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.

Unfortunately, this is a failure of the balancer board for the backlight. The unfortunate part is that the balancer is not available by itself anymore, and the whole panel must be replaced, as Sony only has the balancers attached to new panels. You can contact Sony directly to ask for assistance, and it usually helps.
Hope this helps you...

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
Usually answered in minutes!
Step 2: Please assign your manual to a product:
