TV turns off after short period off time

TV turns off after short period of time, turns on and off 3 to 4 times then goes off. After about five minutes I can turn it on again, and the same cycle happens. Help Please!

Thermal heats up and tv powers down,then on and down for good. Wait a few minutes and it works for a while before it repeats.

    hi,

    our VS 50501A which is 10 years old and has been serviced more than a few times. has begun doing the same thing. It will power on and display a great picture for approx 2 or 3 minutes and then will power off. I can go back after it has sat for a short while and it will power up again for about the same 2 or 3 minutes. I am assuming it is dead and cannot be fixed without a major investment.

My Mitsubishi Medallion tv stays on for about 10 minutes and then shuts down and won't turn back on until a period of time has passed. It is a rear projection tv about 9 years old. Can anyone help ex


When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

Status indicator flashes 3 short times, then one long red flash


Once the status light blinks 3 times, this is an indication that there's a problem with the lamp. The lamp may need a replacement.

If you replace the lamp, but get the same problem, check the inverter board.

If you're not sure where the inverter board is, then you may need to contact a pro for your safety.

Good luck and have a good evening!

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” 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

I have a LG RU-44SZ61D DLP TV and recently replaced the bulb. After about two months the TV went really dim and then started shutting off. The problem increased to the point where you couldnt have the tv...


DLPs have flow chart trouble shooting techniques to pinpoint exactly why your set isnt completeing the boot sequence. If you would like the service manual for your model let me know and i will post a link where you can purchase a complete one.

Tv keeps turning off


If it's staying on for just a short period of time it sounds like there is a sensor that is giving the unit a faulty condition (Perhaps for reason or due to a fault in the sensor). There are normally a few temp sensors in the TV around the Lamp and Ballast. They may be bad, or the lamp or ballast is just generating too much heat.
