    Are you using an euro power adapter ?

    I don't know for the SFC, but US SNES use DC where PAL SNES use AC. PAL SNES is based on SFC hardware. Gen power adapter use DC too. Maybe SFC works in AC like PAL SNES...

    The SFC uses DC like the US SNES console. To summarise, OP had issues with the original Jp SFC (DC) adapter being used with a step-down transformer, so a 'native' generic DC adapter was sourced (to replace the step-down and Jp 100v adapter).

    Sorry for bumping such a old topic but I'm having similar problems,my snes does have some waves on the video but also has a humming sound and I can't pinpoint the problem.The ac adapter(outputs 10v 850ma) I have is a old radio shack one for nes,snes and genesis but it works fine on my other snes and snes mini.

    I'd suggest you try replacing the 7805 chip. Since the adapter works fine on other consoles and your SNES is the only one affected...

    Using things like MAGICOM puts a SEVERE strain on the 7805 chip and the SNES has only one of it. It get overcurrent when a cartridge copier is attached to the system.

    Hi
    Have you found a solution for this problem?
    I bought a super nes last week and a I got the same moving waves. Even without any cartridge there is the green/purple waves on the screen. I sent the unit to fix but they haven't found the solution yet.

    I think that's a new problem. Probably it's hapenning now because the age of super consoles. The problem is to find what component is causing this. I bet caps!
