I disassembled a regular DS for my kid brother, so that I could replace the shell with a black one he bought off of eBay. I get the thing to turn on and all seems fine except the top screen is white with out anything else. Now I know enough to asume its the video cable that travels from the top screen to the mobo. My question is: is there anything else it could be or a way I could test to see if its the cable? BTW the only trouble I had with the cable was when I had to run it through from the top to the bottom, but the cable is not cut or damaged from what I can see.
