I just finished wiring voltages to the wii for testing, and when I tried to turn it on it just made a weird buzzing noise. Does anyone know what I did wrong? image.webpimage.webpimage.webpimage.webpimage.webpimage.webp



also I did accidentally knock off a capacitor on the PMS-2, Could that be it?

Your wires are stripped waaaaay too far down. The B+ and B- wires being stripped as far down as they are is giving me anxiety, if the conductive sides of those touch at all, it could completely destroy everything connected to that PMS. This applies to all of your excessively stripped wires though, none of them should be stripped much past the solder point.

You've got a bunch of uncleaned flux in your 4th, 5th and 6th picture, you really need to clean this up with some isopropyl alcohol until the board looks like it did before the flux was applied. Just don't be too rough around the wires.

Also, it looks like you're using solid core wire which breaks much more easily than stranded core wire. It could easily be a break in one of your voltage wires since solid core wire doesn't like to flex. I would recommend switching to stranded core wire for everything except for the super small magnet wire as that tends to be more flexible.

Also, I believe I've spotted a short on your composite video port:

Have you also taken care to sand your board as well as the board section that has the port on it? I've seen this before and someone had it shorting to ground on their end of the port.
