This is usually a low signal issue or there is a lot of noise in your line. Check your connections.
Note by liamsdad23
: Digital channels can also freeze and tile if the signal is too high!
Please refer to my modem troubleshooting section regarding low/bad signal.

- Tiling can also be caused by grounding issues/electrical backfeeds. I lived in a house that was built in 1949 (with older electrical wiring) and the TV was feeding electrical current into the cable lines via the set top box. Backfeeds can also be caused by faulty equipment like the Sony TV that ended up on the curb at 2 years old.

- improperly crimped connectors can cause this... if the dielectric is too far back from the inside of the F-connector (not flush) it will interfere with the center conductor and cause this (known as "pixelation" but the correct term is "macroblocking")
- It is also a shielding issue - bad connectors, loose connectors, chewed cable, old TV coax with no foil shield. This lets in off-air interference frequencies that may affect specific channels or channel groups.
