logic-board repairs: i have a macbook pro 15 retina 2012 that has suddenly stopped booting properly i suggest it's either graphics or RAM. tried all the resetting steps with no solution. I don't think apple would repair, will just offer replacement or a mad quote. anybody knows of anyone that can do that sort of repair and not break the bank?
i also have 2 macbook air a1466 boards that have been water damaged and show no life so i'd like to get these repaired too.
any recommendations would be appreciated
