    Hello, recently(a week or two ago) a friend of mines laptop, a Gateway MT6728, had juice spilled on it. While there wasn't a problem immediately a week later the backlight didn't come on, but you can still see the image if you hold a flashlight up to it. I took it apart to clean it and see if the video cable had become loose or something, and at first it looked like two of the video pins were missing. But then I accidentally had a magnet too close to the laptop and the screen flickered on for a second since it has a magnetic lid switch, or at least that's the only conclusion I can come to. Is there any way I can test the video cable to see if it's bad or not? Or any other way to test why the backlight isn't turning on?

    Thanks

    Ok, well I got my multimeter and carefully tested the plug that goes into the backlight inverter board, 2 of the 5 wires have power going through them. I also tested the two wires that go to the backlight and there was nothing there so I guess that means either the port on the motherboard is bad or the inverter is...

    Well, my theory is that the juice fried a section of the board. You're going to most likely have to replace the port on the motherboard. Just a theory, and I'm a noob. Wait for an admin to tell you what's up.
