故障现象:屏幕有规则清晰的黑白条,无伴音。故障分析:这是行频不同步,并影响μPC1423CA内的行一致性(实则为电台识别信号)检测电路工
Symptoms: the screen has a clear black and white stripes, no sound. Failure Analysis: This is the line frequency is not synchronized, and affect the consistency within the μPC1423CA line (in fact, the radio signal recognition) detection circuit
