功放机在组建家庭影院当中有功不可没的功劳。一旦功放机“罢工”,将会导致整套套材的“休息”,笔者检修音响器材多年,特撰一功放机的检修实例以飨读者。例1 华声2188功放机使用一段时间,机内突然冒烟,继而无声。电源指示灯与中点保护指示灯不亮。分析检修:根据故障现象确定故障部位在电源电路,图1是该机的电源电路原理图,先查电源变压器线圈、
Power amplifier machine in the formation of home theater which credit. Once the power amplifier “strike”, will lead to the entire set of “rest”, I repair audio equipment for many years, especially a power amplifier repair examples to readers. Example 1 Huasheng 2188 amplifier for a period of time, the machine suddenly smoke, and then silent. Power indicator and midpoint protection indicator does not light. Analysis and maintenance: According to the fault phenomenon to determine the fault location in the power circuit, Figure 1 is the power supply circuit diagram of the machine, first check the power transformer coil,
