How to Troubleshoot Time Warner Digital HDTV


Time Warner's high-definition television cable service, or HDTV, provides enhanced picture and sound in a wide-screen format. Problems with the HD service can be related to picture aspect -- when the picture doesn't fit within the television screen -- and poor transitioning between standard and HD video. These types of issues can be corrected through troubleshooting.

  • Enter the Menu function of the cable box by pressing "Menu" on the front of the box. Use the arrow keys to highlight "On Screen Display." You can navigate with the remote control, or the buttons on the box.

  • Select the correct settings for your particular television, if the Time Warner HDTV picture isn't fitting properly on your screen. If your TV is widescreen with a 16:9 aspect, choose either "Letterbox 16:9" where black bars will appear above and below the picture; or "Zoom 16:9" where the picture will fill the screen but parts will be truncated; or "Squeeze 16:9" where the image will fit, but be distorted. Select "Sidebar 4:3," "Zoom 4:3" or "Stretch 4:3" if your television is a standard 4:3 aspect television.

  • Change the resolution on the cable box if the displayed picture is of low resolution, but your television supports high resolution. Check with your television's specifications to identify the maximum resolution. Sometimes it's included in the model designation -- for example "1080i," or "720p." Use the setting that indicates the highest setting your television supports.

  • Press the down arrow and choose "4.3 Override" if standard-definition programming isn't being displayed properly. This setting will tell the cable box to send standard-definition programming to your television "as is," and can improve standard-definition viewing.
