回复： Why did my radio stop working?Could be various things that cause it to not turn on, but the most likely cause will be a blown fuse. Will have to check for your specific car where the fuse is located for the stereo. There is also a fuse on the rear of the stereo itself on some models so this may be worth a look. Other than that it could simply be a faulty stereo or loose wiring at the back of it. The easiest way to check a fuse without the proper equipment it to pull it out an visually check if you can see a break in the wire in the plastic part between the 2 metal prongs.
回复： iPhone 7 Boot Loop issue with Front Camera/Proximity sensor/Ear Piece FlexNot sure if solved yet, but I had this exact issue, phone will bootloop, but when sensor flex is disconnected it will boot up fine. Strangely enough this was due to a small tear in the flex cable that connects the home button to the board. And when this cable is disconnected the phone boots fine even with sensor flex connected. Hope this helps
