Toshiba TP50G90, makes a loud popping sound then shuts off. red light flashes

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.

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.

active device mounted to a heatsink.

2)Check horiz drive circuit for weak capacitor.

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!

SOURCE: Toshiba TP55G60 shuts down and red light blinks

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.
Good Luck,

Try cleaning the little fans that keep the bulb cool, the temp sensor will shut it off so not to damage the bulb , the winning sound may be the fan going bad or not working like it should.

The tv made a pop sound and now it wont turn on ans both green and red buttons are flashing ..please help


I had the same problem guys! This is what I did:

My T.V. wouldn't turn on. The standby light was flashing six times, then four, then seven...I called Sony and they told me to unplug it for a couple of minutes, then try it again...didn't work....BUT, I have found a solution:

Try unpluging your T.V. for 4 hours+, then turn it back on. Worked for me! It's called a "hard reset" by sony. I had my T.V. unplugged for the whole day though.

Stove cutoff after loud popping sound


The element burnt in to and arced which is the loud noice you heard red flash of light. It probably tripped the breaker at the electrical panel. Don't turn it back on until someone checks the element and replaces it.

TV made a loud pop


hi,

sounds like a popped power capacitor, its going to have to go to the shop most likely around 100.00 repair. taking the back off yearly and airdusting them helps, especially if you have a smoker in the house. caution high voltage present even when off, the heavy single red wire going to the tube is high voltage be careful.

TV randomely turns off


it may just be a static buildup from the dust.
open the tv and blow it out with a air compressor.
if that doest not work then the circuit may be overloading.
remember it stores a charge for days.
