Troubleshooting

After input and display devices are connected to the distribution amplifier and all units are powered up, the system is fully operational. If any problems occur, ensure that the cables are properly routed and connected. Some common problems and diagnostic checks are shown below:

If the LED light on the front panel is not on, the distribution amplifier is not receiving power. Ensure that the electric outlet is functional and that the power cord is correctly connected (see page 2-7).

If there is no image on the display device, check that there is an input signal. If the LED light is amber, the power is on but the distribution amplifier is not receiving an input signal. Verify that the cables are correctly connected from the input device and that the input device is switched on (see pages 2-9 and 2-10).

If the front LED is green but there is still no output signal:

•Check that the cables to the output device are connected correctly (see pages 2-9 and 2-10).

•Make sure that the output for that channel has not been muted (see page 2-11).

•Change the sync impedance of the output to 75 ohms on the front panel (see page 2-8).

If the source is a laptop computer, which is providing an unstable output image, ensure sync impedance switch number 1 (input sync) is in the ON position (see page 2-8).

If output 1 supports an image but other display devices do not, ensure that the resolution capabilities of the display device on output 1 does not exceed the resolution capabilities of output devices on the other channels. For optimal performance, all display devices should have similar resolution capabilities (see page 2-9).
