For those who are training to become an electronics repairer, here is another good material from Jestine Yong of the LCD Monitor Repair and Electronics Troubleshooting e-books that he created to teach those interested in learning how to repair electronics even with no formal education.
The said material is another e-book containing information on the secret to finding the resistor value of a burnt resistor.
A resistor is an electronic circuit component that is meant to resist the flow of electric current. It has two terminals that electric current needs to pass through. As it moves from one terminal to another, its voltage is reduced. Resistors are designed to do so to maintain a known current within a component of the circuit.
However, sometimes resistors overheat and burn when they fail to dissipate the high temperature caused by the electric current. When this happens, the color code on the resistor is destroyed and hence you are left unable to figure out how to get the resistor value which is important information if you intend to replace it to fix the device it is in.
The resistor value indicates the resistor’s resistance in ohms and is an important value to know. A working resistor’s value can be measured using an ohmmeter which may be function that modern digital multimeters are equipped with. However, if the resistor fails and is burned, you may not be able to obtain its value without the appropriate schematic diagrams. Now, since schematic diagrams do not fall freely from the sky and are usually quite expensive to get, you may find yourself stuck with the particular job you are working on.
Jestine Yong’s How to Find a Burnt Resistor Value will teach you a secret method to find out the value of a damaged and unrecognizable resistor so you will never have to turn down a repair request just because you cannot figure out a single number that will let you know which replacement to get.
Jestine Yong promises that the method he teaches will work on any electronic equipment. This should come in handy for those plasma and LCD TV repair jobs. He also swears that what he teaches will be easy to understand such that you do not even need to get the schematic diagram. It will be a step-by-step detailed instruction complemented by pictures and diagrams. You will not need no complicated equipment like oscilloscopes and other expensive testing equipment.
