Mr. Pepe,
I've got a 2011 Macbook Air in the shop. Fan spins up, Audible Chime, Backlight all working. I've done a pretty complete examination of the board, top & bottom. Checked Traces, grounds good (solid), have some spots that look pretty crappy (without scope), simple continuity check seems good. Those nasty traces still get continuity & nominal voltage, and I can get grounds I've tested with solid tone? I'm kinda bugging out with the amount of "Time Suck" this single board/machine is costing me.
So I'm gonna take a chance that my $30 will get me some kind of hint? Seems like I've got good PP to the display rail? Am I missing something obvious, or should I just same my time & board swap it? I'm at (the better part of..) 90min's right now (not counting typing time). Just over my Bench Fee quoted time, but, don't want to make this a "Rabbit Hole". Any Ideas?
I'll try to post some board shot's in the AM.
Thanks,
John
