I'd suggest opening it up and looking for a cap that is leaking, or has the wrapping separating from the center of the cap at the top.
You might get lucky with the other 2 C64s. I'd suggest taking a pick, or the end of a mechanical pencil to flick the pins of the chips on the underside of the board. You may just have a loose solder joint that is causing the issues.
