With 3ds and Wii U prices going up I bought a broken Wii U to try and fix. The thing is it just won't turn on. On the faceplate, there's a steady red light and nothing else. No white light, no blue/yellow. Pressing the power button does nothing. It just stays red. I saw some people had issue where the red light would go off for a bit, not here, stays red no matter what i do. I took it apart and disconnected the drive, same red light, won't power on. I checked the big fuse close to power adapter and i get 15V on both sides. Checked the small fuse just past what seems like a filter, 15V on both sides. the other fuse on negative side is also good. There's a small tear in the power button ribbon but none of the traces seem to be damaged and continuity is there.

There's also a scratch on the drive ribbon cable, again, non of the traces seem to be affected and it still wont boot up with the drive + ribbon unplugged.

On the faceplate connector I get two 3.somethingV and one 1.6V. I assume the 1.6v is enable. Anyone knows what two pins i need to short to force boot on the motherboard? Just 1.6 to ground?

It's getting power, the red light means the Wii U is off iirc, the console might just be bricked beyond belief.
(i barely know anything about hardware so dont quote me on this)

This sounds extremely like a broken power button. The issue might be the scratch at the ribborn cable (did you test it for continuity?) or a ripped of part on the PCB (not sure but it looks like at least D3 had something on the PCB which is missing).
