Cause: While reaching for the volume control, static discharge internally shorts pin 59 (AF-VR) of Q4012, to ground. Q4012 (CPU) is located on the panel Unit. The volume control CW pin connects to +5v and when the volume is turned up, the +5 shorts to ground through the volume control and Q4012. Cure: Replace Q4012 (Part number G1093882). To protect the front CPU from static discharge, add a ground lug and wire to the volume control and connect the other end of wire to the chassis.
