If you want learn how to repair smps like the pros, let me offer some tips that can help you out immensely…
See, I've fixed a fair share of linear power supplies. They were pretty easy to fix but switch mode power supplies?
Well, to be honest…I had quite a hard time troubleshooting my first smps case. At the time, I had no prior experience fixing a smps and I found the circuit design to be rather complex.
Smps circuit design is so much different than the linear ones! Anyway, I managed to track down a downloadable manual on how to troubleshoot and repair smps so that made things a lot easier for me.
Now I can pretty much fix all types of switch mode power supply.
By the way, you can visit this site for more details on that repair manual(a new window will open).
Now, if you're ready to repair smps like the pros, then take note of these tips:
Tip 1: Learn how to read schematic diagram and understand the function of each component a.s.a.p! Knowing these will help you better isolate the possible causes of failure, therefore allowing you to complete the repairing process in an efficient manner.
Tip 2: Most smps problems are down to faulty filter capacitors, blown fuse etc. One of the things that you should check is decayed glue covering the fragile components.
This is a very common problem and can be solved by removing decayed glue from the components in a layer-by-layer fashion. Do it carefully to avoid damaging the components.
Tip 3: Should you encounter a problem that requires soldering, ensure you use a low watt soldering iron with very fine tip for small components.
For bigger components, use a higher watt soldering iron – maybe get a mini soldering gun to make things easier.
Listen, the best way to repair smps problems (if you have minimal experience) is to follow clearly explained instructions that helps you every step of the way.
