Hello Jose,
First, try doing a soft reset, unplug the soundbar from the outlet for roughly 30 seconds and then plug it back in.
Next, with the Soundbar on, press the + & - (Volume UP/DOWN) buttons on the body at the same time for at least 5 seconds. “INIT OK” appears on the display and then the Soundbar is reset.
If you are still having issues with your Soundbar, please call us at 1-800-SAMSUNG (ask for Soundbars), available 8 AM – 12 AM EST, 7 days a week.
