Hi, i am new at this so maybe i made a noob mistake. I just trimmed my first wii and sanaded it with sandpaper up to 1500 grit, replaced the u10 and finally i removed the LDO. After finnishing, i cheked the resistances, and all of them were ok except for the 3.3v, that gives me a resistance of arround 1,25k.

I have tried different things like sanding again the borthers, cleanning the board and removeing near to edges components that weren't necesarys, but it still doesn't want to work. If have any advices, i would be very thankfull.

1.25k between 3.3v and any other voltage/GND is okay

i just realized that for testing the board, the power suply i was using wasn't powerfull enought to power my wii, what made my pms turn off. I thought that the problem were the low resistances of the 3.3 v paths, but i was wrong with my diacnostics. I tested the boards with an 18650 cell and it worked perfectly.

resistances with ground : 3.3v = 1,26k // 1,8v = 36,5ohms // 1.15v = 34.7ohms // 1v = 147 ohms
