TROUBLE-SHOOTING
1. Best results are usually achieved when the source and display resolutions are the same. If resolutions
differ, the splitters 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 splitters using the button on the front panel. 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 splitters 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 Matrix Switch and plug the cable into it, then plug the output cable into the
receivers and finally turn-on the display and plug the HDMII cable from the receivers 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 Cat 5e or Cat 6 cables
used. The HDMI signals run at digital data rates, which are at least ten times faster than for conventional
Ethernet. If 8-position modular plugs are attached in the field, the connection may not be able to support
the HDMI signal. This is why factory terminated assemblies are strongly recommended. To determine if
the field-assembled cables are at fault, move the source close to the display and connect with a 3 ft or 6
ft computer cable assembly.
7. Check the batteries in the remote control that was supplied.
