If LCD screen has gone white or blank, it means you cannot see any error message and you have to reset your Samsung digital camera.
- Switch OFF your camera
- Remove battery and memory card from it and leave your camera like that for about 15-20 minutes
- Now clean the dust from the battery compartment and also make sure that battery’s metal connections are clean
- Now re-insert the memory card and battery and turn ON the camera
I hope your problem will be solved, if not then your camera may need repair.
