I recently bought a Samsung NV10 and have been having trouble when taking pictures especially during the day. When taking pictures one minute the pictures are fine and the next minute there appears to be horizontal white lines across the screen. This happens no matter what mode I'm in. Also when taking pictures if its bright, the picture just appears as a mass of white light. I'm quite inexperienced when it comes to photography and hopefully I am just making basic errors, however any help would be greatly appreciated.
