as Wizard-Fred advises, it is a Ribbon-cable, sometimes called a Stripline.
Problem with these is, if handled incorrectly they can fail.
The problem then is finding a replacement as often they are proprietry items, e.g. using odd connectors that cannot be purchasaed and/or odd cable lengths.
Best to see if the manufacturer supplies one as a spare.
Alternatively, it might be possible for a local electronic (not pc) repair shop to solder a wire on to bypass a failed connection.
Please advise back on progress.
Good Luck - Keep us posted.
