sorry but it looks like the ( f1 ) fuse has went on the motherboard and unless your good with a soldering iron to change it it might be best to look at buying a working ds that might have a broken hinge or a broken top top screen for spares and swaping over the motherboard with the bottom screen attached ( as i can`t get a replacement screen to calibrate if i change it over ) and then carefuly put all back together , look up on youtube on how to change a shell etc that should give you ideas
