Troubleshooting
Problem: There is no image on the display device.
• Solution 1: Make sure that the power cable is securely plugged into the unit and the A/C
source.
• Solution 2: Make sure the A/C source is live.
• Solution 3: Verify that the power switch is turned on for the video source, the IN1403,
and the monitor.
• Solution 4: Verify the connection to the output display device. Even with no input
signal, the IN1403 menu can be displayed. Press MENU or ENTER to gain
access to the menu screen.
• Solution 5: Select an output resolution and refresh rate compatible with the display
device being used. Use the default power-up buttons to select an output
mode without the menu present, and then turn on the blue screen to verify
these settings.
• Solution 6: The output resolution must be less that the input (the IN1403 can only scale
up). Select an output resolution that is greater than or equal to the input size.
• Solution 7: The display device may not accept certain sync formats. Verify the display
device sync capability and select the IN1403 output sync using the power-up
default buttons.
Problem: There is no audio output.
• Solution 1: Verify that power is present and that the power switch is turned on for the
audio source, the IN1403, and the amplifier/speakers.
• Solution 2: Verify that the audio source is connected to the correct input and that the
source volume has not been turned down or muted.
• Solution 3: The audio output of the IN1403 is line level audio only. It should be
connected to a mixer/amplifier or to amplified “computer type” speakers.
• Solution 4: Increase the volume using the volume UP button.
• Solution 5: The mute may be activated. Press MUTE to deactivate the function.
Problem: The image on the display device is scrambled.
• Solution: Select an output resolution and refresh rate compatible with the display device
being used. Use the default power-up buttons to select an output mode
without the menu present, and then turn on the blue screen to verify these
settings.
Problem: The image on the display device is cropped on the left side.
• Solution 1: Increase the output H-Position to line up the image on the display device.
Use the blue screen.
• Solution 2: Adjust the monitor position or size controls to fit the image on the display
device. Use the blue screen.
