCoS is still very much alive in front-projectors, but that technology doesn't work too well for me.

Chuck, I suspect your bulb may be about to go, if your settings haven't changed.

I love mine. And have a spare bulb. Might buy another 1 or 2 spare bulbs. But this TV will move to a secondary location somewhere. I don't like plasmas, but that might be my next bedroom TV. I really lust after the Samsung A650. But at those prices,.... Well, I'll wait.

My bulb just blew this week, now I see a greenish coloration in the upper right corner I hadn't noticed before.

Kinda looks like a speaker is too close to the screen but I have Polks and they didn't effect the tv before....

anybody have experience with this?
Had to use my spare bulb...who has the cheapest replacements?
Rob

nikknightt,

I have been having the same exact problem, since I changed my bulb, so far no body can give me an answer, however I have only posted on ecoustics. I cannot offer any help but you are not alone. Some suggested it was a light-engine problem, but I already had that and this is not the same at all.

the whites on my z set look really yellow. :/ im using a z model... anyone got any tips?


I have seen this on my z set for two different reasons
Contrast too high,
bulb bad

Ok thanks guys thanks for your replies. yes my whites look very yellow... also it has a red tint aswell i haven't changed any settings except for turning off color management, dynamic gamma, and smart picture... my blues look red almost pink. :'( i tried changing the rgb settings in the service menu and that did absolutely nothing. i got as a rent to own so its no telling how long someone else had it before me without getting the bulb changed... well guess its time to call jvc! or rentway.

OK, here's one. My 52G886 is almost 3 yr old. I love it. Had one bulb replacement when the set was 1 yr old and that's it. Recently I discovered something weird.

In the upper left hand corner of the screen there is a black line about 1/4" think. It is about 1" down from the top and 4" from the left. It makes a right triangle with the corner of the set being the 90 degree angle. It is there when the TV is on and disappears when the set turns off.

It looks to me like there is a gasket behind the screen that perhaps fell out of its slot and is now hanging behind the screen, blocking the light coming the lamp. To test this I jiggled the TV slightly at that corner and the line moved. Moving the TV anywhere else does not move the line.

Is there a gasket (about a 1/4" thick - or at least casts a 1/4" thick shadow) behind the screen that could, if it fell down slightly, block the projected image? If so, what can be done about it?

I'd suspect a hair or bit of cobweb on the lens cover. Have you pulled the vent access doors to look? You may need to have the set on to see it. When you have the doors off, be sure to blow out the filter holes.

I use a feather duster to clean the inside of my set - CAREFULLY.

Found some interesting info on this website.
http://forum.ecoustics.com/bbs/messages/2/452344.html

here's an excerpt from the message board

I as a servicer get many DLP / LCD Projection TV's in for service. 80% of the problem is the lamp. However, for every 1 time that a customer brings me a Samsung or Sony brand TV in for lamp replacement only... I get 4 to 5 JVC and Panasonic sets.. From my personal experience, it seems like the problem really isn't the TV manufacturer but the lack of R&D on the UHP manufacturing end. VERY RARELY have I seen MATSUSHITA lamps from JVC or SONY just "stop functioning" from extensive use or wear... They are almost ALL BLOWN! Blown meaning the filament being exploded or lamp imploding.

I fail to believe that the design of the TV causes the lamp to "blow" every time. Most likely the filament being manufactured by Philips is a superior filament that is more resistent to heat and wear.

Most of the newer high end TV's by Samsung, Sony, and now Hitachi (has switched to philips exclusively) use Philips brand lamps and to me it seems like the failure rate is much less.. i would go as far as saying 60% to 70% less.

I have now purchased the PHILIPS brand JVC lamps from Discount-Merchant.com to see if it get better results. So far so good. Just by the feel of the box and the Philips logo I feel more confident in the product.

Discount-Merchant.com has bare bulbs for about $130.
Anybody know how to load one into the enclosure?

Philips Lamp review:
http://www.takingstuffapart.com/articles/1621/1/The-Philips-solution-is-herePhilips-TS-CL100UAA-JVC-D-ILA-Lamps/Page1.html

"With over 2,200 hours clocked and counting, our Demo JVCs are processing Hi Def cartons mornings and nights. The picture is still as good as it was three months ago and most importantly, NO FAILED LAMPS!"

Interesting. I find the Philips brand compact fluorescents to fail much sooner than other brands. Even their incandescents seem to die faster. And I'm still on my original bulb in my JVC. Got a spare in a drawer, though.

I thought the whole LCoS RPTV thing would last longer. Tried to find one lately? I went looking for one in the 50" or so range. No gots.

...I thought the whole LCoS RPTV thing would last longer. ...

Both Sony and JVC are still selling a lot of LCoS front-projectors. But in RPTV, The key seems to be reliability. The 1080p LCoS chips sold by both Sony and JVC have had a fairly high failure rate, with blotches and other color issues. Probably not as bad as you would assume reading this forum, since complainers tend to be noisier than contented owners, and we've had a number of angry campaigners. But enough to give the nod to DLP.

In electronics in general, solid-state normally works best, which means that one would expect that LCoS would triumph over DLP, which relies on moving mirrors. The fact that this hasn't happened in RPTV is I think a testimony to the quality of Texas Instruments production processes. But in the bigger picture, solid state is winning out, with LCD flat-panels taking over the display market in general, at least so far.

Yes, so it seems. I expect plasma to go into another decline. OLED might make it. DLP might be the last RPTV technology to struggle on against the thin direct view technologies. The bright side, I suppose, is that the predicted bulb shortage and consequent high prices never materialized. I have one spare bulb on hand. Not sure if I'll buy another one- by the time it might be prudent, they might be out of production.

I found some leftover JVC DILAs in the 50"-56" range, but they weren't priced competitively. Had to pass. At those prices, I'd expect a 70" 1080p unit.

... I have one spare bulb on hand. Not sure if I'll buy another one- by the time it might be prudent, they might be out of production....

I can't see that happening. Lamps are made by a number of manufacturers in a vast variety. Look at the Osram website. There's millions of TVs out that need them, so there's big money to be made in supplying replacement lamps for many years. If not by the big names (Osram and Phillips), then by smaller makers selling over the Internet. Quality might be a question in such a case, tho.

Vacuum tubes for vintage radios are still available, indeed there's a thriving if modest industry for them, so I would certainly expect RPTV lamps to be available for a long time.

BTW, are a lot of the vacuum tubes still coming out of Russia?

I am still on my first bulb, 3 yrs now 52g786 (knocking wood) but have been watching this site in case I need a spare. http://www.discount-merchant.com/product-p/jvc-ts-cl110uaa-new.htm&Click=2 I still have 2 yrs left on my extended warranty. I also watch their stock level, sometimes its 100 and other times its 0.

BTW, are a lot of the vacuum tubes still coming out of Russia?

I think this type of manufacture is shifting to East Asia simply because of the number of firms and skilled workers. The point about any of this kind of opportunistic manufacture is a) proven design (meaning minimal R&D costs or risks of product failure) b) known market conditions and c) adequate sales volume to write off tooling costs. Mercury-vapor hot lamps certainly qualify on all these counts.

You're probably right. Hopefully political events won't cut off supplies in the future.

anyone still have one of these models? its been pretty quiet around here..

My 52Z575 is acting kinda weird.. i am noticing that the very bottom of the picture is getting cut off on some channels. its more noticeable on news and sports channels that have a ticker going.

Does anyone think there might be some settings in the service manual that may address this?

I am thinking it may also be a warping bulb perhaps also.

the whites on my z set look really yellow. :/ im using a z model... anyone got any tips?

Your not just seeing things they are indeed yellowish. Had the same thing happen to mine when the tech came out he said the optical block needed to be changed. They just replaced it thursday and now it looks like new.

Cascade issue or just bad timing...

About 3 weeks ago we upgraded to the new directv hddvr box. the next day our bulb blew - broken glass in lamp. 1st bulb failure time after about 4 years of owning the hd-61z786. no light warning it was aging. I figure it had about 2400 hours on it.

Replaced bulb - worked fine for a few weeks. Now we are loosing our digital input. Flashing green and tries to work, over and over. Sometimes it stabilizes for a day and then starts up again. Bummer.... we have regular inputs, just digital signal stabilization issue.

Any suggestions? Time to visit a shop? Could this be a bigger issue I should be aware of? Any feedback would be appreciated. Do love the DH!

thanks-
michael

Might check the sat box with another TV, to determine if it's the TV or the DVR.

I tried the box on another tv - works fine. I even tried my old sat box playing some tevo'd recordings through the HDMI input and it had the same green flashing. I am able to send a signal through the standard analog inputs without a problem, but want the HD. I guess I'll have to bring in a repair tech. Any suggestions for one in San Francisco?

My HD 61z575 optical engine died 2 weeks ago. $1300 part plus labor. Obviously I did not do this and bought a new Samsung DLP 67a750.

I tried JVC support to see if they would help me out with this issue. The TV is 4 years old but I dont think it should die so quickly. I went up 3 levels of support only to get denied.

Anybody have luck with this issue? It seems to be a fairly common issue with the optical engine dying. I've got a dead TV that will sit in my garage or get sold on craigslist for next to nothing. I'm taking one last shot at anyone that may have a solution.

Seems to be a common problem. I just get P.O.'d when a part cost $1300 for a TV, when in my case I paid $1900 4 years ago for the whole thing. I thought it stupid then when I paid $175 for a 5 year warranty but if my TV dies, I think I am covered :eek: not looking forward to that battle. My original bulb blew in the first 3 months, replacement is still working (knocking on wood). Set still has a bright clear picture.

Mine's fine, good as new. Original bulb, too. Rec'd April 05. I haven't heard of failures other than these recent posts. I daresay most are still in everyday use, and will be for years to come. I know that's not comforting to people who have had failures- but those failures still seem rather uncommon.

I just did a search on light engine and see failures dating back to 2006.

My company has installed allot of home theater systems over the last fifteen years. I've noticed that rear projection systems have the shortest lifespans, regardless of the manufacturer. Its the light engine that usually goes out. I've seen plasmas & thin LCDs loose power supplies. Engineers are designing these things to sell at a reasonable price point and hopefully survive long enough to be enjoyed until the newest and greatest evolution in technology is rolled out. I'm sorry to sound so jaded, just sharing my experience. I'm now recommending industrial units for those willing to spend more and get better components & warranties.

All that being said, our JVC unit that stays on about 10 hrs/day has only needed a new bulb.

the whites on my z set look really yellow. :/ im using a z model... anyone got any tips?

Your optical block is bad, just had mine replace about three weeks ago. Also have a 60" Mits and after the new optical block on the JVC (56") it looks as good as new.

Gee, another bad JVC optical block/engine. And they deny there is a widespread problem with this on this model?

Sorry, Im pissed as mine blew and I have a giant brick of a TV in my garage. I refuse to pay $1300 to replace it. My set is 4 years old. After 3 levels of support they still wont do anything. I understand its 4 years old but come on, this degree of failure should not happen so quickly.

I heard a "pop" and my 61z786 went black last night after two years. Luckily I purchased a extended warranty from Fry's when I bought it. The red and blue lights are blinking together with no sound. Does this happen when only the bulb dies?

Yep. I looked it up in the manual. When both blink together, bad bulb or it's not seated properly. Pg 99 & 92. If they blink alternately, it's overheat.

Here are the two places I know to get bulbs:
JVC (http://www.jvcservice.com/store/ProductDetail.asp?Part=TS-CL110UAA)
PartStore (http://www.partstore.com/PartSearch.aspx?PartNumber=TS-CL110UAA&x=34&y=18)

Let us know how this works out for you. I keep a spare on hand; glad I've never had to use it.

Thanks Navychop for the info.
I am glad it is not something more serious. The bulb costs more than my extended warranty and the warranty is supposed to cover bulbs. But if they come out and want to charge me more, it is good to have an alternative. Hopefully I can get it going before college football this weekend.

OK Ive had my 52" JVC DILA set for 3 years. Still using the original bulb and no problems. I am thinkng of upgrading to a Blu Ray disc player. Is any one using a blu ray player with this set? Since this set is not full 1080i I am wondering if I will see any significant improvement over my upscaling DVD player. Any comparisons or recomendations would be very help full.

Thanks

I see improvement on my 61" 720p with my PS3 as a Blu-ray player.

I do as well. In fact I see a pretty significant difference.

Very significant difference with 56" 720p.

My saga ended last week on my bulb issue. Frys bungled the beginning of the warranty claim. They had to "put my number in the computer so that it would pop up in the computer in CA". After a week of getting no information by calling several people in the service dept and leaving messages for the store manager with no one calling me back, I visited the store. I had a discussion with the service manager and asked her to get the store manager. I was calm but determined and he came over being very apologetic. Evidently there had been a discussion about my claim between him and the service manager previously. None of the regular service people wanted to handle me so I am not sure what was in the computer log on the claim. The store manager ended up giving me total credit for a nice Christmas present I was shopping for (I did not know electric toothbrushes were that expensive) and he sent someone to install it that night.
Interestingly I got a call from the company in CA that normally handles the bulbs for the warranty the next Monday to arrange delivery for "the bulb" that had already been installed. I suppose I should have told them to mail it anyway but instead I told them that it had been delivered and installed two days before so the closed the claim.
All in all it took eleven days to get the bulb but I felt like the store manager had gone beyond what I had expected and was a stand up kind of guy. In the beginning- poor handling of the claim but in the end I think he did his best to make amends. The tv looks good with the new bulb.

Let us hope we get many years out of our LCoS units. I was really hoping to buy a 70" JVC DiLA one day....... :(

If your time horizon is more than 2 years, new generations of large flat-panel LCDs, many LED-lit, may fit your needs perfectly. There's also Neopdp from Panasonic.

Yep. Love to get a cheap OLED in 60 plus inches, but I'm not sure I'll live that long, let alone the JVC.

I also have a 52" Samsung A650 LCD. I really like it, but there's something about it I can't quite put my finger on. I've dimmed it a bit, will have to calibrate it.

I'm not sure if all companies are like this but with Fry's you pretty much have to go to the top to get anything done and then they do the RIGHT thing. I bought a floor model Samsung from them this past week. I got a great deal but no box, paperwork or cables. I was told, "You get the TV and the remote for it and that's it." Considering this I went ahead and bought their 5 year warranty which was quite reasonable at $130. Anyway after messing with the remote for about a week and things not seeming right I looked the remote directions up on the net to find they gave me the wrong remote. I called in to complain and told them that on Samsung's web site the proper remote was only $30 (pretty amazing if you ask me). To make a long story short, I was told by a sales guy and customer service manager that a floor model means whatever they give me whether they told me the remote was just A remore or THE remote and basically to buy a universal remote. I FINALLY got to the top manager of the customer service and they credited my purchase for the $30 for a remote. The bad thing is that this was not about $30. I can spend in an hour on lunch with a friend. This was about the fact that the lower level employees were ready to lose a customer who spends thousands in their store for a mere $30. Not to mention that I believe I was right. It seems that it is becomming more and more common that you have to go through 3 levels of people who have NO CLUE as to what customer service is and threaten to completely take your business across the street before anyone cares. I guess it may be common practice because 90% of the people would have accepted poor service and moved on. I just find it concerning and the fact that you had your issue at Fry's prompted me to post. As with you, in the end I'm happy that they did the right thing but I think it is cruddy that I had to go through all that time and frustration to get what should have been done right away.

YEP! But sometimes it works out. A few years ago, I was at BB, trying to buy a new SD TV. Very crowded. Finally got some help, buy THIS one. After long warehouse search, etc, no more available. So, OK, I'll by THAT one. Long warehouse search, always compounded by sales critters going to help others and "dumping" me, no such animal. OK, how about THIS 36" JVC? Ok, I'll find out. Turned it over to another sales critter, went to supper. We're waiting, waiting, going nuts. Guy came back from supper, and said "You're still here?" in a good way. Turns out, selection #3 was not available either. OH, steam building. Good, just fed, sales critter said "wait here, I'll be right back." Soon, he came back, after talking with god, or manager, or brain and authority equipped figure, and said "Here- take this next upgraded model, which we actually HAVE, for the same price as the one (third one) we wanted." We did. Took home 36" JVC SD TV with PiP, which we have still to date never used. But it's a nice 36" SDTV, and will be with us for years yet. Long after the 27" Sony SDTV has been passed on.

Yep, I went thru a lot, but they "made me whole" in the end, even if I never used the upgraded features.

And so I bought a JVC DiLA, and wish I could buy another one.

Well, i guess my story is not the only one. I have the JVC Model HD-52G886, and up until about 4 months ago, was just fine. Bulb went out, I called my dealer (who sells JVC tvs), bought the JVC OEM bulb, just to make sure there were no problems if something was to go wrong, and then 3 months later, my picture starts to turn black in the middle. I call my dealer, to let him know the bulb was going bad, he said that he thinks its the light engine.

What the hell is the light engine?

Well, I had a technician look at the tv (which I'm not sure if he really did or not), but he says that the voltage from the power source going into the "ballast board" was only getting 90-95 volts. Coming from a 110-120 Volt source (My wall), that seems a little weird.

Is this normal? Is it supposed to be that low?

Well, needless to say, I had already ordered a new bulb (after being told that my bulb only had a 90 day warranty, but I still sent it to JVC to try), put the new bulb in and it still looks the same.

Well, I dont want to spend $800 - $1000 for a tv that I paid $2000 for. I would just save up and buy a NEW NON-JVC tv.

Can someone maybe help me out with this? I can replace the part, just need to know what to look for and how much it will cost me.

Thanks for the help.

From what I've seen light engine failures usually manifest themselves as color blobs, usually green. This does sound like it could be a ballast, which is far less expensive. It's certainly worth further discussions with the tech.

The light engine is the part that generates the picture. The key component is the LCoS chip. It constitutes the bulk of the cost of the TV.

My G-series is well into its 4th year and good as new at 14,000 hours. Yours may well be worth fixing.

Which tech would you be referring too? Someone in here, or goto another shop here where I live? I consulted one of the authorized JVC repair shops, and they said they would look at it for free, problem is, they are 30 miles from me. I dont have the time for that unfortunately. $75 is what it will take for them to come to my house, but I dont want to spend that to find out that it'll cost me $1000, ya know? I was hoping that someone had the same issue, so I could go that route. I know that no one can fix something that they dont have in front of them, but just hoping.

Thanks for the reply. Maybe someone else could post a similar problem with a solution.

Well, it finally happened.

Just after New Year's eve, my bulb blew. I was out of the room at the time. My wife says she heard a loud pop, the screen went black, and the lights started flashing. No dimming was noted prior to burnout. I could not turn the set off. When I tried, it seemed to pause and turn itself back on, even after I waited several minutes. I unplugged it.

My 61 incher was installed 4/15/05, so I got almost 4 years out of the bulb. But only 4,818 hours. IIRC, they're supposed to be good for 6,000 hours. Oh, well. I bought a spare lamp assembly to keep on hand in August of 07, so I was ready to go. I think I might just buy the inner bulb this time around, and replace it, keeping the housing from the blown bulb.

8 years out of this technology won't be bad, but I'd rather keep it longer. Maybe with another spare, I'll get 12 or more years. At some point, I'll move it to a secondary, less frequently used location, thereby extending it's life. Or sell it. I wanted to buy a 70" dila, but that's history. In any event, my wife has informed me she wants the next one to hang on the wall. Who knows what technology will be available in another 4 years? OLED?

I note that the FAQ that discussed the bulb life, and the user manual, have been removed from the JVC site. Not an encouraging sign.

I wonder how many of us are still using their dila HDTVs as their primary TV.

I am still hanging in there with my 52G786 as my primary TV. Still has a great picture. Funny, I was just on the other thread and looking up the instructions on how to confirm lamp operating time, since it has been a while since I last checked. Was going to do that tonight and see where I was. My set has been in operation since 7/14/05, the original bulb blew @ 100 hrs, 2nd one replaced by JVC is still in service. :D I have about 1.5 yrs left on my warranty. p.s. Do you have a source for just the inner bulb??? I have only seen the complete assy lately!

I am still using mine as my primary tv. (56") Mine is from early August 05'. My first bulb blew June 06', was not happy! :mad: My second bulb though, has done all I have asked of it. It's still going, 2 1/2 years of heavy use. The lamp timer (4500 hours, right?) was reset sometime around last summer, so it's probably getting close to 6,000 hours. I have one spare bulb, I hope I get at least 2 1/2 years total out of these 2 bulbs yet. It's depressing going into stores and see no RPTVs available, and you get 2 choices: reasonably priced 52" or lower sized flat panels, or 60" and larger flat panels that are way more expensive than most are willing to spend. I hope I can get a reasonably priced 56" or larger tv of WHATEVER type when my bulbs go.

p.s. Do you have a source for just the inner bulb??? I have only seen the complete assy lately!

Uh oh. I haven't looked yet. I thought it was mentioned earlier in this thread, and was going to search. Maybe I can look around this weekend.

If you find out anything, please post it here, as will I.

Some quick searching on the web found out that the bulb itself is not that much cheaper than the whole assembly. Best lamp price = $150, best assembly price $155. They were Phillips brand. (they) claimed that is what JVC is now using.

Yeah, $155 is the cheapest I have found the whole assembly too. My original bulb started getting really dark after about 1 year of service. I bought a new one (Phillips) from here (http://www.discount-merchant.com/product-p/jvc-ts-cl110uaa-new.htm&Click=2) and it has worked flawlessly for the past ~3 years. I think I gave a little more than $155 when I bought mine though.

Very significant difference with 56" 720p.

Just a quick question, what resolution are you (or anyone else for that matter :) ) sending to the display from the BlueRay player? 1080i or 720p? Thanks in advance!

1080

I send 720p from BD, HD-DVD, and my XBOX 360. That is the native resolution for my 61".

My tv often goes black with flashing lights. I think it's blue and red lights together. When it happens I turn off my TV, wait for the fan to stop (the lights stay flashing), and then I unplug it. When I plug it back in, it will turn on and work normally again until the next time.

Any ideas what it might be?

It sounds like your ballast is going. Mine went black with the flashing lights a total of three times before it wouldn't turn on again. Just got it fixed this week. $230 for the part and $200 for the labor.

Well, just as I expected. I had an authorized JVC Repair shop inspect the television for me, and of course my worst fears were realized. They called and informed me that my Light Engine was going bad. Great. Well, fortunately the other tech that looked at it for me, informed me of some news that might be helpful. (crossing fingers) He says that he worked on a Samsung (I believe it was that brand) who was having video problems, and he found out the the main chip inside it's light engine was loose. Not sure if it's built the same way, but he says that this chip was directly under the "glass housing" where the lamp shines through, and it must have gotten hot, cause the soldering had come loose. I can only hope that he can find something as easy as that for me, or else I will be posting a JVC Television on here for parts! $1263.13 was the qoute I got from the authorized repair shop, which I will NOT be paying, since I only paid $2000 for the t.v. As soon as I learn of what the issue is, I will post it.

Thank you for the update.

My Blu-Ray player is a PS3. If I remember correctly, there is a problem with outputting 720p from the PS3. I have mine set to 1080i.

Regardless of what player you have, I would recommend viewing both 720p and 1080i and pick the one that looks best to you.

I haven't heard of the 720p output issue. I use a PS3 for BD too. I am sending 720p and I haven't had any problems so far. <knock on wood>.

Same here.

I think you're thinking of some early games that were having some display problems, since been fixed.

There might have been an update to fix it.

It's been a while but when set to 720p over HDMI to a 720p front projector BD movies looked like 480i/p.

I'll have to check it out and see if I like 720p any better than 1080i.

Think my bulb is going, picture seems darker and tomorrow I'm having a SuperBowl party. Not sure if I'll be able to find a replacement on Sunday. How long typically before the bulb blows after first seeing darker? Anyone in N-NW Chicago burbs have a spare bulb they'd be willing to sell me?
thx, don

Well, it's too late now. Please let us know if it blew. I keep a spare on hand.

I replaced it before it blew. I was able to find a bulb at Fry's 30 miles away - they had 1 left. I do still have extended warranty left so I'm ordering a replacement now to keep as a backup.

Thanks for letting us know.

I have a brand new lamp bought from JVC, still in the shipping box for the JVC HD56G886.

If you are interested, PM me.

It says your not receiving PM's.

Hi,

I have an HD52G586. I use the TV speakers as my home theater center channel with the RCA input on the back of my TV from my A/V receiver.

I recently hooked up an upconverting DVD player to the HDMI port on the TV. The DVD player is also hooked up to my home theater receiver using digital coax, the same as my old DVD player was.

When watching the new DVD player I noticed that I was no longer getting the center channel sound from my TV. The rest of my home theater speakers work fine. I haven't changed any configuration or connections on my A/V receiver (other than hooking up the digital coax cable to the new DVD player) or the settings on the TV. I called my local JVC tech support but that went nowhere.

Anyone else have this problem? Has anyone gotten the center channel input to work when using the HDMI input on the TV?

I've turned it off on mine. You're much better off with a separate center speaker.

Monday I asked my wife to tell me if she noticed anything weird about the TV. I thought it had been getting noticeably dim over the last few days and much worse Monday evening. She couldn't tell. My second bulb blew on Tuesday. I replaced it with my spare and the thing is so incredibly bright right now it's amazing.

9/2005 Bought the set (HD56G786)
3/2006 Defective bulb went replaced with spare
Two weeks later: Replaced spare with warranty bulb
3/2009 Replaced bulb with spare

ok, its apparent that this so called electrician is not going to be able to fix my tv. are there any technicians out there that can help me? and by that, i mean, if i send you my light engine, can you rebuild it? or, is there a schematic somewhere that i can get of if so i can do the work myself (i work with electronics)? i just want my tv back! thanks for the help guys

Monday I asked my wife to tell me if she noticed anything weird about the TV. I thought it had been getting noticeably dim over the last few days and much worse Monday evening. She couldn't tell. My second bulb blew on Tuesday. I replaced it with my spare and the thing is so incredibly bright right now it's amazing.

9/2005 Bought the set (HD56G786)
3/2006 Defective bulb went replaced with spare
Two weeks later: Replaced spare with warranty bulb
3/2009 Replaced bulb with spare


Just a thought:

When replacing the lamp, the cooling system for the lamp should be cleaned of dust, etc so these contaminates are not deposited on the new lamp.


PS: On the lamp replacement dates- such info is more useful if you:
A: Post the part number of replacement lamp /any batch /lot/ manufacturer ID strings on the lamps /bulbs.....
B: Post how many hours of run-time you are getting on each lamp.
(Go into the user /service menu and get the lamp run time before doing a reset.)
C: Post your usage patterns: EG: Set once turned ON is left ON, Run for xyz hours per day..

(Stuff like that helps to show a pattern of bad lots, which manufacturer to stay clear of (given the choice) and helps in those cases of putting pressure on manufacturers to provide a replacement

Just curious, can you clean the "cooling system" without removing the back cover? Thought there was somthing?? that needed to be reset if the cover was removed?

I have removed my back cover several times in the last few years for cleaning and nothing ever needed to be reset.

By the way, this tv (HD70G886) still puts out a very pleasing picture for most content. Blacks are not so good, but for sports, hdtv and most movies it still performs well. I had a problem with how small the image got on scope movies with the black bars. But since I added a good projector for movies, I like this TV even more since watch the content that looks best on it and the rest on the projector.

Went back searching thru the threads, there was mention of the HDMI needing reset if the back cover was removed. I perfer component myself, could not see any difference with hdmi, hdmi produced a slight delay when switching between channels. So if I take off the back cover and it screws with the HDMI, I probably would not notice it. I assume the cooling area is nothing more than some plastic ducting and a fan?

Unfortunately, some of the most important data was lost. The bulb warning came on a few months ago. I finally got tired of it sometime in February, located the remote, and reset it. Approximately 1/1000th of a second after doing it, I realized that I didn't record the runtime of the current bulb.

What I was hoping to convey, without that crucial data, was that the second bulb lasted about 6 times longer, by the calendar not bulb time, than the original (known to be defective in these sets) bulb.

It's hard to quantify a usage pattern, but I can tell you that we use it now more than ever. Simply, we use it like a TV. I do tend to leave the set on if we are going to be away from the set for less than an hour. It's pretty rare that the set losses power and we try to wait at least 1/2 hour if before turning it back on once it's been turned off.

The first defective bulb lasted 1158 hours.

Here is the scoop

Model - 61Z786
Bought - November 2005
Usage - 2 to 3 hours daily as a primary TV
Bulb - Original

Tonight, I notice the picture appear to darken and within a few minutes
the screen goes blank and the red and blue LED's are flashing rapidly.

Cannot turn TV off via remote/tv switch. I turn off/on power and then
switch TV on. Same deal - dark screen and rapidly blinking LED's

I suspect it is the Lamp. Just want some confirmation, as someone mentioned
that a bad ballast could also be an issue at times.

I never got any lamp warning at all. Is that normal for a bulb failure ?

A quick yahoo search reveals

Philips replacement bulb with housing - $139
OSRAM replacement bulb with housing - $105 (on ebay)

Any recommendations/preference ?

Also, any reason to buy with or without housing ?

I did not get any warning on my bulb failure either. If you trust the seller on eBay, go ahead. It seems hard to find those bulbs elsewhere - out of stock/discontinued. I keep a bulb & housing assembly as a spare.

I tried to look up p/n TS-CL100UA on Ebay, no item found. Is this the P/n you used?? I know that earlier research found that the cost was $5 difference between replacement with a housing or one without.

Ok..My bad....as soon as I changed the p/n from "..A" to "..AA" at the end, I got all kind of hits from Ebay...:rolleyes:

So, is the consensus that osram and phillips are equivalent ?

Thanks for the link. So it looks like phillips is superior.

I will call discount-merchant.com tomorrow as the bare bulb
webpage is redirecting to the full enclosure.

BTW, i just pulled the old bulb housing out and the bulb inside is shattered
:(

Shouldn't there be a class action or something against this faulty design ??

I only got about 2000 hours on a bulb rated 6000 hours...

My first bulb I pulled out, even though it was still working but very dark picture had a lot of blisters on the bulb. I believe JVC more or less admitted that the original bulbs were not of good quality. The replacement bulb that JVC sent me has been in operation 3 + years (knocking on wood)

Ok, I need help. I am going to take this television apart and remove the Light Engine. Anyone know where I can get Schematics on the process of removing all the panels? I have pictures of some of the interanl parts look like (drawings), but is there an actual "manual" or "service guide" that can instruct me on what to do? I can do this all without it, but it would make it easier to figure out. Thanks for the help guys. This site is awesome!

Service Manual (http://209.187.238.153/movies/ServiceManual.pdf)

Service Manual (http://209.187.238.153/movies/ServiceManual.pdf)

Thanks.....I needed one of them:)

Thanks. I had some of the pics, just not the instructions. Thank you again and again!

Ok, I think I have found my problem!!!!! I have included some pics for anyone who can tell me what they are called, and if I can purchase them seperately. They are located in the light engine housing. I sure hope that one of you guys can help, cause this will save me about, I dont know, $1200!!!!!

First picture is what appears to be a filter that comes after the light but before the inside of the engine itself. It appears to be "burnt" which im pretty sure is not a good thing.

The second image is a another filter (i think) that sits in front of the first picture (it had what appeared to be a scratch on it, and when i went to check it with my finger, i accidentally wiped off a mirrored film, which im sure is important, so i need to replace that now)

The third picture is both of the pieces next to each other.

If anyone out there can get me an idea of a part # or something, I would be SOOOOOOOOOOOOOOO appreciative!

Thanks for all and anyones help in advance!

Well I picked up a new bulb and enclosure off ebay with the Osram map for $105. It works perfectly (night and day compared with the original JVC bulb that was giving bulb replacement errors). Only time will tell if this is going to be okay.

The seller had 22904 +ve feedbacks and the bulb is guaranteed for 180 days so that should give me enough time to work out if it's good or not.

While the bulb is apparently Osram, couldn't see anything on it that suggested the manufacturer

Well, JVC sucks! I have done everything in my power to try and get part numbers or exploded views or anything of the light engine, and yet bupkis! JVC can blow it out their anus'! Anyone in here looking for an HD-52G886 television that is in PERFECT SHAPE, with the exception of a LIGHT ENGINE? I will sell it cheap!

I am $30 away from fixing it, and can't get anyone to help at that crappy company! DO NOT BUY JVC ANYMORE!!! The t.v. looks great, but customer support blows chunks! Sorry for the ranting folks, just makes me mad! I also have 2 perfectly good bulbs for sell. Since I cannot use them, maybe they can bring someone else happiness! If anyone can help, I have posted the pics in an earlier post, so please let me know, before I throw this thing off the Skyway Bridge (200 feet in the air)!

I hate hearing stories like this. I've been in the HT business for about 15 yrs & I've commented many times on the issue of designed obsolescence, especially with the better equipment. Its become the standard of the industry, so don't think your experience will change with another brand.

Be patient, keep looking around on the internet before pitching it off a bridge. In San Antonio, I've found an independent, reasonably priced tech that has been successful repairing problematic TVs that the manufacture suggested being retired due to the cost of repairs being more than the value of the TV. Call around.

Thanks for the reply Soundgardner. The thing is, I HAVENT given up! I have done research after research and it seems that no one is willing to part with any information. I have found some filter and mirror sites that I have written letters too, hoping that they can point me in the right direction. My fingers are crossed!

If and when I do get this fixed, I can guarantee that I will NEVER purchase another JVC product. Aggrevation is not the word I would use for this insanity!

P.S. Soundgardner, what is the name and phone number of the shop that you contacted about your television? Maybe I can contact him and he can help me as well.

Thank you for all of your help in here. If anyone can offer other info., dont be shy! lol

Has JVC ever updated the firmware on this model?

My inlaws have one and the HDMI is routinly buggy, so I need to reset it in the sevice menu. I do not use the HDMI anymore becouse of it. Now, I wish to give them a blu-ray player and it would be nice to use it.

My HDMI has been out for over a year... I'd love to be able to find a new board!

Does the reset work?

never has

No worries, I do not think you are missing much anyway?

The board always goes out and needs service menu reset on DVD, HDDVD, DSS connection.

I dont think its worth the cash to replace.

i've done fine without it this long but I do want to upgrade to blueray and it would be nice to get that resolution

Mine is still going strong. I feed everything thru an Onkyo 805 into the HDMI input.

I hope it lasts until 61" OLEDs become affordable.

Red panel on my HD-52Z575 appears to have died, picture has blue tint. For awhile cycling power fixed the problem, now it appears to be stuck (off). I assume the fix is replacing the light engine, which I assume would cost more than a new TV. Pulled the electronics out the back of the TV and wiggled/thumped things a bit, that is the extent of my troubleshooting so far. Service menu reports "RG9" RGB error code, and when I go to convergence screen the red block is missing (and no red would explain blue tint, I think).

I will put the TV out with the garbage this week unless someone here tells me there is a repair that makes sense! Thanks!

Add me to the list of people who will never buy JVC again.

After 3 yrs light engine has failed. The "green blob" found on Sony LCOS models has turned up on mine now. As far as I can tell JVC is not doing anything like Sony's unofficial recall for the problem with this technology. JVC has been no help. I will never buy another JVC and will suggest the same for others.

Mine was purchased in the summer of '06. $2000 for 3 years is unacceptable. A big-screen TV should not be considered disposable.

MY HD-61Z786 has a dark area on the left side of the screen and overall is darker than it used to be. I thought maybe it needed a good cleaning as discussed here. Then I ran the "self check" from the service menu and got the following report:

LOB OK FAN OK
SYNC M: NG S: NG HD: OK
TIM OK
MAM OK DIG OK
MEM OK AVSW NG1
YC OK AIO OK
TUN NG2 GCR OK
IP NG1 RGB OK
DVI OK HDMI NG9

Page 2
FAN OK ALM OK
TMP OK
ATP OK ASH OK

PNL OK MEM OK
TMP OK AIO NG1
CARD OK

What do you think? With all of those "NG" is it toast?

Ended up calling JVC, they told me there was a software fix for this. Had technician come and he had computer problems, but he made a call and was able to restore the red panel from the convergence screen in the service menu! Just pressed sleep button while in red convergence screen!

If only there was a similar fix for my 70" JVC that has the dreaded yellow blob problem ...

I got mine long ago from (Jack Andolini, ManualsParadise.com), they will sell you the tech manuals and schematices, I paid $20, hope this helps. If you need anthing else.. send me an pm.

I just stumbled onto a 56GC87 that seems to mostly be working nicely, at the price of a bit over $100 bucks I couldn't pass it up. doing some research it seems my HDMI input problem is commonplace (neither HDMI port works). Also from reading around it seems I can potentially fix it with a firmware (or software) update by loading the update onto an SD card and putting it in the service port. then accessing the digital setup menu-software.

Does anyone have or know where JVC's obsolete software updates are? I've tried their site (nothing) and have an Email out to them but I don't expect they have them any more or allow downloading them.

BTW I do know about the Jumper reset thing, I'm just not convinced it's a permanent fix judging by the amount of people who do it and then report back that the ports stop working again as soon as you change inputs.

Friend gave me his HD-52G456 because of a yellow/green hue on the whole screen.

When accessing the RGB settings in the Service Menu, the B doesnt change at all. Am I to assume the Blue is shot and it a gigantic paperweight?

He said he had a guy out once and said the part that needs replaced is 800 bucks. Any idea what part that may be?

Probably. This is an early production D-ILA with many outdated features. I have a similar one and I'm happy with it for the moment but I wouldn't spend any money to fix it. For the cost of a new light engine ($1500+ with labor) you can buy a brand new 52 inch flat-panel (last year's models) with far better image processing, connectivity and a full warrentee, and no lamp replacement issues.

I second davegow's advice.
I have one as well and happy with it, but...

That's not what I wanted to hear. I got it for free and all but the wife wasnt too pleased I came home with a ginormous green colored HDTV....

Well, I have decided to sell my television. It doesn't seem that I'm going to fix it, considering that I can buy a brand new one for the same price! THAT SUCKS! Oh well, lesson learned. I have a JVC Model # 52G886HD. The light engine is not bad, but it also doesn't produce a good picture. You can see my earlier post with the pictures to understand. Everything in the cabinet is in perfect condition. Anyone looking for a 52" JVC Rear Projection in PERFECT condition, please contact me and make an offer. I'm sure I'll let it go REAL CHEAP!

I have an issue with my HD-52G786. Unfortunately for me the problem is moving from intermittant to constant. Each time I turn on the TV I get about 5-10 minutes in and blinking lamp/power lights. I haven't replaced the bulb since 06 when I had the ballast replaced, so I thought that a new bulb might be in order. I have an extra from back in 06 when the tech repair guy told me that my problem was probably a faulty bulb. So I bought a new one and still had a problem. THEN he told me since it wasn't the bulb I needed to replace the ballast. So I pop in this new bulb and still get the same thing. It happened once or twice a couple of months ago then was fine until a week ago. That is when I replaced the bulb. Now it is happening every time. I wait for the bulb to cool down, unplug and turn it back on. Now I have to do this two or three times before it stays on for good. Once it stays on it is good to go until turned off again.

The repair place tells me that replacing the ballast will be around $400 perhaps $500. The part is supposedly $125 (from him), so I know I am mostly paying for labor and a markup on the part. I can't imagine it is terribly difficult to replace. Is there a good place to buy parts from, or is JVC my only option? Also, what are the chances of the ballast actually being the problem? HDMI port is out- again; if that makes any difference.

Hey bfrd... If you get this note. I have a 52G 886 (SIlver) and Everything in it works great except the Light Engine. Wanna buy mine? Ill sell it cheap. Plus I have 2 bulbs that have low hours. One has maybe 2 hours, and the other probably has about 100 to 150. Offer me something and who knows. Also, where do you live. Im in Florida. Shipping will be involved. Let me know. My name is Mike

Well after four + years my lamp is going on my HD56G886. I received a message on screen the lamp needs to be replaced, to call for service, then to reset the timer. I had the original go out a couple of months after I bought this set (covered by JVC warranty at the time) but never saw any message on the screen like this time. Anyway.....Looking a bit on the Net I see there is a JVC boxed lamp for a bit over 200. and a Phillips lamp for about 130.. Any difference on these two besides the label?

The on-screen message is based on a running counter of time powered on. It is quite possible to get the lamp replacement message but still have a perfectly functional and good bulb.

That's what happened with mine after the first replacement. It started prompting me to replace it, so I just cleared the message and enjoyed the picture. When the bulb really goes you'll know it! :)

Thanks for the input. I figured that is what prompted the message and is what the message was based upon (used hours);). Still curious about the different lamps tho. Any thoughts?

I'd buy a new lamp when I see the message, if I didn't have one already.

Personally, I chose to buy the JVC, both for myself and my boss. I've had problems with other Philips bulbs, and just don't trust the brand name any more.

Thanks! That is the type of input I was looking for. And I agree about buying the bulb now.

Hmmm, now I am a bit confused. Is there a difference between the Philips, Orsam, and JVC lamps? From what I have read it sounds like JVC is using Philips now and if that is the case I don't see the difference between buying a JVC marked lamp and a new Phillips lamp. Am I missing something or just being a bit to anal?

DK. But I'd avoid Philips- under any rebranding.

Thanks
