Frequently Asked Questions
What causes LED billboards to fail?
Most failures are caused by power supply problems, voltage spikes, moisture ingress, heat stress, ageing LED modules, controller faults, or damaged cabling and connectors.
My LED billboard is on, but some sections are dark — what does that mean?
This usually points to failed LED modules, loose connectors, a faulty receiving card, or a power distribution issue feeding that section. A structured diagnostic check confirms the exact cause.
Why does the screen flicker or show unstable brightness?
Flicker is commonly linked to power instability, grounding issues, failing power supplies, incorrect refresh configuration, or control card problems. We test power first, then confirm controller and signal integrity.
Why are the colours wrong or washed out?
Incorrect colours can be caused by calibration drift, module ageing, configuration issues, or failing components in the signal chain. Calibration and component checks usually restore accurate colour output.
Do you repair outdoor LED advertising screens?
Yes. We specialise in outdoor LED billboards and digital advertising displays that operate in harsh environments, including heat, rain, dust and vibration.
How do you diagnose a fault on an LED billboard?
We typically start with a safety and power check, then test the power supplies, controller and receiving cards, signal flow, cabling, and modules. This root-cause approach reduces repeat failures and unnecessary replacements.
Can you help prevent breakdowns in the future?
Yes. Preventative maintenance reduces downtime by catching early-stage issues like moisture ingress, overheating, loose connections and degraded modules before they cause a full outage.
How often should LED billboards be serviced?
For most outdoor LED screens, a preventative inspection every 3 to 6 months is recommended. High-traffic or harsh environments often benefit from more frequent checks.
Do you offer emergency or after-hours support?
Yes. We provide standby after-hours support for critical faults, especially when downtime affects live advertising campaigns. Response is arranged based on location and urgency.
Which areas do you service?
We are based in Centurion and service Gauteng and surrounding regions, including Witbank, Rustenburg, Middelburg, and nearby areas. If you are unsure, contact us and we’ll confirm availability.
What information should I send you to speed up support?
If possible, share the location, a brief description of the fault (e.g. “top-right quadrant dark”), when it started, and a few clear photos or a short video. This helps us prepare parts and reduce downtime.
Do you only repair, or can you also upgrade components?
We can assist with repair-first solutions, and where appropriate we can advise on upgrades such as power supply improvements, controller replacements, or reliability improvements that reduce repeat failures.
