DS lite flashes then shuts off
I am fixing a friend's Nintendo DS lite. The top half is nearly separated from the rest, only the two black/grey cables are holding it in place. The screen cable is torn. I am sure I will need to buy new hinges.
When I try to turn it on, the power light turns green and the bottom half flashes white for a fraction of a second. Is there more wrong with it then the top screen and hinges? Do I need a new shell as well to replace the hinges?
I am not familiar with DSs, so excuse my ignorance.
Thanks for all your help!
