You guys are killing me with the negativity and misinformation.
I can do this in under 20 minutes in the middle of the day when not videotaping it. Here is a one hour video detailing the process, which is EASILY DOABLE in under 20 minutes if you're on your game, pull the old one off in one piece, and don't have to explain anything to anyone around a JVC video camera.
ON THE BACKLIGHT
a) You plugged the cable in upside down(I did that enough times). It is counter intuitive, it actually appears to fit in upside down... it's annoying. The copper side has to be DOWN when plugging it into the connector on the polarizer PCB. Refer to my video.
b) You blew the backlight fuse. Check it, if blown, solder on a new one. WIll put up a video on how to replace a backlight fuse & spot it on a Macbook air shortly, but do check other videos for how to do QFN/other motherboard microsoldering.
c) You ripped the backlight cable. You're screwed. Sorry, go buy a new assembly
ON THE BEZEL
It is simple to remove this without damaging it. Simply use the right tool.
In my video, it took longer than usual for me to remove it. I can usually get that off in 40 seconds, I had a hard one that evening or maybe was just overworked and tired... either way, worst case scenario, it can be removed in five minutes. Watch the video, and you'll see the tool I use to do it - costs no more than fifteen dollars at an art supply store.
Also, don't be a lazy !@#, and make sure you remove all the old adhesive. Don't put old adhesive over new adhesive. See how my bezel fits right back in? It practically jumps back into that !@#$%^&*!@@@ when I'm done, because it's clean. It's not fun to scrape adhesive off with my fingernails for five minutes, but it IS fun to save $200. :-) I'll gladly forego a manicure to make $200.
ON THE PARTS
Yeah they're expensive as !@#$ and going down in price. I'm a more expensive vendor and I have them for $110, eventually they'll be $40-$70 just like the 11.6" Macbook Air.
