How to test defective Resistor

testing defective resistor

In this video training I’m going to demonstrate how to test a resistor and determine if it is in good or bad condition.

While waiting for customers, I decided to fix my Cellphone Repair Sign Board.

First I noticed that the power plug wires are stripped. I think it was because of the mice.

I opened the sign board and I visually inspect if there’s any sign of burn and it was my lucky day.

I quickly see the burn resistor. I desolder it from the PCB board, test and found out that it was open.
