I offered to repair this computer for a family member who had spilled a cup of tea on it; she turned it off right away but unfortunately took it to apple-care techs that booted it up! 1) I tried cleaning it to no avail and realized the motherboard needed to be replaced, so I put in a new one. 2) It booted up but the numbers on the keyboard needed to replaced so I put it a whole new bottom panel. 3) Everything seemed to work perfectly except the wifi, I opened it up again and noticed a small tear in the antenna cable. I purchased a new cable and tested it out without dissecting the mba again and it worked. So I took it apart once again, separated the lcd from the bottom panel and took it apart to put in the camera connection and new antenna assembly. I was very careful and it seemed as though everything was smooth sailing. IT WASN'T: When I boot the computer a white screen (no apple) comes up with the start-up chime, a brief pause and then the same thing, over and over... I tried all of the different key combinations recommended online and I've also tried booting from the external CD drive with no success... Can someone please help me out???
