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.
6.
If you have problems with the IR control circuit, make sure that the IR RX pigtail is
plugged into extender receiver and pointed at the display, and the IR TX pigtail is
attached to the extender sender and pointed at the source.
