When you tested the screen on the other system, did you test the inverter with it or did you use the inveter from the other machine? I had a laptop once that looked like the screen had died but it was really just the inverter that powers the backlights. I couldn't see that the screen was working unless I looked at it under bright lights and at an off angle.
