Question about Mitsubishi WS-55513 55" Rear Projection HDTV

1 Answer

WS-55513 will not power up. It resets but will not power up.

WS-55513 will not power up. Went/goes through reset mode where green led flashes, but after cycle finishes it will not power up. Last time this failed it was the HD P/S board. Technician came out and replaced about 4 small electrolytic caps on the board. What do you think?

    Yes. Although it did not fix the problem, it did tell me that I was on the right track of diagnosing my problem. I just forgot the prime repair response...always try the simplist thing first.

Either a bad capacitor or capacitors, or the power board or power supply, or possibly flyback. Any of these would definately cause this problem.

    Couldn't believe the same capacitors went bad again after only about 3 years. So, found where to disconnect reset and other front panel switches. Sure do not understand how pushing the reset button worked in resetting the TV, however when I disconnected the front panel switches, the TV powers up just fine with the remote. Maybe one of the other front panel switches is stuck closed or something, but for now I know it is NOT the HD P/S board or anything else you named. Don't take me wrong, I am not bad mouthing you or condemming your ideas, I had the same thoughts. However, I am glad the TV is working fine, now even though I do not have the use of the front panel switches.

Power will not come on even after system reset. Pushed reset and LED flashes then after it stops flashing TV will still not turn on.

do self check: when it shuts off and power light goes off:

On front of set press and hold both menu and input (device) buttons for at least five seconds and release both buttons.

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

Let me know what error code and I will assist you

TV will not turn on even after pushing reset button and waiting for green light to quit flashing.

I went on line and found out what others have done to resolve the problem and then I did what they suggested and would you believe that I saved $700 doing it myself?

Has power, rest light blinks when depressed, will

If you get a green blinking led everytime that the power is pressed, then you need to pull the EEPROM and send it to Mitsubishi for reprogramming. However, it the green led blinks longer than 90sec after it is plugged in, then you need to look at the caps in the DM module.
