Hey guys, I have a New 3DS XL (2015), just need your advice about something. After messing up the Home button ZIF connector, I installed a new mainboard. Everything works except the 3D Effect, which isn't recognized and won't let me get past the initial 3D Sensor Check even though I slide the 3D slider back and forth. I thought it might be a defective mainboard, but no. I installed my original mainboard and the 3D Effect stopped working there either. So I'm suspecting that one of the upper screen ribbon cables was messed up because of the repeating bending. Do you know which part I should replace? There are only 3 ribbons involved: The top black ribbon for the camera modules, and 2 underneath the main board: the main screen ribbon cable, and the other ribbon cable that connects to the sliders and the speakers (and has some extra 2 tiny ribbons from the screen, which could be related to 3D as well, so that ribbon cable could be the culprit too).
