Has anyone ever seen this problem before? Any idea what the issue is or how to fix it? bottom screen works perfectly, but anything displaying on the top screen is glitchy/all over the place, I don't know what else to try other than opening it up and making sure the ribbon cable is properly connected I guess.
I did already try adjusting the screw in the back next to the battery- whatever it's called, and all that does is make the screen fade away to white.
