Hello, I'm Shahid. Sorry to hear that you're having trouble with this but I'll do my best to help.
- Can you please get me the model number off of sound system?This info will help me to see the options.
I understand, amplifier should have Digital Audio Input port to plug optical cable for sound signal as TV has Digital Audio Out port at rear that provides digital format audio signal through optical cable, if your amplifier doesn't have such input then you would need to use 'digital audio to analog audio converter device' between TV and amplifier. Please click following link to view converter device..
This device will get digital audio signals from TV through optical cable, converts it into analog audio signals that can be connected to amplifier through RCA type audio cable. I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
