You may have a bad solder joint either in the power supply circuit or the horizontal driver circuit. I've found horizontal driver circuits with bad solder joints in a lot of RCA Tv's and also in a lot of other brands. Stargazer

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

I push power button and my 1080 series 42 in. mitsubishi big screen shuts right back 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

Tv just goes blank shoots off then i have to turn it back o n


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.
