Komatsu PC400-7 7835-12-2002 Monitor
 |
The Komatsu PC400‑7 7835‑12‑2002 is a monitor display panel that houses the operator’s control interface and gauge cluster for the excavator. Common failure points include dead or flickering LCD segments due to burned‑out backlight LEDs, loose or corroded connector pins on the harness, and power supply voltage drops from degraded onboard regulators. First‑check steps: verify 12 V DC input at the panel’s rear connector; inspect all wiring for continuity and corrosion; review any diagnostic fault codes displayed (e.g., “E‑01” for display failure) before proceeding to replace LEDs or re‑seat connectors.[oss-gpt-20b] |
