I've started to have a problem with the King Air that I never noticed before, and wondering if others have seen the same.

When I start from cold and dark, and fire everything up, I still get no response from the PFD, and a bunch of items still show up as warnings.  Even if I go back to the checklist and go through it all double checking everything, I still see the same.

Do you switch on avionics master?

I do

Bug; switch on the EXT Power to the left of the Avionics Switch. Leave it on during flight.

Hmm, the ext power is on.  I guess the only answer is don't start it from cold and dark.

King Air works for me from cold and dark. I think I had the same problem as you when I was using an out-of-date version of the working title GX mod. Try updating all your WT mods if you’re using those. 

No, it's all default

Select the King. Fly Now. If screens are blank after switching on, etc, come out the flight and go back in again.

I've tried it several times, But always starting from parked, where it does the same.  If I start at a runway, evdrything is running.

let me try right now.

Actually, I stand corrected.  It seems I'm wrong, because even starting on a runway it does the similar, just not as bad.  I still have red for Park brake (even after released) Oil Press and Fuel Press.  Seems I have had something go very wrong with this aircraft.

No issue for me. I spawned at the parking. Started the engine. No issue. the PFD and MFD are working as intended.  I only have INERT STEP on flashing

Huh, I wonder what to do.

Remove all your mods, restart the sim, and try again.

As amahran says- ditch all other mods and do the process of elimination.
