I just did a search here and found this thread. My week old Jeep backup camera started showing an all white screen with the back up lines.I got the same exact thing hapoen to me
In my 2021 a few weeks ago. I gave it a hard restart (hold power and select buttons for over ten seconds until screen restarts) and the camera came back after uConnect turned back on.
Only think I did was morning I opened the fuse box and pressed them all down as everyone seems to recommend here. Then later noticed the camera was screwed up. I went back into the fuses and pressed them all down again, no joy.
I just tried the hard reset trick and it's working. Thanks!
My previous car, a 2019 Jeep Cherokee back up camera would go all distorted on me like an old tube TV. I discovered if I opened and closed the hatch back it would fix it for a month or two.
I did not feel like bringing my new wrangler to the deal for service so soon so I hope the fix holds.
Once I got used to having a backup camera, it drives me nuts when it doesn't work. I don't know how I did not run over several people and pets backing up in the olden days.
