    LG 50PA4500 power suply trouble shooting....

    Hey guys,

    I have the clicking problem like lots other peapole but the question is not directly related with this problem even if it'a a parts of it. I just did test the power suply board it self on my work table and if i plug the power cord on it i get 47 volts on every pin of both connector, the one going to the ZSUS and the other going to the main. After i did re-instal the board on in the tv panel, plug the power cord on it without pluging any of the 2 boards and i get 0 volts on any of the pins conectors. Unscrew the panel then test it again in place but without any screw and back to 47 volts on every pins. There is something i don't understand here.... Thanks
