New 3DS won't turn on

My New 3DS will not turn on, clicking the power button doesn’t turn it on but after a dozen presses it the power LED will flash red for a second and immediately fade away. If the 3ds is plugged in the charging LED will turn on but hitting the power button does the same as before. I have tried replacing the battery but the issue is still the same. Please help if you can, any help is helpful :>
