got a Nanao MS9-29A that the Green Gain does not work for some reason (no change even with full rotation to stops of G-GAIN pot)
Green cut off on chassis works fine
Green gain seems to be stuck a little above center position and tends to bleed through a little
Note the following has been done to troubleshoot but issue remains:
Hot, large and main joints reflowed on chassis and neck boards
full recap on neck board and chassis
tried spare known good remote board and ribbon cable, still get same issue
even tested G-GAIN pot on multimeter and replaced G-GAIN pot on the remote board to make sure I wasn't going insane. No luck.
Any ideas what / where I should try next?
