A 4 flash shutdown indicates a backlight problem. It can be acused by a bad backlight inverter board (the backlight power supply) or by a defective backlight in the panel. There are fuses on the backlight inverter board called "picofuses" which will need to be checked in order to isolate the problem to the board or the panel. If the fuses are good, you have to replace the panel (very expensive!). If the fuses are opne, most likely the back light inverter board has failed.

Please count Sony KDL-46V3000 standby light blinks as there would be interval of 3 seconds between blinks. Let me know how many times light blinks as its an error code.

I am pretty sure this is a Back Light failure or a bad Ballast. If it is the only fix is to replace the LCD Panel. I would contact Sony at 1800-222-Sony and see if the could help you with repairs and also to get a Factory Service Facility near you to confirm the problem.
Hope this helps,
