7. Common Questions and Solutions
In this chapter
This chapter mainly introduces common fault problems and solutions of the
video processor, specific content as follows:
1）When there is ghost in matrix peripheral display device images,
for example, the projector has ghost, generally, it is not caused by
the host:
 Maybe the projector is not adjusted probably or the wire quality is not
standard, adjusting the projector button or replacing the wire is
needed.
 Maybe the wire is too long and cause signal attenuation, adding a long
wire drive is needed.
 Maybe hybrid installation with the 220V high voltage.
2）When there is color loss or no video signal output, maybe it is
caused by poor contact of video interface or break.
3）When COM (generally refers to: computer serial port) can not
control the matrix, check if the communication port that controls
software set is corresponding to device serial port; Check if the
computer communication port is in good condition.
4）No corresponding image output when matrix switching:
1. Check if the corresponding input has any signals, (or test with
oscilloscope or multimeter). If there is no signal input, may be the input
connection is broken or joint is loose, you can replace the connecting
line.
2. Check if the corresponding output end has any signals, (or test with
oscilloscope or multimeter) if there is no signal output, may be the input
