TV won't turn OFF

Hi,
I think your Display card not proper work so please contact LG Technician.

Thanks.

Power off the television. Wait a few minutes, then power it back on. If this does not correct the issue leave the power on, point your remote control towards the Sony television and hold the down arrow button. While holding the down arrow button press the "Power" button. Release the down arrow button and the Sony TV will reset itself to factory settings. Once the television performs a scan on itself your problem should be gone.
Good Luck Ed Pinero

My TV surname off after 5-15 minutes of use. The red light in the front blinks once every 3 seconds continuously. If I hold the power button down on the tv, it will turn on and do the same thing.

a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.

When the set is on, the red light should be off, not on...

did u cheak the input cables does it do it on dvd input as well as others ?

Have you tried to access the menu features and tried to retune the stations on digital, or are you hooked up for analog.
If you don't know about what i speak, give me a yell. [email protected] I believe my remote sensor card is bad. While this might explain why you can't turn yours off, it would not explain the blank picture. If the menu does show, i would think the picture tube is O.K. if the menu does not show, there are some other things to look at.

Hi to all, My 42" Panasonic plasma have the same problem. It turned itself off and now red light flashes 7 times, than after short pause 7 times again. And so on. Any ideas what is wrong??

same frustrating symptoms on brand new 42inch here! tv just turns itself off sometimes without warning or if changing to certain channels. leaves red light flashing for a while then red light goes away. any attempts with remote gives flashing green liht on tv. manual power off and on restarts tv but auto off again. found while manual power on keep changing channel on remote till stable picture appears. then use remote to shut down tv - solid red light indicates standby mode. then use remote to turn on again... till next time it happens. but what is technical fault??
