So you want to solder the pcb to the screen pcb? I doubt you will need to do that but all the pads are labelled. Just match them.

As for ground. If running a jumper make sure it is something like this. Ignore the red line. The black wire is my ground jumper wire. If you can't get proper continuity on certain gpio pins wire them to the corresponding test pad like that.

If you aren't getting proper voltages be sure to check the vcc and gnd pads between the pi and pcb and run wires if necessary.

Ahhh ok. So just jumper it like your picture and that will fix the problem with my ground and the screen will work?

Hopefully, voltage issues are usually because a bad ground. This will solve the bad ground problem. Keep us posted.

Also. You can use any ground test pad. I just used one near the shoulder button. But you can use any pad labelled GND.

I soldered it wrong. I re-did it like rodocops picture and it fixed the problem. Thanks for the help.
