I have had this issue for the past week or so, and I do not know what's wrong with my DS. I turn on the on / off switch, and the green LED turns on but the screens and sound are unresponsive. So I Google'd the issue, and the results all tell me something like a piece fell off and they just had to solder it back on. I ordered a screwdriver to open it up, and yesterday I get to dissembling it. However, I found that there were no pieces broken off or even loose pieces. I compared it to a DS Lite circuit board picture and everything seemed normal. I disconnected the two wires and reconnect them just in case, then I reassemble my DS. However my DS still does not turn on. Any suggestions on what it might be specifically? ~ This may be in the wrong forum. Move it if necessary.
