    Default How do I fix a Super Nintendo that wont turn on?

    I've been googling and searching for almost a month now and have found almost no useful information. Could someone please give me some pointers. I have both an original and Mini Super Nintendo's with these problems.

    Are you using the same power supply between them both?

    Also can a mod please slide this to Technical and Restoration please.

    It could be the 5V Voltage Regulator that has gone bad, or the fuse is busted. Use a multimeter to check, if so replace those parts.

    Start with the simplest thing first, if he is using the same power supply then logic would indicate the power supply is bad. A bad SNES and SNES II makes me think there's a common related problem between them.

    MrZeem, as much information as you can possibly give will allow us to help you better.

    I love when someone posts a question like this and then
    disappears, never to be seen again.

    Apply to the snes the same principles as my signature.

    Get a known working power supply and go from there. Fuses, regulators, caps...

    The black fuse is the most common thing to go in SNESs. Replace that nd you are usually good to go. It's unlikely the regulator went bad.

    I have used different power supplys between both of them and have plugged them into different power outlets. I checked both of them with a multi meter and they both had power coming through them. If you guys could be a bit more specific on the black fuse. Could you get a photo and circle the fuse so I know which one you are talking about exactly?

    Iirc, when you open a model 1 SNES, right toward the back where the power plug is, you will see a small black fuse that bridges two parts of the board. It should be close to the 3 pronged regulator (the thingy attached to the metal block)near the power input. Memory is fuzzy through, and it may not necessarily be black in yours.
