as stated in the title, my 3ds won't turn on, the power light goes on, stays blue and doesn't shut off like it would if it was dead, the screens and sounds don't go in though.
Just an idea: try holding down the L and R triggers and either Y or X when you press the power button. That should take you to the "calibrate circle pad" or "calibrate touch screen" option, respectively. I'm just curious to see if that works.
Today I dropped my 3DS onto the concrete floor in my garage on accident. I was getting worried because I was experiencing the same issues. I would try to power it on and the blue light would go on although both screens stayed blank. I had to hold in the power button for 10+ seconds in order to power it off. The charging light also worked.
However, I don't know if it was coincidence or not, but I tried holding L + R when booting and.... IT WORKED. It didn't bring me to any calibration menu or anything but brought me to the home menu, fully functional. Now my 3DS seems to be back in working order.
Anyone with this problem - try this guy's advice. It may have been a miracle but it worked for me !!!
Didn't work for me. :/
That is unfortunate, as it may mean your 3DS may need to be repaired, sorry.
So give a call to Nintendo's 1-800-255-3700 (6 am ~ 7 pm Pacific, everyday) Customer Service number, or use their webform to contact them, and they can set up the repair process for you.
