Many thanks to Don and others who responded.
The problem has been fixed, I found a suspect dry joint on the PTT/ATT 
switch.
I also checked the new encoder which appeared ok but I did insert a very 
thin piece of insulation between the new encoder and the control board 
to make sure.

All tests now appear ok UNTIL I re-insert and tighten the two holding 
screws in the Control Board. When these are tightened, the control board 
is pulled about 1/8th inch toward front panel, probably stressing both 
boards, causing the display to be erratic (ELICRAFT instead of ELECRAFT  
for example), and erratic other test results. Stressing the boards may 
be causing movement in sockets where they are used.

Does it matter if I leave those two screws out?
Another option would be to put in longer screws and not tighten them so 
much, or perhaps a better suggestion maybe to increase the spacer length 
marginally, so that there is no stressing.

73,
