Today I had decided to play my 3DS again for some nostalgia. It's been a while since I last played it, a few months. When I tried turning it on, the 3DS blue light would light up for a second and fade out without a sound. It would keep doing this as long as I have the SD Card inserted. When the SD Card is not inserted, the 3DS would stay on, but on a black screen. I do have CFW, I believe Luma 9.1, and I have a New Nintendo 3DS XL. Something worth noting, I have had a problem with this 3DS before, where the same thing would happen because somehow my SD Card slot was loose and it did not properly read. But seeing as though removing the SD Card keeps the system on must mean that this is not the cause again, but something different. I've been following this thread for some insight, and I still have not been able to fix my 3DS. Are there any more things I should try?
