    Vizio P602UI-B3 no power

    I just recently received this Vizio P602UI-B3 and the owner said the screen went black but still had audio. He started this was a few years ago and it's sat since. When I got it there was no signs of life, not even a power light. I opened it up and immediately found swollen caps, 7 of them in fact! I ordered them and will be replacing tonight. Should I be expecting anything else, or are these likely the only problem? If the guy remembered correctly and that really is what happened, I can only assume they stopped supplying enough voltage for the LEDs which turned off, but still had enough for the rest of the set to operate UNTIL he powered it off.

    Attached are photos of the bad caps.

      Ironically the first photo review for the BOJACKs shows the identical power supply board as mine! They didn't list the model of their tv but comparing their photo to mine you can see it's the same board.

        No, that would be coincidence not irony.
        I'd replace all of the caps with a quality brand not no name shit from the smiley box abusers. There might be more but you didn't add a complete photo.

          I have replaced only swollen caps and nothing else was damaged. I haven't done it enough to say it will be the only thing but, it was for me. Let us know!

            I replaced all 7 of the swollen caps and it works like new! I'm relieved that it was caps and not backlights. Backlights are way more expensive for this tv because of the local dimming.

            I'm impressed with how bright, rich and uniform the image is on this tv. Didn't get to test out 4k tho because the YouTube app is so outdated it doesn't support 4k. I gamed on for about an hour and a half tho with zero issues.
