| I had that display problem with my Corsair.  There is some switching 
logic on the frequency display board  that comes into play when 
switching bands or modes.  I found a shorted ceramic bypass capacitor 
that was fouling up the logic.

I had similar problem and found a couple of xtals were missing. 
Replaced the missing xtals and still had problems on 10 meters . I 
found that reseating the xtal w/ some deoxit took care of the problem. 
I agree if the jumper on the back is missing it is probably the problem.

 On the back of the older Omni  radio there was a jumper used when no 
external VFO was attached.  If That jumper is missing you will have 
the symptoms you describe.
