Common Nova M3 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.

Novastar MX40 Pro specs (I/O, capacity)
Likely cause: Manufacturer-published spec.
- Step-by-step fixGet the fix →
How to check current firmware / hardware version
Likely cause: Hardware Information reports the actual loaded versions per card, so you can spot a mismatched or un-updated receiver that would otherwise behave inconsistently.

How to update sending-card / receiving-card firmware in NovaLCT
Likely cause: NovaLCT flashes both the sending card and receiver cards from the advanced menu; loading the model-matched firmware and verifying the reported version prevents a half-updated, mismatched control chain.
- Step-by-step fixGet the fix →
MCTRL300 / M3 controller shows no image from an HDMI source
Likely cause: The M3-series controller only locks to single-link DVI at a matched resolution; an unmatched or HDMI-only feed gives no/incorrect image until converted and resolution-matched.
- Step-by-step fixGet the fix →
Screen flickers or shows scan lines on camera
Likely cause: A higher module refresh rate raises the PWM frequency above the camera shutter and human flicker threshold, stabilizing the image; matching it across cabinets prevents per-panel brightness-efficiency differences.
- Step-by-step fixGet the fix →
Settings revert / are lost after a power cycle
Likely cause: NovaLCT 'Send' only pushes settings to volatile memory; 'Save to Hardware' writes them to the receiver card flash, so skipping that step loses everything on power cycle.
- Step-by-step fixGet the fix →
Cabinets show different brightness or color from each other
Likely cause: Brightness/color uniformity depends on identical refresh, gamma, working mode and calibration state across cabinets; equalizing those in NovaLCT (or matching calibration coefficients) removes the visible blocks and seams.
- Step-by-step fixGet the fix →
Whole cabinet blank while others show image
Likely cause: A single dark cabinet is almost always a broken link or an unconfigured/failed receiver in that node; verifying the LED state and re-sending the receiver config restores communication without reconfiguring the whole wall.
