TV shuts off ?

Tv shuts off as soon as its turned on.Also known as instant shut off problem.this was very much noticed on Mitsubishi brands TV.


Most of the Mitsubishi rear projection sets made from about 2000 through 2006 have a self diagnostic check feature. It will indicate if there is a error or not and point you in the direction of your trouble.

Based on the error code I or others can tell you more based on the error code and the EXACT model number of the set.

Here is what you do if it turns on for a few seconds and then the power light goes off.

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

PRESS AND HOLD ?Menu and Input"(or device) 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

If someone has one of these codes and needs help let me know.Keep updated here with what code you receive.So i can give you more details.



The above mentioned detail will basically help you know the problem better on your television set.
