Blocks or a frozen picture are symptoms of pixilation (also known as tiling).
Occasionally pixilation is a result of problems at the content provider but may also occur during high-motion programs, such as sporting events-when the background picture changes faster than the foreground picture. If it happens regularly, it could be a wiring or equipment problem.
For further assistance, contact TDS TV at 1-866-44-TDS-TV (1-866-448-3788). It's helpful if you are able to provide the date, time and channel when the pixel issue occurred.
