I have the sony kdl55hx800 tv the red light comes on after a few seconds and blinks twice, the green light comes on first then switches over to red.I tried factory reset and everything else I can think of.I tested circuit pins from the power board going to the main board I can get 3.3 volts but not 12v I jumped the power on pin to the 3v pin and still no 12volts it clicks on then back off. Does the main board send back the 12volts to the power board when powered on or does the 12 volts comes from the power board?.What do you think is there something else I can test, is it the power board or the main board?I tested the bridge rectifier it test ok. Help, thank you, Victor
The 12 volts comes FROM the power supply board.
