Question about Toshiba 43H70 43" Rear Projection Television

1 Answer

Automatically powers off, flashing red LED

My tv will run fine for a few minutes, then it will power off with a flashing red LED. I have to unplug and plug it back in to get it working again. It will work for 30 seconds or a minute and do the same thing. I suspect something is overheating, as it stays up longer when started cold and shuts down more quickly once warmed up. Any suggestions?

    Additional info: A split second before the screen goes dead, it looks like it loses the red signal. The picture goes green/blue, and then shuts down.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

If the red light flashes at plug in you likely have a main board that is bad. If you have to press the power button before the red light flashes you likely have a bad bad supply board. This will need to be diagnosed by a technician to be sure of the problem.

LG LCD TV Standby Light Flashing Red Continuously


I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
