My sister had a 13 inch macbook pro and she ended up spilling nail polish remover or something on it when it was about 6 months old and she took it to the apple store and they said that it would be too expensive to fix it so she ended getting another one since she needed it for college. Fast forward about a year and i take a look at and i can see the screen just with no backlight. I had recently purchased a mini dvi to hdmi adapter and plug the macbook pro into the screen and it works almost perfectly. Everything works fine except for a few buttons to be specific (Left Shift button and the numbers 1-4, Their might be more but from my experience that it all i found) My question would be is it a problem with the logic board or the screen? if so how much would it roughly cost to fix. Not looking for anything exact just some info. Thanks advance.
