I have a problem with the AHRS alignment. Everytime when the AHRS aligns the PFD and ND show no numbers and letters! Dont know what i am doing wrong. Not sure if there is an alignment. Tcas Test is ok. Any idea?

Full names in the PMDG forums please.

 

Do the tutorial, it will walk you through all the steps.  AHRS alignment takes 3 min, the tutorial shows you how to display time remaining for that to happen.

Also, you need to keep the aircraft stationary throughout the alignment process. So you might need to sit on stand for a couple of minutes after engine start until the AHRS has completed alignment.
