Do the lines follow the same vertical pixel width from top to bottom or do they cross pixels? first try going into the menu and select auto-adjust. it just might be out of sync. you can adjust the resolution as well. if nothing changes, you might have a bad dmd (digital micromirror device). if that's the case and the projector is pretty old, replace the projector.
