Question about Mitsubishi WD-52525 52" Rear Projection HDTV
When I power up my 52725 everything appears normal. The fans start and the bulb turns on. The sound comes on then the picture comes on. After a few seconds the set shuts off and the red light is on constant. Prior to this situation the set would not come on. We would unplug and try it again. Most often it would start up and be OK. As a point of reference I swapped out the bulb, no change. I swapped out the power supply board, no change. I swapped out the entire main chassis, no change. I would have swapped out the lamp ballast but I don't have one. Is it possible my problem might be the ballast? Any other suggestions would be appreciated. Thanks for any help.
The problem might be the thermal sensor on the light engine. with all the work you have done on this i would suggest taking a look at the thermal sensor. these are known to go out.
