My New 3DS XL almost gave me a heart attack. I turned it on, the power light was blue and the wi-fi light turned on, but nothing appeared on screen. I tried waiting, but nothing. I dunno why, but I had the idea of opening it, taking the battery off, putting it on again and turn it on to see if it had any effect, and to my good surprise it worked, it's now working fine, at least for now. Have any of you experienced this?
