TV Repair Questions? Ask a TV Technician for Answers ASAP
I am reviewing your details and will reply shortly.
First, the Samsung has no analogue audio outs (which is likely why you're not getting any sound). Those red and white jacks on the TV are for INPUT ONLY- and do not send audio out to external devices. This TV uses an optical jack (the connection is called "digital audio out") and requires a converter to connect to your Sony system. I'm pulling up the link to that device now.
The device needed is below, and you will also need to purchase an optical cable from Amazon as well:
The converter will connect to the TV using an optical cable, and then the Sony can be connected to the converter using red and white RCA type cables.
