Hi, I recently changed the screen in my old laptop, and the new one is stuck on a low backlight brightness. I can do the functionkey + up to tell it to change and it registers that I have done it but there is no change. The screen wasn't a recommended replacement part but I thought it is the same size with same connectors, so I can't go too wrong. 

Anyway, I was just wondering if anyone knows weather the backlight control (Which I assumed was on the inductor board bus), comes from the screen or from the motherboard? I am guessing it must be the screen must incompatible or something.

Thanks, Daniel.
