Same problem here. 5 blinks is video related. I've been told to clean the screen by the lamp, as they could be clogged and causing it to over heat. Going to give thet a try first. I'll post what happens...

SOURCE: standby light blinks 13 times
13 blinks is backlight error.. can be 1 of 2 things, 1st bad inverter board (on left side panel looking from back) it has several plug ins to the panel as it supplies voltage to the backlights.2nd could be panel itself as backlights are built into it they can't be replaced. Inverter is probably around $200 +labor, panel= buy new tv... they are outrageously expensive. Good luck!

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, 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 flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

sorry. Hope you still have a waranty. This is not an uncommon problem with the sony's. 99% chance that the panel went out. Could also be a balance board issue, but usually not. Call Sony for an authorized repair center
