Yeah, the problems start when you have to start "breaking" things to get it apart. I mend computers also. Desktops are no problem, but I dread the phone-call that says "My laptop doesn't work" as that usually means trouble! Getting into them can be a nightmare as they deliberately build them so that when you try to take them apart, stuff breaks LOL.
As I said, slowly but surely is the secret. It always looks daunting at first, but before you know it your new screen will be in place and you'll be screwing her back together again. Good luck anyway
