In short this sounds like a failed sensor. It is a common issue across many makes and you can find a lot of discussions about it.
As above, you should always call it in and see if they'll stand up and replace the defective camera.
hello I have a samsung es55 digital camera and there's lines running through the screen. the camera quality isn't excellent and has a purple tint to it is there anyway I can reboot it or improve the quality of the screen? thank you
The purple sensor issue is well known. If someone doesn't respond they know and wants to look and they don't try a full reset then they may be out for a service call and money.
Here in the USA it's a toll free call to 1800SAMSUNG and you have the CNET Samsung forum you can try as well.
