Question about Mitsubishi WS-55807 TV

1 Answer

I have a WS-55807 that powers off immediately after it's turned on. I checked the trouble shooting code and the green flash blinked 2x repeated 2x and did that 4 times. What does that mean?

    Thank you for your expert opinion. Now I need your advice. Letting you know that I do not possess the skills to fix it myself. If I was your Brother living in Wisconsin (too far for you to fix it) would you suggest saving the $300+ repair bill and use it on a new TV? or is fixing the TV a better option...especially since I spent $2,100 on it 8 years ago.



    Thanks for your thoughts....

Hi,

The code 2-2 does indicates a short protect fault, which is usually caused by a failure in the convergence section. This is a very common repair in these sets. The typical repair involves replacing the convergence ICs (integrated circuits), and testing/replacing two small pico fuses.

The replacement ICs for your set are part number: STKxxx-xxx and are available from www.encompassparts.com for $19.95 each (needs two). You will also need at least one (likely two) 5 Amp pico fuses. If you wish to repair this yourself, the ICs are located on the large heat sink on the center (Power) PC board. The fuses are also on this board, near the center, location numbers: FXAXX and FXAXX. You would need soldering equipment and very good soldering skills to replace these parts.

An image of the same would be ( the below one is a generic picture ) :-

If you were to call a local shop to repair this, the labor to replace these is roughly $250-275 (in my area) if the TV were brought in to the shop. Please add a trip charge if repaired in the home.

The fuses must be tested with a multimeter to see if they are bad. They are only $2.50 each, so most people without a meter just change them both. If the repair has any problems, like a solder bridge, you may need a meter to check them after that. A good magnifying glass helps prevent solder bridges (for me, anyway).

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I have a Mitsubishi Model WS-65511 the green light on the front was flahing (would not stop) I replaced the 7 Capacitors as was suggested. The light flashed for a while then stopped and turned green


I think I advised you before (on this page you will find a "make a comment button" which allows follow up questions and answers without posting another question.

Green power light now comes on and goes out in few seconds:

On front of set (not the remote) press and hold when that happens both the menu and input buttons for at least 5 seconds and release both.

Power light will blink a 2 digit code like 2 blinks, 2 blinks, pause and repeat that several times---this is an error code---let me know what code you find.

Note: if you have unplugged the set it clears the error codes and you have to plug back and try to turn set on--let it fail and repeat the self check.

When you turn on power you hear a click and the green light turns on. Three seconds later you hear another click and the green light turns off.


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and"menu" buttons on front of tv for at least 5 seconds and then release bothtogether.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Let me know what you find and I will assist you.

When i go to turn the tv on the green light go on and then off. i did the coe test error code repeated 10 times


I found that by simultaneously holding down the remote control "power" button and "volume" button for about 30 seconds the blinking light would go out and a solid green light would come on. Even though the solid green light came on the unit would still not power up. After doing this several times however the unit did finally power up in a normal mode and appears to be working again

My mitsubishi television ws-55807 went out while watching it, what can i do to solve this problem?


If power light comes on and then goes off do the self check this set has:

when light goes off and front of set press and hold both the menu and Input (device) buttons in at same time for at least five seconds and release both buttons.

The set will (the power light) blink a two digit error code like, 2 blinks, 2 blinks, a pause and repeat the code several times.

2,2 is most common error code, let me know what error code if any you find and comment here and I will tell you what it means.

The self check is designed to narrow down where a problem is.

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.

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.

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
