Geejay: Thank you for purchasing the Samsung TU7000 TV. I am very sorry you experienced a brief issue with your TV not displaying properly. Should this happen again, you may want to try the following troubleshooting steps: 1) Check the antenna and input cable connections 2) Check the antenna and HDMI cable connections 3) If the issue persists, define exactly what is wrong with the display. For example, mosaics and blocks, multiple lines or white dots, fixed horizontal, or vertical lines 4) Try changing channels using the remote control. Is the issue the same on all channels? 5) Press the Home button (looks like a house), select Source, choose another input source. Is the issue the same on all sources? 6) If the same problem persists, run a diagnostic test. (Home > Settings > Support > Device Care > Self Diagnosis > Picture Test) 7) 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. Signal strength must be more than 20 dB (more than 4 bars on the icon) for stable signal reception Should you need further assistance, please contact Samsung Customer Support. 1-800-SAMSUNG (ask for TVs), available 8AM -12AM EST, 7 days a week Or visit us on the Samsung website and click on the ‘Support’ link in the upper right corner of the homepage for: 1) Contact Us Options (LiveChat, Remote Support, Facebook, Twitter) 2) Product Support 3) Manuals and Downloads 4) Warranty Info 5) Product Registration: Registering your product gives you access to easy warranty support, convenient opt-in to special promos and offers, faster troubleshooting and service, and quick notification of system updates 6) Samsung Community: A great resource for getting help from Samsung moderators and customers and more 7) …and more product, repair, order, and care options ~ Samsung Solutions
