Innolux screen flickering

Hello, I just received my screen in the mail today. When I took it out of the casing, I saw that I had the innolux variation. I performed the suggested mod to the screen, bridging a pin on an IC with VCC, but then when I hooked it up to my pi 0, things looked staticky. Any idea what I'm doing wrong? Thanks in advance.

Pics of the soldering on the pi? I find that grounding the screen beside the av pin on the pi helps reduce interference.

unplug the board from the screen, there are contacts for connecting 5v and GND, and everything will work as it should. I also encountered this ailment

I disconnected the board, and found a 5v test pad on the back. I soldered vcc to that and all the flickering went away. Thanks!
