You are a genius!
Many thanks

I have spent so many hours chasing the wrong problems.

Squeezing the IDC connections inside the scope seems to have (almost) solved all of the Logic Analyser problems.

LA Probe calibration still fails, but the logic analyser seems to work perfectly for my purposes, despite calibration fail.

Still a truly terrible logic analyser, but really handy to have more than four channels available on screen.

You’re welcome.

The LA in Rigol’s DHO900 series heads that leader board, by a very large margin.

Nevertheless I managed to squeeze each of the piercing jaws. This fixed the problems with all 4 broken channels.

I am thinking of using superglue to fit back the IDC cover.

A better alternative would be to fit a new cable and connectors. Where did you get the fine pitch cable and the connectors on either end?

My scope is now about 9 years old, so well and truly out of warranty, but is there some place which sells spare parts to repairers? I am in Perth in Western Australia

Sorry I rarely check this forum. I should more often.

The ribbon I got from Digikey and the DK part number is MB68G-1-ND, and the PCB connector I had to get from Mouser, TE Connectivity 1-5111595-9. That fine pitch ribbon was hard to find and I couldn't get both from the same place. The front panel connector is impossible to find, but reusing the old seemed to be OK.
