Welcome to the site, hopefully you can get your problem sorted quickly and you'll come back and contribute more.

If it was me, I would be doing a hard reset, pulling the fuse out, going for a cup of tea, then putting the fuse back in to see what happens. I'm not saying that's what you should do, just what I would do.

My reasoning behind this is that perhaps the little electronic gizmos need a reboot and removing the fuse will remove the power which holds up the current volatile memory.

I don't actually know what the main vehicle fuse is but is there a chance that it does not control the control panel? I've heard numerous people say that pulling the control panel out and removing the connection at the rear.... Cup of tea etc, then re-attach does the job like a computer reset.

Yes, that's what I was driving at, pulling the fuse for the control panel would do the same as disconnecting it, we call it a cold reset in the aircraft industry.
