Hi, I've got a very weird screen behaviour going on. Not sure if it is the inverter. In a nutshell: the backlight goes off. Then sometimes it comes on again. I don't think it's a graphics card problem - with an external screen, things are fine. Also: If I look very closely, I can see the screen content without the backlight. (Same as when you dim down the display the whole way). I might be wrong, but it seems like on the bottom left of the screen (when it's working), just next to the hinge, the display brightness isn't the same as in the rest of the screen.... though that may be subjective, me "seeing things". As I said - my guess would be: inverter, or inverter cable. What's weird though: 1) The problem started 3-4 months ago, but only happened at a certain screen angle (when it was 2 inches/10 degrees opened). 2) Then the problem started happening at other screen angles. I took the laptop apart, keyboard unit off, everything back together: works fine. A day or two later: buggered again. 3) For some time, I noticed that when the screen goes dark, I could press the keyboard unit down near the FireWire port. That fixed the problem. So I thought: maybe a loose connection somewhere? Sometimes, "pulling up" on the top right screen edge and slightly(!) pressing down the laptop near the magsafe connector, helped solve the problem. (Once the screen was working, I just kept it in that position & didn't touch it. But now all this doesn't help anymore either. Screen's working, I walk away make coffee, come back: backlight is off. A few minutes later it sometimes comes on again by itself... Long story cut short: It's just plain weird.... as if my little Macbook had a life of its own. Any ideas anyone?
