长虹 CN—18机心的微处理器和小信号解码电路采用超级芯片 TMP8803或者 TMP8829。长虹公司采用CN—18机心生产的彩电主要有:SF1498E、SF2191E、SF2518E、SF2170E、PF2591E、SF2970E、PF2918E 等型号。下面介绍该机心 I~2C 总线的调整方法与数据。1.维修模式的进入方法将电视机声音调整到最小,按住本机 K18D 遥控器上“静音”键的同时,按电视机面板上的“菜单”键,屏幕上显示字符“S”,表示电视机进入了“维修模式”。2.I~2C 总线数据调整方法进入“维修模式”后,按“节目增/减”键对要进行调整的项目进行选择,项目选定后,按“音量加/减”键对选定的项目进行调整。
Changhong CN-18 movement microprocessors and small signal decoding circuit using super chip TMP8803 or TMP8829. Changhong color TV using CN-18 movement production are: SF1498E, SF2191E, SF2518E, SF2170E, PF2591E, SF2970E, PF2918E and other models. The following describes the movement of the I ~ 2C bus adjustment methods and data. 1. Enter the maintenance mode to adjust the TV sound to a minimum, press and hold the machine “Mute” button on the K18D remote control at the same time, press the “menu” button on the TV panel, the screen displays the character “S”, said The TV went into “maintenance mode”. 2.I ~ 2C bus data adjustment method After entering the “maintenance mode”, press the “program up / down” button to select the items to be adjusted, after the project is selected, press the “volume plus / minus” button on the selected Project adjustments.
