Anatomy of an LED Panel
Understanding the physical components of your LED panels helps with troubleshooting, maintenance, and replacement requests.
For a detailed visual guide to LED panel components, visit the Hardware Support section on the Vū support site.
Key Components
Modules — The individual LED tiles that make up a panel. Each module contains a grid of LED pixels and can be replaced independently if damaged.
Cabinet/Frame — The structural housing that holds multiple modules together. Cabinets connect to each other to build the full wall.
Receiver Card — The electronics card inside each cabinet that receives the video signal and distributes it to the modules.
Sending Card — Installed in the media server, the sending card outputs the video signal to the receiver cards via fiber or Ethernet cable.
Power Supply — Each cabinet has one or more power supplies. Power supplies can fail independently.
Data Cable — Connects cabinets in a daisy-chain from the sending card.
Common Issues
| Symptom | Likely cause |
|---|---|
| One module darker than others | Failing power supply or module |
| Horizontal line of dead pixels | Failing receiver card |
| Color shift on one cabinet | Calibration drift — needs recalibration |
| Entire cabinet dark | Power supply failure or loose data cable |
| Random flickering | Loose data connection between cabinets |
