I have a late 2007 model A1229 Macbook Pro 17" and was having dim screen issues. I thought it was the inverter so I bought a new one but that didn't fix it. During my installation of the new inverter, I noticed that the computer would not boot if I plugged the iSight cable in. I just hear some clicking when I hold down the power button. Not really sure how this happened all of the sudden. I've checked and re-checked the cables connections. Plugging in the Airport, Inverter, Antenna and LCD cables, the computer boots just fine. But as soon as I plug in the iSight cable into the motherboard, nothing - it won't boot at all.

Interesting side note, the screen is no longer dim after all of this. The brightness gradually came back as I have been messing with it.

I do not have a working battery so I'm just using the magsafe. Not sure if this has anything to do with it. New iSight/Antenna cables and a new battery are on order.

Anyone ever run into this kind of problem before? Got any tips of things I could try? It would be nice to have iSight working.
