广州雅阁2．3音响单碟cd机通病

修理工

广州本田雅阁2．3音响采用较为实用的双层单碟加长带机．如图1所示，但此机cd部分故障率非常高，常体现为光盘放入几秒钟后又被吐出来此机出现此故障大多有以下两种原因。<br />  一、光盘放入后，托盘电机旋转数圈后，无法读盘自动出舱。此故障大多为机器上盖封闭不严．使激光头物镜被灰尘污染所致，只需清洗物镜即可。如故障仍未排除，更换光头便可彻底排除。光头型号为阿尔派92.5光头。<br />  二、光盘放入后托盘电机后不转．光头又不脏，此时可以参见图2。托盘电机引线经cbl02插座1、3脚至驱动块ba6791 fp的11、12脚，原因多为此间双层线路板过孔断路所致。只需用导线连线既可排除故障。此机无需密码开机，图3为拆机加电图，1脚为十b，9脚为acc．1 1脚为gnd．适合广本多种车型音响加电。 <p>            <img height="252" alt="" src="http://repair.chg168.com/upload_files/article/9/1_20070810100851_jui5juuzjuixjujfmq==.jpg" width="417" border="0" style="border-left-color:#000000;filter:;border-bottom-color:#000000;width:200px;border-top-color:#000000;height:200px;border-right-color:#000000" />   <span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><font face="宋体" size="2"></font></span><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><font face="宋体" size="2"></font></span><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><font face="宋体" size="2"></font></span><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><font face="宋体" size="2"></font></span></p><p><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa">                          <font face="宋体" size="2">图1  广本雅阁2．3音响外观图</font></span></p><p><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa">            <strong><img height="359" alt="" src="http://repair.chg168.com/upload_files/article/9/1_20070810100820_jui5juuzjuixjujfmg==.jpg" width="500" border="0" style="border-left-color:#000000;filter:;border-bottom-color:#000000;border-top-color:#000000;border-right-color:#000000" /></strong></span></p><p><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><font face="宋体" size="2"><strong>               </strong>          图2  广本雅阁2.3音响电路板     </font></span></p><p><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><font face="宋体" size="2">       <img height="325" alt="" src="http://repair.chg168.com/upload_files/article/9/1_20070810100825_jui5juuzjuixjujfmw==.jpg" width="500" border="0" style="border-left-color:#000000;filter:;border-bottom-color:#000000;border-top-color:#000000;border-right-color:#000000" /></font></span></p><p><span style="font-size:8.5pt;color:black;font-family:仿宋_gb2312;letter-spacing:0.1pt;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-bidi-font-family:'times new roman';mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><font face="宋体" size="2">                            图3  广本雅阁2.3音响拆机加电图  </font></span></p>
