Daktronics OP-1145-0120 PC-156233 REV 3 Circuit
 |
Daktronics OP‑1145‑0120 PC‑156233 REV 3 is a high‑power LED driver/control board used in scoreboard and display systems. Common failure points for this class include power supply decoupling capacitors, MOSFETs on the output stage, and I/O trace contamination or solder joint fatigue. Begin by verifying that the input voltage matches spec and checking for any blown fuses; inspect the board for burn marks or cracked components, then test the output driver ICs with a multimeter and oscilloscope for correct gate drive signals before proceeding to component replacement.[oss-gpt-20b] |
