Reprogramming a Comcast digital cable box involves entering the device's settings menu and changing things around to fit your needs. For example, you can change the aspect ratio of the image being received to match that of your television set or change audio settings. You don't have to make an appointment for a Comcast technician to come to your home and make these changes---you can easily do this yourself manually in just a few seconds.
Things You'll Need
- Comcast digital cable box and remote control
Press the "Menu" button on your Comcast digital cable box remote control. This will display the cable box's settings menu on your TV screen.
Select the appropriate aspect ratio under the "Aspect Ratio" setting. If you have an LCD or plasma TV, select the "16:9" option. If you have a cathode ray tube television, select the "4:3" option.
Select the "Picture" setting to select either "SD" (standard definition) or "HD" (high definition). Only select "HD" if you have an LCD or plasma television set.
Select the "TV Type" option to specify the type of television set you own. If you have an LCD or plasma TV, select "Widescreen." If you have a CRT TV, select "Standard."
Specify your preferred audio settings by selecting the "Audio" category. You can choose either "Low Compression" or "High Compression." Low compression audio will provide better audio quality, but you will only be able to hear the difference if you are using a home theater surround-sound system. If you are just listening to the audio using your TV's built-in speakers, select "High Compression."
Tips & Warnings
- Any other settings you need to adjust (such as picture settings like brightness and sharpness) will have to be done using your TV's remote, not your Comcast cable box's remote. In the event that you lose power and your channels need to be reset, the box will slowly do so automatically. If it does not, contact your local Comcast customer service department (by dialing 1-800-COMCAST) and they will do it on their end. This is not something you can do manually.
