How to repair vertical deflection failure

The Error Code designations indicating a malfunction, or no malfunction, are listed below:

"12" ... indicates no error has occurred.

"21" ... X-Ray Protect circuit.

"22" ... Short Protect circuit.

"23" ... Horizontal Deflection failure.
"24" ... Vertical Deflection failure.

you will have to count the blinks, then there is a short pause and then following a second set of blinks this tells what is wrong with set.

Hi,
Most common problem in WS-55819 is failure of convergence output chips and blown pico fuses in power supply section.
You need to read out error code in tv, procedure is as follows:
Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "24", the LED will flash two times, pause, and then flash four
times.

This way you can determine what section got problem in tv and causing problem.
Let me know if you need further info.
Thanks.

It is usually a vertical deflection circuit problem. Here's the basic troubleshooting:

1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
2. Press MENU button. If a small horizontal line appears at the center of the screen, you have lost vertical sweep on your TV. The protection circuit shuts down the picture to protect the tubes from burning a line across them. The intermittent problem may indicate a loose solder. Try resoldering the vertical output IC. The IC along with the B+ feed resistor back in the sweep power supply is most probably bad or has a loose solder.
   
3. Press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
   
4. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "24", the LED will flash 2 times, pauses, then flashes 4 times. The error code is repeated a total of 5 times. Error 24 indicates a vertical deflection circuit failure.
   

Please let me know the code you'll and I'll tell you where the problem lies and how to fix it.

It is vertical deflection failure problem.
Let me know if you want to repair TV by yourself, that requires soldering parts in PCB experience.

Run the diagnostics.

With the TV power cord plugged in, press the 'INPUT and 'MENU' buttons at the same time -- use the buttons on the front of the TV, NOT the buttons on the remote; a diagnostic Error Code Operational Check will begin, utilizing the 'POWER ON' LED (the green 'POWER ON' indicator light).

There will be a pattern of two sets of flashes, with a pause in bewteen flashes; this sequence of flashes will be repeated a total of five times.

The Error Code designations are listed below:

Error Code Description
12 No eror has occurred.
21 X-Ray Protect circuit.
22 Short Protect circuit.
23 Horizontal Deflection failure.
24 Vertical Deflection failure.

I hope this information helps.

This is from my WS65907 service manual.

4. Self Diagnostics
The “Power ON LED” provides an indication of the sets operation, and the possible cause of a malfunction.
1. Initial Control Circuitry Check
Immediately after the TV is connected to an AC power source:
• The LED flashes three times ... indicating the Microprocessor has initialized and is functioning
properly.
• If the LED does not flash ... the Microprocessor is NOT functioning.
2. Error Code Operational Check
Pressing the front panel “INPUT” and “MENU” buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.
Note: The front panel buttons must used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: For Error Code is “24”, the LED will flash 2 times, pause, and then flash 4 times.
3. Error Codes
The Error Code designations indicating a malfunction, or no malfunction, are listed below:
“12” ... indicates no error has occured.
“21” ... X-Ray Protect circuit.
“22” ... Short Protect circuit.
“23” ... Horizontal Deflection failure.
“24” ... Vertical Deflection failure.5. Circuit Adjustment Mode
Most of the adjustments can only be performed using the remote hand unit. Many of the adjustments must
be performed in both the NTSC and HD modes. Video/Color adjustments must be performed in the NTSC
and HD modes, and data must be preset in the 480P (DVD) and VGA modes.

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.

Good Day, Y'all;

First check for fluid on the PCB's, if ok check the following:

This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds. 2. (Power LED may be on after plug in) check for no less than 4.4 volts DC at pin 3 of PC9A21 on the Power PCB, if low or missing replace PC9A21 part # 268P058020. You can try this first then if don't work still:This model is also equipped with a self-diagnosis feature to help with diagnosis of shutdown problems.

Shutdown at power with self diagnosis error 2-2. Check for open fuses F9A04 and F9A05 part # 283P144080 on the +24 and -24 volt lines. If the fuses are open the convergence output circuit would be suspect. 2. Shutdown at power with self diagnosis error 2-1. At power on check for 12-volts DC at connector KH pin 8, if missing check IC9C51 part # 270P990010 and L9C52 part # 441D009020 on the Signal PCB
