Mitsubishi hd 1080 will turn on for 3 seconds and

The model you have selected: WS-55805 should have a self check feature: when you turn it on and the green power light goes off: ON THE FRONT OF THE SET PRESS AND HOLD BOTH MENU AND INPUT together for at least 5 seconds and then release both buttons.

The power light should blink a two digit error code: for example: 2 blinks, a pause and 2 blinks--it will repeat the code about 10 times.

error codes for this set:

1, then 2 no error detected
2, then 1 X-ray protection
2, then 2 short protection
2, then 3 deflection circuit problem
2, then 4 vertical deflection problem


2, then 2 is the most common and easiest to fix.

Let me know what you find and if 2,2 I have detailed instructions for repairing that kind of trouble.

I am here to help people.
