Question about Toshiba TP50H50 50" Rear Projection Television
Hey all i came home the other evening and turned on my tv and nothing just a red power light and no video... i hear static in the speakers... i checked the fuses and all checked good... sounds to me like a high voltage problem but i really want to know if it is worth getting fixed or just buy a new one.. thanks
I have the same problem on the same TV - nothing shown on screen, blinking red LED (sometimes slow, sometimes fast), clicking noise of a transformer. I got the TV free thinking I could fix it. It looks like the previous owner has replaced some resistors. Can anyone double check the pic and tell me if the mod is correct or not? PCB is marked PB9582 B Thanks

You will need to trouble shoot the start up and shutdown circuits. Often this is a minor component failing causing the set to not power up or go into protective shutdown. Do you have the service manual for this TV?

It could either be due to the convergence Circuits ( If the Power Indicator Blinks) or the power deflection board if it doesnt blink. I have a source for parts if you would like the link.

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.
