Hi Doomstyker, Thank you for sharing your experience with Samsung’s U8000F. 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 It is also possible that the TV was damaged during transit, if care was not taken.
