Blank FCU and alt sel showing blank

[micstatic]

I've noticed this problem in the CJ4. But just reinstalled the 146. Notice the VHF/NAV is blank. The alt sel just shows a red square with diaganol barber pole like lines. Turning feet dial does not fix. Any ideas? thanks.

@micstatic well it was hardware related. One of my devices had an avionics off mapped to a switch that I don't use. Now I know. Just putting this here in case somebody else finds it.
