例1:康力CE-6478B彩电,电源指示灯亮,遥控开机后无反应。分析与检修:该机中放、行、场小信号电路采用TDA8361集成块,CPU为M37211M2-011SP。遥控关机电路是通过三极管控制行推动级的(为25V供电)。在遥控关机状态下,切断行推动级供电电源,迫使行电路停止工作。在开机状态下,恢复
Example 1: Compaq CE-6478B color TV, power indicator light, remote boot no response. Analysis and Overhaul: The aircraft put, line, field small signal circuit using TDA8361 manifold, CPU M37211M2-011SP. Remote shutdown circuit through the transistor control line to promote the level (for 25V power supply). In the remote off state, cut off the line to promote the level of power supply, forcing the circuit to stop working. In the boot state, recovery
