Each section is 60 nodes, each section has it's own SSC. Out of the 17 flex strips we purchased we've successfully cut 8 of those and 3 have developed the same problem. Testing was done on all 17 strips prior to cutting, all seemed to be in perfect working condition, all 120 nodes on all strips working properly. After cutting, three of the strips, the original nodes 118,119 and 120 (same nodes on each strip) (new node #'s 58,59 and 60) now seems to be not receiving any signal at all.
