My screen is purple and looks like mountains no

Sounds like this thing has gotten moister n it or the LCD is damaged ether way you must replace the LCD screen and that is going to cost a big $75-$80 upwards depending on where you take it to. if you can deal with it lik it is until the camera decides not to work anymore you might be better off but if you cannot well ether shop for a new camera or foot the bill. I hate telling people bad news but have to daily but I hope it does not effect how you rate me :)
