What we repair
- Dead or flickering modules, single tiles or whole rows, replaced with matched modules so colour stays uniform.
- Receiving card and sending card faults on NovaStar, Huidu, Linsn and Colorlight controllers.
- Power supply failures, the most common cause of a dark section.
- Data cable and hub board faults that show as frozen or garbled sections.
- Colour and brightness calibration after module replacement or years of use.
- Controller and CMS problems, including content not playing, wrong resolution and scheduling.
How a repair call works
- WhatsApp a photo or video of the fault to +91 72048 08334 with the wall size and brand if you know it.
- We diagnose remotely where possible. PxlOS Signal reads NovaStar, Huidu and Linsn controllers over the network, so many faults are located before an engineer leaves.
- An engineer reaches any Bengaluru site within 24 hours, usually the same day, with the likely spares in the van.
- You get a written fault report and a fixed quote before any part is fitted.
If the wall is still inside its 2-year warranty, most of these calls cost nothing; what is normal in year one and what counts as a claim is in the first-year warranty and faults guide.
Repair pricing: what decides it
The price depends on the fault, the part, the pixel pitch and the size of the wall. Typical jobs and time on site:
| Job | Time on site |
|---|---|
| Site visit and diagnosis, Bengaluru (waived if you proceed with the repair) | 1 hour |
| Module replacement, indoor P2.5 to P4 | 15 minutes per module |
| Power supply replacement | 30 minutes |
| Receiving card replacement | 30 minutes |
| Full recalibration | Half a day |
Every repair gets a fixed quote on the written fault report before any part is fitted. GST extra. For the exact price, WhatsApp the fault and wall size to +91 72048 08334.
AMC plans
An annual maintenance contract covers scheduled inspection, cleaning, calibration, priority 24-hour response and discounted spares. Plans are priced by wall size; WhatsApp us your wall size for the exact AMC price. Walls bought from PixelSpot carry a 2-year pixel-to-pixel onsite warranty first, so AMC starts in year three. What years two to five look like, from the spare box to the yearly recalibration, is in LED wall after installation: years 2 to 5.
Walls we did not sell
Yes, we service them. Bring the controller model or a photo of the back of a module and we will tell you on WhatsApp whether we stock the spares. Most Chinese-module walls sold in Bangalore use parts we keep in stock.
