Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

If the Standby light is blinking at the front panel of the TV, it seems that there is an internal malfunction occurred in the TV. I will forward a link to a page where you can get more information and troubleshooting steps for this issue. http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=C399467 Please perform the steps provided on the page. If the issue still persists then service of the TV is required.

SOURCE: Sony Bravia KDL-40V300 won't turn on.

Unfortunately 5 blinks is a LCD panel error. The only way to fix it is to replace the whole LCD panel. This is the most expensive part in the TV.
part number: 1-802-488-12
List price: $1336.32
Core charge: 1790.00
You could try to replace it yourself but would need to take the whole TV apart by first taking off the back cover, then removing all the boards in order to get to the panel before putting it back together but I would just recommend buying a new TV as the price of the repair exceeds the price of a new TV of the same size.

Sony TV model KDL-46Z4100, standby light flashes 14 times, no picture, no sound


14 blinks to Sony Brand LCDs indicates a 'Backend error'. It means that, the main board to this TV should be checked for fault. In most cases the main board might need replacement, and a software update too. If you wish to know more details about this blinking code, check this link. It has details of blinking codes to several brands of TVs including Sony. Actually the work is a skilled one, need experience.

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!
