1 Answer

Plasma TV My plasma screen just went black while watching cable tv. The cable box seems fine. The tv screen goes black and the red light for the power button on the tv starts blinking. I try turning the tv off, then back on to no avail. I also tried unplugging the power supply. No help. I turn on the tv, the screen stay black with no pic, and the power light flashes. Please help.

    No. There is no sound either. Just a black screen like the tv is off, but the red power light is blinking instead of on like it usually suppose to be. Basically the tv wont power on. I already checked all the connections and they're good.

    My TV is on HDMI mode and for the last couple of days I have had a black box in the top left corner of the TV. I read that the problem could be Closed Caption Text related, but I also read that in HDMI mode there's no such a thing as CC. Can anyone help me? I also checked to see if it was a CC issue, but it's set on OFF. I also tried PiP (Picture in Picture) but that doesn't fix my issue either. Thank you

    Someone had put a blanket on top of our Panasonic Plasma tv so the light would not bother their eyes while trying to sleep. The tv was on a timer and turned off and now it will not turn back on. I am thinking the blanket may have shocked the tv however I am not certain. Help!!

    We had a bass box sitting underneath the tv for a sound system that we also would unplug from tv to use with cell phone. All of a sudden most of the screen went black except for like 2 inches on each side of screen can barely be seen. Come to find out one of the kids plugged the cable into the wrong spot on the tv and it was feeding into the tv instead of tv feeding sound to the system. That is when the screen went black.

    ok you have defective power supply at the hot side section! and maybe you have defective oscillation circuit thats why your TV is not starting up! check the hot side section if they have B+ supply! then trace it up from the chopper transformer to flyback! maybe you have defective fusibol resistors.

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie

Well don't tamper with it just return it, there is serveral problem that may cause this, most likely it is the power supply board.
