The internal structure of the lcd television, its components, the parts of the circuits involved, the role played by each circuit, the links between the four main circuit boards of the lcd tv, the damage to one part, the resulting malfunctions, and how to analyse, judge and process them are explained in more detail。
The technical content of lcd television maintenance is clearly higher than the lcd monitor, which is easier from the point of view of maintenance than the maintenance of crt television, with fewer maintenance engineers, easier technology, higher fees, more efficient and faster. Free studies are now being offered for the lcd maintenance。
Full-day studies: 20 days
Amateur studies: 2 months
I. Basic
1) targeted description of the metaware and circuit base of the lcd television。
2) the types of television sets and their respective characteristics。
3) dismantling of high-level lcd televisions on site, explaining their internal structure, workflow (charting) and role。
Ii. Electronic circuits and electron sourcer courses break
The electromechanical device and circuit base are designed for students on a zero basis, with an understanding of the characteristics and characteristics of the electromechanical elements, such as electrical resistance, capacitors, electrons, transformers, crystallization, semiconductor diodes, transistor triode tubes, field effects triodes and integral chip symbols. The foundation is laid, the combination of these features will make it easier to understand the use of electromechanical devices in electronic circuits (width charts), to judge the good or bad of meta-systems by means of observation and universal gauges, and to replace them with different methods in practice. And in the course, together with practical little circuits, the interests and potentials of the participants are directed and developed to provide a solid foundation for better mastery of the monitors, the main panel, the hard drive, the lcd tv, the laptop, etc。
Iii. Working principles of lcd tv
1) detailed description and analysis of points and differences between intelligent and ordinary power sources. Smart power focuses on its working principles, fault analysis and handling techniques。
2) description of techniques for judging the electricity component。
3) the method of identification of the pressure plate and the points of care in its operation, treatment and substitution。
4) the method of identification of the driveboard and its working principles, treatment and points of care for replacement。
Iv. Functions reduction technology and elements
1) power supply, high pressure, drive, key, screen, remote control adaptation and handling of general television, high-resolution television, ultra-high-level television。
2) analysis of the failure points of lcd televisions and development of ideas for handling them。
3) handled by a variety of difficulties。
4) a failure can be resolved flexibly by a variety of means。
V. Characteristics of maintenance
1) conversion of lcd monitors into lcd televisions。
2) convert 5 key tv into 7 key tv, or 7 key tv。
3) talk about a variety of methods used by tv mmu
