Hyundai 21K8-42601 Controller
 |
Hyundai 21K8‑42601 is a monitor/display cluster assembly used in HX series excavators (e.g., HX145LCR, HX235LCR). Common failure points for this class of industrial display controllers include burnt or damaged ICs on the main board, loose or corroded connector pins, and degraded LCD panel backlight LEDs. First‑check steps: verify that the power supply to the cluster is within spec (12 V DC, correct polarity), inspect all connectors for secure seating and signs of corrosion, and examine the display panel for flickering, dead pixels, or backlight failure; if a diagnostic code is available on the controller’s interface, review it for specific fault indications.[oss-gpt-20b] |
