Hi Samsung,Thank you for purchasing the Samsung AU800D TV and for sharing your experience with your TV not displaying properly. You may want to 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. 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 at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
