I'm building a G-Wii and wanted to mod the driver board for my LCD

I bought this one: Driver board

But I got this one: Actual driver board

I've tried to follow this guide but I cant find any datasheets on the chips as the guide says

Does anyone have an idea where I should start?

the chips:

[ 1117 0Q1U ADC ]
[ 1117 0P1G 33C ]
[ ATMHK218 24C16N SU27 H ]
[ MP1482DN F5804507 MPSF34 ]
[one is all blank]

Update:
ok so I had some help identifying the chips and came to the conclusion that I had to remove LW3 (you dont see it before you remove the component) and then route 5V to U24

and success!

I contacted the seller on aliexpress and they said that this is the same board as KYV-N2 V6, just a bit different layout - hope this helps

i hope the thread aint super dead.
seem to be having issues with the screen. wondering if its the voltage. i have 3s LiPo connected that ir putting out 11,50 V. the screen seems to be unresponsive, but the control buttons are doing something since the LED changes color from red to green. thought to ask if anyone had issues and the 11,50V is the culprit or it might be something else

First, please don't Necro old posts. Make a new thread for new issues.

Second, I believe you installed the screens ribbon cable upside down. Try removing it, flipping it, and reinserting it.

Third, most importantly... You should IMMEDIATELY disconnect those lipo batteries from the screen and eachother. LiOn and LiPo cells should NEVER be connected to anything without protection circuitry. It is extremely, dangerous; the cells can catch fire and explode.
