Microprocessor ICs are the most complicated part of TV equipment and present special problems to the engineer when fault finding. Each device is presented graphically with the relevant data information given against each pin which allows the engineer to quickly compare voltage measurements and signal in/out data on a faulty device, with those in the book. All the measurements and signal data in the book were taken under actual working conditions. The purpose of this book is to provide the workshop technician and the field engineer with a valuable and convenient method of fault finding without the need to consult workshop manuals which are often expensive or indeed out of stock. As such it will also be of interest to those on television training courses.
