Hello, I am building my first portable wii, I have read and reread the guides and everything on how to do it to be a little prepared to be able to make my own, and still failing in the attempt, and excuse my English if it seems rude or inappropriate I occupy the Google translator.
-Thank you very much for all the help you could give me.
-install RVLOADER without cutting the wii and it worked perfect.
-cut the wii according to the guidelines, sand thoroughly and go over the edges many times.
-The problems began. I followed the cutting guides and everything was going well until I began to take the values of the resistors in the values of 3.3v 1v, 1.15v with the multimeter in sound mode and in 3.3v ok in 1v ok but in 1.15v I can not make it not sound, and from there I have been cutting and polishing the edges to make it not sound but I cannot solve it, I still connect everything to test the voltages and that they have the correct values. I turn on and the screen makes me a sweep and it does not give me any image, would there be some option to know what failed and if I have to buy another wii, it would be very helpful if you could help me. Here I attach some images and a small video of what happens.

Why'd you trim the Wii into such a funky shape? It makes it a bit harder to diagnose problems like that.

Anyway, to identify if you have a short on the 1v & 1.15v lines you need to change the range on your multimeter to 200 ohms. The nominal resistance between 1v/1.15v and ground is less than 50 ohms, which will cause most multimeters set to auto-continuity mode to beep even though there is no short.

¿Por qué recortaste la Wii en una forma tan original? Hace que sea un poco más difícil diagnosticar problemas como ese.

De todos modos, para identificar si tiene un cortocircuito en las líneas de 1v y 1.15v, debe cambiar el rango de su multímetro a 200 ohmios. La resistencia nominal entre 1v/1,15v y tierra es inferior a 50 ohmios, lo que hará que la mayoría de los multímetros configurados en modo de continuidad automática emitan un pitido aunque no haya cortocircuito.
[/CITA]
Probé con el multímetro como me dijiste, lo puse en una escala de 200 ohmios y desconecté todo, estos son los valores que me salen.
-3.3v = nada
-1v=97,8 ohmios
-1.15v= 72.5 ohmios

It looks like your translator isn't working right with the forums, it would be best to copy your post into google translate, and copy / paste the response here in English. Right now, your response is being included in the quote and it's all in Spanish.

sorry here it is edited
I tried with the multimeter as you told me, I put it on a scale of 200 ohms and disconnected everything, these are the values that I get.
-3.3v = nothing
-1v=97.8 ohms
-1.15v= 72.5 ohms

1v seems pretty normal to me. If anything, 1v15 seems a little high, I usually get something around 20-30 ohms. Believe it or not, sometimes having shorts on the edges of the board can cause higher resistances on the voltage lines (at least in my experience).

For 3v3, you're expecting something around 8k ohms, so put your meter in the 20k range.

When you sanded your edges, what grits dod you use? Ideally, you'd start around 120 (or even 80), then 220, 320, 400, 600, 800, and end on 1000.

For the end, I only used 800 grain, I don't have 1000, I sanded the edges of the Wii many times with 800 grain. And even so, I can't get my Wii to give me an image, it gives an image like a sweep as if I wanted to take and in the end it doesn't. I really don't know what else to do.

Honestly, 800 should be fine for a 4 layer Wii, the 1000 is just a finisher to be 100% thorough. Thr bulk of thr sanding should happen at the lower levels, I usually aim to have clear layer separation by the 320 mark, and everything after that is smoothing it all out.
