Check voltage between te24 and COM,
if no power or Dyna-Hoist voltage is less than 23V, check
wiring between Junction box (near operator)
and control panel.

If 24Vdc is detected and ribbon cable is connected then
replacement of LCD panel assembly may be required.
CONTROL PANEL CIRCUIT
BOARD.
Disc24V wire (from the J/box) in the control
