Question about Toshiba 50H81 50" Rear Projection Television

1 Answer

Tv shutting off

The tv will shut itself down (but the red light stays on) after a while. Sometimes it takes longer than others. It will not come back on until you turn it off and wait a while. If I just leave the tv on after it shuts down, the red light will begin to blink.

Well my mom was watching tv and it just shut off so then my mom turned it back on thinking she might have hit the power button accidentally. But when she turns it on it started blinking the green light for...


The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

well..the control board has this sort of issue. sometimes, if you turn if off long enough to reset itself, this may clear..otherwise, it's a replacement of a non inexpensive component..

what's your technical ability like?

Heard a pop, tv went off, then doesnt come back on


Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.
