Jvc hd-52g787

[qanda]This thread is about the JVC HD-52G787. Click here to see full specs[/qanda]I bought this tv in Sept.,2007 new. What a great picture it had.

After about 10-11 months, we noticed that the picture seemed to be getting darker, like the crisp bright picture was not what it was. It was almost daily that it was getting noticeably darker.

So I bought a new lamp and replaced it.

I reset the picture to factory setting with the onscreen menu.

This still didnt look right. A good picture but the brightness still was not right. After a couple of weeks, it started to get darker again.

The lamp was under warrantee, I sent it back and was sent a new replacement, but still it just doesnt look right.

It is watchable, but during the day it is very hard to see, especially darker pics.

My wife and I are smokers so I do have an ionic air cleaner to help to keep the air cleaner, but could smoking be causing something?

I looked inside through the left side and it really looks good. I dont see anything dirty. There is what appears to be another bulb of somekind in the center, near the bottom of the cabinet.

Could that be dirty and need cleaning?

I just dont know.

I have not gotten anywhere with jvc.

Any help?


Possible light engine problem.


Thats the one thing that I hoped was not the problem.

Looks like I just live with it as is until it just goes out.

Oh well, life goes on.

Thanks platinumsword for your reply.
