Ok... so my DS was working fine, but I had a cracked hinge, so I bought a replacement case. After putting the unit into the new case everything was working fine and I played for about 5 hours when I noticed the light went red meaning I was low on battery. I plugged it up and the charging light did not come on. I tried two cables and had the same issue with both. I left it plugged in and sure enough it powered off, and is not charging. Any thoughts on what I might have damaged in the process of changing my case and is it fixable? edit: this is a DS lite.
