After putting my DS lite back together (replacing hinges) I now have upper screen problems. It comes on, them immediately goes black. The lower screen works fine. I re-worked it, same problem. Should I try a third time? Please don’t tell me somehow I blew my upper screen.
The main thing that people do by mistake when fitting a new hinge is inadvertently tear the top screen ribbon. This will make the tops screen flash as if its going to come on and then go black - Your DS power light will also flash as this issue will prevent your DS from booting. Things to check - make sure the top screen ribbon is fully inserted into the connector, I know it sounds simple but its an error that lots of people make. If this doesnt work and you cant see a tear in the ribbon either, I’m afraid its a new top screen. Although obviously it’d be a new top screen if the cable has a tear in it. Regards Justin Bayliss
