平板电视维修技术的学习必须从理论开始

郝铭

上海市闵行区“莲花河畔景苑”在建的一幢13层住宅楼整体倒塌，什么原因：地基础没搞好，基础搞不好再美丽的建筑都是不能成功的。

电视维修技术的学习也必须把基础搞好，否则你永远也不会成功，只会停留在表面上，换换大板、换换功率管，没有钻研、没有追求；终将还是会被淘汰，一无所有。这种例子还少吗？。你只有掌握了基础知识、理论知识具有电路分析、故障分析的能力，才能把复杂故障的准确部位；迅速找到并把故障排除。在这个过程中，你会有大范围到小范围一步一步的准确寻找出故障的元件，故障的电视机对你具有巨大的引力，它一步一步的把你引向成功，故障排除的喜悦难以言表。没有基本功、没有电路的分析能力你能有这感觉吗？

现在的平板维修技术学习有相当一部分人，存在一个误区；认为学习维修技术不需要基础理论知识的学习，只要你在实践中教我什么故障这么修；教我怎么拆；教我怎么装的对号入座形式就行了，这样的学习你可能感觉很丰富，其实这是一种；空中阁楼的学习，学习后对于你具体学习的电视机的表面故障；你问题不大，但是对于深层次的故障（同步不好、图像抖动、无色等），或者其它类型的电视机你会感到力不从心。对于这些深层次的故障，往往故障现象一样；而故障的原因不一样、故障的部位不一样，你能寻找出来吗？

所以一个优秀的维修师傅，他必须具有根据故障现象；从电路的原理上分析故障、判断故障的能力，不管遇到什么样牌号的电视机、什么类型的电视机、甚至没有见过的电视机及没见过的疑难故障，都可以先通过对电视机原理图的熟悉、分析最终排除故障。这个师傅掌握了一定的电、电子、电视、电路基础理论知识，他一般不要参加任何培训班学习，只要新技术、新机型来了；自己利用自己的电路分析能力就把技术掌握了。

我们国家的著名的理工大学 清华大学 出来的学生是出类拔萃的，他们本科4年学习前三年也是在教室进行系统的理论学习，基础扎实了最后到实验室把学过的理论验证一下就可以了。所以我们的平板培训班应该是理论联系实际的学习，以理论学习为主，实践为辅的学习，理论实践的比例要合理，对于我们前期维修CRT的师傅们，要学习液晶、等离子电视的维修技术，一定要理解液晶屏、等离子屏的工作原理、工作条件、屏周边的相关电路，及新电路新技术（例如PFC技术等），新型元器件的应用（例如MOS管等），数字电路、数字信号的特点等。特别是单元电路的分析能力（振荡电路、放大电路等），加强这方面的积累、学习。这样你永远会跟上发展，甚至超前，一生都会很精彩，受人尊敬；还能赚到比较多的钱。

参加任何学习班，都要对课程的设置充分了解（教学大纲的系统性、实用性），是不是适合你，对于实习不要苛求，因为你们是搞维修的本身就有充分的实习机会，不要被各种广告、美丽的辞藻、诱人的照片所迷惑，这都是忽悠，捂紧口袋。

    Throughout the great design of things you’ll get an A just for effort and hard work. Exactly where you lost me was on all the specifics. As they say, the devil is in the details… And that could not be much more accurate here. Having said that, permit me say to you exactly what did deliver the results. Your writing is definitely quite powerful which is most likely the reason why I am taking the effort in order to opine. I do not make it a regular habit of doing that. Next, despite the fact that I can easily notice a jumps in reasoning you come up with, I am not necessarily confident of just how you seem to connect your ideas which inturn help to make your final result. For now I will subscribe to your position however trust in the foreseeable future you actually connect the dots much better.

    Jammer genoeg zijn er vele sites die valse beloftes maken en als je eenmaal op de website belandt doodgegooid wordt met advertenties, maar uiteindelijk
    geen gratis live streams van voetbal te zien krijgt.

    Jammergenoeg zijn er vele sites die valse beloftes maken en als je eenmaal op de website belandt doodgegooid wordt met advertenties,
    maar uiteindelijk geen gratis live streams van voetbal te zien krijgt.
    De voetbalwedstrijden in bovenstaand overzicht streamen de wedstrijden niet zelf, maar speuren het internet af naar aanbieders van de livestreams en geven deze in een overzichtelijke
    website weer. Realisatie website door Spruit Digital.

    De onderzoeksvraag was: Hoe hebben omgangsvormen, interetnische contacten en de participatie door middel van vrijwilligerswerk
    zich bij VV De Meern ontwikkeld in de afgelopen twee jaar?

    Mede op basis van de nulmeting zijn er sinds 2008 bij en door VV De Meern activiteiten ingezet
    zoals de Fair Play Cup en positief coachen, maatschappelijke stage en het Young Professional Project en een aantal andere projecten. Daarnaast is het commentaar bij de wedstrijden bijna altijd in een andere taal dan Nederlands.
