Screen acting weird after not even replacing it

I replaced an iPhone 8 back camera and took the screen off to do it. When I put it back and I turned it on it had these columns on it and didn’t look right. I have tried cleaning the connections and reconnecting but just changes a bit sometimes. That should be it but just seeing if there’s any other things it could be or if not best way to clean the connections

Did you put the display cable bracket back on?

You’ve probably damaged a screen ribbon removing it. You could try disconnecting and reseating the connections but I doubt anything will change. Probably need a new screen. How did you disconnect them?
