1.CPU判定为无电台信号而自动停机当无行同步信号(H.SYNC)或电台识别信号电压或上述电路异常时,一般会导致搜台不停现象,一段时间后,CPU判定为无电台信号而自动停机。2.在预置选台、自动搜索过程中若屏幕出现一闪即失而无“停顿感”的画面时,故障部位多在CPU的电台识别(同步)信号输入电路中;当闪失画面有“停顿感”但节目号不翻转、不增时,故障多在CPU的AFT信号输入电路中;节目号能
1. The CPU determines that there is no station signal and stops automatically. When there is no line synchronization signal (H.SYNC) or station identification signal voltage or the above circuit abnormalities, it will generally cause the station to stop the phenomenon. After a period of time, the CPU determines that there is no station Signal and automatically shut down. 2. In the preset channel selection, automatic search process if the screen flashes and disappears without “pause ” screen, the fault location and more in the CPU radio identification (synchronization) signal input circuit; when the screen disappear There is “stop feeling” but the program number does not flip, do not increase, the fault in the CPU AFT signal input circuit; program number can
