Brief description:
All the elements of the lcd maintenance field course are drawn from the experience of first-line maintenance staff and are suitable for study and use not only by a wide range of maintenance staff, but also as computer-based maintenance training materials. With the spread of the computer, the crt monitor has gradually been phased out and the lcd monitor has become a mandatory display device for modern computers (including computers in the context of household electricity activities). It is clear that the lcd display will be increasingly owned and that maintenance space and profits will increase。
From the point of view of maintenance practice, the lcd maintenance field course begins with a presentation of the treatment methods and techniques of common lcd malfunctions, focusing on the principles and maintenance replacements of over 10 large power sources and high pressure panels owned by society. At the same time, a number of operational lcd maintenance experiences were collected and described from lcd screens to lcd burners. In addition, approximately 40 power circuits and nearly 30 reverse circuits are attached for information。
