Hi Jessica,
Today I took 3 of these apart because it had been a while. As you can see I removed my previous advice because it applies to a different (older) calculator. I'm very sorry for that.
The three Ti-83's I took apart were all different, so I assume there are quite a few different types of the same calculator. The bad news is: the display connectors on these calculators are difficult to repair. Ti used adhesive to glue the connector to display and print, and it decays after time. This may be repairable with a bit of heat and lots of patience, but I wouldn't expect a long life of the repair.
