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 HD TV with the lowest
resolution. This will result in a picture with a lower resolution on the other HD TV sets.
2. If you do not get audio and video see if you can use the “set-up” menu on the TV to adjust the audio
settings and the video settings. If the HDMI control circuit can’t establish a hand-shake, then there usually
will be no audio or video and a blue or black screen with a statement like “this protocol not supported” or
“weak signal”.
3. If you get the above messages, re-set the Receiver by disconnecting the power supply. Alternately, you can
disconnect all of the HDMI and power cables, wait 10 or 15 minutes for any voltages to decay and then
connect all of the cables from the source, to the Receiver and to the display.
4. If you still have trouble, then try the “hot-plug concept. Turn-on the source and plug the HDMI cable to it
and then power-up the Transmitter and plug the cable into it, then plug the output cable into the Receiver
and finally turn-on the display and plug the HDMII cable from the Receiver into it. This activates all of the
devices in order and results into a signal being plugged-in to a device that is on and will try to connect to
the signal.
5. Most of the major player 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 problem. Sometimes a
player, an audio/video receiver, or a cable/satellite box may not have the latest software update and needs
to have this downloaded from the manufacturer’s web site.
6. If the above actions do not result in a satisfactory result, focus attention on the Coaxial cables used.
7. 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.
