I've seen that display board be able to take 5v at the jack and likely there's a chance the backlight circuit would need 5v somewhere so that would be a safe choice
Nice glad that's sorted, since it's being tested with the unit open not in a case currently be careful you may encounter interference on the RGB lines when it goes into the case without the tight twisted ground wire around the RGB lines
Ok not the board I thought it was, the other thing to make sure for VGA is the mode pin on the Wii is connected to 3.3v to make the Wii boot into VGA. If your wrapped wire around the RGB is showing continuity to the colour I'd recheck those as well.
Can't tell from the zoomed in pic, could you do a zoomed out pic of the display board for the LCD? Just wanting to check if it's the old BB store screen that had a swapped h/v sync
So I'd advise looking at the main forum section, there's a "Guide Hub", a wii section which you found, a "Model Repository" which will have your necessary info. My models aren't available but there are models to work with here on the forum.
Nice photos but could you do 1 more with the front half of the top of the N64? I don't know if it'll shed light on the issue but one of the pif* chips handles the controllers
So got one of the other screens to document a few things, the LCD itself likely will fit, the driver board might fit its massive it's an off shoot of the chip in the ashida LCD driver so VGA is Wii compatible. The board for the menu buttons will not fit the partybox STL it uses little tacs not...
It's anti piracy measure from Nintendo, it kind of is what it is, if you're using bbloader which is obselete or RVloader which is recommended there's no need to go to homebrew channel
The one I linked is Bill of Materials screen and here it is in stock on aliexpress. Just because OEM is out of stock doesn't mean it really is

That battery is taken care of by a chip that handles the charging and such, the voltage of the battery is passed into the system through this chip, voltages under 3.3v are output by buck converters stepping that system voltage down to 1v 3.3v and so on. There's a chip for 5v that boosts the...
Might help to post a pic of the damage, however if the pin is gone then that would mean you wouldn't be able to pull a signal from the ave. The pad is a non connected pad on the Wii so it doesn't actually go anywhere in the first place.
So really want to throw some info your way to make things easier,
From the trim guide
Voltages
1.25v ~3.1A
1.75v ~0.1A accepts 1.8v
2.5v ~0.1A
3.5v ~0.1A accepts 3.3v
3 of those voltages are extremely low so it's very easy to run those off a linear reg from a closer voltage. On the note of...
