I put together this SP the other week and it worked perfectly. A few days ago, it fell about 1ft and a couple vertical lines appeared on the side of the screen. I assumed the ribbon cable came loose, so I've taken it apart and reseated both sides of the cable a few times, and I still see lines.
At first, there were two lines that went halfway down the screen. When I reseated the cable, the lines went all the way to the bottom. Now the line spans most of the screen except the very top. I assume I'm just doing something wrong, but at this point I don't know what, especially since the lines keep changing a bit.
I have another SP with an IPS screen that I can take apart to use as a tester if necessary.
