Color problem with PH Photosmart R717 camera

[wellnessyoga]

I have a hp photosmart R717. It is an old camera, but I love the quality of pictures it takes. Or used to take until it started displaying mostly green colors. Most pictures show a predominant green, the odd picture may be more normal. Used to be that just one or two pictures were green, but now it has gotten way worse. Is there something I need to reset or a part I need to replace? Or would it be best cost wide to get another camera?
Thanks!

I've seen low battery cause odd coloring. If it's not the battery, it's probably not worth fixing over getting a newer camera.
