Hi Sam Stephens, Thank you for your feedback. We’re sorry to hear you experienced difficulty mounting your TV. The mounting holes are designed for VESA-compatible hardware, and the threaded inserts may be recessed within the openings. For the 55” M70HD, the required hardware is 4x M8 screws with a 1.25mm thread pitch and a recommended length of 23–25mm. Compatible screws can typically be found at most hardware stores. Please note that the necessary screw length may vary depending on the thickness of your wall mount bracket and whether spacers or washers are being used. We recommend confirming the correct mounting hardware is being used, as an incorrect screw size or length may prevent the screws from properly engaging with the threaded inserts. If you’ve confirmed the correct hardware and are still unable to securely install your mount, please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents are also available via the ‘Support’ link on our website. ~ Samsung Advisor

Hi Marty5223, Thank you for sharing your review. Your TV Works With Alexa, meaning you’ll need to connect a standalone Alexa device such as an Echo speaker, to control compatible smart home devices and some experiences on your TV. Here are the steps: 1. Download both the Amazon Alexa and Samsung SmartThings apps, if you don't already have them. Both are available for iOS or Android devices. 2. Make sure your Alexa device and TV are both connected to the same Wi-Fi network. 3. Your TV must be enabled within the SmartThings app. If not, make sure you are signed in with your Samsung account on the TV: Settings > All Settings > Samsung Account 4. Log in to the SmartThings app with the same Samsung account. Tap Devices, and if your TV isn’t already shown, tap + to add it to the app. 5. In the Alexa app, enable the SmartThings skill and sign into your Samsung account. This will automatically connect your Samsung TV to Alexa and let you use voice commands to control your television. If you need more help, we’re here. Give us a call at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). You can also connect with a LiveChat agent through the Support link on our website. ~ Samsung Advisor

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. If you need further help, please reach out to Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
