Turn on tv and after a minute it turns itself off

I have a mitsubishi ws-55807 which turns itself off shortly after being turned on. Sometime it clicks off right after turning on. It never stays on longer than 2 minutes. is there a fuse or something that might cause this?

Check fuses F9A04 and F9A05 (5A micro fuse)on the board in the middle.If one or both are open than you need to change both the convergence IC's (STK392-570)along with the fuses.

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 [email protected].

Thanks you and Good Luck, big IRISH.

WS-55807 power up problem

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.
