7.0 TROUBLESHOOTING
• Make certain that the matrix is receiving power by looking at the power LED.
It should be illuminated and not flickering. Intermittent operation generally
means a problem with the DC power adapter or low AC voltage. Check the AC
outlet for proper voltage, then consider replacing the DC power adapter.
• If some lower resolution TVs do not display a picture, make sure the source is
producing a resolution low enough that all TVs can accept it. Try 1080i, 720p
and 480p. If possible, manually set your sources to the desired resolution.
In some cases, hot-plugging a high resolution display may actually reset the
source to a resolution that cannot be accepted by some other TVs.
• If displays seem to “lose signal” momentarily, this may be normal HDMI
switching behavior. All displays connected to a source must handshake again
when that source is selected to a new display. This pause is normal and
required when switching HDCP encrypted signals.
• If some inputs function correctly and others do not, interchange cables
between sources and see if the problem moves with the cables. If it moves,
a bad cable or cable connector is the probable reason for the trouble. If the
problem remains with one particular input, connect that source to a different
input using the same cable and see if the problem moves to the new input. If it
does, the problem is with the source. Connect the source directly to the lowest
resolution display and adjust its output settings and resolution until satisfactory
function is achieved.
• If 1080p resolution is desired, first make certain that the input cable is as short
as possible and none of the output cables are more than 15 meters long.
HDMI cable design and quality are extremely important in long cable runs
where capacitance can severely effect performance. One of our high quality
HDMI extenders should be used in extreme length/high bit depth applications.
• Remember that HDMI devices communicate with one another so the source
device and all destination devices must be fully HDMI compliant. In addition,
HDCP encryption requires processing dependent on the equipment you have
connected to both the source and destination devices.
