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

NORMAL INDICATIONS
ABNORMAL INDICATIONS (For details perform Self Diagnostics Procedure.)

The blinking red light means set is in shutdown because of a short inside the tv.

Someone to begin would have to open it and check power supply voltages inside the set....that is the first step.

Sony TV LED & Blinking Codes - What Does It Mean When Standby/Timer Light Flashes Sony has provided a "self-diagnosis function" with your TV, that in the case of abnormalities or problems the LED or red blinking light on the Timer/Standby indicator flashes a number of times to indicate the issue.
when there is trouble with your Sony Television set -- it indicates the issue in either the diagnostic mode, or even more commonly by flashing a series of LED blinks or flashes on the front of your television. Each set or frequency of the blinks indicates a very specific problem with the television itself.
Sorry but unless you may be able to repair the television set yourself , please call a local repair shop to the have a repairman sent out,,

Take care and please Remember to rate/vote for us to

the blinking light signifies to a repair technician with capacitors or circuits are having an issue they can diagnose the problem via the amount of blinks in between pauses however it will require a technician and some specific tools and schematics to fix and it may be cheaper if its no longer under warranty to purchase a new one


Hope this helped

i had this with my samsung and my mums instead of pressing red power button press either switch from analog tv to digital button or just press a number

If I remember right the set is blinking a code, dont remember which code, but what happened something on the power board failed and knocked out the 5vdc regulation? The power board will most likely need replacement, this should be done by a qualified technincian or someone who knows how to dissassemble/ repair set.
