Open Question

My toshiba t.v. a 50hm67 made a loud pop noise after i turned it on today and it was on for about a min. before the noise and then it started to turn off and on then instead of the blue flashing lights they turned red and if you try to turn it on it says that it is broken, I tried unplugging it to see if it would reset but it only did the same turn off and on and then turn to red.

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

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.

My toshiba 50hm67 has no sound


If you still have picture, and the sound was working before this--you may have lost the audio amp chip. I hope you are not running a bunch of external speakers on the tv here--this WILL kill that chip !!

My TV


The loud pop was the $300 bulb exploding. Don't look for any help from Toshiba either. Their customer service stinks as bad as their product. Put the bulb in yourself and then sell to the next ****** that comes along. I made the mistake of keeping mine, because I thought that Toshiba was still a good product. Wrong, next the color wheel went out. It was back ordered forever. When I finally got one I installed it myself. So, it would only cost me the $530 price of the part with out the $400 charge for labor. Run as fast as you can. I now have vertical lines on the screen after 2 weeks. Who knows what's wrong now.
