There's really only one thing to check, and if it's not that then all that's left would be to replace the screen. On the 7 Pro, unlike my 6 Pro and earlier models, the retainer for the display connector is held in by spring tension, rather than being secured by a screw. Here's a picture of your retainer.

Of course, the only way to check it is to remove the screen. That single connector carries the signals for the fingerprint reader, the digitizer and the OLED display, so if that's the problem then it's still almost completely connected, just not quite.
You'll want to follow the screen replacement guide to open up the screen. Obviously the first thing to check is the retainer; although it seems unlikely, it's theoretically possible for the clip to come loose from a sharp impact such as a drop. If that happens, the force required to jar the retainer loose would probably also be enough to pop the connector out of its socket. So if it's just sitting in the socket without being clicked in completely, that could explain your issues.

I'd say open it up and verify whether the bracket is in place or not. If not, that would reinforce the theory that it's just a loose connector. Either way you'll want to go ahead and unplug the connector. Get out your magnifying glass and a nice bright light and check the pins on the motherboard and the connector, looking for anything bent, missing or broken. Bent pins can sometimes be straightened with some fine tip tweezers, but obviously bent or broken pins are a more serious issue.

Assuming it all looks good, clean both sides with some 90% or higher concentration isopropyl (rubbing) alcohol, give it a moment to dry then plug it back in, fix the bracket in place and test.
As I mentioned, if that doesn't work then about all that's left is to replace what would appear to be a defective or damaged digitizer. Since it's fused to the display, you'll be replacing the complete screen assembly.
Give that a try and let us know what you find. Good luck!
