Have TV Questions? Ask a TV Technician
Hello and thank you for your question Judy. I'm a Home Theater Integrator and will be glad to help you.
Your TV uses an "Optical" port to send sound out to external soundbar systems. This is labeled "Optical Audio Out" (or Digital Audio Out). So any soundbar that has the optical input port will work (which most- but the most inexpensive ones use).
I'm not sure what your budget for a soundbar is- but I'm pulling up several recommendations right now.

Finally, if you're an avid listener and want stellar sound quality, I would recommend the Samsung below for $500:
