Features: Computers are not only widely used in various industries but are also increasingly prevalent in households. It can be anticipated that once computers reach a certain level of penetration in major cities, they will inevitably expand to larger numbers of medium-sized and small cities as well as rural areas. Like color TVs and other home appliances, computers may also require maintenance after prolonged use. The main component for repairing computer hardware is the display monitor. Since computer monitors share some functional similarities with color TVs, it is natural for computer users to seek the services of home appliance repair technicians who specialize in TV repairs when their monitors malfunction. To help home appliance repair technicians expand their repair services to include monitors and other computer equipment, we have compiled this book, New Computer Monitor Principles and Maintenance. Home appliance repair personnel with basic TV repair skills and general computer operation capabilities can gradually become proficient in repairing computer monitors through systematic study of this book.
This book is written for home appliance repair technicians, so it does not repeat the common circuit knowledge and basic troubleshooting techniques shared with color TVs and other home appliances. Instead, it focuses on the theoretical knowledge, circuit principles, and troubleshooting approaches specific to monitors. The book is divided into six chapters. Chapter 1 introduces the technical requirements and basic structure of computer monitors; Chapter 2 covers the video circuits of monitors; Chapter 3 provides a detailed explanation of the scanning circuits of monitors; Chapter 4 conducts a thorough analysis of the switching power supplies of monitors; Chapter 5 focuses on analyzing the circuit principles of four types of auto-scanning monitors; and Chapter 6 summarizes the key maintenance points of monitors.
The most engaging part of this book is Chapter 5, which not only provides a relatively complete analysis of the circuit principles of widely used auto-scanning monitors but also offers detailed information on the pin functions and actual measurement data of the integrated circuits used in these models. This is highly practical for technicians seeking reference material.
