Hi. I have a A1229 17 inch MacBook Pro. My display flickered/failed, so I got a display inverter online. Here's my issue; I'm using an external display, and I noticed that the iSight works perfectly fine. Does the iSight draw power from the display inverter as well? Does this mean I wasted my money? It was only 9.99, but I'm dreading a CCFL install /:
