    • Remove the six screws located on the underside of the system using the Gamebit 4.5mm screwdriver.

    In order to prevent damage to the fuse, make sure that you always cycle the power before doing so with the power supply disconnected.

    There is a step missing from these instructions. There are two philips head screws where the AV/Power ports are on the back of the motherboard that need to be removed before you can remove the motherboard itself.

    I replaced my controller port, thinking that it was the culprit, but my SNES is still having issues. Nothing works for controller port 1 and only a few buttons work for controller port 2. I tried switching out the controllers and the issue seems to be isolated to the SNES itself. Does anyone have any other suggestions for fixing my issue?

    Thanks in advance.

    For those facing a black screen on startup (after having cleaned pins on cartridges and cartridge slot) WITH power light coming on, turn off console, remove power, and try shorting out the capacitor leads. My SNES stopped working suddenly after a single power cycle, and shorting out the leads (while UNPOWERED) revived it.

    Could you further explain how to short the capacitor leads?

    • Carefully flip the unit back over.

    • Locate the seam. Lift and separate the upper half of the case from the lower half of the case.

  3. WHNsH6Ddh1ZiEBUF

    • Remove the two 11.7 mm Phillips #2 screws connecting the power switch to the motherboard.

    There are two models of SNES- the one pictured here, and the other with a large sound board chip behind the game cartridge reader.

    • The power switch is connected to the motherboard near the top left of the console.

    • Carefully pull the connector from its socket on the motherboard. You may need to wiggle it out as you pull.

    • Do not detach the connector by pulling on the wires. This could damage the wires or the socket.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Any tips on how to tell if it's the power switch that needs replacing vs something else?

Look at it for any signs of physical damage, if you don't see any noticeable issues that you can fix then you can try cutting the two wires stripping off the ends of them, and very carefully touching the wires together while its plugged in. BE EXTREMELY CAREFUL WHILE DOING THIS DO NOT TOUCH THE EXPOSED WIRE. If you notice it turn on, immediately stop touching the wires together and unplug the console. This means that the switch itself is broken. If it doesn't turn on, stop touching the wire together and unplug the console. This means that it's likely a power cable issue.
