Alesis QS 8.1 Main Board Ribbon Cable Position

Post by dndemattia » Mon Jan 10, 2022 6:17 pm

Good Afternoon,

I just finished servicing the keyboard assembly of a Alesis QS 8.1. I wrongly assumed (oops) that the cable connector polarities would either be "keyed" or be noted in the service manual. Some headers on the board are noted with a dot to indicated ribbon position (JP 11, 12 & 13 for example), others are not. Does anyone have a clear picture or illustration of all cabling attached to the internal main board as a guide. Thank you in advance.
