Hi Darryl mclellan, because of the amount of flashes, it is very possible failure in the system of LEDs of back lighting or the circuit that feeds it

G'day Lee, sounds like you may have a 'dry joint' meaning the solder has come adrift, to open the back up will need special tools to fix it. Hope you can get it fixed. Cheers Greg.

Hi,
4 blinks indicated of backlight malfunction. The unit shutsdown to avoid overload to the inverter board.
Check the backlights, busted backlight has a physical indication of fault like blackened end, crack end. You must replaced the busted one and your unit will back to normal operation again.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hi,
Seems its time to replace lamp in your Sony KDF-E50A10
When lamp in TV got weak in result, standby light start blinking and if lamp got broken / dead, you will see lamp light ON.
Lamp replacement procedure is easy and written in user manual, please buy Sony original lamp for TV safety.
Thanks.

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.

If the broadcast is in 4:3 (square) then either you can have the black bars on the side, or the TV can stretch the image to fill the screen.
Nothing wrong with your set. The broadcast must be in 16:9 to fil the screen.
