CCFL was replaced, bulb was bright, but only the bottom of the screen was lit.
Inverter was replaced, part determined to be working.
It turns out that a full replacement of the LCD screen was in order. Picked up a replacement for the machine and -- BAM -- Worked like a charm.
Didn't -want- to go that far, but at least the machine is portable again!
Thanks for the assist badtaylorx.
