Abstract: <正> 以微处理器M50436—560SP和存储器M58655P组成的遥控彩电有:牡丹54C4A、49C]1型;金星C4717、C515型;飞跃54C2Y21—1、47C2Y2—6、51C2Y21—2、49C2Y21—1型;凯歌4C4701—4型;昆仑S541型;上海Z654—4A、Z665—5A型;北京8316型;孔雀KQ54型;福日HFC—14(?)5、2025、2125型等。该类遥控彩电,在二次开机后,微处理器第⑨脚便由低电平(0V)变为高电平(5V),输出开机指令,使驱动三极管V938导通,二次开机继电器K901吸合,整机得电开始正常工作。该类遥控彩电,一旦出现开机失灵故障,即“三无”故障时,可测量微处理器第⑨
