Daktronics Inc PC-117359 Circuit Board

Daktronics PC‑117359 is a high‑current LED driver circuit board used in scoreboard and display control systems. Common failures on this model include burnt or failed MOSFETs/IGBTs, degraded gate drivers, and capacitor leakage due to heat cycling; power supply decoupling can also be compromised by aging electrolytics. First‑check diagnostics: verify the input voltage rail (typically 120 V AC or 48 V DC) with a multimeter, inspect for visible burn marks or swollen capacitors on the board, and test the output current path with an isolation transformer to confirm proper LED drive operation.[oss-gpt-20b] Post Comment
