    And for anyone reading this forum in the future, here's the exact capacitor I ordered from Digi-key (cost me $0.89).

    football0062!

    I just got the feedback capacitor that you suggested changing in the mail today. I took out the old one (that, even after taking out, still didn't appear to have any bulge in it at all) and replaced it with the new one from digi-key. The TV powered right up! I'm sitting here watching The Office thanks to you!

    Thank you soooo much!

    Sure, how would I go about testing the Vs voltage? I just picked up a multimeter yesterday.

    Re: Lg 50pa5500

    I've unplugged that big power connector and the clicking just continues. So what does that mean? Faulty PSU board? Could replacing the coupling or feedback capacitor fix this (even though it doesn't appear to be bulging at all)? Or just replacing the entire board is the best bet?

    I've carefully inspected all the caps and none appear to be deformed. Is there anyway else I can salvage the board I currently have if replacing that feedback capacitor doesn't fix the issue?

    Thanks a lot!

    Re: Lg 50pa5500

    Hi football0062,

    Thanks for the suggestion, might as well give it a try. I've looked at the capacitor closely and it doesn't appear to be bulged out, but I'll replace it anyway and see if that fixes the problem. If it doesn't then I'll probably just get a working used board on ebay and replace the whole board.

    Quick question though: how long should I wait after unplugging the TV to attempt this repair? I've successfully changed capacitors in the past on broken electronics, but they've always been much lower voltage. I want to be cautious...

    Yes, I hear it clicking on and off, and it happens continuously until I unplug it. The clicking is coming directly from the PSU board. No sound.

    Lg 50pa5500

    Hi All,

    I've got a LG 50PA5500. Was watching TV yesterday and the TV just shut off and when I tried turning it back on it cycled through on/off until I simply unplugged it. I've found someone else on this forum who had the same exact issue, and he replaced the PSU board and the TV came back to life.

    I've opened up the TV, and carefully looked at the PSU board and it seems to me that one of the caps is bulging. Is this assessment correct based on the pics below? If I replace this cap with a new one do you think the TV has a chance of coming back to life or should...

    Hello all,

    My LG Plasma TV seems to have a bad PSU board, but I just want to be sure.
