Hi Andres,<br /><br />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:<br /><br />1. Check all input cable connections for any external devices (e.g., HDMI, streaming boxes, Blu-ray players)<br />2. Switch channels or inputs to see if the issue appears across all sources<br />3. Run a Picture Test to check for panel-related issues: Settings &gt; Support &gt; Device Care &gt; Self Diagnosis &gt; Picture Test<br />4. Perform a cold boot by holding the power button on your remote for about 10 seconds<br />5. Ensure your TV has the latest software installed: Settings &gt; Support &gt; Software Update<br /><br />If the issue continues after these steps, the TV may require service.
