I bought a faulty 3DS console and the fault is, "turns on to a black screen". Arrived today and sure enough, turning it on comes up with a black screen (screen lights up but still black). Then I decided to press the button combination to try and get to the recovery screen so that maybe I can at least update the firmware. Still nothing. Then an interesting thing happened. I saw a button combination that allows you to access the touchscreen combination and holy crap, it worked... but if I press the cancel or the home button, it just freezes and hangs. If I can at least reach the touchscreen calibration, is there any hope or salvaging this motherboard?
