2.B系列产品与HPCHD系列产品电路比较B系列与HP、CHD系列电路差异:(1)行扫描电路、开关电源、CPU组件控制系统(程序虽不同,但输出控制信号相似)、数字处理板、会聚电路、视频放大电路等电路工作方式相同,电路组成也基本相同。CHD与B系列数字板结构及电路组成相同,但数字板与主板相连的两个插座传递的信号是不同的。①B系列插座XP02传递CPU组件对数字板控制
2.B series products and HPCHD series circuit comparison B series and HP, CHD series circuit differences: (1) line scan circuit, switching power supply, CPU components control system (although the procedure is different, but the output control signal is similar), digital processing board , Convergence circuit, video amplifier circuits and other circuits work the same way, the circuit is also basically the same composition. CHD and B series digital board structure and circuit composition of the same, but the digital board and the motherboard connected to the two sockets to pass the signal is different. ① B series socket XP02 transfer CPU components on the digital board control
