I have a HP pavillion Xh555 laptop, I bought it knowing it needed a new video cable, (it cost 49 american, plus shipping and what ever there charge for duty, so what $100) (and I dont want to spend this) well I know the screen works, Hp inovations came up on it a few times, well I took everything apart LCD screen and I disconnected the cable from the back of the LCD and from the laptop base, I noticed that a few wires were cut, I fixed these but, there is on wire with no plastic on it, (Im guessing this is some sort of ground wire, its ok were it comes from the back of the LCD but its half gone and I need to know where it connects to into the laptop........any help would be great P/n # is DC025016100

in the connector that goes to the back of the LCD, there are 18 wires, and the connector that plugs into the base of the laptop there are also 18 wires, this spare wire seems to be just in the casing that wraps all the wires,
