Common S3 Screen Management 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 →
DisplayPort 1.2 input suddenly stops displaying until chassis reset
Likely cause: The DisplayID negotiation path can hang the DP receiver; forcing a known EDID removes the problematic negotiation and a soft reset re-arms the input.
- Step-by-step fixGet the fix →
Fans loud / thermal concern / suspected overheating
Likely cause: The processor throttles fans to hold junction temps; sustained 100% with no error just means it is working hard, whereas a Dashboard thermal flag indicates a real airflow or card issue.
- Step-by-step fixGet the fix →
Firmware / Toolset version mismatch — features missing or unit refuses connection after update
Likely cause: Toolset and firmware negotiate a feature/protocol handshake; a version gap makes the unit reject the connection or hide features, and mismatched firmware across linked units breaks ganging.
- Step-by-step fixGet the fix →
HDCP-protected source shows black / no image on output
Likely cause: HDCP is enforced link-by-link; a single non-HDCP card or display in the chain blanks the protected signal, so the fix is to keep the whole path HDCP-capable.

Input shows no signal / input connector LED not green
Likely cause: The input LED is the fastest sync indicator; green = the card locked to a valid raster.
- Step-by-step fixGet the fix →
Linked / ganged chassis not syncing or link input unstable between units
Likely cause: Link cards distribute uncompressed video between chassis over fiber; a connector not locked fully gives intermittent optical contact and random link dropouts that mimic a card fault.
- Step-by-step fixGet the fix →
Power redundancy not protecting the unit / drops on a single supply failure
Likely cause: True redundancy only exists when each PSU is powered from a separate feed; a single shared circuit or an un-populated second bay means a fault still drops the whole box.
- Step-by-step fixGet the fix →
Toolset (EM software) cannot find or connect to the unit on the network
Likely cause: EM Toolset discovers units by broadcast on the shared subnet; a DHCP/static mismatch or a firewall blocking discovery is the usual reason a healthy unit never appears.
- Step-by-step fixGet the fix →
Tri-Combo / SDI input will not acquire from an Atomos Shogun or similar 6G/12G-SDI source
Likely cause: The Tri-Combo card validates SDI CRC per SMPTE ST-2081/2082; a non-compliant CRC stream is rejected, so dropping to a compliant 3G path lets the card lock.
- Step-by-step fixGet the fix →
Unit will not fully boot / hangs on startup
Likely cause: A corrupt config or OS state blocks boot; SEL+ESC-at-power forces the recovery menu and clears settings back to defaults so the box can start clean.
