If your TV screen is fuzzy or pixelated in some channels, hardware issues are less likely to happen. To fix the pixelation problem in certain channels, you can follow the tips below one by one:

1. Remove every obstacle or clutter near your TV and antenna.
2. Check your antenna connection to see if it’s properly connected.
3. Connect the TV with a signal amplifier.
4. Run a channel scan as this may resolve the issue.
5. Use a rotor or an attenuator with the television.

If none of the above tasks work, you can call your cable operator and let them fix the issue.
