    Absolutely. I have a multimeter now, so I can perform more troubleshooting. One I think the problem is the switch, the other isn't supplying enough voltage to the chips, though the voltage regulators are outputting the correct voltage.

    Subject: Two Commodore 64's that wont power on

    I have just received FOUR breadbin Commodore 64s. One is missing the
    mainboard, one turns on, but with a black screen, and two don't turn on
    at all (power LED does not light up).

    When our lockdown ends, I'm going to get a multimeter, but I'm wondering
    if there is a common and obvious cause for this that I could look at
    before I get a multimeter (which may not be for weeks because our state
    premier likes to imprison us).

    I've looked at the fuses, one was broken, but putting the good fuse in
    both machines didn't work.

    No specific idea. But the Youtuber Adrian's Digital Basement <https://www.youtube.com/channel/UCE5dIscvDxrb7CD5uiJJOiw> fixed a lot of dead or half-dead Commodores 64. Search his channel for "Commodore 64",
    may be one of the videos is helpful in your case.

    +1 I've learned tons of c64 facts from this channel.
