Hi George, We're sorry to hear you are experiencing issues with your M70HD TV. If you're not hearing sound from your connected device over HDMI ARC or eARC, here are some steps that can help: 1. Confirm proper port connection. Make sure you're using the HDMI port labeled ARC or eARC on both your TV and the connected device (like a soundbar or receiver). Use a High-Speed HDMI cable with Ethernet (HEC) or Ultra High-Speed HDMI cable to ensure full functionality. 2. Enable HDMI eARC Mode. Go to: Home > left directional key > Settings > All Settings > Sound > Expert Settings > HDMI eARC Mode, and set it to Auto. 3. Enable Anynet+ (HDMI-CEC). ARC and eARC require HDMI-CEC to function. Go to: Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) and set it to On. 4. Adjust Digital Output Audio Format. Some receivers and soundbars may not support all audio formats. Go to: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Format, and set this to Auto if your audio device does not support Dolby Digital+ or other advanced formats. If your device does support higher formats, Pass-Through can be selected to send audio directly without additional processing from the TV. 5. Check TV firmware. Updates may improve compatibility and resolve sound issues. Go to: Settings > Support > Software Update > Update Now to install the latest version. If the issue continues, try restarting both the TV and the audio device, switching HDMI cables, or toggling Anynet+ off and back on.

Hi Stoney, While the M70HD TV Remote may appear minimal, many buttons offer multiple or long-press functions to help simplify the design without sacrificing functionality. For example: • Settings/Number/Color: Allows you to easily access your TV's Quick Settings and input channel numbers. • Volume rocker: Push up/down to adjust volume. Press and release quickly to mute. • Long-press Volume button: Hold for more than 1 second to open Accessibility Shortcuts. • RETURN button: Press to go back to the previous menu or screen. While watching TV, it takes you back to the previous channel. These functions allow for a more streamlined experience without adding extra buttons. Learn TV Remote is a feature designed to help users become familiar with the layout and function of each button on the Samsung remote. When enabled, pressing any button (except the Power button, which will still turn off the TV) will prompt the TV to announce the button’s name and its purpose – without affecting TV operation. This teaching mode is especially useful for users who are visually impaired or new to Samsung remotes. To enable this feature, go to: Settings > All Settings > General & Privacy > Accessibility > Learn TV Remote. To exit, simply press the Return key twice. If you’d like more assistance with this feature, please reach Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
