Power problem my tv will turn on and then after a while shut it's self off sometimes i can get it to turn right back on sometimes i have to unplug it for a day

There is a thermal sensor in the motor which shuts power off if it gets too hot but usually it won't turn back on until it cools down. It seems you might have a defective switch

tv turns its self off i unplug it plug it back in it will flash on not showing picture it u can her it flash on and right back of some times it will not flash in back of tv and i can hit power it will flash and go off every now and then it will come on show picture after being unplugged and plugged back but then shuts off

Most of these sets have a self check feature:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device”(device sometimes is called input) and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

Best Way reset the set,U right it well reboot itself,before u go to sleep unplug the tv,take out the bateries to remote.Morning,plug in and put the bateris back might reset it self.

Using the menu/options button, check whether there is a sleep timer. You may have accidentally set it, and it will shut off the tv at either a particular time, or after a period of time has elapsed.

hello it sound like theres may be a dry joint probably in the power supply you would need a strong light and a magnifying glass and soldering iron and some solder

shaun

take the lamp back out and reset the lamp

What you Have Is a Main RCA Failure you Have a Cathode to Grid Short In your Picture Tube,The Tube shorts and Tells the Miainboard to shut Down...Good Luck
