One option to try is to try to factory reset the tv, to do this turn the tv on hold the Down Arrow on the remote and while doing this press the power button then release the down arrow button.

12 blinks of standby light indicates 'Scanrate error'. You must have thorough knowledge in electronics to proceed. Actually, this is not a user repairable fault. it is very skilled work.

My Sony Bravia, model KDL-46XBR4's standby light is flashing 6 times. We have reset it 3 times but after several days it shuts down and continues to flash the standby...always 6 times. Can anyone tell...


I am experiencing exactly the same problem. TV turns on but within 60 seconds the screen goes black and the red standby light blinks six times. Were you able to resolve this problem on your TV?

Standby LED blinks 4 times


Hi there,

4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.

Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

Tv immediately turns off


Four flashes indicates a problem with the backlight on the TV. It can be caused by the backlight inverter board (the power supply for the backlight) or by defective backlights in the panel It is USUALLY the backlight inverter board that is bad, but I have seen both components fail at various times. This set is fairly new and should still be withing the one year warranty, so you should contact Sony at 800-222-SONY to get it repaired. Be sure to rate this solution. Thanks!
