B737 blank screen in Cockpit

Hi, Can someone advice me please. Ive bought the 737 Max and i have no issues apart from Autopilot but my friend who bought the same addon cannot get any screens working.
Any advice would be appricated. This is for Xbox!

Thanks in advance

at the gate you need to enable external power (center overhead), if you start from the runway everything should be on.
