I’ve looked through all the threads and can’t find anything so, I figured I’d ask. I have a 2016 Lg tv model # 65UH6030 with a rca 2010 model #rtb1023 blue ray surround sound. I can get the speakers to work with dvds but not with the tvs like everyone else but I have the HDMI plugged into Arc port still nothing. I tried the red and white rca jacks still nothing I tried changing the mode on my tv audio out still nothing so if anyone had some advise I’d appreciate it!
 
You have an optical digital output on your TV. This is what you want to use to feed into your RCA. If your RCA doesn't have digital optical in, you need a converter.
 

Could you send me the link to what I need please? My tv does have the optical digital audio out. But the blue ray player does not.
