The five factors that decide the price
How much of the screen is affected
One dead module in a 6 by 4 metre wall is a different job from a whole cabinet section that has gone dark. Repairs are scoped per module, per power supply and per card, so the affected count is the single biggest driver of the price.
What kind of fault it is
A module with failed ICs is a component-level repair. A section that flickers or trips power points to power supplies, hub cards or the control chain, which are different parts with different prices. Water and surge damage sit at the expensive end because they often hit several layers at once.
Whether parts are still available
Current-generation modules are straightforward to source. Discontinued modules are not, and that is exactly where component-level repair earns its keep: the module itself is repaired instead of hunting a matching batch that no longer exists. Where a swap is unavoidable, matching an obsolete batch takes sourcing time that shows in the quote.
Workshop or on-site
Workshop repairs are the most cost-effective because the bench allows proper strip down, testing and burn-in. On-site work makes sense for urgent faults and large fixed installations, and the call-out is included in the quote, never added afterwards.
How urgent it is
Jobs are scheduled in the order they are confirmed so every repair gets the same care. If a screen is down during event season or a broadcast window, say so: we will tell you honestly what can be pulled forward and what that does to the price.
What different faults typically involve
Every repair is quoted on its own merits, but faults fall into familiar bands. This is what usually happens for each, and how it tends to sit on the cost scale:
| Fault | What the repair involves | Relative cost |
|---|---|---|
| Single dead or flickering module | Diagnose and repair the module at component level, colour match it against the wall, burn-in test and reinstall. | Lowest |
| Section of the screen dark or patchy | Usually power supplies, hub cards or a ribbon path. We find the common cause instead of replacing every module in the section. | Low to medium |
| Control chain faults | Sending box, controller or receiver card faults that affect the whole wall or random sections. Diagnosed and repaired at board level where possible. | Medium |
| Water or storm damage | Strip down, cleaning, corrosion treatment and component replacement across the affected area. Success depends on how quickly the screen was switched off. | Variable |
Why component-level repair usually costs less
The expensive version of every repair is replacement: swap the module, the cabinet or the whole screen. The affordable version is finding the failed component and replacing that instead. A module that costs thousands to replace new often needs one IC, a handful of capacitors or a repaired track, which is hours of skilled bench work rather than a parts order.
This matters most for older installations. If your modules are discontinued, replacement quotes balloon because matching stock has to be hunted down or the whole face gets swapped for a new batch. Component-level repair keeps the original wall running and looking original.

How TDX quotes a repair
- You send photos or a short video of the fault on WhatsApp, plus the screen brand and rough size if you know them.
- We triage from the photos and tell you which parts of the screen are likely involved.
- You receive a written quote with a fixed price and a realistic timeframe. The price we quote is the price you pay.
- Once you approve, the job is scheduled. We do not bump confirmed work for newer enquiries.
- All repairs carry a standard 6-week warranty on parts and labour.
If the photos are not enough to quote accurately, we say so and tell you what an assessment involves before you commit to anything.
When replacement makes more sense
We will tell you when a screen is past economic repair, because quoting a repair that fails again in six months helps nobody. Replacement usually wins when damage is widespread, the module batch is unavailable and the supporting structure is tired as well. Water damage is the classic grey area, and we have written a separate guide on repairing versus replacing a water damaged LED screen.
How to get an accurate quote fast
The quality of the quote depends on the quality of what you send. A short video of the fault playing across the screen tells us more than any description. Add a close-up of the affected modules, the brand and pixel pitch if visible, and roughly when the fault started. That is usually enough for a fixed quote the same week.
