I am completely new to all this 3DS stuff, I have previously owned a 3DS when it first came out but I only played games - no downloads no exploring the app store or anything. I've looked at previous posts and don't understand any of the abbreviations for software and these different boot up options. Problem: I bought a New 3DS XL off ebay my mistake being that is was being sold as parts only as it's not booting up. I've had experience repairing handheld consoles but never a 3DS so I'm comfortable taking it apart if need be. When I press the power button the blue light flashes once then nothing happens, no sound occurs nor does the screen turn on. The orange light turns on when I try to charge and nothing happens if I press L + R + A + Up ( D-Pad ) and the power button at the same time. I have tried powering with and without the charger plugged in. Upon taking off the back I've found that there isn't a micro SD in the slot ( No card in the SD slot either ). Are there any possible fixes to this issue ? Should it be able to turn on without a micro SD ? I've ordered a micro SD that should come in a day or 2 if that is the only issue here. Thank you.
