End of first paragraph - should be ohms instead of volts.

Cecil,
I suggest you check the soldering on the front panel board, be
especially aware that on all ICs pin 1 is soldered, that is easy to miss.
Check the schematic for the front panel board and look at the symbol for
the encoder. Measure to make certain you have 5 volts on the 5 volt pin
(measure at the encoder terminal not the board), then turn power off and
measure the resistance from the encoder ground terminal and ground -
expect zero volts.
