I just bought a 40" dynex TV and Samsung HT-C550 5.1 system.
So I have my cable box and PS3 hooked up to my TV with HDMI cables and then my TV hooked up into the Samsung dvd player/reciever via an optical audio cable.
I set everything up but only the two front speakers work on anything, TV, games, blue-ray, the rear and center speakers are doing nothing.
What's going on?!?
