I'm thinking about putting together a DS since I don't have one. I have some spare parts from other DS's that I have except for a new housing. But I have a problem which I'm not sure. I have 2 DS motherboards and some screens. I'm not sure if they work as I know that once I turn on the DS, the bottom screen would be messed up (black spots in the corner) and then the DS would turn off. I know that probably means that the bottom screen is broken and I may need a new one but if the DS turns off, does that mean the motherboard is broken beyond repair? Or maybe it is just the screens?
