Hi,

Attempting repairs on an SDS9. On power up it shows an 'F' on the display which i assume means fault. Also the bass drum trigger led is permanently lit, which may be related or not. PSU tests ok. Anyone got any clues on where to start looking??

Fixed!!!!

Found a broken track between ic70 and ic49 and everything is back to normal!
