The OP‑1192‑0347 is a Daktronics circuit board used in 12″ RED 7‑segment LED scoreboards, typically mounted on the display module and interfaced with the scoreboard controller. Common failure points on this class of boards include burnt or cracked surface‑mount components (especially power MOSFETs and voltage regulator ICs), degraded solder joints at the LED driver pads, and shorted traces caused by moisture ingress or mechanical stress. Initial diagnostics should verify that the board receives the correct supply voltages from the controller (12 VDC ±10 % and 5 VDC for logic), inspect all component leads and solder joints for visible damage, and check the LED outputs with a multimeter or oscilloscope to confirm proper drive signals before proceeding to more detailed IC testing.[oss-gpt-20b]
