Foreword
The growing social ownership of computers has led to the spread of computer monitors. Considerable social demand has led to the production, sale and after-sale maintenance of computer monitors。
At present, the crt monitor still accounts for most of the market share, and after a period of “social grinding”, the crt monitor has begun to enter the cycle of refurbishment and maintenance。
As a computer monitor, its work is characterized by long working hours, in many cases the computer monitor is in the same permanent working environment as the computer host, and some monitors work in a mobile environment, so that the computer monitor has a high number of malfunctions and its parts and symptoms have varied. Although basic graphic principles are similar to television, as computer monitors are connected to computer hosts, software factors, digital factors and the addition of new devices and new circuits make the maintenance of monitors more difficult and, for these reasons, it is difficult for many people involved in traditional household electrical maintenance to adapt to and master the maintenance patterns of computer monitors。
In order to enable readers to learn quickly about the maintenance techniques of the crt monitors, we use the presentation of the actual prototypes “step-down”, “real reading” and “realization” and “realization” of the entire operation and overhaul process. Physical graphics are presented in the book, which attempts to simulate the perception of maintenance in the book, so that the reader can learn as if he were in the maintenance field and can follow it, try to fix it, image, live, visual, easy to learn, and really get in。
In order to make the contents of the books more practical, examples of maintenance of the books are derived from actual maintenance cases, and all test operations and detection data are derived from actual operations, thereby greatly increasing the practical value of the books。
The circuit maps collected in this book are those of the original plant, which involve, for example, meta-ware symbols that do not meet national standards, but are not regulated at the time of their editing, mainly for ease of reference。
The participants were mainly han guangxi, han snowtao, wu yong, zhang limei, mon shemei, guo haijie, zhang myung jie, liu sudong, hurlily, manan, lee shek, zhang zatan, wu zhong, han snow winter, etc。
As part of this teaching, the book is accompanied by a vcd presentation cd-rom, which consists mainly of video presentations on the maintenance of the crt monitor (extracted part)。
At the same time, in response to the needs of the maintenance staff, we have also produced a complete set of crt computer monitors for the maintenance of vcd teaching cds, which can be obtained by contacting us。
“crt display maintenance skills” also fall within the scope of professional qualification in the electronic information industry, and technical staff engaged in crt display maintenance should also take part in the vocational qualification examination and obtain a uniform national vocational qualification. The book can be used as a skills training tool。
Readers can contact us directly if they have problems with teaching or vocational qualification。
