Repairs & Emergency Fault Response
We’re experienced in diagnosing and repairing the most common (and most frustrating) LED display issues, including:
Dead pixels, stuck pixels, and “sparkles”
Lines, blocks, or black modules
Brightness or colour inconsistency
Flickering, artefacts, or refresh issues
Power supply faults and power distribution problems
Receiving card / sending card / HUB board faults
Data and signal issues (cabling, fibre, converters, routing)
Environmental damage (water ingress, corrosion, overheating, dust)
Cabinet alignment, physical impact damage, and connector issues
Where possible, we aim to triage quickly (often remotely first) and then recommend the fastest, most cost-effective fix — whether that’s an on‑site repair, module swap, or return-to-base repair for specific components.
Planned Preventative Maintenance
Most LED display failures aren’t “random” — they build up over time. Planned maintenance helps you protect uptime, extend lifespan, and keep image quality consistent.
A typical maintenance visit can include:
Visual inspection and diagnostics (modules, PSU, receiving cards, cabling)
Cleaning and airflow checks (fans, filters, vents, internal dust build-up)
Brightness/colour checks and uniformity review
Connection integrity checks (power + data)
Weather seal checks for outdoor screens (where applicable)
System health reporting and practical recommendations
If you’re running LED for retail, venues, corporate spaces, DOOH, transport, or public-facing signage, preventative maintenance is usually the cheapest way to reduce downtime over the year.
LED Screen Service Contracts (for any brand of display)
If you need priority support and predictable maintenance, we offer LED screen service contracts and support agreements for:
Single sites (one screen / one location)
Multi-site rollouts (regional or national estates)
Dynamo systems and non‑Dynamo displays
Service contracts can be tailored to your operational needs and may include:
Scheduled preventative maintenance visits
Priority fault response (response-time options available)
Remote diagnostics and support
Spare parts strategy (recommended spares list / holding stock options)
Documentation support for sites that require it (RAMS/permits where applicable)
If you’re specifically looking for a maintenance contract or service contract for an LED screen, tell us your location, screen size/pixel pitch (if known), and access requirements — and we’ll advise the best coverage level.
Warranty & Extended Cover Options
For Dynamo-supplied LED displays:
3‑year warranty as standard
Option to extend to 5 years (for additional peace of mind)
If you want faster restoration and reduced disruption, you can also add an on‑site service contract alongside the warranty cover.
Warranty and service terms vary by system and site conditions — we’ll confirm the most suitable option when quoting.
Dead Pixel & Module Repair
Do you have LED panels with chip errors, dead pixels, or module faults?
In many cases, module repair or targeted replacement is far more cost-effective than replacing an entire screen. If you can share photos/video of the issue (and the module/cabinet type if known), we’ll advise the quickest route to restore image quality.
