Hi, Since a few months now my ds (old grey DS) top screen didn't work properly, it tended to go white or freeze, and I had to move it a bit to make it work. Obviously bothering in many games. I opened it and check the ribbon, rubbed it very lightly with cotton and a drop of medicinal alcool to clean it (it was kinda dusty). I realized there was a small scratch on the ribbon, but apart from that, it looks fine. And after putting everything back in place, it doesn't work. The green light comes on... the bottom screen light flashes white for a split second... then it shuts off. I don't think it's the battery because the light flashes green, and if i plug it, the orange light turns on and it seems it's charging. Anything I could do to put it back to work?
