Okay, this is what I got going on. Got a DS lite here that from what was talked about, implied that it was the screens. as a measure of total repair, ordered both screens replaced. Finished disassembling and reinstalling the screeens and even got the stupid ribbon cable for the top screen sorted.But now, even after the pain of all that, it still exhibits the same problem. Flick the power switch on. Green light comes on, briefly goes brighter. Top screen flashes and then it completely turns off. Been trying to get this fixed for a friend, and given it's still experiencing the same problem, I'm stumped. And google seems to actively troll me instead of helping me find something to help.
