“Got this tv brand new 4 months ago and last night these lines appeared out of nowhere and I can’t get them to go away. Checked online and it says most likely a bad internal panel? Anyone know if it can be fixed or am I just stuck with a lemon?”

Mrpark, Thank you for sharing your experience with your TV not displaying properly. Please try the following troubleshooting steps: 1. If any external devices are connected, check all input cable connections 2. If the issue persists, define precisely what is wrong with the display. For example, mosaics and blocks, multiple lines or white dots, and fixed horizontal or vertical lines. 3. Try changing channels using the remote control. Is the issue the same on all channels? 4. Press the Home button (looks like a house), select Source, and choose another input source. Is the issue the same on all sources? 5. If the same problem persists, run a diagnostic test. (Home > Settings > Support > Device Care > Self Diagnosis > Picture Test) 6. If the problem disappears during the test, check your TV signal (Home > Settings > Support > Device Care > Self Diagnosis > Signal Information) to check the signal strength. The signal strength must be more than 20 dB (more than 4 bars on the icon) for stable signal reception Should your issue persist, please contact Samsung Customer Support.
