New blue g-boy REV4U

[randomguy]

Hi everibody! It's the end of summer and I would like to build a blue g-boy rev4u since 6 months.So let's start!
I already begin my g-boy and I weld some wires. (Also, I use a pms-pd 3 and I can't access to the micro sd card, I don't know why.)Another thing , the pcb of the screen is dead like the Wii,so I need to buy another one.I don't know if I need to enable the vga on rvloader or no.
Does anibody knows how weld the led and what led I should use?

New update:
Hello all! I finally install rvloader and the other things I need and,success!It boot!(Alslo,thanks to YvetalGriffin for his help)Now,the next big step is to trimm the wii.I need to do a basic OMGWTF trimm right?I'm so happy to do this g-boy and I hope it will still working after the trimm.Now,I will disassemble the wii.Also,is somebody knows what sanding papers I need?
Does eveything look good for my trimm?
See you next time!

Hi everybody!Today I finally do the trimm and the standing part.Now,I juste need to check m'y voltage and sée if it still boot.(Also, I accidentely remove the r1 and the r2 under the Ldo, I don't know if it still work, if somebody Can tell me if will be cool).
See you next Time!

Hello! Sorry for the long silence and happy new year (yeah I know Inm late) but I finaly test my trimm aaannd it's just heating but I dont have any image on m'y screen.Also, is somebody have a tips for soldering the led and thé ffc connector, I'm open!

Your U10 relocation is really sketchy. Have you checked that it's recieving 3.3v and outputting 3.3v to the via properly?

 

[randomguy]

Thanks for your answer!
I dont check this but, before the trimm, I do my relocation and it was working.I will just check my composite câble because I think I wasnnt solder the good one.

To check the U10's function, you will need a multimeter. You'll need to ensure that the 3 GND pins are all connected to GND, pin 5 is being fed 3.3v, and pin 4 is outputting between 2.6v and 3.3v.

If one of the 3 GND legs broke off, you'll have to use the U9 instead. If connection to GND or 3.3v is missing, you can fix that by just running a small wire from a nearby pad to the correct leg.

For the pin 4 I've got 3.1v and for the min 5 I've got nothing because I was trying ton solder better the pin and it's just give me nothing.I think I just broke the pas, so I will try wit the U10 émulation.

Just be sure to keep that wire short. If the U10 emulation wire is too long it will cause instability

Hello everybody, I try to wire a ws2812 led to the pms ans it doesn't work.I check all the voltage and it's look me good.Does Somebody got an idea of why it doesn't work please?

 

[randomguy]

Finally got my new screen and try it buuuuuut,it's not showing something(I don't know why).I jut wire the voltage line for testing if it,I've got the voltage but the screen is not booking.
Is somebody got an idea of the problem?

New update:with the help of @CrazyGadget, I know actually I just ripped or cute a trace on my screen when I remove the header pins on the sides.So next step is to buy (another ) screen.I think I will take the old 240p screen because it looks esier for me to mod it.
