Question about Toshiba 42HP83 42 in. HD-Ready Plasma Television

1 Answer

TV goes off as soon as it is turned on

The television shuts off after being on for 30-60 seconds. Thank God it is happening while still under warranty. Is this something simple that I'm missing? When it goes off, the red (on) light actually blinks twice every few seconds. I'd appreciate any help anyone can provide

    Singer TV Model 20 LNC. When I turn it on (remote or on the set) the red (Standby) light goes off, I hear as if it is about to come on, then I hear a couple of thumps and the red light comes on again.

    I am experiencing same problem TV shuts off within 60 seconds of being turned on . Red power light on TV gives two rapid flashes about every 15 seconds after set has shut off on it's own. Unplugging the TV and plugging back in stops the flashing power light but does not solve the problem, I once solved the problem by going to menu, arrowing over to the sleep timer and power on settings and playing with those settings seemed to solve the problem (this must bew down within 60 seconds of turning on), but I can not get it to work this time.

The first thing in this unit is to check the ribbon cable that goes from the front control panel to the back ssb board, I would unplug and replug to make sure seated properly. Then try it again. There are alot of screws to take out but worth it if this solves the problem.

Television shuts off after being on for 30-60 seconds.


I just had the same problem with mine (Toshiba 42HP85) The TV was fine and shutoff red light blinked twice, and you can turn it on agin right away then it shuts off again. The problem was there are 2 cooling fans you can here at the top rear of the unit, when they get dusty the bearings wear out and shut off. See if you can here 1 or both fans working. If only one is on, you can get a replacement from coolguys.com for 7.95 ea. model # is on the back of the fan. Replace both while you have the cover off, if that's the problem. The unit shutting off is the computer sensing there is a problem the red light is an error warning. Good Luck!
