My 3DS top screen goes dark, bad flex cable maybe?

I've had my 3DS for a few months now, recently the top screen starts going dark, I can usually wiggle it to get it back, its like the backlight goes out or something. I don't know if it the device has been dropped, my 3 year old plays with the device quite often so it is possible. Other than that the device works fine. When I started googling similar problems I found some people talking about the flex cable, I guess it can go bad from just opening and closing the screen on certain models. Anyone encountered this problem or any clue on how I can fix it. My son ripped the serial number sticker off the back of the device so I can't send it back to Nintendo to get fixed. If its something I can fix myself I'd like to that anyway.
