Those cables are repairable!
Anyways. Had a faulty ffc cable on my 3rd party wkf. Got it
Working on my wasp (so now have a spare)
Rip the blue bit off the end/s.
Chop the end off flush/square.
Rub it back and forth on sand paper until coppers exposed on every pin (will be impossible not to over-expose, but doesnt matter)
Put a dot of super glue on the end and wack the blue bit back on
