iSight does't show in system profiler: what to replace?
I've got a Macbook Core Duo, last serial number letters RVMN. This morning I tried using Facetime, and the iSight wasn't recognized. It doesn't even appear in the System Profiler: the USB Hi-Speed bus where it used to be connected seems sadly empty, the green light doesn't shine in my bezel anymore.
Without opening the machine, a Genius I called upon told me it could be the iSight or the Logic Board. It occurs to me that my laptop only froze up yesterday, when I tried to test my new extrnal DVD with handbrake, but nothing capital. My laptop seems in perfect working order, and yesterday, as I told, I was placing calls with Facetime.
I resetted the SMC and the PRAM, dug up my Hardware Test DVD with the original OS X Tiger (I'm on Snow Leopard now) and gave a rapid and a full test.
My computer seems fine.
Since I got charged lots for repairs, with almost no warrant that isn't a logic board issue, I ask to you friends:
Is there a way to troubleshoot who has died between the iSight and the logic board?
Which part should I replace?
UPDATE: A clean install of OS X 10.4 showed me that there's no software issue. It's all in the hardware. However, the "USB Hi-Speed" seems to be the external ports, and there's an empty "USB BUS". Is that where the iSight should be? Is there a way to rule out a Logic Board damage?
Es esta una buena pregunta?
