Features: To share the maintenance experience of high-tech color TVs with a wide range of home appliance repair personnel and electronics enthusiasts, we have compiled and written this book, "Essentials of LG Color TV Maintenance," based on our daily maintenance practices and experiences with LG color TVs. The book is divided into 10 chapters, with chapters 2 to 9 introducing the circuit working principles of the LGMC-51A, MC-51B, MC-71A, MC-8CB, MC-991A, MC-993A, MC007A, and MP-87A/B core units. Each chapter is further divided into two sections: the first section explains the working principles of each unit circuit, the origin and destination of various signals, the power supply processes of each integrated circuit, and the operation of protection circuits through actual maintenance measurements; the second section introduces the maintenance processes of common faults in the form of flowcharts. Chapter 10 provides examples of common faults to illustrate the fault analysis and maintenance process, with special notes on the replacement of specialized parts. Due to space limitations, the book only provides signal processing block diagrams or partial circuit diagrams for each core unit and cannot include complete circuit diagrams. Readers can refer to the circuit diagrams provided with the equipment when reading this book.
