both are good, not short.
Also I am not getting 220V and on stand by bridge should generate 66V which its isn't...Leave a comment:

FYI, I only need this PSU to turn on Backlights, I am using third party main board as original LG mainboard always go bad after 4-5 months. I only need this PSU to turn on backlights and supply 12V to third part main board.Leave a comment:

Hello,
I have LG 49LW5700 which is not turning on, when I checked there was no standby (3.5V) can anyone guide how I can trace which component is faulty.
Thanks -

sorry I went to sleep, i'll post whole board pic shortly.
Bridge rectifier had 220V in inner legs, that was first thing I checked after relay click.
i'l measure reading again with different meter.Leave a comment:
