Xbox Series X here. This happened to me for the first time last night, departing Adelaide Airport (YPAD) and all screens went blank, I levelled out and cycled the generator and battery switches to no avail. Hit up ATC for a landing and when circling back all screens came back on and stayed on. I flew for an hour and landed at my destination and shut down. Restarted and flew back to YPAD landed and when taxing to parking screens went blank and stayed blank until I parked. I flew this aircraft earlier in the day for an hour from a different airport and had no problems with the screens. I’ll jump on tonight and see if I can replicate the problem and see if YPAD (add on) is the problem.
