Hi guys,
I have an issue with the backlight on a PowerBook Duo 230. The machine works perfectly, it boots up and works with the dock station, but the internal display has no backlight. The image is there, but there’s no illumination. I tested the display with another motherboard and the screen works fine.
So the problem is definitely on the motherboard. What do you think it could be? I tried something that you really shouldn’t do because it risks causing damage, connecting the display flat cable while the machine was powered on, and when I did that, the screen lit up. It seems like something related to the backlight control logic or brightness control. Of course, I can’t find any schematics…
