I noted a faint line on the screen about 5" long. I examined it and could see it swaying a little as if it were part of a spider web, swaying with the air current. It is not bothersome but a bit annoying. It is sharp, not blurred, so I believe it is on the inside surface of the screen.
Does anyone have any thoughts about removing it (short of taking off the screen)? I am considering a compressed air (aerosol) can using one of the cooling air exits for access.
