I recently got a 3DS XL… With a broken hinge (clicker, diffuser, middle casing). Everything was working… except for the cameras. Going into the L or R camera mode brought up the application, but the camera preview was black. Switching to inner camera froze the application, and attempting to go "Home" caused the 3DS to hang on the "Home" banner. The pink top camera light didn't shine, either. Oddly, the preview would show up for the QR code function, and I was able to scan the codes normally. Since it was on firmware 8.1, I downgraded to 4.2. Nothing changed, it still acts the same way… Fixing the hinge didn't seem to change anything, either I tried to import a pattern in Animal Crossing by scanning a QR code, and the preview was black again… After trying a few times, the preview was a weird green pattern, But the 3DS LR camera QR code function worked just fine. Anybody here have experience with these issues? Alternatively, does anybody have experience replaced the camera? I know there are camera modules on eBay and such… but I can't seem to find any replacement tutorials/guides. It's a pity, most answers to 3DS hardware issues are "send it to Nintendo"… Why isn't there a larger repairing community?
