I was on my 13" MBA and put it down on the table to watch TV. Picked it up an hour later and opened it up and my screen was like this! It wasn't like this when I put it up, and touching the screen only made it worse. Is my LCD cracked or what can it be? I've restarted my computer twice already in desperation that it would fix it with no luck. If my LCD is cracked, is this covered under warranty? I just got the computer in July.
