Sony tv red light blink 4 times on 60" WEGA


When your red light blinks four times on the Sony KDS-R60XBR1 60 inch HDTV, this is an error code for a stopped up fan. You will need to check the ASU board to verify Fan1-4 power to the fan is supplied, next check the fan connector to make sure it is properly connected, and finally make sure the fan is not caught in the wires or harness.

Sony 50 inch 3lcd when turn on it goes on then turns off. flashes red and blinks 4 times in standby.


4 blinks is fan error. Just clean the fans near lamp compartment by a vacuum cleaner and check the fan connectors if they are attached securely.

TV will not turn on. Red light flashes 4 times


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.
