2. LV三色包

水晶甲是目前多种美甲工艺中最受欢迎的一种,其特点是能从视觉上改变手指形状,给人以修长感,从而弥补手形不美的遗憾。水晶指甲颜色晶莹剔透、粉白自然,可以和各种颜色的服装相匹配,衬托女性高雅气质。完美的指甲暗喻了充裕的时间、随意支配的收入及良好的自我控制,体现与众不同的个性,举手投足间尽显迷人风采。   水晶甲分为   <1>.自然型水晶甲:看上去和原来的指甲连成一体.   <2>.透明水晶甲:全透明的水晶甲.   <3>.法式水晶甲:像法式美甲一样尖端是白的延长甲.   <4>.有图案的水晶甲:在上面制作出图案的水晶甲.   法式水晶甲是水晶甲的一种 指甲前部有白色或者淡粉色延长部分   适合日常生活 在办公室里不是很打眼 显的也比较高贵 所以价钱贵一些 就像LV的包包一样 当然 也不乏假冒的   回、水晶粉和白色贝壳粉,如果只是涂在指甲上当然没有什么危害,去专卖店可以买当然会不舒服咯,手指觉得涨涨的,绞毛巾,穿衣服,打字都不方便,而且特伤指甲,做家务的话很容易掉的、对于伤害了的本甲,一般不要留长指甲,容易折断。也不要擦指甲油硬甲油之类的东西,对指甲很不好。让它自然生长少接触化学物品,像洗衣洗发戴上手套会好一些。指甲生长的快慢看个人体质,两三个月差不多。注意不要再进行抛光打磨。   水晶甲是怎么做的   常用甲型   生活中最常用的甲形有:方形、方圆形、椭园形,尖形四种,你可以根据自己的手形和喜好创造出完美的甲形。   A.方形甲 一般来说,方形指甲个性化及带领潮流,不易断裂,比较受职业女性和白领阶层的喜欢。   B.方圆形指甲 方圆形的指甲前端和侧面都是直的,棱角的地方成圆弧形轮廓,这种看上去很结实的形状会给人以柔和的感觉,对于骨节明显,手指瘦长的人,方圆形可以弥补不足之处。   C.椭圆形指甲 椭圆形的指甲,从游离缘开始,到指甲前端的轮廓呈椭圆形,属传统的东方甲形。   D.尖形指甲 尖形指甲由于接触面积小,易断裂,而亚洲人的甲形较薄,不适合修成尖形。   美甲制作   指甲分类不同,制作过程也不同。现就贴片指甲和贴片水晶指甲两种指甲的制作过程作一简单介绍。   第一种:贴片指甲制作过程 (贴片也称柔韧甲体,超薄弧型,用ABS系列新型材料制作而成)。   一、工具及必备品   1.消毒水 2.去甲水 3.软化剂 4.营养油 5.亮油 6.甲片胶   7.三色抛光条 8.水洗抛光条 9.100#磨锉 10. 桔木棒 11.指甲剪   12. 推皮砂棒 13. 指皮钳 14.

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。

你好,如果是专柜买的就不会假,红色那个是边油,就算真包背久了也是会掉的,LV的包带子背久了会变色就是真包,线头粗糙的大多是假包,还要看LV的拉链头一般比较有重量的就是真包,可以参考

6. lv三色包帆布包

YSL伊夫·圣·洛朗女士三色真皮高跟鞋,品牌:YvesSaintLaurent 伊夫·圣·罗兰,适合季节:秋冬,详细规格:别出心裁的帽型设计,时尚前卫,鞋跟高度11cm,制作材质:真皮,Slip-on风格,意大利制造。

.

这部分产品的面料辅料版型和专柜都是一样的,如果装上吊牌也是能进专柜的。所以这样的原单,可以说属于正品。但市场上还存在有尾单和跟单。如果是品牌代工厂出来的,在工艺图和。

2.

要说原单与正品的区别,一个有名分,一个没名分,但是属于亲兄弟的血缘关系。 原单值不值得? 原单衣服成本非常低,有时候为了清仓销售价格还低于成本,性价比很高,大家可以花不到一折。
