Hello Marie,<br /><br />Thank you for sharing your experiences with the HW-C400 Soundbar. I am sorry to see that you are not fully satisfied with your purchase. <br /><br />There are a few steps you can take to troubleshoot your Soundbar. <br /><br />Please verify that you are running the latest firmware on your Soundbar. You can download the firmware directly from Samsung’s website by clicking “Support” in the top right corner. Then go to “Manuals &amp; Software” &gt; “TVs &amp; Home Theater” &gt; “Home Theater” &gt; “Sound Bars”. From there, you can select the HW-C400 under Standard. <br /><br />Next, try doing a soft reset, unplug the soundbar from the outlet for roughly 30 seconds and then plug it back in. <br /><br />If this still does not correct your issue, then do a hard reset. With the Soundbar on, press the &#43; &amp; - Volume buttons on the body of the soundbar at the same time for at least 5 seconds, then the Soundbar will be reset.<br /><br />If your soundbar is connected to your TV with an optical cable, you can control the volume and mute the soundbar using your TV&#39;s remote.<br /><br />1) Use the TV remote to navigate to Settings, select Sound, and then select Sound Output on your TV.<br />2) Select your Samsung soundbar, and then select Close. Now you can use your TV remote to adjust volume and mute the soundbar. The soundbar should also turn on and off with the TV.<br /><br />Other manufacturers’ remotes may have to be enabled on your soundbar. First, turn Off the Soundbar. Once powered off, push up and hold the WOOFER button for 5 seconds. Each time you push the WOOFER button up and hold it for 5 seconds, the mode switches in the following order: “OFF-TV REMOTE” (Default mode), “SAMSUNG-TV REMOTE”, “ALL-TV REMOTE”. Please also make sure your speaker settings on the TV are set to External Speaker.<br /><br />You can refer to this article for further details: https://www.samsung.com/us/support/answer/ANS00049279/<br /><br />If we can help with anything else, please call us at 1-800-SAMSUNG (Ask for Soundbars), 8 AM – 12 AM EST, 7 days a week.

Hello Cristie,<br /><br />I’m very sorry for the difficulties you’ve experienced with your Soundbar’s setup. We completely understand your frustrations, and we are here to help.<br /><br />The HW-C400 features two ways to connect to a TV; digital optical audio and Bluetooth wireless audio technology. If your TV is compatible with one of these two audio connections, you should have no issue connecting the soundbar to your TV. Follow the steps below to connect the soundbar to your TV via one of the two available connections:<br /><br />An optical cable is a great way to connect your soundbar to your TV and the method we recommend using for the HW-C400. With optical, you can also connect your devices (cable boxes, video game systems, and Blu-ray players) to the TV, and have the sound output from the TV to the soundbar.<br />1. With the TV and soundbar turned on, connect one end of a digital optical cable to the OPTICAL OUT port on the TV.<br />2. Then, connect the other end to the DIGITAL AUDIO IN (OPTICAL) port on the soundbar.<br />3. Press Source on the remote or soundbar, and then set the soundbar to the D.IN. setting.<br />4. Finally, on the TV, you need to set the speaker output to external speakers.<br /><br />The TV&#39;s sound will now play from the soundbar.<br /><br />Your soundbar is also compatible with a Bluetooth connection to the TV. To connect the soundbar wirelessly, follow the steps below:<br /><br />1) Press the PAIR button on the remote to enter BT PAIRING mode. You can also press the SOURCE button on the top panel and then select BT. “BT” changes to “BT PAIRING” in a few seconds automatically or changes to “BT READY” if there is a connect record. If BT READY appears, press and hold the SOURCE button on the top panel of the Soundbar for more than 5 seconds to display BT PAIRING.<br />2) Select the Bluetooth sound mode on your TV (See your TV&#39;s user manual for assistance)<br />3) Select “[AV] Samsung Soundbar C400 Series” from the list on the TV’s screen. An available Soundbar is indicated with “Need Pairing” or “Paired” on the TV’s Bluetooth device list. To connect the TV to the Soundbar, select the message, and then establish a connection. <br />When the TV is connected, [TV Name] → “BT” appears on the Soundbar’s front display. <br /><br />You should now hear TV sound from the Soundbar. Once you have connected your soundbar for the first time, use the “BT READY” mode to reconnect.<br /><br />If you need more help, Samsung is here for you.
