So a while ago my 2ds xl’s screen snapped (upper) and it did what i am still experiencing today. I know for a fact that my upper screen flex cable was torn so i removed it, as well as the WiFi antenna. I tried isolating every cable and flex cable, but to no avail. I finally trying turning on the system with out anything connected, just the motherboard, and it still does the same thing (but of course with out the pop). Is there a way to fix this?
I’m pretty sure the 2ds xl will refuse to boot if the top screen ribbon cable is damaged or disconnected. Your best shot is probably to replace that cable and reconnect everything you took off
