Question Wii plays VC and it shows up like this. how to fix

[tanakorn]

I can play gc and wii normally, but I play vc and it's like this. how to fix it thanks in advance (Sorry for my language. I use google translate)

Check for continuity between all the ground legs on MX, and all the 3.3v legs. I've had some trims where some of the 3.3v legs were islanded by the trim and needed to be reconnected to 3.3v.

Thanks, I'll try the measurements again.

I have tried to measure all continuity, both the ground pin, the 3.3 volt pin are normal.

the 3.3 volt pin are normal.

Hmmm, are you sure about the 4 voltage pins? I see that you have connected pin 24 and 25 together, though you are not powering them directly based on your images.
Pin 27 and 17 are connected on the internal 3.3v plane on the mx pcb, but 25 is not connected directly to the 3.3v plane, but rather through the R62 resistor. So there is continuity, but there should be a high resistance by default between pin 27 and pin 25. Try to power pin 25 and 24 directly to 3.3v instead of going through that resistor and see if that works?

Thanks, at this point I've tried this. But it's still the same.

I checked the continuity of pin 11,12,13,14, is it normal, or should I try to replace the new MX chip?
