I have a water damage MacBook Air. I am not sure what spilled on it. It has been damaged for a while now. Apple says it will be $740 for the full repair. The Mic nor the speakers work everything else works perfectly. Is there any way i can repair this? Without replacing the logic-board. I am really just looking for the cheapest way to get the speakers and mic to run. I could open it and whip it down, I am not sure that will work but i'm open to everything. Is there any diagnostic system that can tell me what is fired. I have done a hardware diagnostic but only the 20 min one. not the 2 hour scan. ANY recommendations will help. -Thanks
