We've had this WD-52725 TV for about 8 years and it still works fine, but the picture quality has deteriorated lately. We're seeing faint green lines (slightly off from horizontal, about an inch or so apart) that pulse on the screen in an alternating pattern every couple seconds. The picture is also not as "crisp" as it used to be (not sure how else to describe it). I've replaced the cables with no effect. Other than cleaning the air filter, no maintenance has ever been done on it. Any ideas what could be causing the problem?
Sounds like a possible issue with the Optical light engine itself.

Good Day;
Keep talking to the factory, it is their product. Best Buy won't replace unless it is deemed not repairable and/or terms of the contract. You purchased the extra warranty because you most have felt that the TV might break down. Well, it did, now use the contract to repair your TV.
Good Luck, big IRISH.

I believe the format, or FMT board is going bad. this is not a do it yourselfer type repair, unless you have extensive electronics background - I have one myself with the same problem. I am waiting to get a new FMT board for mine.

Good Day,
It sounds like the TV has a bad COLOR WHEEL Part # 938P137010. 99.9% sure this will solve your noise.
Good Luck, Big Irish.
