Wrong. Green color gun board "- control voltage rail" cold solder joint. Then a re-alignment. Got a few leaky caps in the mix too. But I'll do that later. Thanks for the help! ! ! GREAT site still.

Check power supply for open micro fuse{s}-- If the fuses for the convergence circuits B+ are open,replace convergence IC,s and fuse devices.Then perform re-alignment in servicer mode.test run.Don't forget--PVAT! solder any/all bad connections.

I have a Toshiba TP61F80, i have had the tv for little less than a year. It is a GREAT tv I love it. My tv is plugged into my home stereo so when i power that on tv turns on as well. I pushed the power...

Try unplugging the unit for 10 minutes, then plug back in and try it. If the unit just has a fault this will reset it and it should work. If it does not solve your problem I have a tip at which explains the troubleshooting process and should help you isolate the problem. Let me know if you need more help. Thanks for using FixYa and for the great rating.

Red power light flashing; will not turn on.

It is very likely that one of the convergence correction chips has gone south on you (either that or a capacitor). What you want to look for is a swollen capacitor , or a burnt resistor near the two large heatsinks on the signal/convergence PCB. The flashing LED is an indication that the power supply has detected a fault, your mission is to determine what that might be. another thing to check out at the fuses on the power supply PCB (these have labels like FXXX were XXX is a number). If you find an open fuse, that will help determine where to look for the fault.

Toshiba 50HX81 projection 'tv- blinking red light

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.

If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

With both of error codes flashing, the problem is trying to figure out wich one to focus on. The flashing 6 code is an indication of HV failure which would then cause a vertical failure(4 blink code). There are so many things that would cause this problem. I can narrow it down to the "D" board to fix your problem. If I were there to troubleshoot it, I could narrow it down further I.E. flyback, HV distribution block. I suggest getting a tech diagnose the exact problem. I wish I could narrow it down better for you. Please take time to rate this solution and if I can be of further assistance, let me know

Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
