    power light blinks and TV will not come on

  • RollinNoxioS Jan 09, 2009

    I have an older 42" rear projection Toshiba. Never had a problem until this past summer. It often shuts down and the power light flashes. Un-Plug it and Plug it back in and it comes on agian. This often happens up to 10 times in a row before it operates normally again. As it is older, I have no intention spending any money on repair if poossible. I think a little Solder and the "Toshiba shutdown circuits and power supply troubleshooter" mentioned would be perfect.

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.

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

Toshiba 55hx70 projection tv problem


How many times does the light blink? It should blink a number of times, pause then blink the same amount then pause. Try to count the blinks then let me know. Also how long does it run before shutting down if any?
