I have a 3DSXL that when power is pressed the power light comes on blue but the screens do not power on at all. No backlight on a black screen or anything. The Wifi Light is not on and holding the power button down for 10 seconds still works to turn the system off. I replaced the top screen and this is the state the system was in after the screen was replaced. Prior to this the bottom screen worked and wifi was working. My question is if I messed up when replacing the top screen wouldn't the bottom screen still work or at least the WiFi still show active? Any help in how to fix this issue would be amazing thank you for your help.
