Recently my TV will work for a short time and then turn off. The power (red) light starts flashing. I have to unplug the TV, plug it back in and then it works for a few minutes then will turn off again on it's own. Anyone have any ideas?
Check or have a repair tech check connectors AP1 and AP2.
Vibration rattles the power supply board (a crappy design, as the board
is almost "floating") and causes the wires in the connectors to break,
and may make intermittent contact. Heat may also cause intemittent
contact. A very common flaw.
I just purchased the TH-42PX75U. It would run fine for an hour, then shut off...I would unplug and re-plug..same story. After much chatting on Panasonics Help chat option...7 blinks means there is a component that is not operating properly. Seems to be a common problem with this particular TV based on my online research. Anyone have any suggestions to make it easier to put this thing back into that box??!!

you guys are going to love me. lol. i figured it out at least for mine. $ ) 1.start by unplugging the tv and everything plugged into it(make sure the only thing plugged into the tv is the power cord). 2. next plug in the usb flash drive with the update or a compatible version of the firmware.
3. now while holding down the up arrow button on the tv remote, plug in the tv and keep holding the up arrow while pressing and holding the power button on the side on the tv until you see the light on the tv go from solid green to solid red and yellow flashing lights. once you see this just sit back and wait a few min for it to force the update and it should turn on when its done.
let me know if this works for you as well or if you need any clarification. also know that step three is a pain to do alone and must be all done within a short period of time preferably at the same time.
I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by: - Unplugging the tv. - Press several times (3 or 4 times) the tv Power button. - Plug the tv back in and press the Power button once to turn the tv on....tv worked!!!
I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster. Good luck! Erick
