I have a 2-battery 12C (CNA00616171) that has almost an entire keyboard row that has quit working. This includes SST over to '-' but interstingly not R/S.
Anyone have any ideas on what the issue might be and if it is possible to fix? When I open it, the board is riverted to the chassis so I am hesitant to explore under for fear of wrecking it further.
Cheers...
