3.5 screen to rasp pi 3B

[siguper]

Hello everyone,

I have a little issue with my rasp pi 3.

I want to build the gameboy project with everyting i have at home. So i am working with a pi 3B.



Am i doing this wiring right (black red)? and can you advice me where the yellow and white ones must go?

Tanks

Yes your red and black wire In the right place
( I prefer to use GPIO for power )
[spoiler="GPIO"][/spoiler]
And yellow wire going to PP24
Ignore the white one

Tanks ik will try to get this ready, i will let you know if it worked!

First of all: https://pinout.xyz/pinout/pin2_5v_power a nice neat site for de GPIO pins,

second, i did follow the tips i was getting from you guys. But the screen does not seems to give a signal. it stays, as you can see, completely black. Did i do something wrong or am i forgetting something?

sorry for my high noob levels , first raspberry project.

I did not use adafruti screen before , but in other screens the yellow wire mean Output signel , and i see here it's GND
try to use white wire in PP24
and you should have pre installed os in sd card

[Double0EK]

Im still new to this BUT it was mentioned that the screen will not turn on or show that its on if there isnt an input signal..so you might need to load up RPi3 with an OS to be sure its working.

[siguper]

I have raspbian installed on my sd card. so there is a OS.

is it possible that a setting is wrong in the software?

it still has black screen, even no light.
