I'm in the process of fixing a couple of faults with a DJM500. The
actual faults are straightforwrd, dodgy switches, dirty pots etc. What
has got me stumped though, is the connector used to attach the ribbon
cables internally.

They look like the sort that clamps on the bare tinned wires but if I
lift what appears to be the retaining clip there is no change in the
pressure on the cable and I can't get it to release. Does anyone have
any suggestions?

Thanks
John
