How to Bypass the Filter on Cable

Coaxial cable used to connect to a cable box.

Cable boxes that are connected to a television with a coaxial cable will need to use channel 3 or 4 on the television to view the signal from the cable box. This means that there may be a highpass filter installed that will remove channels 2, 3 and 4 to allow the cable box to work properly. You can bypass the need to use a highpass filter with your cable box by connecting it to your television with a component audio and video cable.

Things You'll Need

• RCA component audio and video cable

Instructions

Disconnect Coaxial Cable

1. Disconnect the coaxial cable from the splitter/combiner that is connected to the coaxial cable running from the wall jack.

2. Disconnect the coaxial cable from the video input on the cable box

3. Disconnect the coaxial cable that is connected to the video output on the cable box.

4. Disconnect the coaxial cable on the splitter/combiner that is connected to the coaxial cable running to the television.

5. Disconnect the coaxial cable that is connected to the video input on the television.

6. Set the coaxial cable and the highpass filter aside.

Connect RCA Component Cable

1. Connect a coaxial cable from the wall outlet to the video input on the cable box.

2. Connect one end of the component audio/video cable to the component audio/video output on the cable box.

3. Connect the other end of the component audio/video cable to the component audio/video inputs on the television.

4. Turn on the television and press the "Input" button until you see a picture from the cable box on the screen.

Tips & Warnings

• If you do not have an RCA component video, you can use a standard RCA audio/video cable to connect the cable box to the television.
