Based on the information you've provided it seems that the CCD
Image Sensor of the Camera is affected which displays the live view of the Camera and the image which get captured. If the Image Sensor is affected, the previous views of the images and the icons will get displayed as normally, but the live view and the captured images will be distorted or blacked out. You may try power resetting to check if the issue can be resolved.
Performing a manual power reset
Turn off the camera.
Remove the battery pack.
Press and hold the power button for 30 seconds.
Allow the camera to remain without power for 60 seconds.
Reinsert the battery pack.
Turn on the camera.
If the issue persists, service may be required.
