I bought a broken DS phat so I could fix it. The touch screen didn't work when I got it (it wasn't broken, it just wouldn't respond, it wasn't plugged in right), but I managed to get it to work, however when I click the back-light button or touch it with my stylus the light won't come on. Could the connector be broken or it it possible that the cable might be fryed? Input would be nice. I also have a dsl that when I turn it on the screen turns pink and the top screen turns a dark gray. Is it possible that the fuses are bad?
