Control panel interface PCB
Control panel functions, keyboard function ,trackball function ,
footswitch function ,led function
Image memory PCBA1 Main system memory
Control panel interface PCB在触摸屏下部，键盘及触摸屏输入都连接到这块线路板上。
例如：键盘及控制面板无法输入，是这块电路板出现故障。
设备起动时，前面驱动器先工作读一号盘1秒"21秒，指示灯亮。后驱动器读2号盘
22秒"56秒，指示灯亮。
驱动器位置有两种位置分别为：在设备后盖部位或在设备整体推出后右侧位。
更换电路板注意事项：1.对照老板子芯片与新电路板芯片是否缺少。
2.注意跳基线是否相同，不同则以老电路板为准。
