LEDs Are OFF
1. Make sure the MU400-111 Transmitter is plugged into a working AC outlet.
2. Disconnect the MU500-112 Receiver and verify that the LEDs show Idle mode on the
MU400-111 Transmitter. If the MU500-112 Receiver is causing the problem, the MU400-
111 Transmitter will show normal operation.
3. Verify that the cable is properly terminated. For proper pin-out, check the cable with a
cable checker.
Always Idle Mode
1. Verify the display is connected to the MUSE receiver.
2. Check the CAT-6 cable specifications. The CAT-6 cable is critical to proper operation and
power transfer.
Fault LED is ON
1. Disconnect the display from the MU500-112 Receiver and see if the problem is fixed.
2. Disconnect the MU500-112 Receiver from the MU400-111 Transmitter. If the problem is
fixed, wait 10 seconds and then reconnect the MU500-112 Receiver.
3. Reconnect the display; if the fault returns, check the display power requirements.
Note: There is sufficient power for displays rated at 150 W or less. If the display is rated
above 150 W the MUSE will not be able to power the unit. Try another display.
No Video on Display
1. Check the source and make sure there is a signal present.
2. Make sure the display is turned on.
3. Make sure the display is set to the correct HDMI input.
4. If the display is receiving power and set to the correct input, make sure the cables are
connected properly.
5. Switch the source to a lower resolution and check to see if the image is then displayed.
No Sound
1. Make sure the display/TV is not muted.
2. Set the volume on the display/TV to midrange.
3. If the source is a PC/laptop, make sure the sound is set to the HDMI output. On some
computers, this step must be done manually the first time the computer is connected to a
HDMI device.
