Facing TV Problems? Ask a TV Technician.
Hello, and sorry you're having problems.
Offhand, when the TV physically shuts itself off- it is generally a hardware failure causing this, and not something that any settings or adjustments can correct.
Can you please tell me how old the TV is, and also when it shuts off does the power light on the set begin blinking, stay lit, or go out please?
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally and STAYS on. Try this procedure up to 3 times, and please let me know what happens.
If you need further assistance let me know. Please do not forget to click at least a 3 STAR RATING, at the top of the page for my efforts. That is how the site credits me for my work.
