Hello, 2 days ago, my DSi started not starting up. When I press the POWER button, it only shows a white screen and the blue light goes on, but after half a second it goes out again. I don't think it's the battery, because when I start it up while it's on the charger, nothing's diffrent. I have no clue what the cause is . If it's something inside, I can open it. But I don't know what could be wrong and it will void my warranty. So does any of you has any idea what the problem is?
