Hi. Looking for the schematics and the Boardview (if possible): Video Card AMD 109-C29657-10 Blackcomb 1GB. It comes on Apple iMac 27" A1312 Mid-2011 (MC813LL/A MC814LL/A). I got a capacitor C142 blown and I need to find the right one for the replacement. Or please give me some tips which capacitor could be used instead. Any help would be greatly appreciated!
