My TV went auto shut off and will not turn on.

If the infra red sensor connector was removed and tv shuts off then it is propably a main board issue
Check for software updates first , if not then send for repaire/replace main board .

Consult owners manual.

I'm not a repairman, but I do know that a lot of sudden power-offs happen due to overheating. If an electronic device gets too hot, it has a auto shut off function that kicks in. Try unplugging it for 10-30 minutes and then try it. If its plugged into a surge protector, try plugging it directly into the wall outlet.

hi make sure the lamp door is securely fitted has there is a safety switch, thanks

When the TV dose not see any signal feeding it, be it be cable, video, etc. it will go into standby mode, timer is for setting the TV to turn off at a pre setting time, I use this mode when I go to bed and set it to turn off after about an hour so the TV will not be on all night when I fell asleep.

Picture turned Yellow because the Blue CRT stopped working. Power turns off because the power supply is indicating a fault. you probably lost your HT (high tension [voltage]) power supply on the blue CRT (picture tube). Professional assistance is recommended. HT power supply CAN DELIVER A LETHAL SHOCK even when the set is unplugged.

MAGNAVOX TV ONLY. 5-10 SECONDS AFTER TURN ON AUTO TURNS OFF-NO LIGHT STAYS ON-I AM FRUSTRATED BUT IT SEEMS LIKE THE OFF ON SWITCH JUST CLICKS BACK TO OFF-ALSO DOES SAME THING BY REMOTE

The problem is not a cable one, but a TV function. Pull out your user manual for your TV. My dad just had this happen, and he has a Sony WEGA TV. The auto sap is an AUTO Secondary Audio Program, you need to find the menu to back out of it.

Good luck.

maybe it was on too long. or there is just something wrong inside of it.
