Both rear DVD screens in my 2015 GMC YUKON Denali XL do not work. The sound works and the front Screen will play the DVD in park. We had a water leak in the roof from a repair error with the luggage rack that saturated the entire electrical system but it's been several months since that happened and they just stopped working. Of course the vehicle is 300 miles out of warranty.

This sounds like a Communication issue with the Unit, BCM & the Communication Module

Use of GM Dealer Scan Tool is needed to Test & Program......
IF you had prior issues with Electrical, then be sure to take it back to the same Dealer that repaired, as they may have missed something or there could have been "electrolisis or corrosion" where the moisture contacted Electronic Components & they could be responsible.
Also:
There is a CAMPAIGN for replacing the Rear Head Rest DVD's
