Keep Your Display
Performing At Its Best.
LED displays are systems, not just screens. When something goes wrong, the cause can be related to modules, power, signal, controller settings, calibration, environmental conditions or installation. The right support process starts by identifying the actual problem.
What Can Be Checked?
LED display issues can come from several parts of the system.
Dead Pixels & Modules
Identify dim, dead or inconsistent modules and determine whether replacement or further diagnosis is appropriate.
Power & Wiring
Check power supply, distribution, connections and possible electrical issues affecting display sections.
Signal Problems
Investigate HDMI, data, receiver-card and signal-chain issues when the display shows no or unstable content.
Controller Issues
Review controller configuration, sending systems and processor settings when supported by the hardware.
Brightness & Colour
Investigate brightness differences, colour drift, white balance and visible uniformity problems.
Mounting & Structure
Review visible mounting concerns and identify when professional structural inspection is required.
Outdoor Conditions
Outdoor systems may require checks for dust, water ingress, seals, weather exposure and environmental damage.
Preventive Maintenance
Scheduled inspection and calibration can help identify problems before they become major failures.
Give Us The
Right Information.
A few simple details can help technical support understand the issue faster. If possible, share photos or a short video of the problem along with the screen details.

Technical support recommendations depend on the specific display, hardware configuration, installation condition and issue. Do not open electrical cabinets, disconnect power systems or perform structural work unless you are qualified and it is safe to do so. For uncertain or potentially hazardous issues, seek professional technical assistance.
