Fuji Z10FD Problem

[torapoole]

Hi everyone
Just wondering if anyone here can help me- I have had a Fuji Z10FD for 18 months and recently it has been taking photos with a pinky hue and lines down the photo. It only does this intermittently- other times it works fine! Does anyone have any idea what is wrong, and if it would cost much to fix? If it's not worth my while and I have to buy a new one, would I get much for the faulty camera?
Here is a link to an example of a faulty photo I took with it: http://i47.photobucket.com/albums/f1...e/DSCF2698.jpg

Many thanks in advance!!
