Press on sony remote in this order "display - 5 - volume dn. - power" to see self diagnostics. But to fix it you'll need a tv repairman to fix the Zero Cross Detect circuit.

Sony kp-57ws520 no picture standby lightblnks 9 times


I don't know wheather you are capable of soldering and desoldering or not or for that matter checking components but most likely d6301 on the G board(power board) is bad. It is part number 6-500-567-21. They say d6116 could also be causing the problem it is also on the g board and it is part number 8-719-081-97.
