I've got a 667 DVI TiBook with a burnt SMT IC on its MLB, and I'm pretty clueless as to how to ID the damn thing. I've got some info from other similar MLBs but I still wasn't able to zero in on even what sort of chip it is, let alone what I could use to replace it.
PCB label says Q23 . . . I'm just guessing but does Q# mean a transistor? Yeesh, I can solder but I still don't know jack s**t about this kind of stuff!
Anyway, take a look and if you can help I'll be most grateful:
