    I have a Mistubishi ws-55807, the problem is it powers on for 2 secs, nothing comes on the screen and then it shuts off. This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems and the code is 2 - 2 = Short protect (short protect monitors low voltage supplies). I checked for open fuses and F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES ARE OPEN. I have the tools to remove the fuses but I am concerned with what else might be out and how to fix that. Please can anyone help?

    The TV powers on for a second or so before it shuts off (front panel or remote). It was working fine the other night. Any ideas?

Good Day,

Try these:

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. Good Luck, big IRISH.

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.
