Don't know what happened. I power on my 3DS XL to download the new update. (because I hear you can make your home screen black now!) So I plug it in, start the update, but a few minutes later I notice the system is off. I power it on, connect to the eshop, it says update available. So the update didn't install successfully? I decide to fully charge the system and try again. So i fully charge it, but when I turn on the system afterwards, a few second later it powers off on its own! Now when i power it on it won't even work. If I tilt the system and squint I can see the home screen. So I guess the backlight is out. However, I notice that pressing the dpad or the screen doesn't do anything. So the system is frozen. There are also bars vertically across the screen. But not anymore. Now when I power on the system I don't see anything, but I can tell the screen is on. Its on but completely black. I don't know what happened to cause this. I didn't do anything to the system recently except switch battery. (I bought a replacement battery from Nintendo) But switching back to the old battery doesn't help. Another possibility is that the weather is getting colder and maybe that had something to do with it. Or maybe I did download the system update and that caused it somehow. Long story short I'm wondering if I should buy a replacement screen. Would that solve the problem?
