If you want to troubleshoot the cable and screen separately, get a spare/new cable first (given the cheaper price I suppose) and you should be able to pinpoint the problem from there. If you end up needing to buy a new screen instead, you can always resell the cable. Maybe obvious, but my 2 cents nonetheless ;)
Hi, I noticed your question awhile ago and wasn't sure what to advise (as many others probably, since this is the first answer). I've no idea if the sheath is critical or required. I do know that if you get a new top case from Apple, it comes with a replacement sheath sticker from 3M, which is custom-cut and probably pricey to get, if you could ever find it. Then I had an idea: why not simply use an antistatic shield bag for this purpose? The kind that sensitive electronics (e.g. cards or hard drives) are packaged in. I would simply cut out a piece large enough to mask the underside of the keyboard, and exactly the right size so it doesn't obstruct the ventilation holes. You could even punch a few holes in it with an office hole punch if ventilation is a concern. Then attach it with insulating/antistatic tape to the top case, making sure again not to obstruct ventilation openings. (Actually, the hole punches could also serve as contact areas for attaching the tape to the top case underside). WARNING: I've...
I installed that very drive in my A1260 a couple weeks ago and it works great. Although I haven't really noticed much of a performance boost from the SSD part of the drive; but that's probably because I use a whole bunch of random different things during the day and don't reboot very often. Still, a great drive so far. Good luck!
You can hook up your Mac HD to a non-Mac laptop (either via Firewire or USB) but you'll need to make sure your non-Mac machine understands the mac filesystem, HFS. If the non-Mac is a Windows box, you can try this software: http://www.mediafour.com/macdrive
