Quoted from Coyote:Get both new cables - the larger one and the display-only one, just so that you know they're both up to snuff. (You can, also, make your own, which is what I do, but I'm sadistic like that.)
My TZ recently had a locked on flasher above the right flipper which melted the plastic, what a stink. It turned out to be a bad ribbon cable to the 8 Driver pcb and the problem went away when I reseated it, but it came back so I decided to make my own cables too. AliExpress 10 meters x 40 pin cable for $25.50 US. Also bought a bunch of different size connectors <$10.00 for 10. Cut to length and tear off whatever number of conductors you need, stick the connector in a vice , put the cable in and have a new cable in seconds.
