Hi regarding the ribbon cable, there is no direct replacement.
But the cable is robust even bend it will not fail.
You could measure the reisistance of the cable from pin to pin.
The main issue is, that many people do not use the HP cable tool, so they damage (the contacts) the female connector on the pcb. Try to pull out the cable a bit and fix it with hot glue, that helped for me in some cases.

If the ribbon is totally damaged you can solder a pcb connector or self made connectors (13 pins are unusual) from precision IC sockets. The pitch is 2,54mm, so you have a great choice on the market.

If one side is Ok, you can solder the male part directly on the ribbon cable and a female socket on he PCB
