nedc 续航里程和实际大概差88折到9折之间。以下是关于续航的更多资料:1、分类:在一般的续航测试中会有三种续航标准, NED C 、 WLTP 、 EPA ,目前对于国内的新能源汽车来说,大多数会采用 NE DC 的标准,在国外大多数会采用的 WLTP 和 EPA 。

2、 NEDC : NED 的全称为:New-European-Drivi ng-Cycle ,中文意思为“新欧洲驾驶循环周期”。可以见得,我国现在使用的工信部续航里程标准就是欧洲标准。 NEDC 的续航里程测试主要模拟环境有市区和郊区,占比分别为4:1。因为实际路况环境影响因素较多, NEDC 的测试基本为台架试验。

3、 WLTP : WLTP 的全称为:World-LightVehicle-Test-P rocedure ,中文意思为“世界轻量型汽车测试程序”。其最大的特点就是很大程度上依赖于从真实世界的驱动周期上监测出数据,同时又更高程度的反馈于路面。

专科一般指大学专科教育,是高等教育的重要组成部分,是大学的学历层次之一。在中国,大学专科教育主要由高职和高专承担,部分本科高校亦开设有专科。

高升专方法

一种是参加普通高考,考取统招全日制大专、一般是在校学生考取。

如果是已成年,没有在读高中的话,可以参加成人继续教育,考取国家认可的大专文凭。成人可以通过自学考试、成人高考、网络教育、国家开放大学四种方式取得国家认可的文凭。

下面分别介绍下两种方法是如何升大专,首先我们先介绍下如何通过成人教育升大专。

成人教育

自考高升专

自学考试是开放式高等教育制度,它以国家考试为主导,以个人自主学习为基础。因此,通过自学考试拿到的毕业证含金量高。

报考条件

1、具有中国国籍,年满18周岁;

2、报考专科的,学历不限,不管小学是否毕业都可以;

3、报考本科的,办理本科毕业手续之前,必须拿到专科文凭;

4、能遵纪守法、积极学习的劳改、劳教人员,经有关部门批准后也可申请报考;

5、不受性别、年龄、民族、种族、学历、身体健康状况、居住地等限制,均可报考。

考试时间

自考大专一般每年有两次考试机会,分4月自考和10月自考,自考报名时间一般为考前1-2个月,各省各不相同。

报名方式

网上报考流程如下:

1、登陆各地自考网上报名网站。

2、到自考办网站规定的指定银行办理一张缴费用银行卡。

3、办理银行卡后的新生,和有银行卡的老考生按照报名网站规定的报名流程上传报考信息。

4、网上报名成功后的新生需要在考办规定时间到自考办进行摄像制作准考证。

5、如有任何疑问请和当地自考办联系。

现场确认环节如下:

1、新生携带身份证、(军人凭军人证或团以上单位证明)(未满18岁凭户口本)到所在地的市、县自学考试办公室(报名站)办理报名手续。

2、同时携带2B铅笔或蓝黑色钢笔签字笔(填涂机读报名卡用)、并交一寸同底免冠照片若干张(大约4-5张)。

3、按照工作人员的提示进行缴费,得到打印的考试通知单,通知单上有考试日期、考场和座位号。

4、在考办规定的时间领取新制作出的准考证。

方式二:找一个大点得知名机构,机构会安排好一切。

考试科目

自考大专考试科目分为公共课和专业课,一般考12-14门左右。公共课是指自学考试中任何专业或部分同类专业的应考者都必须学习的课程,有思想道德修养与法律基础、毛概等;专业课是根据考生的专业来定的,比如会计专业中的《高级财务会计》、《金融理论与实务》、《审计学》、《会计制度设计》等。

合格标准

自考公共课及格分数

自考理论课成绩的合格成绩是60分,自考考生需要考试计划中所有规定的考试科目都要达到60分及以上,其中也包括加考和选考的科目。

自考专业课及格分数

自考专业课和公共课的及格分数要求是一样的,所有的专业都是60分及格。自考实行的是60分及格制,每个自考考试科目达到60分或以上成绩就可以拿到单科的合格证书。

自考实践课及格分数

自考实践课程及格分数也是按照60分制来的,因此自考实践课也是60分及格,但是大家要注意,自考实践课的考核方式与理论课程成绩是不一样的,考核的成绩评定也不是简单的打分,而是先将成绩评定分解成若干的项目并按照百分制进行评分,再将评分换算为优秀、良好、中等、及格以及不及格几项,部分实践环节考核只采用及格和不及格两项,自考考生需要达到及格及以上才可以。

成绩查询

查询自考大专成绩的渠道有三种:

第一种就是携带好相关证件和资料,去当地自考大专中心直接进行查询;

第二种就是可以通过所在省的自考网上进行查询;

第三种就是需要能够通过书籍短信查看具体的发送代码进行查询。自考大专成绩一般在考后20至30天内出来。

备考方法

首先,自考是可以完全自学的,基础好,时间充足,想自学就自学,报班不是必选项。你如果时间少,基础相对较弱,想提高通过率,可以选择报机构助学,看你个人实际情况,不要人云亦云。

完全自学建议

教材购买:

第一步,在官网查到你所报考专业所需的科目,记录一下课程代码和课程名称,每个科目都有对应的使用教材。

以北京汉语言本科为例

输入课程代码+教材名称去淘宝网或者当当网或京东闲鱼搜索,在商品详情页里确认一下出版信息和官网教材一致就可以买了。

如何用教材学习?

第一步,看教材大纲,通读一下,知道这本书要学啥,哪些是重点。

一本教材很厚实的,但里面的知识点不是要全部学会。自考的目标是60分过考,你可以选择只学重点。

拿这个中国古代文学史二举例,大纲会标出重点,比如宋代“白体”“西昆体”“晚唐体”等等

第二步,了解考试题型

教材中会附在教材大纲后面,一般分选择题和主观题,有的专业如近代史和马原都是50分选择,50分主观题,可以在选择题多花些功夫。

第三步,看真题,看真题,非常重要

自考和我们国家其他考试一样,经常重复考一样的知识点。所以学习近几年的真题非常重要。真题可以去网上找资料,有很多免费或者付费的资源分享,有些淘宝店也会出售历年真题,价格不贵,从网上买也可以。

有人是反过来,从真题倒推去看教材,在教材划重点,再去学习,也是可以的。真题真的很重要。

第四步,就是学会合理地利用复习资料。

比较推荐像自考通和考纲解读这几种教材,这些都是按照自学考试专升本的教材章节来编排的,在章节里再对知识点进行比较详细的解读,比较适合基础较差的同学来复习。当然,基础好的同学只要直接粗略看-遍教材,就可以使用一-些全真模拟试卷来巩固,再结合历年的真题进行排查,梳理出自己漏掉的知识点,再对其进行归纳总结。

报班学习建议

如果选择机构辅助学习,那需要注意的是视频课+题库结合。真心建议在考前一个半月或者2个月开始学习!跟着老师直播上课的节奏走。

跟着老师学

一般老师会把一科分成12节精讲+3节串讲,简单的课程就是9节精讲课+3节串讲课,每节课都是2个小时左右。串讲课是考前老师用3节课,把整本书的重点串起来再复习一遍,一定要听。

如果这科目是12节精讲的,我建议你一定要听精讲,说明它知识点真的很多。

报班的大多数科目,都不用买教材,因为都有老师会提供官方笔记和密训资料,老师让你打印哪个资料,你就打印哪个资料。但老师让你买教材,你就最好买教材,这个要听你们任课老师的。

刷题

每次上完课有作业,老师也会组织刷题,当时一定跟着刷一刷,能记住不少。如果是考前抱佛脚的时候,那刷完题库之后,一定记得把近几年的真题做一遍,到考场绝对能看见几个熟悉的。

刷题之后,把你经常错的题记录下来,非常有用。

PS:不管是报班还是自学的,都建议大家准备一个错题本,只记录错题,超级好用。

统招高升专

统招高升专是在校生通过高考考入专科院校,或者是再高考前参加单招考试,提前被专科院校录取。

填报志愿

一般填报志愿每个省份得时间不一样,具体得大家可以参考各个省份教育考试院填报,专科在本科批次之后。

高考统招得流程如上,下面讲下单招得流程。

单招

考试基本信息

定义

单招,即为高职单独招生的简称。简单点来说就是高职高专层次学校的自主招生。它主要面向中职学生和普通高中生。

和高考区别

1、院校选择面不一样。单招考生只能选择本省的学校进行报考,不能报考外省的学校。就是说,如果你想读省外的学校,对不起,你是没有资格报考的。

2、招生对象不一样。单招可以面向普高生和中职生,考试分类也可能分成很多类,如河北就分为十大类。

3、考试难度不一样。单招是以文化素质+职业技能为主,考试难度相对来说比较低,考的知识点基本上也都是高中的基础知识。虽然考试科目都是语文、数学、英语,但是难度却是差得很远的。

4、基本上没有本科院校。单招大部分都是以专科为主,很少有本科参加。如果你想考个本科,建议还是走高考吧。

适合单招的学生

1、平时成绩不是很理想的学生,尤其是一些中职生、三校生,通过高职单招考一所专科学校是非常不是错的选择。

2、严重偏科的学生。如果平时偏科非常严重,建议走单招,虽然不能参加全国统考,但是考上后拿的毕业证和文凭和高考是一样的。

3、对自己没有信心的学生。如果在下半年,自己想放弃学习,不想呆在学校的话,不如提前走单招,3月份考完就可以离校了。

4、考本科没有希望的学生。假如觉得自己的成绩上不了本科线,还不如提前参加单招,考个好点的专科学校,选个就业好的专业,也是一种不错的选择。

考试时间

高职单招是全国各省市部分专科学校在每年的3-4月进行的一次单独考试招生,具体的时间可以查看每年各省各学校公布的招生时间。例如河北石油职业技术大学,可以进入官网,进入招生页面,查看时间。

考试科目

单招考试一般考核数学、语文、英语和综合素质四科。综合素质考核分为上机考试和面试两部分,上机考试就是在考生计算机上答题,面试则由专业面试官负责,主要考察学生的临场反应能力、语言表达能力、心理素质、知识储备量等。但这里要注意的是,不同省份、不同学校考试科目略有不同,具体请查看每年各省各学校公布的招生政策,具体查看方式类同考试时间查询方式。

特殊说明

大部分单招考试招生的学校都不能跨省招生,截至2022年全国只有三所学校能跨省,具体名单为:北京社会管理职业学院、长沙民政策职业技术学院、重庆城市管理职业学院。这三所学校在全国具体招生哪些专业,所以要具体以各校招生简章去看。

公布时间

学校单招考试成绩查询时间预计是4—5月就公布了。不过各地的单招查询时间可能会有差异。考生要是想要第一时间了解成绩查询时间的话,建议考生到所报的单招学校官网去看一下公告之类的消息,或者时刻关注官网上的动态,以便自己能够及时查到自己的成绩。

成绩查询

1、进入学校官网。首先在浏览器上输入所报院校名称并搜索,点击进入带有官网标识的网站。

2、找到成绩查询入口。一般情况下,在学校官网菜单栏会开设“招生就业”或“单独招生”栏目,点击进入即可找到成绩查询入口。跳转到招生网后即可进入成绩查询系统查询成绩。

3、成绩复核申请。如果对自己的成绩有疑问,可按院校规定申请成绩复核。如果各位同学认为自己的分数有问题就一定要申请成绩复核,不要怕麻烦。

合格标准

一般的单招最低通过分数标准在180分到200分之间,部分学校会有差异,热门院校的分数线会相对高一些。考生只要超过最低分数标准都是可以被单招院校录取的,不过根据目前大部分大专院校来看,其分数线一般在总分的60%左右。

备考方法

打好基础

从高一就打好基础,列出的所有需要考生掌握的基本概念、基本知识点都熟练掌握,遇到不理解的概念一定要向老师或同学请教。在此基础上做练习题,不求题海战术,只追求做题的质量。从最近几年的专升本数学试卷来看,大多是常规的题,偏题难题不多,考生备考时需注意打好基本功,不可为了少数难题做对而轻视常规题的练习

多做题

我们从考试试卷结构来看,英语试题主要分为词汇语法题、填空题、阅读理解题、短文写作题4个部分。这些知识要想掌握熟练,考生必须做足够的题。通过做题,尤其是做真题,才能知道考试到底考什么、以怎样的方式考、难易程度如何、命题人思路是什么等问题。在有错题的时候,考生一定要认真思考,但不是按照自己的思路,而是调整思路和标准答案保持一致。当然,做题的前提是词汇的积累,尤其是在这个暑假,积累大量的词汇。

刷题技巧

其实,我们的刷题过程就是为了以下五点内容:

培养计算能力

计算能力可以说是一切的基石,是每个理科生的必备能力,它代表了你的做题速度和准确度。

一道题不能只有思路,同时还要有极强的计算能力。单单就数学这门科目来说,很多人根本就无法答完一张卷子,做卷子时常常也是漏洞百出,丢了无数不该丢的分数。刷题的第一个意义就在于训练你的计算能力,让你的计算更为精准,让你的做题速度逐步提升。

学会新思路

刷题的第二个意义就在于让你学会新思路,让你见到更多的新题型。

很多题型你刚见到时不知道这是啥玩意,完全没有一丢丢思路,可是在考完试后经过老师的讲解,你明白了整个过程。当你下次再遇到时,解决起来也会是游刃有余。就像数列问题,我们所学到的最基础的两种题型就是错位相减和裂项相消,到后来遇到了更多的新题型,我们也就学到了许多新思路。

明确易错点

考试的题目中存在好多易错点,那些东西就是出题人所设置的陷阱,是他们早已安排的坑,等你这只猎物上钩。

就比如说这道题目中的锐角三角形就是限定条件,是为了后续解题埋伏笔。

这些类似的东西,最开始做题的时候你可以不注意,踩进了陷阱中,可是当你下一次遇到的时候,你必须要对这些关键词敏感起来。

这便是刷题的第三个意义——明确易错点。

明确公式使用

很多人把公式和知识点背的哇哇熟,然而等到考完试过后,他们的名次却远远落在后面。因为他们只会背不会用,根本无法把题目上的信息和所学过的知识给联系起来。所以我们必须通过做题来认识到信息和公式是怎么用的。

查漏补缺

因为所考的内容是固定的,出卷人再怎么出题也飞不出考纲上所划定的范围,很多时候你以为把知识牢牢掌握了,但是在做题时会让你发现还是有着许多的问题。当你做题时,你会发现自己哪块知识存在漏洞,你会发现自己哪个公式运用的并不熟练,而这些就是你存在的问题,就是你接下来努力的目标。

自从液晶电视上市以来,逐渐受到了人们的喜爱,很多人家里都安装了液晶电视。和普遍的电视机相比,液晶电视比较省电、较为环保。但是对于电器来说,使用久了,出现故障也在所难免,那么该如何维修呢?

基础知识

组成结构

液晶电视机的组成原理,大体有4个主要功能模块电源板,电视主板,逻辑板,背光模块,以及屏线,遥控器,按键输入和喇叭输出。

电源板

顾名思义,电源板负责整台电视的供电。功能好比人的心脏,给人全身输送能量。如果电源板坏了,就像人的心脏停止跳动,电视机自然就不能工作了。

很多黑屏,背光不亮,指示灯不亮,遥控按键不起作用等现象都是因为电源板故障引起。

电视主板

电视主板是整个电视机控制的核心,也可以说是电视的大脑。

如果电视主板出现问题,可能导致指示灯不亮、或者指示灯颜色异常、遥控按键无响应、黑屏、花屏等现象。

逻辑板

逻辑板也称TCON板,是信号中转站。负责将主板的LVDS信号转换成屏能处理的TCON信号。

如果TCON坏了,可能导致画面黑屏,花屏,条纹干扰,屏闪,屏保等异常现象。

背光模块

背光模块的功能是给电视机显示提供背光光源。

如果电视背光不亮,很有可能是背光模块出现了问题。

LVDS信号线

屏线,又称差分信号线。如果接口松动,接触不良,很容易导致黑屏,雪花点干扰,花屏等异常现象。

注意:4K电视,因为数据量大,LVDS信号线已无法满足传输要求,一般都采用V-BY-ONE的信号线传输。

遥控接收头

遥控接收头,也称IR,负责接收遥控器的红外控制信号。如果按遥控器没有反应,可能是遥控接收头出现问题。

按键板

如果遥控器可以正常操作,但按键板不起作用,估计是按键板或者相关电路坏了。

三合一板卡

将背光模块,电源板和电视主板集合到一块板卡上,俗称三合一板卡。将背光模块,电源板和电视主板集合到一块板卡上,俗称三合一板卡。

随着产品的标准和规范化,电视模块将越来越简化。目前市面上的电视,里面的模块基本都简化成两片电路了,一块三合一主板加一片逻辑板。

工作原理

如上图,红色的箭头是供电电路,蓝色的箭头是信号电路。

电源板负责将220V交流电压转换成各个模块工作所需的直流电压;

电视主板负责处理按键信号,响应遥控器信号;

控制电源板开关,直接或间接控制背光模块;

接收各类视频信号,图像转化成LVDS信号输送给逻辑板;

声音信号输出到喇叭;

逻辑板主要功能是将电视主板输出的LVDS信号转换成液晶屏能处理的TCON信号;

背光模块负责给背光灯条供电。

维修常用工具

螺丝刀

螺丝刀是工具,分手动或电动,用于旋拧(安装)和旋松(除去)螺钉。

镊子钳

夹持导线、元件及集成电路引脚等。

万用表

,万用表又称为复用表、多用表、三用表、繁用表等,是电力电子等部门不可缺少的测量仪表,一般以测量电压、电流和电阻为主要目的。

示波器

示波器是一种用途十分广泛的电子测量仪器。它能把肉眼看不见的电信号变换成看得见的图像,便于人们研究各种电现象的变化过程。

温度可调热风枪

热风枪主要是利用发热电阻丝的枪芯吹出的热风来对元件进行焊接与摘取元件的工具。

电烙铁

电烙铁是电子制作和电器维修的必备工具,主要用途是焊接元件及导线。

锡丝

锡丝的特质是具有一定的长度与直径的锡合金丝,在电子原器件的焊接中可与电烙铁或激光配合使用。

维修技巧

基本维修的方法

直观法

肉眼观察烧黑的地方,看有无连接线松动及元器件击穿的情况。

触摸法

用手触摸关键部件,观察供电部分发热情况(数字板),特别是对老化几小时后出现的软故障情况比较实用。

问题法

了解故障出现的具体状态(比如雷击、打火、冒烟、积水及以及人为操作等)。

测量法

使用万用表、示波器测量(有些情况可用指针式万用表交流来代替示波器测量一些普通的信号)。

代换法

有条件的情况下,可以代换电源板,数字板,高频板,背光板,屏,LVDS数据线,软件等,这种方法维修快。

排除法

缩小检修范围,准确判断故障位置(如信号源部分、信号通道部分)。

逻辑检修法

该方法要求对所修板件的信号流程、电源逻辑关系非常熟悉,可以确定维修的顺序:是先从后级向前级检修,还是单一通道向公共通道检修等等。

满足法

先大体确定故障部位后,再检修部分电路的工作条件是否满足(特殊情况下可人为制造工作条件)。

对比法

条件允许的情况下,可以对比好的板件进行检修,也可以对比同一板件上相同的电路(对称电路)来进行检修。

先软件后硬件

软件涉及的故障范围广,但是需要检修的范围小,对于一些软故障,建议先升级软件。

初步检修流程

维修口诀

液晶维修并不难,工作原理记心间;

电压来自电源板,亮度来自背光源;

信号处理机芯板,显示分配控制板;

5V供电最勤劳,一年四季歇不了;

12V供给机芯板,中放功放向它看;

24V送到背光板,无它屏幕缺光源;

机芯板子是领导,开关信号向它要;

电源模块背光板,电平高开(机)低关;

PWM脉冲很重要,少了亮度提不高;

LVDS线要求高,变质松动有干扰;

液晶电视不普通,程序经常闹罢工;

三天两天发神经,需要复位来摆平;

液晶屏幕很脆弱,要维修时细(心)操作

平板维修费用高,学好技术很辛劳;

赚钱固然很重要,安全二字记心牢。

常见故障分析

显示器整机无电

1、电源故障

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,易损的一般是一些小元件,象保险管、整流桥、300V滤波电容、电源开关管、电源管理IC、整流输出二极管、滤波电容等。这些常用的芯片在专业液晶配件店里都能买到。

2、驱动板故障

驱动板烧保险或者是稳压芯片出现故障,有部分机器是把开关电源内置,输出两组电源,其中一组是5V,供信号处理用,另外一组是12V提供高压板点背光用,如果开关电源部分电路出现了故障会有可能导致两组电源均没输出先查12V电压正常否,跟着查5V电压正常否,因为A/D驱动板的MCU芯片的工作电压是5V,所以查找开不了机的故障时,先用万用表测量5V电压,如果没有5V电压或者5V电压变得很低,那么一种可能是电源电路输入级出现了问题,也就是说12V转换到5V的电源部分出了问题,这种故障很常见检查5端稳压块(常见型号8050SD-LM2596-AIC15-01等)。

另一种可能就是5V的负载加重了,把5V电压拉得很低,换一种说法就是说,后级的信号处理电路出了问题,有部分电路损坏,引起负载加重,把5V电压拉得很低,逐一排查后级出现问题的元件,替换掉出现故障的元件后,5V能恢复正常,故障一般就此解决,也经常遇到5V电压恢复正常后还不能正常开机的,这种情况也有多种原因,一方面是MCU的程序被冲掉可能会导致不开机。还有就是MCU本身损坏,比如说MCU的I/O口损坏,使MCU扫描不了按键,遇到这种由MCU引起的故障,找硬件的问题是没有用的,就算你换了MCU也解决不了问题,因为MCU是需要编程和写码的,在没办法找到原厂的AD驱动板替换的情况下,我们只能用通用A/D驱动板代换如151D或161B等。

显示屏黑屏,无背光,电源灯绿灯常亮

斜视液晶屏有显示图像,是因为MCU问题造成没有输出开关控制电压,可以直接提取3端稳压块的。

(AIC1084)3.3V代替,修理高压板的思路(电源保险丝--开关控制管--电源管理IC--推挽发大管--电源开关管--DA转换电路(储能电感整流管)--LC升压电路(升压变压器、升压电容)--耦合电容--灯管。

屏幕亮线,亮带或者是暗线

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或者某行和列的驱动IC损坏

暗线一般是屏的本体有漏电,或者TAB柔性板连线开路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。(广州有专门更换码片的,收费极高,返修率也高)。

花屏或者是白屏

这种问题一般是屏的驱动电压出了问题,先换驱动板和驱屏线试验,若不行检查屏背板供电电路。

维修思路:驱动板5V转3.3V的稳压块(AIC1084)是否有供电输出--屏体驱动板保险丝(F)-3.3V--DC转换电路--负压形成IC(-7V)--行列驱动IC。

AAT1101AM150XN05屏电源管理芯片,损坏后表现为白屏开机图像暗淡等。

AAT1164M170EG01新款屏通病,主要用在明基FP71G+液晶显示器上面。用一段时间会白屏、关机在开用一段时间又出现白屏。本芯片为液晶屏高压产生及管理芯片、明基液晶显示器常坏、故障为:白屏。

偏色故障

一般可以进入工厂调整模式进行调整。

维修思路:更换屏线和转接板--重写驱动程序--驱动板坏(不常见)--屏背板的控制IC坏(不常见)--拔掉屏线观察背光颜色(背光偏色为灯管老化)--换灯管。

字符虚或拖尾

维修思路:检查VGA信号线,重点看RGB三色线的地线是否连接正常--更换屏线或转接板--重写驱动程序--换驱动板--LCD屏背板信号接口 IC坏--LCD屏背板对比度电位器调整--LCD屏导光板错位--偏光片错位。

LCD屏幕内部有污点

维修思路:擦拭或更换换保护膜--拆开屏体清洗外层偏光片和有机玻璃(用棉球纯净水处理)--风筒吹干。

LCD屏漏光或光线不均

维修思路:重新安装灯管--调整导光板。

LCD屏亮点

一个或二个大的亮点,可以尝试轻轻用指尖压亮点,可消失,说明多为此像素的开关管和电极虚连小的黑点和灰点有可能是内部导光板或偏光片有灰尘造成可清洗处理。

LCD屏亮度低

检查高压板ADJ亮度调节电路--换灯管--换高压板---调整或更换导光板。

错误提示超出频率范围

检查信号线--重写MCU驱动程序--更换EPROM--重写EPROM程序--换驱动板。

通电后不按开关按键即白屏,出现背光按键后图像可正常显示

高压板接口的开关信号和ADJ信号反接造成部分属于驱动板MCU的开关信号输出不正常,可以重写MCU程序修复--换MCU。

补充一点,对于灯管老化的屏更换时要搞清灯管的尺寸,因为尽管屏幕尺寸一样,但是灯管长度与粗细略有差异,在找不到相同尺寸灯管的时候,如果能用短灯则好,如果不能使用,稍长的的灯管用手术刀小心切除屏框,并用热缩管做好绝缘。

注意事项

电视机是有电高压的一种电器,维修时有关的安全问题一定要注意。

1、打开机壳:要注意不能用蛮力打开机壳,如果太紧打不开,一定是还有螺钉或卡扣没有松开,要再仔细找找;拉开机壳时有的电视机电路板与机壳之间会有电线相连,要注意不要拉坏,比较好先折下机壳上固定的电路板;拉开机壳时要拿稳机壳,不要脱手掉下,否则容易砸到显像管管径,一旦砸断可就麻烦了。

2、要注意电视机的“热地”:有的电视机的电路板的地是“热地”,就是与市电没有隔离,如果恰巧电视机的电源插头又将未隔离的电视机的“地”端插到市电的“火”线上,那么维修时如果你不小心碰到电视机的某个接“地”的部分,就有触电的危险。一方面触电本身很危险,另一方面人在触电时身体会发生不由自主的痉挛,一旦把电视机拉到地上,就又出大麻烦了。解决这个问题比较好是用隔离变压器,如果没有,比较好在电视机通电时能调整好插头方向,使电视机的“地”接到市电的“零”线上,这样可以使电视机比较容易碰到的地方不“电”人,但是电视机里还是有与“火”线相连的强电的,仍然要小心。

3、要注意电视机内的高压:在更换行输出变压器的时候,一定要用万用表笔或其它导线将显像管高压帽下的高压泄放干净,否则在摘下高压连线时会受到高压电击,同样比较危险。

如何保养

1、保持干燥

放置的中央,环境要保持干燥并远离化学药品。假如放置环境湿度很大,电器内部就会结露,容易形成漏电、短路等。平常使用的发胶、灭蚊剂等都是高挥发性化学品,也会对液晶显现屏形成损伤。

2、亮度调低

日常使用,尽量防止长时间显现同一张画面。长时间工作容易惹起内部老化或烧坏,特别糟糕的是长时间内显现同一画面,可能会招致某些像素过热,形成内部产生坏点。而这种损坏不能修复。因而不用时应该关闭显现屏或选择屏幕保护程序,或者把显现屏亮度调低点。

3、不能频繁清洗

液晶显现屏不能频繁清洗。正确的清洁办法是拿一块沾有少许玻璃清洁剂的屏幕擦布,轻力把污迹擦去。注意不要让清洁剂流到屏幕、屏框接口中,以免出现短路。也不要用硬质毛巾擦洗,以免刮花屏幕。还要定时定量擦洗。

4、制止坏习气

杜绝使用坏习气。不要用手对屏幕指指点点。此外变压器电压很高,不要在带电的状况下翻开屏的后盖。
