YES! one of the connector has lost the grasp
was a mod done about 8 years ago
(I'm helping my brother with a dead polaris now but IN STUNNING CONDITIONS!)

I think the 7 space is the correct one

IIRC the smaller connector on the right side, wants a 7 contact, usign only the 5 central
(correct me... )

Have a nice polaris day (hey also korg and roland too!)
