Heidenhain B411B monitor
 |
Heidenhain B411B is a 12‑inch CRT/LCD display module used on TNC series CNC controllers, providing the operator interface and status feedback. Common failures include fading or dimming of the screen (often due to aging phosphors or power supply ripple), intermittent signal loss from the D‑sub connector, and backlight failure in LCD conversions. For troubleshooting, first verify the controller’s 24 V DC rail and ensure it is within spec; then check the D‑sub cable continuity and look for loose pins or corrosion. Finally inspect the display board for visible damage (burnt components, cracked capacitors) and review any error codes displayed on the host controller before proceeding with component replacement.[oss-gpt-20b] |
