post #2371 of 2403
I have a HD-56FN97 that works fine for some time and other times I get red shadows or blue highlights. I have searched this forum and used Google to no end to find what could be the problem or a solution.

-I know it's not the lamp since it happen with the old lamp and the new lamp.
-It's not a convergence issue since I have checked the convergence in the service menu.
-There are no faults in the service menu.
-Happens with component and HDMI inputs and in all color settings

I basically need to know if this could be a light engine issue as after turning the TV on and off several times, it seems to reset it back to normal until the problem slowly creeps back in. Could dust build up or overheating be a cause to the problem since I removed the back panel to try and clean it out and after I did that the problem went away. Re-installed the back panel and a few hours later the problem came back. Any feedback or insight into this issue would be greatly appreciated, thanks guys.

(Bought the TV back in 2005 had no issues except for replacing the bulb after 3+ years).

Man...I thought all those TV's would be dead by now! I'm sorry that you didn't get the word about the class action against JVC for the HD D-ILA series! I had three of those monsters, and all three had premature light engine failures! The most common failure I had was a brownish streaking across the picture, which I was told by a JVC authorized service tech that it was caused by excessive heat within the light engine (in my opinion a design flaw) and JVC opted not to fix it, and then refunded my money. I then bought a SONY which is still going strong!

I would be really surprised if you can still get parts for those TV's!

Good luck!

Well that sucks wish I would have known, thanks for the info MoPro. Maybe I will have a tech take a look at it to make sure what the problem is exactly. Looks like some light engines are still available for this unit and at around $330 and not the $1200 they used to be.

Would I be better off just buying a $300 TV since it's being used in the man cave (garage) anyways or is there a way to improve cooling on the unit if I do get the part replaced?

A tech will do you no good, they don't take apart light engines, just swap them in and out. JVC doesn't sell parts for the internals of the light engines.

Look at these two threads if you want to understand the problem with the DiLA design:

Thanks for the info ChuckF. I was thinking of replacing the entire light engine not just a small piece in it that broke. MY only problem is if it will be worth the trouble since I've found many people complaining about replacing the light engine several times. If replacing it will give me another three years of the set I'm thinking it might be worth it. Does anyone have a ballpark figure of the percentage of light engines that fail?

Basically at this point just wondering if I should go with a new smaller set or replace the light engine and hope to salvage this one for a few more years.

Thanks for all the information I've been provided with.

100%...eventually! As I said... I believe it was a flawed design. Almost any new LCD flat panel will do at least as well if not better, and it won't sound like a wind tunnel when you turn it on... and finally you won't have to worry about replacing an expensive bulb!

I really wanted to like that machine when it was first introduced, but after three failed units and much aggravation from service calls... I believe I have paid my dues enough to express my opinion about that POS!

Sorry to sound so abrasive, but you asked...so here it is:

I've chalked-up my experience with the HD-ila to the price of early adoption and moved on, and so should you!

Where can you get the optical unit for $330?

Found two at discount merchant. Right here ->http://www.discount-merchant.com/JVC...-p/1189211.htm

Point taken MoPro I was just hoping to be able to salvage it. Maybe I'll move on to a projector or an LCD.

Anyone know the compatibility of this unit to the cop#'s that jvc uses?

You do realize that the item discribed at the website you provided has a color wheel? (which is indicative of a DLP rear projector!)

The JVC Dila design does not use a color wheel!!!

I would be very suspect about this offering and practice due dilligence researching this part thoroughly!

Good Luck!

Boy...it sure got quiet all of the sudden!

My 2005 61" JVC is still running great, on it's 3rd bulb....I've only opened it up once to clean the inside. Hopefully it will keep working a little longer.
post #2383 of 2403
Mine is now a dedicated Animal Crossings City Folk display for my daughter and the Wii.
I'd really like to take the LE apart and find the casusal part and try to replace it, but there are alot of roundtuits I have.

Anyone have any problems with their audio optic port stop working?
post #2385 of 2403
If anyone out there is still using this TV, has anyone had issues with the audio output RCA port? I recently bought a soundbar and I'm using the TV audio output port to the soundbar input. When I turn everything on, no sounds come out of the soundbar...if I go to the TV's menu settings, there's a setting to turn the TV's speaker on and off...if I turn it on and then back off, the soundbar starts working. Had anyone run into this issue, and more specifically, a resolution to the issue? For now, I've got my cable box directly attached to the sound bar...there are limited inputs though, so if I added more than my TV and game system there'd be an issue.
post #2386 of 2403
I was feeling pretty confident about the longevity of my unit until I came across this thread. Yikes! I didn't know about a class action lawsuit settlement, much less the service problems. Ignorance is bliss...but after reading posts here, I'm expecting my set to croak any day now. I didn't realize these behemoths had such a short lifespan.

In any case, I just replaced the original bulb, which was long overdue. I didn't even realize how dim the set was until I downloaded the AVS calibration disc and gave it a go. (The correct settings with the original bulb produced a picture too dim to watch). The set looks like new again. (I had it professionally calibrated back in 2006, but I suspect those settings have been erased). I came here to ask if there is a way to turn off the overscan, which is the first procedure addressed on the disc. The answer is probably buried in this thread somewhere, but I didn't find it addressed directly in a thread search.

Incidentally, for whatever it's worth, my new calibrated settings are as follows:

Theater Pro mode:
Color Temperature: Warm
Contrast: -3
Brightness: +3
Color: 0
Tint:+1
Sharpness:-15

The brightness setting was tricky, since the set won't display below black.

Same time frame here perezozo...the only issue I have is with the sound issue mentioned above. Other than that, it's been a solid TV for us.

Yeap, mine dead about a year ago. Is there any way to fix it?

My 3rd bulb just went. Anyone just buy just a bulb and put it in the housing themselves? Found a cheap bulb here http://*******/Z0j4AT but wondering if I should get the $38 on or the $68 one...

Please stay away from the $38 Chinese knockoff lamps. They will be nothing but trouble. They have a high out-of-box DOA rate which sticks you with return freight, and in the best of cases they only last a few months which is poor economics. Buy a Philips or Osram quality lamp. Here's a couple of reliable vendors that the rear projector list folks have had good results from: http://www.avsforum.com/t/584936/official-2005-sony-kdsr-50-60xbr1-sxrd-owners-thread/23850#post_22548077
post #2396 of 2403
Agreed, I bought a cheapo once, dimmed considerably ......in a short period of time. Get a Phillips bulb, w or w/o housing in my opinion. I have gotten a few from Discount-merchant.com a few years ago.Not sure if they still offer the GENUINE Phillips bulbs. Beware of "OEM Replacement" play on words. cool.gif

replaced lamp 10 days ago, back to "brand new" condition...this tv does not stop of amazing me...even after 7 1/2 years of use

post #2400 of 2403
Just got the notice that my lamp needs replacing (I replaced it once before). Two questions...first, how does the TV know it needs replacing (number of hours on the lamp, actual performance of the lamp, etc?). The picture looks great so I'm hesitant to replace it if it isn't about to fail. Second, is there a real difference between the $40 or $80 lamps on the web retailers versus the $200 lamp that JVC sell? Where is the best place to get a replacement lamp?
