Richardson Electronics 110-240 LI19112CM-FSAY Monitor

The Richardson Electronics LI19112CM‑FSAY is a 110–240 V industrial monitor used in control panels and instrumentation displays. Common failure modes for this class include power supply board faults (transformer or rectifier), backlight or panel degradation, signal input loss from the video interface, and firmware corruption that can trigger blank or flickering screens. First‑check diagnostics should verify proper AC voltage at the inlet, confirm regulated DC output on the monitor’s power rails, inspect all connector pins for corrosion or loose contacts, test a known good video source to rule out upstream issues, and review any diagnostic LEDs or error codes displayed by the unit.[oss-gpt-20b]
