1. Have you ever had a power failure associated with your communication and/or navigation aids?
Personally, never. There are multiple power sources so a backup gen has always been available, and I've never experienced a failure/short of a common bus, not even in general aviation (I know it's happened to others though).

I'm not going to address specific aircraft types, but in general...
Yes. CRT glass displays occasionally burn out due to age, but there are multiple reversion options to display the data on other CRTs so I've never actually lost the ability to see the data. Also both CRTs and Flat-screen displays have multi-pin connectors which can occasionally suffer a bad connection. On at least some aircraft the display module can re-racked in flight by the pilots without any tools, to attempt to restore a good connection. I'm not aware of any SOP allowing this procedure in flight, but in an emergency the PIC could do so at his discretion.
