10.0 Common Problems and Solutions
1. What to do if the VAX matrix front panel keys switching not responsive?
Answer: The VAX 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. What to do if matrix does not display or color display is abnormal after hot plug?
Answer: Switching of the matrix system goes through the IC chips. If the voltage difference
between the input signal equipment and the matrix equipment is too large, hot plug
could easily cause damage to the IC chips. Please turn off power to the system before
plugging or unplugging.
3. What to do if ghosting happens when VGA signals output to display?
Answer: Ghosting is often caused either by the projector, inferior cable quality or long
transmission distance. You are advised to adjust the projector or replace with better
quality cable.
4. What to do if loss of color reproduction happens or no video signal output?
Answer: Please check if connectors at both ends of the VGA signal cable are correctly
connected.
