The camera lcd screen on the back is displaying weird colours and distorted pictures. When a photo is taken the image is very weird in colours and horizontal lines when displayed on the CD (not matching what was shown in viewfinder when taken) and the photo itself on the computer is also distorted. Lens is OK.Have checked all menu settings and butons, reset CF card, but still no luckANY IDEAS?CheersDavid
