You use many electronic and electrical devices in your home on a daily basis. What will you do if these devices break down? You might want to resort to troubleshooting your electronic equipment. In this course, you will learn about troubleshooting, which is a form of problem-solving. As you endeavour to repair failed products or processes on a machine or a system, you are troubleshooting. This course will teach you how to complete a logical and systematic search for the source of a problem to solve it, making the electronic and electrical devices operational again. Starting with the information you need to become a good troubleshooter, you will also learn basic electrical and electronic components and circuit analysis. The course will address repair and maintenance procedures in the context of troubleshooting. You will also be introduced to the basic things you will need to become a troubleshooter. These mainly include multimeters, screwdrivers and wiring tools. Other tools are referred to as miscellaneous or “do-it-yourself” tools.    

As you work through the course, you will learn that troubleshooting is one of the features on which depend the effective and efficient working conditions of devices. Other features include maintenance, servicing and repairing. Maintenance is the process that includes hardware and software. Associated with the hardware part of the equipment, servicing consists of four main steps that will be fully disclosed. How to uninstall all the physical components, starting from the power connection and clean dust from all the components; you will understand how to perform a visual or electronic check as required. The last step is about reinstalling all components carefully and adequately. Following on the servicing is the troubleshooting, which consists of detecting and rectifying faults in the equipment. After being able to correct the problem in the hardware or software, the course will give more of an explanation of the troubleshooting-related features.   

Finally, you will learn about the current flow of electrons, voltage and resistance, and measurement. You will be introduced to resistors and their parameters. Following the resistors, the behaviour and testing of capacitors will be highlighted. Having been acquainted with inductors, you will be taught how to test and measure coils along with the various diodes. This course will also cover transistors with some emphasis on switches and amplifiers. Practical testing of transistors will be addressed, allowing you to have a good knowledge of troubleshooting. This comprehensive course about troubleshooting will equip you with valuable knowledge, enabling you to repair your electronic and electrical devices. Troubleshooting professionals will find this course very useful to improve their knowledge and help them to be far more efficient.
