Hi Coleslaw, Thank you for sharing your experience with Samsung’s U7900F. If your TV is displaying lines on the screen, we recommend the following steps to help isolate the issue: 1. Check all input cable connections for any external devices (e.g., HDMI, streaming boxes, Blu-ray players) 2. Switch channels or inputs to see if the issue appears across all sources 3. Run a Picture Test to check for panel-related issues: Settings > Support > Device Care > Self Diagnosis > Picture Test 4. Perform a cold boot by holding the power button on your remote for about 10 seconds 5. Ensure your TV has the latest software installed: Settings > Support > Software Update If the issue continues after these steps, the TV may require service.

Hi None, If your U7900F TV is taking longer than usual to power on, load apps, or navigate menus, here are a few steps that can help restore normal performance: 1. Try a Cold Boot (Power Reset): With the Samsung remote: • While the TV is on, press and hold the Power button on the remote. • Keep holding until the TV turns off and back on. Without the Samsung remote: • While the TV is on, unplug the power cord from the wall outlet. • Wait 30 seconds, then plug it back in and turn the TV on. 2. Check for Software Updates: Outdated software can affect performance. Go to: Home > left directional key > Settings > Support > Software Update > Update Now 3. Run Device Care: This tool frees up memory, closes background apps, and can improve speed: Settings > Support > Device Care > Start Device Care If you’ve tried these steps and your TV is still slow to respond, feel free to contact Samsung Support for further assistance at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat and additional support resources are also available through the Support link on our website. ~Samsung Advisor
