Screen flickering

Recently upgraded my reform classic to the rk3588 module since then I’ve had a problem with screen flickering. For the most part it works fine but occasionally the screen goes essentially black either by flickering or just being black. It’s not completely black but without lighting (sorta like an old gameboy screen). Moving the hinges seems to affect it but it’s not consistent and sometimes the screen starts acting up on its own. To me it seems like a hardware problem and I’m thinking maybe it’s related to the display cable which is very tight since the upgrade. Anyone had any similar problems and/or know a way to fix it?

I have seen thes here as well though the cable here is not tight
