Hey guys my speedo in my XF fairmont ghia is playing up. On the digital read out it used to show it goes 60km/h or wat eva i was goin and then it drops to showing 0km/h even though im still driving. To fix it i just put the lights on then off and it comes back and at night the oposite i.e of then on. But now its just gone completely. Could i have knocked something wen working on it?
Thanks

Sounds knacked, Have you ever had it open before? Maybee it's as simple as a loose conection inside the display?

probably a dead cluster
