I bought my TI book 18 months ago as well and have had the following parts replaced:
on 8/16/04 - 630-4425 (P88 MLB ASSY 1GHZ)
my screen wouldn't come on so I'm guessing this is the logic board?
on 1/25/05:
675-0018 - PBG4, ECN, CASCADING
646-0142 - DSPL, LCD, 15.2, AU, PBG4
810-1703 - BZL, ALUM, PNT
603-2101 - FAN ASSY, PWR SPLY, PBG4 (SUNON)
603-1965 - MAIN FAN ASSY, PBG4 (CHENG HOME)
these were do to a broken left hinge and a high pitched, squealing noise coming from the top right side (out of the vent). The actually gave me a Aluminum screen it seems which of course fixed the hinge problem, but the fan replacement didn't help in my high-pitched, squealing noise b/c it's still doing it and I'm waiting on my 3rd applecare box.
