I took apart my little boy's ds to clean all the crap out of the buttons and when I put it back together it wont power up. the green power light comes on, gets just a bit brighter and then the touchscreen flashes and the system shuts off. I've taken it apart dozens times before so I don't know whats different. Just to see if I had a screw in the wrong place or something I bought my little girl the pink ds and took it apart only to have the EXACT same results when putting it back together? I returned it and she got a new one but I still can't get my boys working? Has anybody seen this before?
