My DS Lite's touch screen is a bit flakey in that it is accurate at the right and left edges, but as you move toward the middle it gets more and more off, seeing your press being a bit to the right of where you are pressing. Calibration is problematic, often making me go round and round many times, and then it ends up like it was before. I decided, rather than sending it in for a $75+shipping repair or buyinga replacement, I'll try the repair myself. Supposedly it isn't that difficult. I'm getting a replacement touch screen and tri-wing screwdriver for $23 total, so if I can do it this will definitely work out well. Has anyone done such a replacement before? Any tips you could provide would be helpful, especially anything I need to know about taking the DS Lite apart and putting it back together? Any gotchas?
