Either on of the backlight inverter boards is bad or a backlight has failed inside the panel.

A 4 flash indicates you have a backlight problem. Either the backlight inverter boards have failed or you have a backlight that has failed in the LCD panel. You will need a technician to check the set to determine which is the problem.

I would guess your power supply board is slowly disintegrating. It is hard to tell what it is, until it finishes frying itself out. Plan on replacing the power board soon, 1-3 months maybe.

SOURCE: my sony bravia tv is flashing red stand by light

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.
