Troubleshooting

Turn on the input devices (DVD players, Blu-ray players, and other sources), output device
(display or projector), the HC 404 system, and the PC.
If an input or output AV device cannot be remotely controlled (does not respond as
expected), if there is no picture or sound, or the output is not as expected, check the
following:

Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (such as use of power strips).
Ensure that all devices are plugged in.
Make sure that each device is receiving power. The HCR 102 front panel power LED
lights if the device is receiving power. The LED corresponding to the selected input
lights. The Signal and HDCP LEDs light for inputs that have an active input signal and
an HDCP compliant signal, respectively.
If the system is in remote power mode [a 12 VDC, 36 watt power supply is connected
to the HCR 102 receiver, which passes power through the twisted pair cable to the
HCT 103 transmitter] ensure that the LED corresponding to each input lights when you
press buttons on the transmitter.
Check the input, unit interconnection, and output cabling connections and make
adjustments as needed.
Ensure that only one input is selected at a time. If an input on the transmitter is selected,
the input 1 LED on the receiver should be off. If input 1 on the receiver is selected, the
LEDs for inputs 2 through 4 on the transmitter should be off. The LED should light for
the selected input. If not, there may be an interconnection cabling error, a lack of power
at one of the units, or a firmware error.
Ensure that the source and display devices are connected and powered on.
If input devices are not available or are malfunctioning, select a video or audio test
pattern via the OSD menu (see
test patterns on the Input/Output Configuration topic within the help file for the PCS
HC 404 module) to provide an output signal for testing.
