由于金泰克 KT-D8320数字机性价比高,在社会上有一定的拥有量。该机开关电源以 IL0380R 为核心元件,电路简捷、功耗低,但有时也会发生故障,现将其常见故障归纳整理,供维修者参考(金泰克 KT-D8320数字机开关电源局部电路图如图1所示)[例1]故障现象:开机后面板无任何显示,无图无声。分析与检修:打开机盖,检查保险管已熔断发黑,此现象说明电源的供电电路有严重的故障。不能急于更换保险、供电,应对电源输入电路进行细致的检查从220 V 交流电源输入端开始逐个元件仔细
As the Golden Tektronix KT-D8320 digital machine cost-effective, in the community have a certain amount of ownership. The machine switching power supply to IL0380R as the core components, the circuit is simple, low power consumption, but sometimes failure, now its common fault induction finishing, reference for maintenance (Kim Tektronix KT-D8320 digital switching power supply partial circuit shown in Figure 1) [Example 1] Symptom: After power on the panel without any display, no picture no sound. Analysis and Maintenance: Open the cover, check the fuse has blown black, this phenomenon shows that the power supply circuit has a serious fault. Can not hurry to replace the insurance, power supply, the power input circuit to conduct a detailed examination From the 220 V AC power input one by one carefully
