I'm sorry to hear that you're having this issue.
If you're only experiencing this on some channels, the broadcast signal can be weak or compressed, and this can cause some picture artifacts that are less than pleasing.
You also may experience some improvement by adjusting the settings in the cable/sat box, Blu-Ray players and other attached devices to ensure that you're receiving the highest resolution possible. Component and HDMI cables are also recommended for HD viewing, and can also be the source of some of these symptoms.
If none of these suggestions help, you may want to have your unit inspected, and you can do that at 800-SAMSUNG or filling out the online request form here:http://www.samsung.com/us/support/o...
