Hi Ha2026, 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 > Left directional key > 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 > Left directional key > Settings > Support > Software Update 3. Run Built-In Diagnostics • Perform a Picture Test: Home > Left directional key > 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 > Left directional key > 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.

Hi Stacy, Thank you for sharing your experience with Wi-Fi connectivity. If your TV is having trouble connecting to the network, the following steps may help resolve the issue: Signal & Setup Tips: 1. Check TV-to-router distance – Your TV should be within 50 feet of the modem or access point for reliable signal strength. 2. Minimize interference – Turn off nearby wireless devices and make sure there are no physical barriers (stone walls, fireplaces, appliances) between the TV and router. Power Cycle Devices: 3. Restart both your TV and router – Unplug both devices for at least 30 seconds, then plug them back in and allow them to reboot fully. Connection Type: 4. Evaluate your connection method – o If using Wi-Fi, move your router closer to the TV and eliminate any obstructions. o For a more stable connection, we strongly recommend using a wired Ethernet cable. o If already using Ethernet, verify the cable is working by testing it with another device. Run Built-In Diagnostic Tools: 5. Network Test: Settings > Support > Device Care > Self Diagnosis > Smart Hub Connection Test 6. Wi-Fi Check: Settings > Support > Device Care > Self Diagnosis > Wi-Fi Last Resort: 7. Perform a Factory Reset (if issues persist): Settings > All Settings > General & Privacy > Reset > Factory Data Reset. Note that this will return all settings to their original defaults. If these steps don’t resolve the issue, please reach out to Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
