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.

Hi Randyfish, We appreciate your feedback on the M70HD TV. For the most optimal performance, please ensure your TV and headphones are up to date with the latest software. To update your TV, go to Settings> Support> Software Update. Please also note that the TV and Bluetooth device may disconnect if the distance between them is too great or if there are obstacles. Next, buffering during streaming is typically related to internet speed or signal strength. This can happen when your connection isn’t able to deliver data quickly enough for smooth playback. We recommend the following steps to help improve streaming performance: 1. Use a 5GHz Wi-Fi connection, if available 2. Try a wired LAN connection for more stability 3. Reposition your router to minimize obstacles between it and the TV 4. Make sure your TV is running the latest firmware (Settings > Support > Software Update) 5. Run Device Care to optimize performance: Home > left directional key > Settings > Support > Device Care > Start Device Care If buffering continues, you may want to contact your internet service provider to check your current speed or explore upgrade options. If we can assist further, please call us at 1-800-SAMSUNG, (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
