Screen is garbled on my MacBook Air (I7 2.0 1466). Connecting to an external monitor works perfect, laptop works perfect otherwise. Is this just in need of an LCD swap, or could there be something else to check first? Does ifixit have an LCD only available, or only the entire lid?

Looks like the LCD panel got a wack. Did you have something heavy sit on it or bang it. Yes you’ll need to replace the lid assembly following this IFIXIT guide: MacBook Air 13" Mid 2012 Display Assembly Replacement and here’s the needed part: MacBook Air 13" (Mid 2012) Display Assembly
