Heidenhain BE 411 monitor
 |
The Heidenhain BE 411 is a 12‑inch monochrome CRT display mounted in TNC 155/155B CNC controllers, typically used to show spindle status and tool data. Common failures include loss of image due to backlight or phosphor degradation, tube burnout causing flicker or complete blackout, power supply voltage spikes damaging the monitor’s internal electronics, and loose D‑sub connections leading to intermittent display. First‑check diagnostics: verify 85–240 V AC input and monitor output voltage levels; inspect the D‑sub connector for bent pins or corrosion; visually examine the CRT for burn marks or cracked glass; review any error codes from the TNC controller that reference “Monitor” or “Display.”[oss-gpt-20b] |
