Doog-

If your warranty is up, I hope you don't need a new light engine. It is a $1200 part. Was the glass from the lamp or something else? DO you have any pictures?

Mark-

Check your color drive numbers (S030,031,032). You might have throw one of them off. They should all be between 112-132.

If you have DVE and an upconverting DVD player you can use the white balance adjustment (pg. 28 of the service manual) to get rid of the greenish tint.

I noticed a broken lense/glass in that opening. I am hoping that this is part of the light engine. Could you verify this.

Doog,
Upload

The lamp itself has a flat glass face. There is also a lense (for a lack of a better word) that has I beleive a reddish coating right AFTER the lamp, but before the "turn" the light makes to go down the light tunnel to the light engine.

The piece I'm thinking about is right where the words "Lamp Unit" are in the picture.

Here is a link that may have some pictures. It's about doing the ND Filter mod to IMPROVE black levels. It has some pictures and info you may find useful. http://www.avsforum.com/avs-vb/showthread.php?s=86218f58ddb8e4ad522a86445c21f640&t=547602&page=1&ZZ=30&highlight=jvc+nd+filter+mod

NOTE: replace the TWO Z's in BOLD with TWO P's to make the above link work!
ZZ=30&highlight=jvc+nd+filter+mod

I think I remember someone else saying that "lense" that is located in the light tunnel on their set was broken as well. It may be in the above link.

I don't think the "tunnel" is "part" of the light engine per-se, and that lense if it is indeed broken is not too expensive. (No where NEAR the cost to the cost of the light engine.)

Got to ask, when you took the LAMP assm out, was the LAMP assm INTACT? If so the broken piece has got to be from that first lense talked about above.

PS: You might want to post DETAILED info in this thread also... http://forum.ecoustics.com/bbs/messages/2/176314.html

Please post in the FORMAT that is mentioned in this post.

Section 3: POST DETAILED INFO ON YOUR SET(s)...

BTW: Please also let us know how JVC treats you since your set is just barely out of warranty I beleive you had previously posted in that thread asking about Best Buy Extended warranties, you stating your set was only 15 months old:http://forum.ecoustics.com/cgi-bin/bbs/show.pl?tpc=2&post=538370#POST538370

Guys, The more people that post "details" about their sets as suggested below increases the chance that JVC will take care of customers that are "offically" out of the warranty period.

Light engines aren't "cheap" $1,500 -$1,700, and those lamps aren't cheap at $200 a pop.

WANA69,
The lense that you are suggesting, lamp unit area, seems to be what broke on my unit. The lense is 1.5"x2" with a rainbow tint. Hopefully this can be installed when the light engine is installed. Do you think I could do any damage to the set by running it without the lense. It appears that this lense helps keep heat in the channel for the fan ventilation of the bulb.

I've had my set 16 months and JVC said they won't honor a repair of the light engine because it is out of warranty. I have a Best Buy EW and I have just started the file claiming process. I am hoping the claim goes well and that the new light engine is an improved edition. It would also be nice if I knew why the lense beyond the bulb broke.

I was wondering if I could get a copy of the service manual as well. I've been following this thread for the past year and keep meaning to ask for it, but finally found the time.

Thanks much...

It sound like your JVC is about as old as mine. I had a light engine swap done about a year ago and it was a huge improvement. The black levels were much better

Just a heads up. The service menu code works on almost all JVCs.

Last week I picked up a JVC 17" widescreen LCD for the bedroom and I found out the service menu access is exactly the same. I was able to adjust the locked picture setting and tweak the set to my liking. I'm glad JVC uses the same software across the boards.

Mr. Lynch
When you had the new light engine installed did any one state why the light engine was bad. I have heard that dust and dirt can be an issue, and if so what is the prevention? I know you have handed out a billion service manuals and wanted to know if I could a billion and one. Thanks Doug

Doog-

My set had the older light engine that used foil shielding. It was more prone to light leakage than the updated aluminum plate shielding. I don't believe dust was an issue.

Robert-
You need a prgram called Powerstrip. You can google to find it. You will also want to create a 1200x666 resolution using it. The timings can be found by also googling for (1200x666 powerstrip)

CROOKED PICTURE?? My 56" JVC HDILA has a tilted or crooked picture. About 1/2" off from left to right. Annoying as hell. Is there a way to adjust this, or do I need to return the set? THANKS

There is no adjustment for it. You would have to open the sealed light engine and physically move the chip set.

If it bugs you that much, swap the set out. Just check it before you leave the store. I know I would.

I don't blame you. My parents bought an HD set right before X-mas and it had a green thumb print looking mark on the bottom middle of the screen. They swapped it for a new set and it has been all good since then.

By the way, I confirmed this week that not only does the service menu work on the new JVC Pro sets (HD-P61R1U and HD-P70R1U) but so does the HDMI reset procedure described above.

I had a customer with dead HDMI ports, and instructed him on how to get into the service menu and go through the procedure, and it worked just as advertised. Thanks to those who posted that sequence.

Hey Gang,
Long time lurker, first post.
Ive got a 52Z575 that I picked up last July. Finally getting around to tweaking it. Mr. Lynch, can you forward me the service manual everyone seems to want?

Just this last weekend I set up the HDMI off my DVI-D port (built in Nvidia board) from a new HTPC. I used the 1200x600 settings, but am overscanning so much I cant see the Start menu or the Quickstart bar. Has anyone ever posted the timings for this display (JVC 52Z575 specifically)?

Thanks for all your input on the board, guys. Its made setting these things up alot easier.

Not quite, my 52z575 has been not working since December 26, purchased it Oct 2004. Diagnosis, light engine. Waiting for Best Buy to repair it under EW. Told the light engine is not available at this time and is on back order, which means they don't order one until one is available because of the high residual money that JVC wants so that they will get the old one back. I was told the tech has to come up with $5300 to get his hands one then he gets reimbursed when he sends old one back. Sounds really high but I am still left with out a HD for superbowl and well beyond. Not many options left, kind words haven't worked then loud words then frustration which also didn't work. I am probably looking at a mimimum of 10 weeks of down time unless a miracle happens. I have also heard of $300 to $600 for labor to install the light engine. Bless any one who is reading these threads and then purchasing a JVC. I wish I could start over.

Mr Lynch:

My 61Z575 is going out of warranty in about 10 days and after hooking up my computer I have noticed about 6 "Smudges" Is this something worth getting fixed or will the next screen do the same thing?

Posted on Wednesday, February 01, 2006 - 11:09 pm:

I'm another long-time "lurker"...posted on the lamp thread about that failure earlier this month (52z585, bought in June '05).
Now, the dreaded "no red". Tech. came today and confirmed light engine problem. He says it's likely a firmware issue rather than a physical problem, and that code is so protected no Techs can fix. He says a week for the part (I hope doog is wrong!).
His shop has replaced about 15 here in Salem, OR. He knows from JVC Tech. classes that JVC is invested in fixing inherent problems like this. I can only hope that before the extended warranty runs out (4 more yrs.), they get these glitches figured out.

I'm pretty sure that the smudges are between the two sheets of plastic that make up the TV screen. On my unit they go away once the TV warms up.

Steve is correct. The smudges should disappear when the TV warms up. I notice smudge marks sometimes early in the morning when it is cold in the house.

Wesley-
Post your email address and I'll send a Service manual out.

Doog-

Sorry to hear about your problems. My local tech said JVC charges a $1500 core charge for the light engine, and it takes about 10 days to get them.

That is what it is. I had a window open and it was below 70 degrees in the room and the screen looked terrible. When the TV and the room warmed up the "smudges disappeared.

Finally got the HTPC working with no over scan.
Will try to post a few screen shots soon.
I wasnt able to find the correct setting in Powerstrip, but since I was using an nVidia diplay (DVI-D to HDMI) I was able to make adjustments through the video properties control panel.

Basic settings were;
Resolution 1152x664
HFP 112, HSW 40, HBP 344, 44.96 kHz
VHP 5, VSW 5, VBP 76, 59.943 Hz
Screen Refresh @ 75 Hz

Picture Quality looks great!

Wesley,

If you have any more info on which display type is in that HTPC I'm sure that would be helpful.

Under system properties, OR when the computer first boots up, does it identify the id of the built in nVidia display?

Barring that, who is the mfg and what is the model number of the HTPC?http://forum.ecoustics.com/cgi-bin/bbs/show.pl?tpc=2&post=594305#POST594305

PS: Thanks for posting the settings. Look forward to seeing those pictures and ANY other info you can think of.

Linksys 54G wireless card
Currently running sound directly to the TV, but plan to install an audio card that supports SPID to the Stereo Reciever.
Video is running out the DVI-D port to the HDMI on the JVC.

As for the nVidia control panel;
It Identifies the JVC as "HD52z575A"
in the nView Display settings, click on "Display Settings"
It should have a checkmark next to "Treat Digital Display as HDTV"
Under "Select TV Format" you should check "720p HDTV"
The under "HDTV Overscan Configuration", I selected "Underscan" and the video card made the proper adjustments for the screen width.

Minor typo in the post with the settings, VHP should read VFP (Verticle Front Porch)

here are a couple fotos, the digital camera isnt very good in low light, but can get the idea. The pc is on the bottom shelf, below the cable box.

Mr. Lynch, if you get a chance can you forward the service manual please?

Nice setup and good pics. I really need to finish building my HTPC. I've used my current PC with my TV, but since we use it a lot for business matters the living isn't a good spot for it.

If you provide your email I can send you the service manual.

DOOG,
I had my light engine replaced last friday, It had been out since Jan 1. I called directly and was told by a guy named Vince, who apparently works in the DILA dept whatever that is, That the engines were on back order but that 230 of them were already on their way to JVC to be distributed to those who need them. Furthermore, he said only a handful of them were spoken for. So it sounds like Best Buy is jerking your chain.I would call JVC directly and by pass BB until the JVC warranty runs out. God Luck! Hopefully this will be the last issue I have to deal with but I am still on lamp 1 so we'll see.

Update to my post from 2 weeks ago. Suspected light engine failure confirmed by repair tech on 2/1. Replacement part came in exactly a week, now waiting to Wed. for repair shop to replace.
So far have missed the major college bowl games (due to lamp failure), and now the Super Bowl, Olympics, and Pebble Beach tourney because of this.
I know it's whining, but these were part of the reasons for putting out the $$'s for this TV in the first place (just last June). This is one JVC fan that is getting a bitter taste from this experience.
Do you suppose they care?!
