Sony Bravia TV kdl red blinking led light error codes solutions

This is an error code of some fault inside. Kindly call in a qualified service technician.

kindly count the blinking led to diagnose where the fault came from..

also try the initial check....open the back cover and inspect the power supply board for any bulged capacitors inside..

My TV surname off after 5-15 minutes of use. The red light in the front blinks once every 3 seconds continuously. If I hold the power button down on the tv, it will turn on and do the same thing.

a suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?

3 blinks repeated will mean a problem in the Convergence area.

5 blinks repeated will mean a short on the 140 volt line.

These are the two most common error codes.

hi,
In your tv there some problem with power supply. you have to check the followin voltages. Sub 5v SOS ,Main 3.3v SOS A-Board,DTV 9v SOS , Tuner Power SOS. If any one of the voltage fails it will shows 10 blinks.
ok

Replace the defective electrolytic caps on the power supply and/or replace power supply, check at www.partstore.com That should fix your problem.

Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.
