Picture perfect for about 15 minutes after bulb replacement...

color wheel issues replace light engine

Need the model number of the set and also if any lights on the TV come on or blink when the picture goes out or not.

Replace the main pcb

Did you clean the small mirror. Dust will cover this mirror and give you a very hay picture. This is easy job and takes 15 minutes at the most. Someone posted detailed destructions on how to do this already if you look for it under WD52525 hazy picture.

have authorized servicer do a memory intialization this is ussually for a pinkish or reddish picture

If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit

wrong bulb or defective bulb

Done

The lamp is turned on by a high voltage ballast, very similar to the ones in your fluorsecent light fixtures. Your ballast is starting to fail. You should have your TV serviced by a JVC authorized service center because they have the training to deal with this issue. Waiting until it fails could very likely cause more servere damage especially if it fails shorted then the power supply will need to be replaced as well.

What is the price of that and what did they do.
