Why is the screen not working?

"The reasons why the screen would not be working could be because the camera is having issues initializing everything properly, or the LCD screen is either damaged inside or is not properly attached to the rest of the camera's circuitry.

If it is because of an initialization issue, there is a simple solution which is to reset the camera to manufacturer or original factory settings. In order to do it with this model, you will need to access the Initialize or Reset option through the camera menu. Follow this path: MENU → Settings → Main Settings → Initialize → OK.

Prior to following these steps, make sure to not turn the power off while resetting is in progress. Be aware that this model supports the PlayMemories™ Camera Apps and in resetting, apps downloaded may be uninstalled. To use them again, reinstalling will be necessary. However, all movies and photos will be retained. If an error code starting with a C: or E: is displayed on the screen resetting may not resolve the problem.

If the LCD screen is damaged or not properly attached, the solution will be to replace the LCD screen or properly reattach the screen band to the rest of the camera. In order to do either, you will have to open up the camera. You can use the LCD Replacement Guide and follow the instructions to fix these issues:
