    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!

    What I'm thinking, based on frequency and resistance value, which is 270 Ohms for similar capacitors nearby, could it be 10-12mF? Correct me if I'm wrong. Still need a voltage value. Or I might be using a 25V one. Any ideas?

    Ok. Thanks. I will resolder the capacitor that I thinking might work well and let you know after running tests:) I've done the same before with A1260 and Mac Mini without schematics. Just need to use a bit bigger voltage and maybe bigger tolerance caps than the original ones, just in case.
