Hi Noonhike7, Thank you for purchasing the Samsung AU8000 TV and for sharing your experience with your TV not displaying properly. Samsung prides itself on high-quality products and a great customer experience. Please know we are here to help you. Please try the following troubleshooting steps to help resolve your issues with dark blotches: 1. If any external devices are connected, check all input cable connections 2. If the issue persists, define exactly 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 (which 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, don't hesitate to get in touch with Samsung Customer Support at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
