Hi, Thank you for sharing your user experience. If your TV’s picture or sound settings keep resetting after a few minutes, it’s likely that Usage Mode is set to Retail Mode. This mode is intended for in-store display and will automatically reset certain settings every 5 minutes. To resolve this, change the Usage Mode to Home Mode by navigating to: Home > Settings > All Settings > General & Privacy > Usage Mode > Home Mode If you need help making this change or have additional questions, please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents are also available on our website. ~ Samsung Advisor

Hi Debbie, Thanks for reaching out about the intermittent black screen issue. If you're not using any external devices and the TV randomly cuts to black, it’s usually related to settings, signal, or internal software. Here are a few steps to help narrow it down and get things stable again. 1. Start with Power & Source Checks • Confirm the source: Even without external devices, it's worth confirming the TV is on the correct internal source (like TV/Live TV or a streaming app). Go to: Home > Connected Devices > Sources • Power cycle the TV: Unplug the TV from the power outlet for at least 60 seconds, then plug it back in. This can help reset any temporary glitches. • Check the power outlet: If you're using a power strip or surge protector, try plugging the TV directly into the wall to rule out inconsistent power delivery. 2. Update Your TV Software: Software updates often resolve bugs that can cause screen flickers or blackouts • Make sure the TV has the latest firmware version installed: Home > Settings > Support > Software Update 3. Run Built-In Diagnostics • Perform a Picture Test: Home > Settings > Support > Device Care > Self Diagnosis > Picture Test. This helps determine if the issue is hardware- or software-related. • Run the HDMI Test (optional): Even without HDMI devices connected, this can help verify that internal ports are functioning properly: Home > Settings > Support > Device Care > Self Diagnosis > HDMI Test 4. Review Energy & Picture Settings • Turn off Power Saving Mode or Eco Solution settings—they can dim or turn off the screen during periods of inactivity: Settings > All Settings > General & Privacy > Power & Energy Saving • Turn off Auto Power Off (if enabled): Settings > All Settings > General & Privacy > System Manager > Auto Power Off • Adjust Picture Mode settings: If the current mode is overly dynamic (like “Dynamic” or “Vivid”), try switching to “Standard” or “Movie” and observe if the screen behavior changes. 5. Factory Reset (if needed): If the problem persists after all checks, consider resetting the TV to default settings. (Heads-up: this will erase your installed apps and personal settings.) If none of these steps resolve the intermittent blackout, please reach out to Samsung Support for further troubleshooting or possible service options at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun), or reach us via text anytime.
