Hi Cybdiver, Thank you for your feedback. Please know your opinion is important to us and will be shared with our internal teams. Regarding audio issues, 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. To select a channel on your TV, press the 123/Settings button on your remote. Then select the number keypad and enter the channel number. The Bluetooth in the DU7200 TV is up to date and should connect to your external Bluetooth devices. If you need more help, Samsung is here for you!

Hi Did not work, We appreciate your feedback on the Samsung DU7200 TV. I'm sorry to hear you are experiencing issues with your Wi-Fi disconnecting from the TV. 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. I hope these tips help resolve your concerns.

Hi Andreas, We appreciate you sharing your experience regarding an unusual sound coming from your TV. The cause may vary depending on where the sound is coming from and how your system is set up. • If the sound is coming from your TV speakers, or if you're using an external audio device like a soundbar, please double-check that the audio cable is securely connected to the correct audio output on the external device. • If you're using an antenna or cable connection, a weak signal may result in sound distortion. You can check your broadcast signal level by going to: Settings > Support > Device Care > Self Diagnosis > Broadcast Signal • If the sound seems to come from the back of the TV, it may be the result of thermal expansion or contraction of the outer casing. This can cause a soft popping noise and is considered normal - it does not indicate a malfunction, and your TV remains safe to use. We also recommend running a Sound Test to check for audio issues: Home > left directional key > Settings > Support > Device Care > Self Diagnosis > Sound Test If the issue continues or you’d like assistance, feel free to contact Samsung Support at 1-800-SAMSUNG, available from 8AM - 12AM EST, seven days a week.
