I have a Super 6 plus II that has worked correctly within the last year. It has the older style single bull spider. I recently disassembled everything behind the spider to remove broken tips, and on reassembly I noticed a bunch of the segments in the double ring don't work. Singles, triples, and bull all work fine. The target test reports no stuck segments, and the nuts and wing nuts on the target assembly are only finger tight.
With the switch matrix disconnected, I can jump pins together and every segment in the double ring works just fine. I've replaced the connector pins on the target interface board and there was no change. It seems like the only options left are the connectors on the switch matrix, or there's a break somewhere in the matrix itself. The connectors don't look replaceable, but I've never seen them before. I would imagine the matrix itself is not repairable.
I read a lot of past threads, but they were all old enough that you could just buy a new switch matrix and be done. It looks like that's no longer an option for the original spider. Is there anything else I should check here?
