汽车音响出现故障该如何进行处理?

来源:http://www.jnrunao.com/ 日期:2020-09-17 发布人:runao
汽车音响出了故障,应到专门的汽车音响维修站进行全面检查,才能鉴定病因、对症下药,绝非“街头诊所”所能胜任。汽车音响不同于家用音响,电路设计也比家用音响复杂,非的维修站甚至不知如何拆卸,更不知专用拆卸工具为何物。
If there is a problem with the car stereo, we should go to a special car stereo maintenance station for a comprehensive inspection, so as to identify the cause of the disease and prescribe the right medicine to the case. Car audio is different from home audio, and its circuit design is also more complex than that of home audio. Non professional maintenance stations even don't know how to disassemble, let alone what special disassembly tools are.
部分车主有病乱投医,找一些个人或街头小店修理,其结果是原来的问题没有修好又产生了新的故障;有的使用二手拆机件,价格便宜但无法保证质量;有的使用非专用工具,将车内的饰板撬坏———将聋子治成了哑巴。
Some car owners went to the doctor when they were ill and went to some individual or street shop for repair. As a result, the original problems were not repaired and new faults were produced. Some used second-hand dismantling parts, which were cheap but could not guarantee the quality. Some used non special tools to pry the interior trim panel out of the car, which turned the deaf into mute.
一、维修音响要做“全身检查”
1、 "Whole body examination" should be done for the maintenance of stereo
维修汽车音响不仅要检查音响本身的故障,还要全面检查车辆本身的线路,排除车辆对音响的影响。
Maintenance of car audio not only needs to check the fault of the audio itself, but also comprehensively check the circuit of the vehicle itself to eliminate the impact of the vehicle on the audio.
曾有一辆汽车音响的收音和卡带部分工作正常,但CD不工作。打开主机检查发现CD控制系统烧毁;继续检查CD连接线,发现11条线中有6条相互短路;进而发现造成故障的根本原因是安装地胶门边条固定螺丝钉时将CD线打穿,造成短路。
Once, the radio and cassette of a car stereo worked normally, but the CD did not work. Open the host machine to check and find that the CD control system is burnt out; continue to check the CD connecting wires, and find that 6 of the 11 lines are short circuited with each other; and then it is found that the root cause of the fault is to break through the CD cable when installing the fixing screws of the side strip of the floor rubber door, resulting in short circuit.
通过以上故障不难看出,只对音响主机维修是不够的,还需对汽车电路部分进行检修,才能彻底解决故障。
It is not difficult to see from the above faults that it is not enough to only repair the audio head unit, but also need to overhaul the automobile circuit to completely solve the fault.
二、维修音响要达“原厂标准”
2、 The maintenance of audio should meet the "original factory standard"
维修汽车音响的技术含量是很高的,不能只是“修响”就算“修好”,还要确认是否达到*状态或厂家规定标准。没有测试仪器及专用设备和工具,很难将音响恢复到原厂标准。
The technical content of car audio maintenance is very high. We should not only "repair" even "repair", but also confirm whether it meets the * status or the manufacturer's specified standards. Without testing instruments and special equipment and tools, it is difficult to restore the sound to the original factory standard.
汽车音响多采取高度集成的芯片、电路板,在很小的体积内包括多种功能———麻雀小但五脏全,修理人员需要具有一定的汽车音响技术知识和维修经验。成立汽车音响维修站更非简单的事情,前期购买仪器设备、维修资料、零配件,进行人员培训、积累经验的投入也巨大;得到厂商授权,才能进一步获得各款汽车音响的技术资料和原厂配件,才能保证维修质量。
Car audio mostly adopts highly integrated chip and circuit board. In a very small volume, it includes multiple functions -- small sparrow but full of five internal organs. The repair personnel need to have certain technical knowledge and maintenance experience of automobile audio. It is more difficult to set up an automobile audio maintenance station. In the early stage, the investment in purchasing instruments and equipment, maintenance data and spare parts, personnel training and experience accumulation is also huge. Only with the authorization of the manufacturer, can we further obtain the technical data and original accessories of various types of automobile audio, and guarantee the maintenance quality.
