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.

Thta usually indicates a power supply failure. Try unplugging it from the wall for a good 2 minutes. Replug it in and try again. If it doesn't even attempt to power on the screen then you have a power supply failure, regardless it will probably need repairs. Maybe its under warranty / extended warranty?

Manual says problem with SC, SS, or C boards. SC is large board at left when facing rear, SS is large board at right, and C is small long board at very top. You could check fuses on SC and SS. Also, SC and SS should make a buzzing noise(not too loud) if operating. If a fuse is blown, suspect that board is bad not just bad fuse. Search parts at encompassparts.

The 2 blink error for this model is letting you know that you have a standby power voltage problem. 99% of the time it is your power board. If you bought this set with in the last year, you are still covered under warranty. I would call Sony or a Service provider to get your unit fixed at no charge to you.
