一台康佳T5429E彩电,自动搜索时可搜索到电视信号,但不变号、不存台。该机采用TA7680+TA7698两片机心,CPU为ST6367。仔细观察该机除了不存台故障外,而且行幅稍窄,不到边。用户主要反映电视收不到台,所以首先检查中放电路,图像中周和AFT中周正常,微处理器电台识别同步信号和AFT?
A Konka T5429E color TV, automatic search can search for television signals, but no change in number, no depository. The machine uses two TA7680 + TA7698 movement, CPU is ST6367. Careful observation of the aircraft in addition to the absence of failure, but the line width is slightly narrower, less than the edge. Users mainly reflect the TV does not receive the station, so first check the discharge circuit, the image week and AFT week normal, microprocessor radio identify synchronization signal and AFT?
