I was trying to set up a DVD-VCR (Samsung VR300) on our Mits 52725 and lost the TV speakers. I have for the life of me tried to go back and put things the way they were before I started, and I can't get the speakers to go on. They are "greyed out" in the area where you turn them on or off. Any body can help, I really want to hear again. Thanks: Lyle
