9-7. TroubleshootingFollowing are a few common problems that may occur during operation. Here are somesuggestions for easy troubleshooting:A. The fixture does not work, no light11. Check the connection of power and main fuse.12. Measure the mains voltage on the main connector.B. Not responding to DMX controller1. DMX LED should be on. If not, check DMX connectors, cables to see if link properly.2. If the DMX LED is on and no response to the channel, check the address settings andDMX polarity.3. If you have intermittent DMX signal problems, check the pins on connectors or on PCBof the fixture or the previous one.4. Try to use another DMX controller.5. Check if the DMX cables run near or run alongside to high voltage cables that maycause damage or interference to DMX interface circuit.C. Some fixtures don’t respond to the easy controller1. Check the LED for the response of the master/ slave mode signal.2. Check if the unit is receiving DMX signal and cut it off.D. No response to the sound1. Make sure the fixture does not receive DMX signal.2. Check microphone to see if it is good by tapping the microphone.E. One of the channels is not working well1. The stepper motor might be damaged or the cable connected to the PCB is broken.2. The motor’s drive IC on the PCB might be out of condition.
