not a malfunction. They do not aff ect the images recorded.
 If the screen is left on for a prolonged period, screen burn-in may occur
where you see remnants of what was displayed. However, this is only
temporary and will disappear when the camera is left unused for a few
days.

may look black in high temperatures. It will return to normal at room
