Dear Electronic Repairer,

Like all my previous books, this home theater repair guide is written from the technician workbench point of view. No theories and long stories, therefore what is in this book is what you will expect first hand when a home theater is brought to your workshop for repair.

The author, Humphrey Kimathi has over 20 years experience in repair and service of home electrical appliances.

The book is divided into two parts:

Part one: is composed of 10 chapters on understanding major block in home theaters, common problems associated with those blocks and solutions.

Part Two: is composed of 6 chapters of pure real life repair histories of how I solved common home theater problems brought to my shop.

The book is illustrated with numerous color photos to make the reader learn faster and get the concept pretty fast.

Every Chapter is hyperlinked to the list of content for easy navigation within the book for those who decide to read the book directly from the computer screen.
