My kids managed to break the hinge on their one last week. I'm in two minds if I should bother fixing it, new case with hinges is £15 plus time and effort. There are used consoles with accessories going for £30 every now and then.
Do you guys know where you can get new fuses? One of my NDS had a broken hinge, so I replaced the case but one screw made contact to the shield plate of the GBA rom cartridge. Now it powers on en off within one second or so.
