I have electronic equipment and after opening a fault I found a scorched track near an SMD component, which leads me to suspect it. However, he has no indication of what it is. I do not know if it's a diode, capacitor or resistor. Can you help?
In this case, we take a photo that we know to be a resistor, but SMD capacitors and diodes look the same. It is difficult to know what it is without knowing the diagram of the device. We can try to make a survey of the circuit, analyzing it logically. For example, if it goes to a nearby transistor we can try to find out if it is in the collector or emitter and thus imagine that it is a resistor, or if it goes from one transistor to another, suspect that it is a capacitor. Depending on the code used, we can use the internet to discover something.
