Absen A99 Series troubleshooting
The Absen A99 Series problems live-event techs bring to Ask Roadie most (also called A99 outdoor). Pick your symptom, or describe your own in plain words, and get the likeliest fix first, with the manual page when there is one.
Common A99 Series 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 →
A whole cabinet or run of cabinets goes black / disappears in the control software
Likely cause: Perimeter runs are daisy-chained; a single upstream power or data break cascades.
- Step-by-step fixGet the fix →
Brightness or color mismatch between cabinets/modules across the perimeter
Likely cause: Mismatched working mode or gamma between receiving cards is the usual cause of cabinet-to-cabinet brightness steps; unified settings + Save to HW makes it stick.
- Step-by-step fixGet the fix →
Configuring / verifying redundancy (dual power, triple signal)
Likely cause: Redundancy is passive hardware capability; it must be physically looped and switched on in software, and validated by a failover pull-test, or it does nothing when the primary drops.
- Step-by-step fixGet the fix →
Display stays black though powered on (no signal)
Likely cause: LEDs light only when they get both power and a valid data stream; confirming the sender port map and cable continuity restores the picture without touching modules.
- Step-by-step fixGet the fix →
Flicker, scan lines, or banding visible on broadcast camera
Likely cause: Cameras sample the panel; if panel refresh isn't high enough or sections aren't genlocked, the mismatch shows as scan bars on air.
- Step-by-step fixGet the fix →
Handling / positioning pitch-side perimeter boards (player-safety & lifting)
Likely cause: Perimeter boards sit at the field of play; incorrect angle, insufficient ballast, or overweight handling creates a direct injury risk to players and crew.
- Step-by-step fixGet the fix →
Maintaining the outdoor seal / water-ingress concern
Likely cause: The rating only holds if gaskets/glands and the breather valve are intact; the breather prevents the pressure differential that would otherwise pull moisture past the seals.
- Step-by-step fixGet the fix →
One module is black while the rest of the cabinet displays fine
Likely cause: A single dark module is almost always a local power/flat-cable fault or a low PSU rail, not the panel itself - cheapest fixes first.

Setting up an A99 screen from scratch in NovaLCT
Likely cause: Using the vendor config file guarantees correct scan, data group, and driver-IC timing; the two-stage (receiving-card then screen-connection) flow is the required NovaLCT order.
- Step-by-step fixGet the fix →
Spec & planning reference (A99-6.25 vs A99-10)
Likely cause: Correct pitch/refresh/power figures drive processor choice, drop counts, and power distribution when planning a perimeter run.
- Step-by-step fixGet the fix →
Updating firmware / receiving-card program
Likely cause: Perimeter panels are driven by receiving cards; keeping the receiving-card program and controller firmware matched to Absen's current build avoids scan/timing regressions.
