I replaced the screen with a known good one and it worked for 1 boot
I'm a little confused about this one. I have a Macbook that wasn't outputting video to the screen (but works to a monitor). I took a screen from a parts machine with a bad logic board, and put it on half way (I didn't connect the battery or half of the screws, just enough to hold it in place and turn it on). When I did this, it booted up fine. So I went and put the rest of the screws in, and now it behaves like the old screen, where the backlight come on but no video.
Any ideas?
Thanks
Ist dies eine gute Frage?
