Rico is trying to replace the cracked LCD screen on his MacBook Air. He's having issues with the LCD layers underneath the glass. Where can he buy a replacement part for that? Rich says that Rico should go to iFixIt. They not only will show him how to fix issues like that, but they also offer the parts and tools to do it.
Another option is to buy a broken MacBook Air for parts. He can check OWC at MacSales.com. They have parts as well, but mostly for upgrades.
