    I have the same thing I checked all the pico fuses OK. For open but how do you check for a shorted fuse? I do check from fuse to one of the heat sinks and I did have some.

If you are handy with a multimeter you can check all of the pico fuses the little green 5 amp fuses. Most likley you will find one of those shorted F95A01 most likley but could be another. You will need to change this and also your convergence amps. These three parts are most likely shorted in your set. You are looking at about 250-350 from a competent repair shop.

MY WS-55807 TURNS ON FOR THREE SECONDS AND THEN IT TURNS OFF. I UNPLUGGED IT FOR A WHILE AND STILL THE SAME. I DID AN ERROR CODE OPERATIONAL CHECK AND I CAME UP WITH TWELVE WHICH MEANS NO ERROR IF I AM...


if you unplugged it you will only get the no error code 1,2.

Plug back and turn on, when light on power goes out try it again--if power light goes out there will be a error code.

TV won"t stay on turns off in 3 seconds WS 55807


Do the self check when power light goes off.

On front of set press and hold both the menu and input buttons for 5 seconds or longer and release both buttons.

Power light will blink a error code like: 2 blinks, 2 blinks, a pause and repeat about 4 more times.

Let me know what error code you find and I will tell you what it means.

If this information told you something rate this solution as very helpful as I do this here for free.

Won't come on


The power board has failed and will need to be repaired or replaced. you can remove this board and, replace individual parts and save a lot of money. You will be inspecting for swollen capacitors and resistors. also, look for discolorations on the board itself.

Mitsubishi WS-55807 turns on but then powers back down after a few seconds


Good Day;

The fuses tell you that circuit has failed and was drawing too much current. No other test is needed.

Good Luck, big Irish.

Good Day, Girl 1;
Hey, Girl 1, I have four girls not counting my wife . So, helping you may be difficult. Just kidding!
I would highly suspect that you have fluid on your TV's PCB's (printed circuit boards).
So, at this point that you should call an Authorized Service Center and have them give you an estimate before any repairs are performed.
If you want to try repair on your own e me at mmrkcar@yahoo.com.

Thanks you and Good Luck, big IRISH.

WON'T STAY ON


That is a typical problem in the power supply. It could be a switching regulator that has i think 7 pins, but it gets the power supply up and running with around 157VDC. If that is missing the set won't power up at all. Where are you located. I'm in Louisville Kentucky. Let me know if that works for you. Keep in mind there are quite a few fuses in there too. so check those. I think on that model there is 7 or 9 fuses to check. Talk to you soon. Jay
