Hi Mich, Thank you for sharing your experience with us. We recommend you try a Sound Test under Support > Self Diagnosis > Start Sound Test. Another way to check the source volume is to test an internal streaming source like Netflix or YouTube to compare. If you are hearing a loud static noise, it could be caused by electrical feedback. I recommend the following: 1. Arranging the cables and making sure the TV has good ventilation will keep it quiet. 2. Check the cables. Make sure all cables are connected firmly to the proper, color-coded inputs on the TV and on the external devices. 3. Replace the audio connection cable. Replace the audio connection cable, even if it is an HDMI or RF coaxial cable. Then test again to see if the issue still occurs. 4. Try connecting a different external device to the same input on the TV. Connect a different device to the same input on the TV using the same connection cables. For example, if a cable box is connected using the component connections, try connecting a DVD player to the same input with the same cables. If there is no buzzing, crackling, or humming with the second external device connected, the original device (the cable box in this example) is the source of the noise.

Hi Tams, Thank you for reaching out to us about the issues you are experiencing. Please try the below troubleshooting steps: First, let's ensure you are running the latest Firmware. Go to Settings> Support> Software Update. I recommend enabling auto-updates to ensure you do not miss any Firmware Updates. Go to Settings> Support> Software Update> then select Auto Update. Next, let's try running a cold boot on your TV. To do so, hold down the Power button on the Samsung TV remote until the TV turns off and then on again. This should take about 5 seconds. Finally, please ensure that your TV is in Home Mode by going to Settings> All Settings >General & Privacy System> Manager Usage Mode> Home Mode. If you continue to have issues, please give us a call at 1-800-SAMSUNG, 8 AM – 12 AM EST, seven days a week, or Chat with us on Samsung.com: https://www.samsung.com/us/support/contact/ ~Samsung Advisor
