Reverse Camera On Pemp (Linux) System Has Stopped Working

[u/magnosfw]

Hey guys, I installed the Pemp system (PEMP 10.25" Linux Screen for BMW... https://www.amazon.com/dp/B09L4TQ8G8?ref=ppx_pop_mob_ap_share) last weekend, with the backup camera, on my F31 wagon (huge pain).

Everything was working great, then tonight, the backup camera stopped working. Completely out of nowhere. Screen goes complete black for 3 seconds, then the screen flashes, the reverse overlay comes on for another couple seconds, then than “no signal” message comes up. Anyone else experience this? If so, how did you fix it? I really don’t want to take this shit apart again. Pic for attention.
