Common Problems and Solutions

1.The matrix front panel switching keys not responsive?

Answer: The matrix front panel keys employ scanning testing and require longer response time. Press the keys for 2 seconds and then release. This way, key switching will be responsive in operation.

2.The matrix does not display or color display is abnormal after hot plug?

Answer: Switching of the signals goes through the matrix ICs. If the voltage difference between the input signal equipment and the matrix equipment is too large, hot plug could easily cause damage to the matrix switches. Turn off power to the system before plugging or unplugging.

3.Ghosting happens when YPbPr signals output to display?

Answer: Ghosting is often caused either by the projector, inferior cable quality or long transmission distance. Adjust the projector or replace with better quality cable.

4.Loss of color reproduction happens or no video signal output?

Answer: Check if connectors at both ends of the YPbPr signal cable are correctly connected.

5.The serial port fails to control the matrix?

Answer: Check that the communication port set by the control software is correctly connected to the corresponding serial port of the equipment. Verify the serial control parameters (9600, 8, N, 1).

6.The corresponding graphics fail to output during matrix switching?

Answer:

(1)Check for a signal on the input end. If there is no input signal, it could be that the input connection cable is broken or the connector is loose. Repair or replace the connecting cable.

(2)Check if there is signal on the output end. If there is no output signal, the cable could be broken or the connector is loose. Reseat or replace the connecting cable.

(3)Check if the output port number is the same as the controlled port number.

(4)If none of the above circumstances happen, it could be internal failure of the product itself. Call 469-429 9200 for technical support.

7.The power LED is not on, LCD has no display and no response in operation?

Answer: Check if the equipment power input is good. Check the power at the AC outlet and that the power cord is firmly connected at both ends.

8.Power leakage sensed during plugging or unplugging of the audio/video ports?

Answer: It could be that the equipment power is not properly grounded. Properly ground the equipment, otherwise product life may be shortened.

9.The LCD displays normally, the communication port shows good return codes, but displays no graphics or audio output?

Answer: (1) It could be that the audio/video connectors are loose. Replace the connectors.

(2)It could be the connection cable short-circuited. Replace the cable.

(3)It could be the connection cable is broken. Replace the cable.
