Hi all! I have a 2007 F150 King Ranch (5.4 4WD if that matters). Complicated story here, but basically I had work done on the truck and when it was returned to me the head unit would not illuminate and there is no sound. The buttons around the screen do not work either. The shop replaced the fuse box, so my initial thought was it was from a lower tier F150. However, the shop and I had a falling out as I haven't had my truck in 4 weeks so I am attempting here prior to going to another shop. Any ideas? I checked all the corresponding fuses and all are good.
