Solved! HELP, how do I connect old dvd home cinema with scart to new smart tv without scart.

Sep 28, 2020
I have an old LG home cinema system (LH-T550) which I have always connected to my tv’s via scart And this worked really well. I have now purchased a new smart tv (Toshiba 55VL5A63DB) which doesn’t have a scart connection. I tried a scart to triple rca adaptor but have been unable to get any tv sound through the surround sound speakers. I’ve tried altering tv settings etc but just can’t get anything to work - have I done something wrong? Or would there be a better / easier way to make the connection. I’m not too tech savvy so please don’t make replies complicated. Thanks in advance.
