    Vizio P50HDTV10A powers on no video

    Just picked this up for free. The set powers on, led is yellow on standby, when I press the power button, it turns green but nothing comes up on the display.
    Will post pics in a bit. Boards seem to be lg.

    Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

      Here are the pictures. There are bulging caps on the pcs, with some showing leakage.
      This seems almost a clone of the P50pc3d I just fixed, it had bulging caps but it didnt completely solve the problem.
      Replacing the caps on that one allowed it to power on with some display and then with help from the forum, figured out it was the ysus.

      This one shows nothing on the screen.

        I think this picture of the back is better.

          Ok, I guess I should replace the caps then. No one seems to have an opinion.

            I am by no means an expert, but I would for sure replace all bad caps and ESR test the others if you have a ESR meter.

              I don't have an esr meter. I just ordered the bulging caps replacement from digikey.

                This thread has some good info on regarding voltage testing etc maybe worth a read.

                  Thanks vinceroger69, I had already tried disconnecting the Ysus then the Zsus and nothing changed.
                  I've already put the back on the TV and carried it out to the garage as we have company tomorrow for Easter and needed the room.
                  After I replace the caps, I'll install the psu and see if there is any difference. I'll then check those voltages if there us no change.
                  I had read that thread but being new at this I'm still kind of scared testing for voltage when I see numbers that high so I was waiting for advice. Lol
