Question about Mitsubishi WD-52725 52". Rear Projection HDTV

1 Answer

My mitsubishi 52725 shuts itself off after acouple hrs

Th tv will shut itself off anywhere from 5minutes to 6 hrs of great operation then the blinking green light appears. I have to unplug wait then plug it back in wait 60seconds till it stops blinking green and then the process will be repeated in a short time and is very annoying and frustrating. I have replaced the 12 bad caqps and installed a dpdt switch made the picture cleaner but still shuts down im about to throw this thing out the bed of my pickup going 80 down the freeway, would be cool:) to see

Its most likely the thermal fuse which is causing the problem. It gets up to operating temp then shuts down.

Posted a short while ago but have more information Mitsubishi DLP WD 52725 - sound no picture - blinks 3 short times and 1 long time


have you checked the lamp? with those models they will power up and if the lamp is bad you can hear audio until the tv shuts off. the lamp is located in the front behind the speaker grill assembly. if the "status" light is blinking then you are having a fan failure if the "lamp" light is on then check the lamp like i listed above.

does it give you the "airflow" message?
if so it needs a new thermal sensor by the lamp, known issue defective sensor..

resolder the horizontal driver transformer and all of the coils that start with "L77xx" on the left side of the sweep board, there is also a jumper staple just above L7711 that must be soldered it does not have a designation number but you`ll see the solder is bad on one end, very common issue with your model.
