TROUBLE-SHOOTING
1. Best results are usually achieved when the source and display resolutions are the same. If resolutions differ, the
extenders will try to adjust the signal to match the resolution of the HDTV with the lowest resolution. This will result in a
picture with a lower resolution on the other HDTV sets.
2. If you do not get audio and video, access the “setup” menu on the TV to adjust the audio and video settings. If the HDMI
control circuit cannot establish a handshake, then there usually will be no audio or video in addition to a blue or black
screen with a statement similar to “this protocol not supported” or “weak signal”.
3. If the above mentioned messages display, reset the receiver by disconnecting the power supply. You can also disconnect
all of the HDMI and power cables, wait 15 minutes for any voltages to decay and then reconnect all of the cables.
4. If you are still encountering issues, attempt the “hot-plug concept. With all of the HDMI cables disconnected, turn on
the source and plug in the HDMI cable into it’s output, then power up the Vanco unit and plug the HDMI cable into it’s
input, finally turn on the display and plug the HDMI cable from the receiver into it. This activates all of the devices in
corresponding order and results in a signal being plugged into a device that is on and will attempt to connect the signal.
5. Most of the major source and display manufacturers employ a proprietary control channel to communicate between
devices from the same manufacturer. Sometimes this can interfere with the HDMI control circuit or the authentication
of the signal. Call the manufacturer if you experience this issue. Sometimes a player, an audio/video receiver, or a cable/
satellite box may not have the latest software update, usually this can be downloaded from the manufacturer’s website.
