Hi and welcome!
Without examples, it's hard for us to judge. Does this effect what you see through the viewfinder, the LCD, and/or the resultant recorded image. If it is the latter, then your sensor is likely kaput and that will not be serviceable.
If you want a similar kind of camera, then go to the Canon Sales site and browse through the selection there.
cheers, TREVOR
