The warranty on this set should be for 1 year. Return it for warranty service. Unless the set was dropped, moving it should not have effected anything. DO NOT open the set sas that would void the warranty.

SOURCE: Standby LED blinks 4 times
4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.
Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.

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.

6 blinks indicates broblem with florecent backlighting. Check and tighten screws on the inverter boards. There are two boards on the upper left and right. Check that the connectors are in good. Check the pins in the connectors that the wires are attached good. This is a start. If this is under a year old or close to that have seviced under mfc warr. Call sony if expired they may help.

try unplugging your t.v for a few minutes, then plug it back in. if it continues check your owners manual or google your issue. this might be the red flash of death. hopefully unplugging it works. good luck!
