Watt Zener Questions

Troubleshooting of SMPS – Learn Proven Tactics for Quick SMPS Troubleshooting

Troubleshooting of SMPS (switch mode power supply) is a lot more difficult than that of linear power supply…is this true?

Not really! With the right reparation reference guide and of course some practice, you’ll be able to troubleshoot and repair SMPS with very little trouble.

You know, I only learned how to fix SMPS not very long ago.  Although the first few repair cases were quite frustrating, I soon got the hang of it and began troubleshooting of SMPS and repairing them successfully…like a seasoned veteran!

So, I thought I’d share a couple of SMPS repair tips for the benefit of those who are still uncertain about how to conduct the proper troubleshooting process.

And speaking of, “reparation reference guide”…you will do well to get one that are in-depth, easy to understand and packed with step-by-step photos. I found one via this link :Info on SMPS Repair (Note: new window will open)

Now without further ado, here are a couple of proven tactics to assist you in troubleshooting of SMPS:

Help tip #1.

Examine the outputs located in the secondary area of your SMPS. Understand this: SMPS units are built with different number of outputs. Each one linked to a single circuit.

If an electric circuit occurs in one or more components/circuits, the power supply will shut down due to the increase of voltage supply. So, be sure to inspect the outputs in secondary area extensively.

Help tip #2.

If the fuse keeps blowing, then you should take a careful look at the diodes especially the zener ones (they are susceptible to burn out).

If problem persists after replacing the diodes, then you need to inspect the transformer or other components located downstream. They might be drawing excessive current.

To avoid changing fuse (in the event of power surge/ too much current pull), you should try linking a 100 watt bulb in series with the main fuse.

Fortunately, all the above and more repairing solutions can be obtained from an advice-jammed guide with full instructional photos.

You’ll pretty much learn everything from A to Z including troubleshooting of SMPS, understanding waveforms, voltages, schematic diagram, building your own diode and IC power tester and various repair instructions.

No need to wait for the 200 page photo-based repair manual to be shipped to your doorstep, just download, print and bind them for easy reference
