John, those "could" be your backlight wires. Unless you post an image of your LCD and the connectors, it is hard to say. Without those, you will not have a backlight. Take a flashlight and angle it against your LCD and see if you can see anything on the screen that way. I'd also suggest that you try an external monitor and see if that works okay. Hope this helps, good luck.

You may have to remove the LCD from the back case. There should be either 3 or 4 small screws on either side of the LCD. Remove those to get the LCD out of the case. Fold the LCD slowly over toward the keyboard. Then you should see the "video cable" ( a flat ribbon cable that plugs into a circuit board at the top 1/3 of the panel. If you follow that ribbon cable to the bottom of the panel, slightly to the right of it, you should see the inverter cable and the inverter itself. That cable consist of a pink and a whit cable and the plug that connects to the inverter itself. See if all of that is properly connected. If it is, then you have either a broken invert, or a broken LCD. The best way to test it of course would be with an LCD tester. Those run about 1/2 the price of a new LCD and are widely available.
