Make sure the manual brake isn't down.

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.

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.

Hi Daniel,

Please check if you can access the "error code operational check" to narrow down where the fault came from.
How to enter to error code operational check.
Note : The TV must be in shutdown and not have been switched off. When the TV is switched off, the error code automatically resets to 12 (no error).
Press the buttons on the front panel "Input/Device" and "Menu" at the same time and hold it for 5 sec, activate the error code mode. The LED light will flashes denoting a two digit error code.
Example : if the error code is 22, the led will flash two times pause and then flash two times and will repeat the error code for five times.

If you can't access the error code operational check , please let me know the exact pattern of the flashes of the led light and its color. Check if it will continually flashes green to give you the caused of the symptoms and best solution.

Good luck and take care.

Error Symptom Problem Possible Solutio

How many times it flashes?. It flashes in Orange or alternately in Orange/Green. This flashing LED has certain count that indicates the error occurs in the printer. To find out how to identify error indicated by flashing LED, please check here ;under article How to identify error indicator. Please tell me soon after knowing how many times the printer LED flashing.
Regards,

most of the time the convergance ic go bad:
but try this:
The 3 flashes of the led when you plug the unit in is the
microprocessor initializing.

This unit has an error code diagnostics.

On the front panel of the unit press and hold the INPUT and MENU
buttons at the same time and hold them down for about 5 or 6 seconds.
The unit should activate it's error code mode.

The led will flash count the number of flashes. It will then pause for
1/2 or 1 second. The led will flash again count the number of flashes.
The unit will repeate this for about 5 or 6 times.

You now have the two digit error code. The first time the led flashed
is the first number of the error code, the next time the led flashed is
the last number of the error code.

12 ----------- indicates no error
21 ------------- X-Ray Protect circuit
22 ------------ Short Protect circuit
23 ------------- Horizontal Deflection failure
24 ------------- Vertical Deflection failure


Most units give a error code "22" short protect circuit. If so check:

Q5A00
C557

If Q5A00 check bad there are other parts that have to be checked or
replaced.

If you are able to do above call a tech to service the unit
