Horizontal Lines Thru Picture on R967 Camera

Does anyone know of a fix washed out pictures with horizontal lines thru them. Pictures taken outside are washed out with the lines included while flash pictures seem OK but the lines, although weak, are still there.
It was OK prior to a flight. I took the camera thru the check in and when I tried it after that, the above condition was happening.
HP techs say it's a fault in the shutter letting light in and they will give me some credit on a replacement (It's about a year out of warranty).
