SOURCE: TV is not powering up and red light keeps flashing

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

my guess would be flyback however your lucky you might be able to see a burnt spot on the board giving you a better clue.

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?

SOURCE: I have a toshiba tz50v51 projection tv. the red power light is on

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.

put your remote down and dont use it. disconnect the power at the plug. wait 30 secs. reconnect the power at the plug and use the ON button of the TV, see what happens. only then try remote. a TV is never OFF unless its power is disconnected even when the remote tells it to go off, its still in standby and what it needs is a proper OFF for a while.

Power problems problem on


I would try a power drain:  Unplug the TV's power cable so the TV is not grounded to the house.  Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens.  If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.
