The flip screen of my Sony NEX-5 is stuck. It will not slide or flip.

There are a couple of options: Check to see if the camera is turned on. The LCD light might be turned down on the screen. This can be caused by faulty wiring. The screen is not getting power from the device, or the device is not communicating with the screen. The screen itself may be broken as well. Check the troubleshooting page for details.
