Common Questions and Solution
1. When there is double image in matrix peripheral
display device images, for example, the projector
has double image, 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 with oscilloscope or multimeter) if
there is no signal output, may be the input connections
is broken or joint is loose, you can replace the
connecting line.
● Check if the output port is in accord with the
controlled port.
● If not belong to above three circumstances, maybe it
is caused by host internal fault, please send to
professional for maintenance.
5. If there is no display in LCD and no reaction for
operation, please check if the power input is good
contacts.
6. If the output image is disturbed, maybe the
input/output devices without good ground.
7. If there is obvious electrostatic when drawing or
inserting audio and video interface, maybe the
power ground without good ground, please ground
with the right way, otherwise, it will easily damage
the host and shorten the host life.
8. LCD display is normal, communication port
has return code, but no image output or no
audio output:
● Maybe the AV interface is loose, you can just plug
it tightly;
● Maybe it is short connection, you can just change
it;
● Maybe wire is broken, you can just change it.
9. If matrix panel button, communication port can
not be controlled, maybe host internal is
damaged, please send to professional for
maintenance.
