Hi,
I've got a Latitude E6500 where the screen all of a sudden went blank when I opened the lid Friday evening. The screen was on, and then all of a sudden went off. I plugged in an external monitor and that works fine, so I'm assuming the video card is ok.
Today I took apart the screen and checked the cable in the back of the screen and it was still plugged in. I unplugged it and plugged it back in. I then tried booting up the laptop and the screen came up for a second or two once I turned the power on, and then turned off. I suspect either the cable, the screen, or possibly an inverter. I have the 1900 x 1200 WUXGA CCFL backlit display.
The other possibility I've thought of is the "closed lid" switch that lets the laptop know the lid is closed, however I haven't been able to find it and don't readily seen anything else near the hinges of the laptop.
Any feedback or additional troubleshooting suggestions would help so I don't just go randomly replacing parts.
Thanks!
Josh
