Hi SB52, We appreciate your feedback on the M70HD TV. For optimal performance, please ensure your TV is running the latest firmware. You can check this by going to: Home > left directional key > Settings > Support > Software Update To further optimize performance, try running Device Care, which checks memory, clears unused cached data, and closes background apps: Home > left directional key > Settings > Support > Device Care > Start Device Care. Please know that although your TV does not have a built-in voice assistant, it does work 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. You can also use the Samsung SmartThings app on your mobile device to set up a daily routine, such as turning off the TV at a certain time each night. To set up a routine, please follow the below instructions: Step 1. On your phone, navigate to and open the SmartThings app. Tap the Home icon and select the location with the device you want to use in the Routine. Step 2. Tap Add (the plus sign), and then tap Routine. Step 3. Tap + under "If" to set your desired conditions for the routine, such as the time it will trigger. After tapping +, follow the on-screen instructions for your chosen condition. Step 4. Tap + under "Then" to add an action to the routine. If needed, you can assign an offline device to an routine. If the device says (Offline) next to it, you can still select it and then choose your desired action. Step 5. Read the on-screen instructions to finish the setup, and then tap Save. Step 6. Assign a name to the routine, and then tap OK. When the conditions are met, the device will automatically perform that action! We hope these tips are helpful. If you need any further assistance, please don’t hesitate to call us at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun), or reach us via text anytime.

Hi Mark, Thanks for sharing your experience with your screen displaying a black screen and “No Signal” message. This typically indicates a connection or source issue. Let’s walk through a few steps to help get things working again. 1. Check Source & Connections • Confirm the source: Use the remote to make sure the TV is set to the correct input. Go to: Home > Left directional key > Connected Devices > Sources • Verify connections: Ensure all external devices (like a cable box or Blu-ray player) are powered on and securely connected via HDMI. Try switching to a different HDMI port or using another cable to rule out a faulty connection. For best results, use a High Speed HDMI cable with Ethernet (HEAC) – this supports stable 4K video and audio signals for most external devices. • Using a soundbar or A/V receiver? If you're connected through the TV’s HDMI eARC port, be sure to use a certified Ultra High Speed HDMI cable to enable lossless audio formats like Dolby Atmos and maintain proper eARC functionality. • Power cycle the TV: Unplug it from the wall for at least 60 seconds, then plug it back in. 2. Update Your TV Software • Make sure your TV is running the latest firmware: Home > Left directional key > Settings > Support > Software Update 3. Signal & Broadcast Checks (Especially important if you're using a cable box or antenna.) • Check signal strength: Home > Left directional key > Settings > Support > Device Care > Self Diagnosis > Broadcast Signal • Run Auto Program: Home > Left directional key > Settings > All Settings > General & Privacy > Broadcasting > Auto Program 4. Advanced Troubleshooting • HDMI Test: Home > Left directional key > Settings > Support > Device Care > Self Diagnosis > HDMI Test • Try a different device: Connect another external device to the same port to help identify whether the issue lies with the original device or the TV. • Check the power source: Make sure the TV is plugged into a working outlet. If using a surge protector, try plugging directly into the wall. • Factory reset (if needed): As a last resort, you can reset the TV to its default settings. (Note: this will erase your personal preferences.) If none of these steps resolve the issue, contact Samsung Support for further assistance at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun), or reach us via text anytime.
