Hi all, I've been searching around and I've found a little information about this problem. I was given this 52" JVC D-ILA tv because it has a slight yellow / green tint to the entire screen through the D-Sub and RCA/S-Vid ports.

I've ordered a DVI-HDMI cable to try higher resolutions but I have the feeling I'm going to be stuck with this greenish tint.

The screen is not too dim (sorry no pics atm) so I don't think I need to replace the bulb.

Does anyone know how to enter the Service Menu, maybe I'll be able to change color settings in there?

What kind of hardware would this problem be if it's not a software setting?

I'm having a hard time finding anything other than replacement lamps as this tv is now well over 3 years old. I'm starting to think this isn't even worth my time

I don't know how to help other then to point you to another thread with a lot of info on that TV(http://www.avsforum.com/avs-vb/showthread.php?t=715594) which has some well documented issues. I have one my self the hd-56fh97 that has the dreaded yellow blob I think there should be some type of class action lawsuit, but I guess that's just wishful thinking . Anyway hope that helps.

I'd rather give you $10 than 10 minutes. I can always earn $10, where do I go to earn 10 minutes.

Nice gift.

How about the other inputs? RF, component, HDMI?
What does a mono image (B&W) look like? Turn the chroma (color) down all the way and report back on how 'grey' the screen looks.

The D-ILA's were nice sets, at least the potential was there. Too bad they had problems with CA (chromatic aberrations), a lack of inputs, inability to use a PC so the screen gets filled properly (without a hassle if it worked at all) and a terrible menu system (which was never corrected by JVC).

I've tried only VGA/RCA as of now, my dvi->hdmi cable showed up the day before I was leaving so I haven't had time to try. Will try when i return and get back to you with answers your questions. I'm guessing this isn't a bulb issue but something else hardware related, if it is do you know what it could be?

Also, i'm not a videophile type of guy, i love movies and building electronic components, but this is all new to me so thanks for the help.

here are some shots i just took, i think this sums it up... dim and yellow... turned tint all the way down to -30, rest of the settings are at 0. New bulb or something more serious?

THANKS!

it's not quite that washed out IRL but i think these pics show the issue enough. It's not terrible when you're playing full screen video with colorful scenes, though it could be brighter, but when that white screen shows up the yellow/green tint is definitely noticeable.

Grey scale is the first place I would go.
What is it like with the chroma (color) turned all the way down? That is step one. If it doesn't look absolutely gray (not bluish like most sets) or any other color, it's not correct.

It's not a phase (tint) issue.

Take a look here;

You are now the proud owner of a very heavy boat anchor. The light engine is bad which is typically a $2000 repair (I know because I am waiting for parts so Sears can replace my light engine...luckily I have a Master Protection Agreement on my 70" JVC). Unload it and get a new LED/LCD TV that doesn't get dusty, doesn't get dim and dingy over time, and doesn't turn to total crap because of sub-par engineering...JVC should be sued in a class action.

Great! Good to know, at least I paid nothing for it. After browsing menace2society's link I realized that it is the light engine and that i am screwed. Glad to hear you're going to be OK whenever you get a new light engine. What a joke. Thanks for your help

Before you "trash it", have you tried to gray scale the set??

No I have not, it's still setup attached to the computer, I will try today after work! I'm just skeptical because of the yellow line down the right side. Also is that something I need to set the service menu (how do i get into the service menu)??

Thanks

I didn't notice the "bar" towards the right side.
The "flickering" is another issue.
Service Menu access etc. are in those links I provided. Have you looked thru those yet?

It does appear it needs a light engine change out.
