Question about Toshiba TP50G90 50" Rear Projection Television
Loud popping sound, then shuts off, red light flashes. most of the time I can unplug it for a minute or two and when I turn it back on it works for sometimes a couple of weeks. Then it starts all over again. This morning it shuts down everytime I turn it on. Light still flashing until I unplug it.
It sounds like its over heating.clean all the fans ,put new artic paste on the cpu

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

1)all TV's I service get the chassis pulled for good visual inspection and soldering any/all suspect connections,esp. any active device mounted to a heatsink. 2)Check horiz drive circuit for weak capacitor. 3)Let me know if you are still on it.....T.

Hiya only1gal! The issue you're experiencing could be caused by either the convergence ic's or the power supply. Either part will cost about $400 to repair. Sorry for the bad news, and good luck!

Check the powersupply for loose solder conncetions. Especially in the protect circuit.
There is a white waffer looking IC that has been known for the pins to pop open from the
high frequency output of the power supply.
The Powersupply is on the right side and pretty easy to tell. Please use caution when
working on this set because the caps in the powersupply can hold a good charge. If you have any doubts about doing it yourself, call a professional and hopefully the pain in the pocket won't overcome the pain threshold.
