Good Day;

Shutdown at Power Causes: Cause #1 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.

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.

I have no picture or sound when i hit the power button it clicks off


Please do the self check this set has:

When the power light comes on and goes out press and hold both the MENU and Input (also called Device) buttons at the same time for at least 5 seconds and then release both buttons.

The power light will blink a two digit error code--for example--2 blinks, a pause and 2 blinks.

Let me know what error code you find and I will tell you what it means and what may actually be the problem.

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.

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.
