fault is not eliminated in the previous two steps, connect the LCD display
at the failed display unit to check the HDMI signal. Try to replace the
HDMI signal cable. If the image of the display unit with replaced panel
cannot be connected with peripheral device, use the address coordinates,
brightness and color values corresponding to the software settings are
required.
3. Image flashes on part
of LED screen.
1. Fault in cascade signal transmission of the display unit. Try to replace
the HDMI signal cable. If the image of the display unit with replaced panel
cannot be connected with peripheral device, use the address coordinates,
brightness and color values corresponding to the software settings are
required.
2. Fault in input signal. Connect the display screen with the LCD display
for check.
4. The LED display
module is not normal, all
or part of the module is
lack of color, bright for
long time, or out of
control or in the
semi-uncontrolled state.
1. The display unit initialization is not normal, restart the power of this
area, with the interval of no less than 1min. Sometimes 2-3 times of restarts
may be required to eliminate the fault.
2. If the fault is not eliminated in Step 1. It may be caused by poor contact
between the LED module and the control panel, re-plug them.
3. If the fault persists after the above two steps, it may be considered that
the LED module or the control panel circuit is likely broken. Replace the
LED module or the control panel to solve the problem. In this case, the
coordinates, color and brightness should be adjusted so that they are
consistent with those of the full screen.
5. Incomplete image in
the video window
1. Connect the LCD display to check if the video processor's signal input or
output is normal.
2. Check if the input signal resolution matches with the one that has been
saved.
3. Check if the video processor is set up correctly.
When the LED display is abnormal, analyze in which link of the screen the fault occurs according to
experience, combined with specific situations. The fault is finally determined to be from a component of
the display unit, we recommend that it replace the component on site directly as recommended. With
respect to LED light board module, power supply or LED control panel, etc., for example, it is required
that the software reads the data back to the LED control panel after the LED module is replaced. And then
complete the software setting. Refer to the chapter involving guideline for software operations.
