Back like in 2011-2012, my DSi XL rejected to turn on. But i dont know why did that happen. They also repaired me the DSi XL, but it ended losing microphone data. Is there a way to repair the microphone?
Nintendo DSi XL Microphone Replacement There is the iFixit guide for the microphone but I would place my money on it just being unplugged. Good luck.
