Why is is the LCD screen freezing?

Firstly, restart the camera by pressing the power button and leaving it off for ten seconds before powering the camera back on. If the camera feels hot, make sure that it's not overheating and give it adequate time to cool down before continuing to take pictures. Lastly, open the battery cover and remove the four AA batteries for ten seconds and reinsert them. If the camera continues to freeze, contact the manufacturer to see what can be done.
