Hi Jeff, The power on switch is a simple microswitch mounted on the frame of the rotary function switch. There is an arm that presses on the micro switch button to turn it on. Sometimes the mechanism just needs adjustment, but the microswitches do get stuck in on. There's a picture of the back of the front panel in the TM-11-856A on page 114 and in TM-11-5820-358-35 on page 79 that shows it a little.
