Hello Mike197, Thank you for taking a moment to review the HW-Q990D Soundbar. There are a few steps you can take to troubleshoot your Soundbar. First, you will want to download the latest software for your Soundbar. You can download the firmware directly from Samsung’s website by clicking “Support” in the top right corner. Then go to “Manuals & Software” > “TVs & Home Audio” > “Home Audio” > “Sound Bars”. From there, you can select the HW-Q990D under Q Series. Download the update and install it via USB thumb stick to your soundbar. If you need additional help, there are how-to instructions on this page. Please know that Samsung Customer Service is here to assist as well. Alternatively, you can download SmartThings on your iOS or Android device. This will allow you to update your Soundbar automatically or manually right from your phone or tablet. Please verify that you are running the latest firmware on your TV. You can check to see what software version your TV is using and if there is an available update through the settings on your TV. Go to: Menu > Settings > Support > Software Update. First, try doing a soft reset, unplug the soundbar from the outlet for roughly 30 seconds and then plug it back in. If this still does not correct your issue, then do a hard reset. With the Soundbar on, press the + & - Volume buttons on the body of the soundbar at the same time for at least 5 seconds. INIT OK” appears on the display and then the Soundbar is reset. While the Soundbar is On, press both the Vol+ and Vol- buttons on the unit simultaneously until the display shows "INIT", then release. If this doesn’t work, then try using the remote control: While the Soundbar is ON, press and hold the SOUND CONTROL ("Gear") button on the Soundbar remote for 10 seconds. You will see "150HZ" on the display. Keep pressing until you see "INIT" on the display, then release. If you need more help, Samsung is here for you. Please call us at 1-800-SAMSUNG, 8AM - 12AM EST (Ask for Soundbars), 7 days a week. Live Chat with an agent as well as manuals, software, creating a service ticket, and warranty info can be found at the ‘Support’ link on our Samsung website. ~ Samsung Solutions

Hi SamsungUs3r, We appreciate you taking a few moments to review the HW-Q990D Samsung Soundbar. You can manually optimize your audio experience by pressing the SOUND CONTROL button (which looks like a gear), you can set the audio function such as Auto EQ, Spacefit sound, AVA, Voice Enhance mode, Night mode, Sync, Surround speaker mode, Virtual. The desired item can be adjusted using the Up/Down buttons. Alternatively, you can press and hold the SOUND CONTROL button for about 5 seconds to adjust the sound for each frequency band. 150Hz, 300Hz, 600Hz, 1.2kHz, 2.5kHz, 5kHz, and 10kHz are selectable using the Left/Right buttons and each can be adjusted to a setting between -6 to +6 using the Up/Down buttons. You can try quickly optimizing the audio by pressing the SOUND MODE button on your remote, and then select the desired sound effect by choosing STANDARD, SURROUND SOUND, GAME, or ADAPTIVE SOUND. To control the volume of each speaker, press the CH LEVEL button on the provided remote. Then select CENTER LEVEL, SIDE LEVEL, WIDE LEVEL, FRONT TOP LEVEL, REAR LEVEL, or REAR TOP LEVEL. Once you find the channel you are looking for, adjust the volume between -6 to +6 by using the Up/Down buttons. There are multiple ways to control the bass levels for your new Soundbar. 1) Using the WOOFER button on the provided Soundbar remote. Use the woofer button by pushing forward or pulling backward on the button itself to adjust the bass levels between -12 or -6/+6. If you want to reset the bass to 0 then push the button in. 2) When you press the TONE CONTROL button, you can adjust the treble or bass levels between -6/+6. Alternatively, you can adjust all of these same settings and more within the SmartThings app. Download the app for your iOS or Android device and then connect your Soundbar to Wi-Fi. From here, you will be able to adjust all of the same settings as the provided remote, but with the added benefit of being able to see the changes on your smart device. I hope these tips help you enjoy your new product. You can always contact us for further help at 1-800-SAMSUNG (Ask for Soundbars), 8 AM – 12 AM EST, 7 days a week.
