    (not black), then back to normal, then bright, and so on. Only does
    this when playing a DVD (not when displaying menu items). This was a
    gift from my company, that would be easier to repair or trash than

    start looking for repair? I searched this group and found nothing on
    this particular model. Thankyou as always group.
