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.

I would suspect one or more of the miniature flourescent backlight lamps. One way to confirm this would be to power up the set with a grayscale image at 40 to 60 IRE. If one or more lamps is failing to light, a slightly darker horizontal area in the grayscale will give it away. Unfortunately, Sony will not supply any of the backlight components apart from a new LCD panel. Sorry.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Hi,

There is a power fault with one of the PCB's inside, contact Sony if you are still in warranty, if not contact a Sony service center as it will need an engineer to open it up to repair it.

Thanks
