It is possible, but it is held down by adhesive, and its actually a plastic screen lens, so it scratches easily. I’ve seen people heat it up with a hairdryer, but I would use ifixit’s Iopener thing. It is used in the same way as you would for replacing the lcd for an ipad generation 5 lcd. (look at their guide for that, and maybe try the same tools and technique for this.) Just be incredibly careful.
I read online that the speaker flex cable is fed through the hinge, and repeatedly opening and closing it may break it. If you close your 3ds so you can barely see the screen you may be able to turn it on and see a display. (didn’t work like that for me.) They say to just replace the Speaker Flex Cable. It is what makes the popping noise, because it is soldered to the speakers, and it plugs into the top screen, which is why it works this way.
I once had this problem, and what fixed it for me was leaving it on, to let the battery slowly die. Once dead recharge it, and it rebooted like normal for me.
Go to settings, and you should find buttons for calibrating the screen using a stylus, and one for calibrating the circle pad, the circle pad is the one you want. it should be somewhere near where date and time is. If the stick moves on its own (the physical part, then I recommend opening it using an ifixit guide, and looking at the circle pad to see if it is dirty, and if it is, then take it out and clean it.
I haven’t Had time to Attempt it, but if I get the time, I will reply to this thread weather it worked or not.
