The 4 blinking lights is usually a indication of a power problem. You can try to reset it to factory defaults.
Step 1: Remove the power cord.
Step 2: Hold down the power button and Volume down button at the same time. Do this for at least 15 seconds before going to step 3, this will clear all electrical from the board.
Step 3: While still holding the 2 buttons down plug the cord back in. Then about 5 seconds later release.
If that doesn't work and it only stays on for a second or two then the monitor part its self has gone bad.

you can have the inverter board replaced...instead of the entire panel.
KDL 40S2010: inverter part # 178950032, you will also need 2 spacers..part # 289765511
you're looking @ 200-300$ for the inverter and 5-10$ a piece for the spacers.
KDL-46V2500: inverter part # A1251295B
you're looking @ around 500-600 $ for the part

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.
SOURCE: No picture or sound. Red light
Just a correction, it is not necessary that 4 times red light blinking always shows inverter board problem.
It depends on chassis/ model number of Sony bravia tv to what is error code of 4 blinks as it would be mentioned service manual.
I'm Sony tech and can help you, let me know model number written at back of tv to provide you exact info about 4 times red light blinking.
Thanks.

AKB circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on the
A board. In addition, unit could be in IK blanking, try turning up
screen slightly.

I simply followed these steps with a surge protector
press the power button and hold up
Then hold up with the power button
then let go of up
and let go of power
