Without having had a lot of time to work on a switch myself recently I can't be sure, but it sounds like your analysis is spot on. The description of your problem pretty much rules out all problems except the screen and cable. As the screen gives a solid black color instead of a weird color scheme or pattern I believe it to be fine, and the culprit to be the cable, but it might be easier replacing the whole thing anyway. that is up to you. I woud suggest trying to find a replacement cable first and seeing if you can get it working with just that. Make sure you read through the full teardown here on Ifixit. While the switch does have some repairability, it's still easy to tear those ribbon cables (even they did it). good luck on your repair, and I hope you'll get your switch working again in no time!
