含义
显示屏通讯故障——主控板与显示面板之间的数据通讯中断。
常见原因
- 显示屏排线松动或接触不良
- 排线在门体铰链处长期弯折断裂
- 显示屏控制板受潮短路
- 主控板通讯接口电路故障
- 显示屏连接端子氧化导致信号失真
- 冰箱门体开关时排线被反复拉伸受损
自助排查
- 断电后重新插拔显示屏排线两端
- 检查排线在门铰链处是否有磨损或断裂
- 用酒精清洁排线金手指和插座触点
- 观察显示屏是否部分显示正常（局部故障也可能是排线断线）
- 若排线完好仍无法通讯，需更换显示屏板或主控板
English
Meaning
Display communication failure — data transmission between the main control board and the display panel is interrupted.
Common Causes
- Loose or poor contact of the display ribbon cable
- Ribbon cable broken from repeated bending at the door hinge
- Display control board shorted due to moisture
- Faulty communication interface circuit on the mainboard
- Oxidized display connector pins causing signal distortion
- Ribbon cable repeatedly stressed from door opening and closing
Self-Check Steps
- Power off and reseat the display ribbon cable connectors at both ends
- Inspect the ribbon cable at the door hinge for wear or breakage
- Clean the ribbon cable contacts and socket pins with alcohol
- Observe if parts of the display still work — partial failure often indicates a broken trace in the ribbon cable
- If the cable is intact but communication still fails, replace the display board or main control board
