High Definition Television Troubleshooting
• If you do not have a picture on your HDTV, turn off all equipment and check your connections. Some
connectors such as HDMI can slip loose of the equipment, in which case you’ll want all equipment
off when reconnecting.
• If the picture is not displaying correctly with a digital connection, you may need to switch to an
analog connection to troubleshoot your settings.
• The DCT output settings must match your HDTV input settings. To check the DCT output settings,
turn the DCT off and hold down the Info and Guide buttons on the front panel at the same time.
To check your HDTV input settings, check the manual or contact the support department for your
HDTV manufacturer.
• Many home theater systems use automatic switching, allowing you to connect multiple devices to
the receiver, and connect a single cable from the receiver to the television.
• If you use a receiver between the DCT and your HDTV and encounter any problems, try bypassing
the receiver. Some receivers do not relay all digital copy protection signals, which prevents the
picture from being displayed.
• If you have no sound and are using a stereo tuner, check the connections to and settings for the
tuner. If you have no sound only on HD channels, your system may not be compatible with the
multi-channel audio formats available with HDMI and SPDIF. If this is the case, set the digital audio
setting for your HDTV or stereo tuner to PCM. This will convert the digital signal to an analog form
the equipment can use.
• If any additional equipment in your home theater is not working correctly, you will want to refer
to the user manual(s) for that equipment, or contact the support department for that equipment.
The settings on audio/video equipment vary greatly from one manufacturer to another, and Wave
Broadband technical support is not trained to troubleshoot third-party equipment.
HDTV FAQs
Q. What do I need in order to receive HDTV?
A. In order to receive HDTV, you must have a HD television and one of the following: HD cable receiver,
HD/DVR receiver, or HD cable card from Wave Broadband. Your high definition television must have an
HDMI, YPbPr component or DVI input and must support either 720p or 1080i HD format. Refer to your
television’s user manual to determine if your HDTV set supports either of these formats.
Q. I already have a high definition television. Do I still need an HD receiver?
A. Yes. To receive Wave HDTV service, you must have an HD television and one of the following: HD
cable receiver, HD-DVR receiver, or HD cable card from Wave Broadband that enables you to watch
HDTV programming.
Q. What is the difference between HDTV and digital cable?
A. Digital cable is a type of television signal. HDTV is the highest quality in digital signals, offering better
resolution and sound than a standard digital signal. Digital cable can be watched on your existing
standard television if you have a digital cable box. HDTV requires both a high definition television
capable of displaying 720p, 480i and/or 1080i and a high definition cable box.
Q. How will high definition service look on my regular analog television?
A. HD signals will not display on regular analog TV sets, since those TVs don’t include the advanced
technology required to display HD signals.
