I’m sorry to hear that you're having this problem with your Home Theater system.
There are stereo or surround devices, but RCA inputs are typically used for stereo, and optical cables are used for stereo and/or surround signals.
With the limited information that has been provided, I'm unable to assist with troubleshooting. I would definitely recommend contacting the Samsung customer service center, and speaking to one of our chat agents at the following link:http://www.samsung.com/us/support/
Or you can also call them directly at 1-800-SAMSUNG.
We appreciate your support of Samsung products, and we look forward to assisting you.
