Hey Guys. I am new to this Forum. I have an issue with my Samsung HT-X40 home theater system. Lately, when I turn it on, it will play for about 45min to an hr and then shut down by itself automatically. Before it shuts down, the screen on the box reads "Protection" and then it goes off. When I turn it back on, no sound will come out. I would have to wait minutes to turn it back on for sound to occur but again it shuts off within 45min to hr. What can cause this? Could this be a Power Surge issue or just my system is defected or something else? Can anybody help me out?
