The C5470NS is a 14‑inch color CRT monitor originally mounted on Mazak and Mitsubishi CNC/automation control panels (Mazatrol M2/T2/M3/T3). Common failure modes include CRT phosphor burn‑out or tube failure, power supply board faults (especially the high‑voltage regulator), backlight flicker from aging capacitors, and signal line degradation causing distorted images. First‑check diagnostics: verify that the monitor receives correct 12 V/5 V DC rails and proper high‑voltage output; inspect the CRT for visible burn marks or cracked glass; test the video input/output with a known good controller to rule out upstream signal issues.[oss-gpt-20b] |
