There can be many reasons why your camera is not displaying images. One of the simplest problems is that your camera does not have a memory card. If your camera does not have an outer memory card, you can purchase one online or at your local electronics store. Another problem might be a faulty screen. If this is the case, you will have to replace the screen.
Another option is to is to check and see if there is any problems with your motherboard. Sometimes a small issue with the camera motherboard can cause the screen to only show certain things such as, the menu.
Another solution to take into consideration is checking the camera lens. If any of these solutions do not work, then your best option is to replace the camera or reset the camera to factory settings.
