Blank screen and blinking red light

Try unpluging the tv for several minutes and then plug it back in and turn it on and see if that helps

i have the same problem. i just replace the power board because of the "green blinking" light. now, light stays green, picture comes on for a few seconds, then blank....

did you fix your problem.

BLINKING RED LIGHT IS ERROR CODE.

1. Unplug set for a few minutes.

2. Plug back in and turn on.

3. When red power light starts blinking--COUNT THE BLINKS.

4. THREE BLINKS, pause, THREE BLINKS (ETC) IS SHORT PROTECTION AND A DO IT YOURSELF repair for some people. I have complete instructions for this repair.

5. 5 blinks, pause and 5 blinks etc is short on 140 volt line and while not as easy as 3 blink error code it points to places to look at.

turn tv on the red power light comes on then goes off again

It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

My Lg 52"tv turn off and on

the blinking standby light should be a help. It should be blinking a repeating code. Can you post that here please?

Thanks,
Dan

I've had my T.V for about 5 years, and the other day the screen just died and I have no audio, but the when I plug it in the red light in the front flashes, have any idea on what to do.
