液晶显示器维修技巧（ 8页）

1、 液晶显示器维修技巧以下是根据我们日常的维修总结的一些维修思路： 1.显示器整机无电这是一个应该说是非常简单的故障，一般的液晶显示器分机内电源和机外电源两种，机外的常见一些。不论那种电源，它的结构比crt显示器的电源简单多了，易损的一般是一些小元件，象保险管、输入电感、开关管、稳压二极管等。比较少见的故障是由主板cpu引起的电源不启动，这部分其实原理也比较简单，就是通过键控板到cpu，再通过cpu输出一个控制信号驱动电源变换集成电路工作。 2.显示屏亮一下就不亮了，但是电源指示灯常亮。这种问题一般是高压异常造成的，是保护电路动作了，在这种情况下，一般液晶屏上是有显示的，看的方法是“斜视”。检修

2、的要点是对比修理法。因为，现在的液晶显示器的高压板的设计一般都是对称的设计，而两边都坏的可能基本上没有。一般老机容易出问题的是升压变压器和灯管，新机的保护电路和工艺问题比较的多。 3.屏幕亮线或者是暗线这种问题，一般是液晶屏的故障。亮线故障一般是连接液晶屏本体的排线出了问题暗线一般是屏的本体有漏电，以上两种问题基本上就是给机器判了死刑了，没有维修价值的，因为一块屏的价格太高了。 4.花屏或者是白屏这种问题一般是屏的驱动电压出了问题，如果是屏的驱动电路在主板，那么应该是主板的故障，如果屏的驱动电路在液晶屏上，一般情况下屏就应该换了，维修的风险很大的。 5.偏色故障一般可以进入维修调整模式进行调整

3、。 6.其它相对少见的故障干扰：在不同的工作模式下，液晶显示器有可能出现一些干扰，大部分是正常现象，有少数是电路上带来的。因为，液晶显示器的特殊生产工艺，造成了只有在标准的工作模式下检测到的问题才能够算是故障。 柳细兴 编写2006年7月17日 液晶显示器分四个部分： 1.电源部分：该部分的维修最简单，也很常见，维修方法普通，元件普通。 2.高压板：其实就是一个电子整流器，麻烦的是专用的升压变压器和控制集成电路。一般是电源输入12V直接供电，另外一个5V来自主板，还有一个亮度控制电压，一部分机器有省电控制，来自CPU，就是一个高低电平控制。 3.信号转换板主板：主要有3个部分，CPU、电源转换

4、、输入信号处理集成电路，维修方法和VCD的主板基本一样的（我觉得），易损件是贴片元件电容易漏电、板子易漏电等，少见的是存储器数据丢失、信号处理集成电路损坏等。 4.最有价值的维修部分就是它了液晶屏，当然，难度最大，也相当危险。对维修技术要求很高的。我记得网上有关于液晶屏的拆卸，大家可以去看看。一般情况下，如果是亮、暗线等问题，建议各位不要修了，风险太大，问题一般是驱动集成电路局部损坏、连接排线接触不良等等。 可以维修的故障是白屏（如果修过液晶显示器的朋友，应该知道的，这种问题不是主板就是屏的问题），而且，成功率是比较高的。具体的原理我不太清楚了，但是，大家可以想一想，连接到屏的线只有那么几根，

5、远远不是1024X768，为什么，就因为驱动液晶屏的电路是厂家直接做好的，就在液晶屏背后。 另外一个有点希望维修的就是灯管，大家也清楚，灯管的寿命应该不是厂家宣传的那么长，而且比较好换。 好了，我先说说，抛砖引玉嘛，对于具体的问题，欢迎各位交流。再说一遍，小心为妙，风险有时候可能比收益更大。显示器模糊的原因与处理屏幕显示模糊是各种显示器常见故障之一，其产生原因主要有三个方面： 一是运输过程中或使用中受到震动而使FBT（行输出变压器）的聚焦电位器松动或移位，致使加到CRT中的聚焦电压变化（偏离工厂调试好的最佳电压值），造成屏幕模糊二是使用环境湿度大，使CRT尾座板上聚焦引脚的放电环（半圆球）产生

6、锈蚀，在CRT刚通电时出现模糊现象；三是CRT管内因制造工艺或CRT锥体玻壳内有杂物而使聚焦（focuse）极与加速极（G2）间产生静电积尘，形成极电阻而使屏幕出现严重的模糊现象。怎样根据屏幕模糊的现象来判断是何种原因引起的呢？首先从屏幕模糊的程度来看，若模糊现象较轻，仅仅是字符轮廓变粗，而字迹依然能识别，大多属第一种原因所引起；若字符大面积严重模糊，屏幕一片白色光晕，字符已无法辨认且调FBT上的聚焦电位器时屏幕亮度随之变化，则属第三种原因所为；如果CRT刚开机时模糊，随着时间的延长，屏幕字符越来越清晰，这通常为第二种原因所造成。弄清了屏幕模糊的原因，如何根据故障现象来排除故障呢？对于第一种情

7、况，打开机盖，微调FBT中的聚焦（focuse）电位器即可排除故障。至于尾板上聚焦引脚放电环锈蚀的处理，一般使用无水酒精清洗放电环及尾座上各电极插头和插座，如放电环锈蚀严重时，可更换尾座部件。第三种原因引起的屏幕模糊的处理方法是：取下CRT尾座板，将CRT上高压帽中24KV高压用万用表笔线（最好使用绝缘性能好些的数字万用表）引到CRT聚焦板插座中，打开显示器交流电源，用一接地的表笔线对加速极（G2）插头瞬间放电23次（最好将CRT上G2插头用一外加保护套管短线引出来，对引出线进行对地瞬间放电作业）。一般经过23次放电过程便能使聚焦（focuse）与加速极（G2）两电极之间的尘埃极电阻击穿。恢复

8、原电路后，观察屏幕字符或图文显示的清晰程度，必要时适当调一下FBT上的聚焦电位器就能使模糊故障排除。这种方法人们常称“打Acking法”，操作中因涉及到高电压，应谨慎从事，切记保护人身和设备的安全。需要说明的是，上述屏幕显示模糊故障，并不包括那些诸如加速极（G2）电压调整不当，亮度、对比度电位器调节位置不合适等引起的屏幕失调，看上去似乎有一层雾朦朦之感觉的情况在内。对于IBM 2248G03、EnvisionD350等显示器，用橡皮榔头对准CRT屏幕正中部位轻轻击打几次，有五成把握能排除这类显示器的模糊故障，这不失为修理显示器模糊故障捷径之路。在电脑发生故障时，机器响铃不断。这时，如果你是一位

9、高手，也许可以根据经验判断出故障所在，若根据经验无法判断，或者你对硬件设备一无所知，这时只有去请教专业人员了。笔者由于一台电脑出现故障，开机后只有机器报错的响铃，找不到故障点，只好上网去查询PC机开机自检响铃代码的含义，最终依据代码准确查找出故障所在部位并将其排除。好东西不敢私藏，特向大家推荐，希望你也能据此准确地判断出故障所在，当一回高手。本文以较常见的两种BIOS（AMI BIOS和Award BIOS）的电脑为例，介绍开机自检响铃代码的具体含义（关于电脑使用的BIOS型号可从BIOS芯片上或者从开机自检的信息中看到，如看到AMI的字样则为AMI BIOS；如看到Award字样则为Awar

14、示面板的X、Y电极引出数据线(X电极简称为背电极，Y电极简称为段电极)，即可开始检测。我们知道液晶显示屏的段电极与显示模块输出驱动极之间，是由导电橡胶来连接的。这一点与我们常见的计算器、电子表的笔划显示屏的连接方式是相同的。检查显示屏的简单方法：用一根普通的电线，将其中一根一头的绝缘外皮剥去一小段，然后将另一端在台灯(其他家用电器也可以)的电源线上绕几圈，这样该电线中就会感应产生出微弱的交流电压，虽然这个感应电压的内阻很大，且只具有50Hz的交流感应电动势，它对一般家用电器来说没什么作用，但用于驱动液晶显示器件却正好适用。用左手捏住液晶显示面板的背电极引出线或用金属探针接触它也可以(每一列像素

15、的背电极都连在一起)，接着用右手拿刚才有感应电压那根电线，用裸露的线头分别接触各个段电极(即Y电极)，只要各个段电极所对应的像素点出现反应，那可断定该显示屏是好的。笔者通过这种方法检查后发现，当电线接触到各个段电极时，液晶显示屏都有反应。据此断定故障发生在导电橡胶上，可能是因为接触不良造成的。笔者用高纯度的无水酒精清洗导电橡胶后装回原处，接着将各部件还原，通电测试显示器可以正常显示，故障根除。维修小结为什么不用万用表的电阻挡来提供段电极的驱动电压呢？因为万用表电阻挡提供的是9V15V直流电压，表笔长时间接触段电极会损坏液晶面板，而上面所说的方法提供的是电流较弱的交流电，比较安全(这由液晶面板性

16、质决定，笔者不再详细解释)。但要注意的是用这个方法测试时，可能面板上电线探头没有接触的段电极对应的像素也有反应，这是悬空的电极上的感生电压造成的，属于正常情况。液晶显示器的部件是比较脆弱的，拆卸的时候必须小心，一定要注意防静电，同时要注意LCD显示器内同样有高压。另外拆卸LCD显示器也仅仅限于电路板的拆卸，如果你把液晶面板也拆了，显示器就报废了，这点一定要注意。例二：一台杂牌15英寸液晶显示器，屏幕画面紊乱且不稳定。故障分析参照上例中的方法处理后测试，发现故障依旧。但是当笔者无意中挪动电脑桌上的一只低音音箱时，却发现液晶屏上的显示画面也跟着有所变化，笔者立即切断了音箱的电源，并将音箱从电脑台上

17、搬走，此时该显示器突然恢复了正常的显示，故障竟然不治而愈了。维修小结一些用户错误地认为，液晶显示器不像CRT显示器那样，因有荫罩板和电磁偏转系统而害怕磁场干扰，其实液晶显示器经常在磁场中工作的话，同样会影响它的正常工作(拆开液晶显示器你就知道了，好的LCD的控制电路板外面都有一层金属的防磁罩)。SDFSFDSFDSFDTRTRTETRRETRET57868767567UIYHUG6675FUGFUSDFSFDSFDSFDTRTRTETRRETRET57868767567UIYHUG6675FUGFUSDFSFDSFDSFDTRTRTETRRETRET57868767567UIYHUG6675F
