Hey guys, I'd like to introduce myself. I'm Steve, I've been doing laptop(mainly)/desktop repair as a side hobby since the Pentium 3. Now I focus mainly on flipping cars. I have always loved my iPhone's and have wanted a mac but it didn't happen until this week. Always been a PC guy. A guy at work had two dead macbooks: a mid 2009 MBP 13" and a 2013 MBA 13", which I ended up buying for a great price. Both "broken". I got the 2009 MBP working, which is what i'm on now, but I'm having trouble with this MBA. Basically, the guy had it for a week or two and spilled water on the keyboard. It drowned and it shut down. Took it to mac and with a giant bill, he decided he doesn't need a computer that bad. It's been a few months, it's had a chance to dry out but the backlight decides to work at random intervals. I'm puzzled at what is causing the problem. I have diagnosed issues with computers before, I'm not a genius by any means but I understand the real idea behind what causes what. The backlight comes and goes as it pleases and there isn't anything I can really do to keep it alive other than when it does illuminate it will stay illuminated for 5-15 seconds if I keep pressing the sound up/down buttons, if not it generally dies quickly. Other keys don't work as well. I'm thinking the keyboard might be shorting out and causing the dim button to constantly stay on(unlikely) or the inverter might be bad but how that got covered with water is beyond me. I ALSO want to note, I've taken this computer apart and cleaned it with alcohol and it didn't make much of a difference though, I did see a few chips with corrosion but no other obvious trouble.
