Common Tetra2 errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
Display shows "Base Fan 1 - Blackout" or "Base Fan 2 - Blackout"
Likely cause: Loss of a base fan removes forced cooling; the firmware forces blackout as a thermal-protection measure rather than let the LEDs overheat.

Display shows "EEprom Error"
Likely cause: The EEprom stores fixture settings and calibration; a hardware fault means those cannot be read/written correctly.
- Step-by-step fixGet the fix →
Display shows "Recharge The battery" or "Battery faulty. Replace it."
Likely cause: The display board uses a rechargeable backup cell so you can address/configure with no mains; a flat or dead cell disables battery-powered menu access.

Display shows "Temperature Sensor Error"
Likely cause: The head sensor feeds thermal-shutdown logic; a broken comms link means the fixture cannot protect its LEDs from overheating.

Display shows "Tilt Error 1" or "Tilt Error 2" after reset; head not at default position
Likely cause: Tilt homing relies on a magnet + Hall sensor to find zero; if indexing fails the controller cannot establish the default position and flags the error.

Fixture reset or special function (e.g. RGBW/CMY mode switch, DMX input select) will not trigger from the console
Likely cause: Robe gates destructive/override commands behind a closed-shutter + dwell-time interlock so they cannot fire accidentally during a show.

How to update firmware / device software on the Tetra 2
Likely cause: Robe Uploader is the manufacturer tool; RDM/Ethernet gives automated flashing, DSU is the fallback bootloader path for non-RDM fixtures.
- Step-by-step fixGet the fix →
Individual pixels / pixel patterns not responding to DMX
Likely cause: The colour-mix control channel arbitrates between global colour and per-pixel data; at low values global mixing overrides pixels, and Modes 1-2 simply lack pixel channels.

Yellow "Clean Air Filters" warning / air-filter cleaning icon on screen
Likely cause: The filter timer is a maintenance reminder; clearing dust restores base cooling airflow and resetting the counter clears the warning.
- Step-by-step fixGet the fix →
Zoom uneven / optical module needs removal or reseating (service)
Likely cause: The zoom modules are driven by lead screws into stepper motors; correct re-engagement of pins/screws and the securing screws is required for smooth, safe zoom travel.
