Sony kp-46wt520 blinks 9 times

you can use basic power supply diodes ecg 125s or diodes rated at 60 herts at 2.5 amp. these type of diodes are common to alot of power supply diode bridges and if you have any junk electrical boards then you could borrow them used, don't worry they will last longer than the original new ones which were not very efficient from the start.
