My tv won't turn on. When I try to turn it on the red power light blinks but the tv doesn't power on. I have unplugged the tv, waited several minutes, and tried again. Same result. What is going on here?

Check the lamp door (with green on) ,.. both green and red blink - bad lamp. Green off, red blinks..Try unpluging for 2 minutes and retry - if no different (sorry, call a service person).

Tv turned itself off and started blinking red light. i unplugged tv and waited and then plugged back in and waited for the blinking green light to go off. turned tv back on and it worked all day. today...

Try removing the projection lamp and reinstalling it. After you reinstall the lamp look for a small reset button near the projection lamp compartment. Could be on the right or left side.

Philips 32" tv won't stay on

Quite possibly one of the heat sinks has come loose or a power supply cooling fan has failed.
Have you tried blowing it out using canned air?

TV won't turn on

It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

The infrared receiver light just keeps blinking red and TV won't power on. Tried unplugging for a little while but didn't help.

kindly count the blinking led to diagnose where the fault came from..

also try the initial check....open the back cover and inspect the power supply board for any bulged capacitors inside..

The red "on" light is blinking and the TV

a suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?

3 blinks repeated will mean a problem in the Convergence area.

5 blinks repeated will mean a short on the 140 volt line.

These are the two most common error codes.

Flashing RED lights in Panasonic TVs means a fatal error code. Unplug the TV, wait 1 minute and replug. If the LED still flashes it needs professional service.
