ok one of the kids in my house spilled milk on my 17" unibody early 2011 mbp. i took out and cleaned the logic board and to my utter delight and surprise it started again. but it is very glitchy, only some of the keys work, there is a large band through the monitor that comes and goes and its making some strange sounds and other things. I took it to an apple repair place and they told me it would by a $900 logic board replacement. now that i have taken the logic board out a half a doz times i think i can replace it myself but it is still costly to buy a new LB. Any ideas besides that?
