Brother CT‑1400 is a 12″ monochrome CRT monitor designed for use with vintage word processors and early PC video standards (MDA, CGA, EGA). Common failure modes in this class include cathode‑ray tube degradation (burn‑in or phosphor fade), power supply capacitor failure leading to flicker or no display, and loose or corroded 9‑pin connector contacts. Initial diagnostics should verify the monitor’s 12V/5V DC input rails with a multimeter, inspect the CRT for visible burn marks or bulging capacitors, and test the 9‑pin data cable continuity before connecting to a compatible video source.[oss-gpt-20b] |
