The Allen‑Bradley FC15 A/B is a 15‑inch industrial flat‑panel LCD monitor used in factory automation panels and control rooms. Common failure modes for this model include backlight LED burnout, power supply board faults (especially the DC/DC converter), capacitive touch panel degradation, and display driver IC failures that cause flickering or no image. Initial checks should verify 100–240 V input voltage, inspect the main power board for burnt components or loose solder joints, and confirm the monitor’s internal diagnostic LED status; if the display is blank but LEDs light, test the backlight driver and capacitors. If the screen shows a static image or flicker, perform a short‑circuit test on the LCD panel and examine the display controller board for damaged traces or blown resistors.[oss-gpt-20b] |
