Troubleshooting

No Light

This troubleshooting guide is meant to help solve simple problems. If a problem occurs, carry out the steps

below in sequence until a solution is found. Once the unit operates properly, do not carry out following

steps.

If the light effect does not operate properly, refer servicing to a technician.

Response: Suspect three potential problem areas: the power supply, the lamp, the fuse.

1. Power supply. Check that the unit is plugged into an appropriate power supply.

2. The lamp. Replace the old lamp with a new one with the same specifications. See page 8 for

replacing lamps.

3. The fuse. Replace the fuse. See page 29 for replacing the fuse.

No Response to DMX

Response: Suspect the DMX cable or connectors, a controller malfunction, a light effect DMX card

malfunction.

1. Check the DMX cable: Unplug the unit; change the DMX cable; then reconnect to electrical power.

Try your DMX control again.

2. Check the DMX LED on the back of the Matrix. When it is not blinking, the Matrix is not receiving a DMX

signal.

3. Check if the XLR pin connection is OK. A couple of DMX controllers have a switch to change pin 2 and

pin 3. Normally Pin 2 should be Signal -, Pin 3 should be Signal +.

Press this switch on your controller and now Pin 2 is Signal + and Pin 3 is Signal -.

4. Determine whether the controller or light effect is at fault. Does the controller operate properly with

other DMX products ? If not, take the controller in for repair. If so, take the DMX cable and the light

effect to a qualified technician.
