Hi, Thank you for sharing your experience with the DU7200 TV. There are several volume features you can adjust, which may improve your audio experience. 1) Auto Volume automatically adjusts the sound to a certain level when changing channels or switching to another external input. Go to Settings > All Settings> Sound > Expert Settings > Auto Volume. 2) Adaptive Sound automatically adjusts to a specific volume level while watching TV. The TV analyzes your volume usage history by time period to automatically adjust the volume when you use an app or switch to an external input source. Go to Settings> All Settings> Sound> Sound Mode> Adaptive Sound. 3) Several Sound Modes are likewise available to meet your personal preferences: Home > Settings > All Settings> Sound > Sound Mode. Also, some sources have their own volume control, which might need to be set higher. Please check the volume control of the external device (cable box or satellite box, DVD, Blu-ray, etc.) connected to your TV. Also, check the cable connection between an external device and the TV and then try the cable connection again. If you’re not receiving all channels, first ensure that your coaxial cable is securely connected to the TV. Then, run Reset or Auto Program. • Home > Menu > Settings > All Settings > General & Privacy > Reset • Home > Menu > Settings > All Settings > Broadcasting > Auto Program I hope this helps.

Hi Rail 179, If your TV turns on by itself, please try these troubleshooting steps. 1. Unplug the TV from the wall outlet or surge protector and leave it unplugged for 30 seconds. 2. Check the power cord to see if there is any visible damage. 3. Plug the TV power cord back into the wall outlet. If you were using a surge protector, bypass it for now and use a wall outlet. 4. Try to update the software. In some cases, a software update can correct the problem. There is a risk, however. If the TV turns off during the software update, it could damage the TV. Updates can take up to 30 minutes, depending on network speed, so if the TV is not turning off too frequently, try updating the software. 5. Disable the Power On with Mobile option. TVs that can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on. If you do not want this function, navigate to Settings > All Settings> General > Network > Expert Settings > Power On with Mobile, and turn the setting off. If the TV continues to turn on by itself continuously, please contact our Samsung Customer Support at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
