Cable TV—FAQ Digital Audio or Video Issues

There are two (2) volume controls—one on the set-top box and one on the TV. If the TV volume control level is down, no matter how high you turn up the volume on the set-top, you won't hear anything. Likewise, if the set-top box volume is down, it doesn't matter how high you set the TV volume, you won't hear anything. You should adjust your TV set volume control about halfway up and leave it alone. Then, adjust the volume through the set-top box.

Try tuning up one channel, and then tuning back down one channel to restore audio.

Check to be sure that your TV is tuned to Channel 3 (you may need to input 03).

If all channels are still out, reset your box by turning it off or by unplugging the power cord. Restore power and toggle through the channels to check reception.

Check the batteries in the remote and make sure your TV is on Channel 3 (you may need to input 03).

Reset the box by turning it off or by unplugging it from the power. Restore power and toggle through the channels to check reception.

Until we can make changes to your buildings distribution system, the cable to your set-top box from the wall plate needs to be split. Using a two-way splitter, feed the cable from the wall to both Antenna and RF inputs on your set-top box. Splitter and jumper cables are available from The Capitol Connection. When you want to watch local channels, turn off the set-top box and select the local channels directly from the channel selector on your TV.

Perform a Google search on the brand and model number and check the spec sheet. Another option is to look for a computer/PC slot on the back of the TV. If there is one, the TV is (or should be) digital-ready.

Digital-ready TVs differ by manufacturer and model. First, make sure you are tuning the digital channels, not analog. You may need to perform a digital/cable (CATV/D) channel auto search. See your TVs instruction manual for performing a channel auto-search. Make sure the TV searches for digital channels. Some TVs are mode-specific, meaning they either search analog or digital. Other TVs search for both types at the same time. In either case, make sure your set searches for the digital channels. Second, make sure that your TV can receive both ATSC digital and QAM digital signals. If you are not sure, call The Capitol Connection and a Customer Service Representative will be glad to assist you.

If your computer is hooked to the set-top box, make sure the tuner card is on Channel 3. Some PC cards, while designated NTSC/ATSC with QAM capability, require a software upgrade. Call The Capitol Connection for help using a PC card to receive TV signals.

Some buildings have a centralized system that relies on what we call a head-end to receive the cable signal. Your IT administrator or office manager may need to reset the box(es) in the head-end that tune the channel(s) with the problem. Reset the boxes by turning them off or by unplugging them and then plugging them back in and/or turning them on again. Call The Capitol Connection for assistance with resetting head-end systems.
