We have an old white DS Lite that we bought for our son way back in 2006, shortly after launch. It has since been inherited by my daughter, as our son got a replacement unit last year. Our daughter will be getting a new pink DS this Christmas, to replace this old one that currently has two broken hinges and a floppy (but still fully connected and fully functional) screen. I have ordered a new green shell for this soon to be spare DS Lite, and will be following directions in the online guides and hope to correctly to dis- and re-assemble it. This will obviously fix the mechanical problems. There are a couple of other issues, that I have noticed during gameplay, which I'd like to address while I have the unit taken apart. I am wondering what the best way (if any) to address these is. 1. This DS Lite sometimes has a hard time detecting the R4DS we have, and requirs us to blow in the slot before it will boot the menu. I have cleaned the contacts of the cart, memory card, and Slot 1 with a Q-tip soaked in anhydrous rubbing alcohol, and the issue has almost, but not completely been resolved. Is there sometimng else I can do to more thoroughly clean Slot 1, while I have better access to it during the shell replacement? 2. The sound form this DS Lite is sometimes staticky, sounding a little like having tuned into an AM radio station with interference. Since I will be handling the speakers and their wires, how do I go about locating the cause of this problem, and how do I fix it?
