    Display/picture issue.
    • Check if the connection and input settings on your set top box are correct.
    • Compare the picture from the set top box with the picture from the TV or other input devices.
      For example, if the set top box (TV OUT) is connected to TV (RF IN) using an RF cable, try to switch the input to TV and compare the picture. If the TV picture has no issue, then the issue is with the set top box. In this case, contact your set top box service provider.
      You may also playback a movie from other sources like Bluray players for comparison.
