Ok, so i just broke my mac book pro A1286 i7 2.66 GHz (Mid 2010). I want to try and take it apart and fix it before i go out and spend more money than i have too. my computer came into contact with water and when i turned it on, ZAP! the screen went blank. I took my laptop to a technician in my area and he said that my motherboard needs to be replaced. There is no visuals on screen. starts up with no picture and no start up chime. I am able to hook up my laptop to monitors and Tv's and get it to work. My questions: is it really my motherboard that needs to be replaced? if so, are the motherboards interchangeable between the 2.4 i5, 2.53 i5, 2.66 i7, and 2.8 i7? If not, what is the cheapest motherboard i can get and where from? I found a motherboard from 2009 for a good price. Will this work? what are the differences?
