Is the light engine new or refurbed?
Hope I can get mine back to making non-yellow, whites again.
I (sorta ) remember back when this set was new, and had a drop dead, gorgeous picture output.
When you get your new bulb, you may need sunglasses, again!
Thanks

it was thru the bestbuy warranty, so whoever they used, the repairs were done by united radio

i'm not sure if the engine was new or refurb, didn't seem any obvious way to tell and the tech didn't have any kind of invoice for it to note its condition or cost, sorry

Well, good thing I was not holding my breath:

Once again we apologize for any inconvenience you are experiencing with our unit. Please understand that your TV carries 12 months service warranty both for parts and labor. This warranty is effective from the date of purchase. Unfortunately your unit is already out of warranty thus you will be responsible to repair the unit.

You can visit the http://www.discount-merchant.com/. This website sells the optical block in discounted price. Please note that this is not an authorized dealer by JVC.

We're sorry that we cannot be of further assistance. Should you require any additional information, please contact us at customerrelations@jvc.com.

Sincerely,
post #6483 of 6625
Thanks for the help! Unfortunately they don't list one for my unit (HD61FH97). Any other leeds are appreciated. I wonder the if the compatibilty of light engines dicriminates by display size?
post #6484 of 6625
Has anyone repaired their set using one of the $250 optical block units available from discount-merchant.com? If so, how did it work out for you. Are they repaired units or just removals from scrapped sets?
post #6485 of 6625
Anyone know how to easily remove the screen? And by screen, I mean the whole 'chassis' type deal... the whole thing comes off, leaving only the optical block.

The last time I had a tech come to replace the LE (about a year ago), he simply removed a few screws and lifted the entire panel away, he didn't even need to take the LE off the TV stand.

Now I'm kicking myself cause I forgot how he did it... and I really want to get in there and give the projection lens a good cleaning.

Hi,

I looked around a lot and am to frustrated to keep searching (and I have the flu so my patience is thin to begin). I just wnat to watch tv via my cable box.

What is the secret to doing this?

I can only seem to use the internal tuner, and it only gets about 10 channels.

I am connected via the 75 Ohm, and the pic is displayed via the TV input.

Thank you.
post #6487 of 6625
Oh, and how do I quickly go through the various inputs via the remote control?

Again, Thank you!
post #6488 of 6625
Does the cable box have any other types of output connections?
In the menus for tuner set up scan for channels I don't know what type of cable service you have so you will have to decide for your self the type of scan to use, if one proves incorrect(no display) try other options, with cable box on and tuned to a known broadcasting channel. when done you should be able to tune tv to channel 3 or 4 and receive a signal from cable box.
There is a button labeled D/A near the upper left of the remote to switch between the internal digital and analog tuners! You may want to try this first!

There is no way to "quickly" change inputs unless you have an aftermarket remote. Input button I believe is at top near left of remote, and you have to wait for each to activate before you can move to next.

Read this thread, there is alot of good info and answers to some of the questions you have asked ......and probably will need answered sometime.

Might think about it and try it soon. Somebody posted about using what looked like a hand swiffer to remove dust inside.....I might try that too.
This totally worked for me. I was able to remove the cover easily. (i dusted the outside beforehand so no extra dust went in) then I was able to dust the lens, mirror and surround areas. Brilliant. After four years the TV looks new. Next is just making sure my setting are correct and I will install a new bulb.

Thanks!

No, no way, no how, not remotely related.

Have you taken your light engine apart to see if it has the typical burned optics?
post #6492 of 6625
No. Still doing research. Thank you for your help!
Are burnt optics the cause for the yellow tinge in these sets also, like the older ones?
Have you ever had one of these LE's apart?
When I take it apart, I want to have the probable repair parts in hand.
Do you know of a source for a model # HD61FH97 LE or repair parts?

I recently removed the front panel from my HD61FH97 and carefully dusted the back of the screen, mirror and lens.

I put everything back together and all is well except...
Occasionally, usually 10 - 15 minutes after turning it on, the lamp goes off
and the blue power button and red status light start flashing quickly.
The sound is not affected, so I assume that everything is still working, except the lamp.
I unplug/re-plug the TV and the lamp comes back on and stays on for a whole movie.
This doesn't happen every time I watch a movie; maybe every third time.

Does anyone know what causes this behavior? Could I have done something while dusting the inside of the TV to cause it?
I was very careful not to disturb anything while dusting, and other than this, the TV works great and the picture looks perfect.

If it matters, I only watch movies on the JVC, so it's typically on for about 2 hours, then off for 4 or 5 days.

Thanks for your help!

Hrmm... I had a problem where the TV would require several attempts to turn on. You could hear it buzzing and trying to spark a connection, but it would fail and the lights would start blinking like you described. But I've never had a problem where the TV has been on, and then randomly shut down on me...

But for the hell of it, try removing your lamp and using compresses air or a duster inside that area. Once I tried that, I never had my problem again (a lot of dust for such a small area dissipated when I used compressed air).

Or, maybe while dusting, you knocked some dirt loose and it got into the LE or main board, or whatever... and it's now overheating.

For example... my desktop computer recently had a problem where it was shutting down randomly on me. So I took it outside and got all the dust out of there, specifically the dust on the CPU fan. Apparently, the computer was overheating because there was so much dust (probably thick enough to keep the fan from even working, as the computer had been stored in my garage for a year before I had started using it again). Maybe your TV is suffering a similar problem with overheating.
post #6496 of 6625
I would remove the lamp and make sure the interlock on the lamp cover is not malfunctioning.
Cleaning the lamp chamber, and re seating/checking the lamp electrical connection may be a good idea also. I recall reading about a problem with the electrical connections on a lamp with similar symptoms, it was either here or with a Sony RPTV.
Use a vacuum cleaner and a small paintbrush to clean the lamp chamber, its probably better to remove the dust than to displace elsewhere into the TV.

If all fails, and your lamp is old, it may just be time to replace it. I don't know if these lamps can become intermittent, they are an arc lamp. May want to research that, or someone may chime in who knows.

Anyone have a link to instructions, preferably with photos, for removing the front panel and doing the lens cleaning?

My 70" is 4 years old. I'm still on the original bulb, but I'm going to replace it shortly and figured I should give it a clean. no yellow blob issues (yet).

I'm not one to commonly take apart expensive AV equipment, so any help is appreciated. I've looked through this thread but perhaps missed the info.

thanks.
post #6498 of 6625
f/u....my 70" clearly doesn't have the side compartments and vents for removal and easy dusting as described by other. So it looks like i either have the option of removing the front screen, or it looks like the rear back panel can be removed by a series of screws.

Any advice as to which is easiest to inspect the lens & mirror and allow cleaning?

Looking at the SM, looks straighforward and typical. Many screws from back into screen frame, a few more hidden under the front lower panel covers. Leave the top center screw in until ready to remove. Only handle the frame/screen by the sides.

Dusting is rarely enough. On the main mirror, you will need a soft clean cotton cloth and a bit of distilled water. Wipe down and then dry with a dry part of the cloth quickly. Work a quarter of the mirror at a time. Careful you don't transfer any sticky tape residue. Avoid chemicals.

Ditto main lens.

You really can't see dust on the main mirror in daylight. You have to do it in the dark, using a flashlight at an acute angle to the mirror. In daylight it may look perfect, but at night it will look like hell.

The back of the plastic screen rarely needs attention, maybe only a vacuuming with a soft brush nozzle.

i have a jvc hd-70fh97 with a messed up screen and I am looking to buy a parts tv

email me if any of you want to unload your 70"

Only my opinion, but I have owned JVC's for many years and Customer Service has been less than stellar. Now that they are out of the TV manufacturing business, I would expect it to be even less.

While that was a great model - many, many, many of them (including the SONYs that used the same LCOS chip) have and are suffering from the yellowing degradation of the Light Engine. It almost seems as though its a matter of time with the majority of sets. Please don't kill the messenger, but this is what I have experienced.

I have moved on the Mitsubishi DLP sets, which are thinner and have a much better black level and color response. They are also all 3D ready (or capable - depending on if you get a 738 or 838 series).

A 73" can be had on Craigslist here in Atlanta for $599-999.

Just my opinion.
post #6502 of 6625
Daddy oh I hear you and know exactly what you are saying

thing is I already replaced the light engine twice and got a whole bunch of $$$ into the set already...I would like to get another year or two out of it by hopefully picking up a scrap set for parts cheap because all I really need is a screen...

the light engine in it now is new and should be good for a while but my screen melted a bit in the sun not long ago...

If I can find one in the next little while I will be doing what you say and cutting my loses and buying a new set
post #6503 of 6625
well, the bulb on my 56" FH97 went pop friday night, so i have a new unit being shipped to arrive on tuesday. anyone have a link to instructions for replacing the optical unit?

4.5 years for the bulb seems like a not unreasonable time frame to me.

update: found replacement instructions at back of TV manual.............duh!
post #6504 of 6625
bulb unit came via fedex today..............luckily, the installation is on the side (!) of the set, so i only had to turn it 30 degrees to gain access..........less than 5 minutes to replace the light unit and i have TV again..........not very pretty or calibrated, but a viewable picture

any recommendations on the amount of time to burn in the new bulb before calibrating?

i'm sure everyone has different ideas of how long to wait, but you shouldn't need much calibrating other than readjusting the white/black levels, maybe some minor tint adjustment but nothing else should really change from a bulb change

I used to wait about 100 hours for the 3 lamps I replaced. Seemed pretty stable after that.

post #6508 of 6625
well think my display might be messed up unless one of you fine folk on here can help me, i tried searching and couldn't find anything similar

circuit breaker tripped today while tv was on, so go back reset, wait a lil bit, turn everything back on, and now the bottom half of my screen does this weird intermittent like scrambled flash (rarely it does like 4/5 of the entire of the screen)on either hdmi input (ps3 or cisco cable box, direct hookups)
tried unplugging the cables and power cycling the display and sources, no dice, still same thing...

am i hosed?
the ext warranty just ended a couple months ago and got the light engine replaced just before it did but not the control boards...
post #6509 of 6625
just tried the leaving it completely unplugged for like 10 minutes (including the hdmi cables) and its still doing it....
i'm screwed aren't i....




its starts off doing it just occasionally then after awhile it goes to almost constantly
post #6510 of 6625
I own a JVC 56FN97. I bought it when it came out and the stock bulb is still going!! Its been more then a year since the timer timed out. But I'm noticing the last few weeks it stating to go dim and flicker.

Looking online at bulbs online and see OEM equivalents from a brand named Opto on Amazon. Are they truly equivalent? Anyone have experience with the OEM equivalents available now?

I've also heard the bulbs are produced locally here in WA state in Redmond. Anyone know somewhere locally in the Seattle area to buy bulbs?
