How do I connect a Samsung soundbar to my Luxor tv

[Catherine_11]

The soundbar has only a sun connector at the back

Without model number we can't be specific. Don't know what you mean by 'sun connector' either
Info on Luxor TVs is sparse and I can't find any mention of audio output other than bluetooth so you may need a soundbar that connects with bluetooth. If the Samsung doesn't you would need a bluetooth receiver that could connect to an aux input.
