Technical Service & Repair Protocol

At Mangal Sen and Sons, we maintain a dedicated laboratory for the repair of 3D Hologram Fans, Gobo Projectors, and high-brightness LED panels. Our service hub is staffed by engineers who understand the intricate physics of Persistence of Vision and Dichroic Optics.

1. Remote Diagnosis

Before shipping hardware, we conduct a video-call diagnosis to identify if the issue is software-related, such as Wi-Fi connectivity glitches or CMS errors.

2. Inward Logistics

If hardware repair is required, clients can ship the unit to our Delhi Service Hub. We recommend using the original protective flight cases for 100cm fans to prevent transit damage.

3. Component-Level Repair

We specialize in LED blade replacement, motherboard soldering, and optical lens recalibration.

4. Quality Control

Every repaired unit undergoes a 24-hour "Burn-in Test" to ensure thermal stability and pixel integrity before being shipped back.
