Daktronics Inc. OP-1192-0011 led indicator board

The Daktronics OP‑1192‑0011 is a 16‑output outdoor LED driver board that powers scoreboard displays from a 24 VDC switching supply and provides status indication via its LED array. Common failure modes include power supply degradation (voltage drop or ripple), burned or open LEDs, and failure of internal MOSFETs or protection diodes due to overcurrent or thermal cycling. First‑check diagnostics: verify the 24 VDC input is within spec; inspect each LED for continuity and visible damage; and check the driver’s output transistors and associated heat sinks for overheating or component failure.[oss-gpt-20b] Post Comment
