[ICOM] Flickering display - 756 Pro

Corroded or tarnished ground connections would be my guess. Remember even a 
little tarnish can add OHMS to a ground point. We tend to ground everything 
in sight but don't seem to return to service those grounds and the 
connection changes with time, weather etc.

Like others said here also something moves, bad cable or connector etc.

I once had a rig connected to a power supply using crimp on ring connectors 
which i had soldered also and my power dropped to about 1/2.
Even though the binding posts were tight using my fingers I used pliers and 
got about 1/2 turn more. My output power came right back up to where it was 
originally when I assembled the station.

Anyway food for thought.
