Won't turn on

Self Diagnostics

The V18 Chassis features Self Diagnostics to aid in troubleshooting problems that may cause the set to

automatically turn off or "shut down." The "Timer/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

To activate the Error Code Mode, while the set is OFF, press the front panel "INPUT" and "MENU" buttons

at the same time and hold for 5 seconds. The LED will flash denoting a two digit Error Code.

Note: The Front Panel buttons must be 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 occurred.

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

"22" ... Short Protect circuit.

"23" ... Horizontal Deflection failure.

"24" ... Vertical Deflection failure.

can you please mention your tv model

A blinking yellow for this model indicates the TV is too hot, unplug & allow 30-45 min to cool before re-plugging .
OR: lamp not installed or lamp door not closed. there is a lamp door switch that may not be closing, simulating door not closed

LED Indications

The front panel Status LED provides an indication of

the set's operation and the possible cause of a malfunction.

If an abnormal condition is indicated, perform the

Self Diagnostics procedure.

Self Diagnostics

To activate, press the front panel <ACTIVITY> &<CH

??> buttons at the same time and hold for 5 seconds.

The STATUS LED will then flash denoting a two digit

code.

• 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

(ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.

Example: If the Error Code is "23", the LED

will flash two times, pause, and then flash three

times.

Table 2-2: LED Indications

Error Codes, descriiptions and the most likely cause of

the error are listed in Table 2-3.

Note: The TV must be in "Shut Down." The LED

will probably be indicating an abnormal

condition. If the TV is switched Off, AC is

removed, or a System Reset is performed, the

code automatically resets to "12" No Error.

See the Error Code Log to retrieve a history of

errors.

Note: Use the front panel buttons, not the remote

control.

Note: If there is no response, the front panel may be

locked by a V-Chip setting. To unlock, press

and hold <ACTIVITY> on the front panel for

8 seconds.

check some leak or bulged capacitors at the power supply board then replace it.

I have the same problem, called sony up but they are not responding back. The tv is still under warranty and brought it from Amazon. My situation is same but my led error code is 4 or 5 flashes. Does any one knows what's wrong with it.?

my Sony trinitron kv-g21s2 TV not working . conned to the power blink in TV power indicator led

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

Here's the basic troubleshooting:

1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
2. Disconnect ALL devices from the TV.
3. Press the SYSTEM RESET button and hold for 10 seconds. Proceed if the problem still exist.
   
4. Press and hold POWER and MENU buttons simultaneously for 20 seconds. Proceed if the problem still exist.
5. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours.
6. If it still shuts down, 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.
   
7. 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 "35", the LED will flash 3 times, pauses, then flashes 5 times. The error code is repeated a total of 5 times.

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

When it shuts off. Try doing what's called a self-diagnostic test.
As soon as the television shuts try these steps.

Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds,
activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.

Please do Note: The front panel buttons must be 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.

The Error Code designations indicating a malfunction, or no malfunction, are listed below:
Self Diagnosic Code Description
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).
