Question about Sony BRAVIA KDL-40S2000 40 in. LCD HDTV
4 times red standby light blinking shows problem of back light failure for some reason.
Possible cause could be either back light inverter boards are defective or power supply board is not providing proper voltages to that inverter boards to function properly.
Power supply board is available separately but back light inverter boards come along with new lcd panel (screen) and it would be costly fix as lcd panel cost would be more than tv worth.
Let me know your expertise level to provide you further info.
