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.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.

I also had blown capacitors on my power supply. You can see when they're bad: the tops split or bubble up like a dome. I changed most of the caps, just to be sure, and it fixed the problem. Careful of the larger capacitors. They stay powered for some time and can shock you pretty badly. Good Luck
MY philips tv model number 55PL9773/17 WAS TURNING OFF THE SCREEN AND LEAVING THE AUDIO ON FOR ONE MINUTE. THEN THE YELLOW LIGHT STAYED ON. THEN THE LIGHT TURNED OFF. thEN I TURNED ON WITH THE REMOTE AND THE YELLOW LIGHT TURNED ON AND A FEW SECONDS LATER CHANGED TO THE GREEN LIGHT AND THE TV TURNED ON. AFTER A FEW MINUTES, BETWEEN 10 AND 30 IT DID THE SAME THING. NOW IT IS OFF WITH A BLINKING RED LIGHT PERMANENTLY ON. TO TURN IT OFF I HAVE TO UNPLUG IT FROM THE WALL. I REPLACE THE LAMP A FEW WEEKS AGO AND IT IS FINE.
Unplug,replug,push the popwer buton couples time,see if stable green LED light,should get tv pic& suond back, not replaced the backlight video board it some how die.
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.
my hitachi model number:55fx48b suddenly just stopped. I can unplug the tv, then turn it back on and red led light will come on for 2 seconds and shuts back off! Can you please help me
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.
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.
