I cut outside the lines, sanded well, but removed the u5 before checking continuity!. now at all voltage points I have continuity to ground... it's my first Wii, and besides losing my u5 I don't have another console to make measurements, help  !!!!

There are a few components along the edge of the trim that you have either cut or partially sanded through. These are most likely the source of your shorts:

Hay algunos componentes a lo largo del borde de la moldura que ha cortado o lijado parcialmente. Estos son probablemente el origen de sus pantalones cortos:

I removed or cut and sand?

You should remove the damaged components along the edge. They are not required for the system to function, so removing them won't break anything

Debe quitar los componentes dañados a lo largo del borde. No son necesarios para que el sistema funcione, por lo que eliminarlos no dañará nada.
