Solution — Then do one of the following:

There are black bars on all four sides of the picture

This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is OFF. To set 4:3 SD programming to fill the screen, depending on the capabilities of the TV, set 4:3 OVERRIDE to 480i or 480p.

This may occur on a 16:9 TV if the active video for an SD broadcast is in letterbox format. To confirm, wait for a commercial or look for a graphic, such as a network logo. If the commercial fills the screen from top to bottom, or the graphic appears below the active video, the program is being

letterboxed by the broadcaster. You can minimize this by activating the zoom feature on the TV.

A broadcaster may include black bars on either side of a widescreen broadcast. This is called a “hybrid” aspect ratio and results in a black border surrounding the video on a 4:3 TV. Because this is part of the broadcast, the set-top cannot correct the video. You may be able to minimize the

border using the zoom feature on the TV.

Be sure to match up each signal to the same YPbPr connection on the TV.

Colors do not appear Otherwise, colors will not appear correctly on your TV. correctly

The set-top is making a humming noise
