5. 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:
 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.
 Check if the corresponding output end has any signals, (or test
