回答“The DS won't turn on. Green light flashes for a second.”I have got the same problem: Bought a broken DS lite where the top screen’s ribbon cable and the hinge was broken. Bought a new top screen and it didn’t turn on. When I put in the charger (which works fine on my woking DSlite) the orange light flashes, but only at the beginning of putting the charger in. By the time it is properly in there, the light will have already turned of. I read about it on many forums and replaced my F2 fuse, the F1 Fuse has continuity, also tried the LEDA1/2 mehod. Nothing is getting the board to work. The board has no water damage and I use two known goof screens and a known good battery for testing. What could it be?
