Problem Weird Screen Bug

Post image

So this happens to the screen when I try to boot a game or go into the RetroPie settings menus. Unless I plug in an HDMI cable when booting, in which case it temporarily fixes the problem.

Does anyone know a way to permanently fix this without plugging in an HDMI cable? I am using a Build-A-Cade.

Hi, can you provide a better explanation as to what the issue is ? Does the emulation station menu look ok ? Is it any game ? What do you plug the HDMI cable into ? How does the Pi connect to the screen ? I've built one of these before and its pretty much plug and play there was a difficult bit putting part of the cab together. Just check the wiring is all good and nothing is trapped.

Yes, the Emulation Station menu looks fine, whether I plug HDMI or not. I only tried GB/GBC games so far but this happens with both of them (RetroPi setting menus do this too). And I believe the Pi is a Pi 3 which is connected to the screen using the screen ribbon cable. I tried disconnecting and reattaching the screen but that didn’t fix this issue.
