Power faults remains one of the most common faults when it comes to electronics.It may be due to power surge from ac supply ,high voltage or when a component fails at the power stage.What will be noticed is that the fuse will get blown and the mistake we normally make- especially beginners in the field of repairs- is to just change the fuse and power the set.This may result to greater damage of the power supply so it is better to check other components in the supply before deciding to replace the fuse only.Usually when there is a short circuit there is bound to be problem,you need to check for short circuit at rectifier diodes or power capacitor which are the major causes of blown fuse.In this series I will be examining different power supplies and how you can troubleshoot them.
