TV won't power up complete, but there is no error code

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.

LED Indication Condition

Off Off (standby)

Green Power On

Slow Blink Green Power Off with Timer Set

Fast Blink Green (80 seconds) > Off Power Off (Cooling fan still working, 80 sec)

LED Indication Condition

Red Lamp Failure

Yellow TV Too Hot

Slow Blink Red TV May Require Service

Slow Blink Yellow Lamp Door Open or No Lamp Installed

Hi Andre,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code to narrow down, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.
Regards,

Hi Gerard,
3 flashes of the led light on most KDL series is a power supply malfunction. To confirm the error code, lets access the self diagnostic screen by following the steps below.

Unplug the unit from the outlet for 30 minutes and then plug it back in and check if the symptoms remain the same. Wait until the led light stops from flashing and then press in rapid sequence the "Display", "Channel 5", "Volume (-)", "Power" button key on the remote control. Self diagnostic screen will be display. Let me know the result.

Hi,
Red led blinks 4 times is an error code that shows that fan is not running in tv, check fans connections and make sure all are plugged properly.
Thanks.

Hi there,

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.

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 Diagnostic 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).

Thank you for using FixYa! Have a nice day and please remember to rate this solution.

Warm regards,

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.

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
