Hi Guys, I have a dell 7450 that has a camera issue. the color is we off, little purplish and it has lines running vertically. I have swapped the camera with another machine, and the problem stays with the original laptop. Indicating camera is fine. The original camera also works fine in the other laptop. I have reimaged the machine checked drivers etc to no avail.. I'm thinking either the mainboard or cable. When i look at he schematic, the camera is actually a USB camera going straight to a USB port on the Haswell chip. I expected there may be some additional processor chip on the board that may b causing it. I'm struggling to believe it is the motherboard since its connections go straight to USB. I've also checked the power rails and it is spot on 3.3v. Anyone had this issue?
