Primary Flight Display is Blank

A new problem. I use X box for my Flight Sim 2022 . Blank PFD!! How do you turn it back on??

Hello there, welcome aboard!

We will need to know which aircraft you are using to answer that question.

Cessna Citation Jet and Airbus 320 - BOTH have this issue

Starting from the beginning. Is the aircraft powered up?

Yes I allow the sim to power up the airplane so that it is ready to fly…but blank PDF- Electronics are on

OK. If you have other electrical things (lights, etc) working we can eliminate flat battery.
it seems you are not alone with this problem. Possible solutions involve:
Check brightness controls are turned up.
If you have a dimmer mod installed remove it.
Remove all addons, and if the displays then work, replace them one by one checking each time.
Finally, some people found deleting the aircraft folder and re-downloading it solved the problem.
If none of these work have a good long look for alternative solutions on Google.

Best of luck!
