The TV picture loses its color(almost looks lke a partial black & white negative)freezes up and the TV won't shut off. I have to pull the plug to turn off the TV. Upon restart, evrything is fine for about an hour when the TV again gose into the same mode as previously described. Pulling the plug and restarting the TV restores the picture for a short period of time. The lamp is on.
The symptoms of picture freezing, tv won't turn off and b'w pix are all indications of a bad dmd board.
Sounds like color wheel BP96-00250A. Have installed by professional $350 ish
