Question about Mitsubishi WS-55807 TV

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

My Mitsubishi WS-55807 will turn on, but within a few seconds will turn back off. I did the self test (holding the input and menu) and got 2-2, meaning that it was a short protect. As you described I tested the F9A04 and F9A05 fuses. Both fuses tested bad (open). According to your posted solution this means the output circuit is suspect. Is there anyway to test that? Or do I just need to get an entire board? I'm just not sure where to take it from here. Any assistance would be appreciated.

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.

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.

hold the input and menu button down on the front of the set for 5 seconds then release. The power light should start blinking a code. 2-2 is a convergance chip problem

Dm board (power supply) for mitsubishi rear projection tv (ws-55807)


Good day,

mohiuddin;

If the indicator stays on then you may have an DM PCB problem and to correct this do the the folowing:

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
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.

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
