    I have repaired a few electronic items by replacing bad capacitors. They will swell or leak out of the top or bottom. If it is the bottom, it is sometimes hard to see, so look carefully.

    Good luck!

    Edit: matching the value of a capacitor is usually not that critical, just get close as you can. But make sure the voltage rating is equal to or greater than the original.

    I'll take it apart this weekend and take a gander. That way I have plenty of time to haul my old crt tv downstairs and wait on parts to arrive instead of reassembling it just to watch tv.

    Not to mention, the whole av receiver will need rewired back to rca and componet cables instead of hdmi.

    From what I read, a bad panel (screen) basically totals it out. Hope that's not the case.

    In other news, I just entered a March bracket tourney and the prize is a 55 inch 4k smart tv. Considering I don't watch basketball, chances are slim I'll win but it was free to enter...so why not try lol

    Also lots of bad solder joints out there. dads stove stopped working, opened the panel and it was a bad connection, a little heat and good as new

    No, but had very high winds so a power spike is possible. No clocks were flashing (all 2 of 'em), but that doesn't mean anything. None of mine go out unless its a complete interruption of service.
    Any idea what a power spike would take out first internally if that was the case?

    Usually something in the power board since it is designed to filter out too-high voltage.

    Start where the power comes in the back and trace it as far as you can looking for anything the looks like it got too hot.

    Meter the power too. There must be a transformer in there. Could be the culprit as well.

    To many times the power spike will come up the neutral line which generally has no protection- solid state doesn't play well with big surges, not like the old tube sets which would mainly absorb and dissipate it.
