Hi Everyone-
I have late 2008 MBP, just got my logic board replaced free of charge yesterday after experiencing the same issues (wouldn't wake up from sleep, no chime/fan at start up, black screen, would not listen to pram or smc reset and would not boot up from OSX dic). My warranty was expired by 18 days, but since my serial number matched up to the ones listed with the faulty NVIDIA chips, I was lucky enough to get everything for free. Apparently Apple recalled these NVIDIA chips, although I would not have known this as for the did not do a very "good" job publicizing it. Basically, the "genius" said that the chip fried my logic board and I was assured that I received a new board, not a refurb.
The repair was going to cost me $902.37. I highly suggest taking your machine into an Apple store to see what they can do for you. If they can't do anything, sell your machine in parts (you'll get the most money that way) on eBay...looks like you could get approx $600.
Oh, did I mention that the repair was done overnight..? Less than 24 hours and its back in my hands.
