    Sharp lc-52d62u won't power on 5v sub is present

    I had a sharp with a bad psu, i replaced the whole PSU we a new one from shopjimmy
    part# 184wjqz

    i now have all my voltages now correct except pin3 and pin4 that give me 0.24V and should be 12V

    I hear tv clicking and trying to turn on now, but no pic or sound.

    any idea why i am not getting the 12V out of the new PSU now on Pin3 and 4

    We need good clear hi-res pictures of YOUR boards so we can see what we are dealing with, that will be a starting point.
    EDIT: you already have another thread for the same TV!
