    I am not sure if I have the same model (I am at work right now) but I have the same problem. You have to kill the power (unplug), plug back in, and it should come back on. Repetition may be necessary. I have added one of those CHristmas extension cords that has a "kill" button on the florr because I've had to kill the power so often. A TV repairman could not isolate the problem in my house but offered to take it to his shopp, which I declined.

    Set will not turn on or off. Red power indicator light begins to flash after 10 seconds when set is powered. The first time this happened, I was able to resolve problem by disconnecting then reconnecting to wall outlet. This no longer has any effect.

Flashes of standby light is fault indication. Count it and confirm the number of flashes occurs at one time switch ON. If you wish to get more details about these blinking codes to Toshiba sets, check this link. Pull up older posts there.

Toshiba TV won't turn on


Toshiba? Suspect that if it uses a Lamp for brightness (a model number would help) it may have failed----customer replaceable and if remove look to see it is not shattered inside--2 year, 2000 hour life is normal.

Toshiba 42H81 Blinking on and off light


Very common problems with this TV set. Toshiba even has a technical bulliten on this and several other models of tV set. The negitve terminal of C809 and C810 need to be soldered, as there are no eyeletes in the printed circuit board. This problem could also take out the fuse, F860. Replace if necassary. Good Luck
