The panel is seated on a positioning apparatus which allows the panel to be adjusted such that the defect to be removed is centered on cross-hairs located on the monitor. The support structure includes a second rail member to which is mounted a laser apparatus which produces a beam of laser energy to remove the defect from the grille.
