sony bravio kdl-46ex723
Okay guys ill try to make this short. I bought a 46in sony from a pawn shop.. I knew it wasn't working but got it cheap.. I plugged it in nothing happened no led light no nothing so first I looked for the schematics and found out the mainboard was defected so I found one put it in and it turned on for bout 5 sec backlight came on. Then all of a sudden it shut down and the standby light started blinking twice.. So I looked at the schematic it say 2 blinks mean its a OVP(overage voltage protection)problem. From my knowledge ovp has to do with the power ic in the power board so I changed the power...
