Check the solder connections on both ends of the leads going
from the VFO pot to the front panel board.  In particular,
check the solder connections of R19 that is soldered to two
terminals of the VFO pot.  If you move these components
slightly while watching the LCD for erratic response you may
be able to find the exact problem source.
