When I was reinstalling the MAIN board, I noticed that some of the conductors had lifted from the ribbon cables.? I squeezed them down, flattened them out and got them into the sockets anyway.? The TX adjustment did not go well (see thread about interpreting adjustment instructions).? Today I pulled them out of J2004 and J2005 and found that two conductors may have contacted each other.? That's very consistent with Andrew's comment that I have a ribbon cable fault.?

One one cable, some of the conductors have delaminated only in the first 2 mm from the end of the cable.? Is there enough contact area in the connector mechanism that I could just cut the first mm of the cable and its stiffener off so that the delaminated conductor doesn't fold back or sideways and cause a problem and then plug it in?

Elsewhere I've found advice to superglue the conductors back down.? So I'll try that on the ones that have a longer delamination region.?

If this fails, are these cables something I would have to order from Icom?? Or are there standard conductor pitches on such cables, in which case I could order some material from DK or Mouser, cut the length and width I need, scrape the paint of the conductors at the end, and possibly glue a stiffener to the end, too?

This is probably the most modern radio I've tried to repair.? I don't yet know much about these flexible ribbon cables.? I'm used to the ones made from individual, insulated, stranded wire with 0.5 inch pitch.
