Screen flipping when Picade is knocked

Hey, I’m having an issue where if the picade is knocked on the right of the screen it flips upside down. Knock it on the left and it flips back. When family are getting ‘engaged’ in some particularly good games its going mid game which is very frustrating.

I’ve tried re-adding the various fixes to the boot file, and checking all the connections and nothing seems lose. Seems really odd that a software fix in the boot file can be undone with a hardware knock!.

Any help welcome, video in comments to show problem.

Video here, excuse my gumpy face in the reflection!

I don’t have a Picade but for general advice I’d say to go over the connections between the screen and the CPU. If whacking it will flip the screen then it has to be a physical connection issue. Hope this helps.
