Okay, let's boogie…
True or false? In order to fix various types of SMPS, you just need to know about the 6 circuit functions in SMPS.
FALSE! You must know a total of 11 circuit functions in SMPS. If you fully understand the mechanics of each circuit function, you should be able to handle just about any SMPS repair issues.
True or false? There are 6 COMMON issues found in SMPS units.
TRUE! The 6 common problems are complete power shutdown, high output voltage, low output voltage, intermittent power failure, power blinking/cycling and lastly, no power at all.
True or false? To successfully troubleshoot switch mode power supplies, you only need to use one testing tool - an analog multimeter.
FALSE! You need to amass a variety of tools and test equipment for troubleshooting various SMPS repair problems.
Apart from analog multimeter, you should also get a blue ring tester, blue ESR meter, AC ammeter, isolation transformer, zener diode tester etc.
True or false? There are 5 essential techniques for troubleshooting and restoring faulty SMPS.
TRUE! Here are the 5 essential techniques that you must learn: the isolation technique, the flickering technique, the secondary diode removal technique, the resistance technique and finally the blue ring tester technique.
True or false? One of the best ways to learn SMPS repair is via detailed, text-oriented service guide.
FALSE! One of the best ways is to refer detailed service guide that ALSO includes step-by-step photo directions along with one-to-one email support from an expert. You absolutely can't go wrong with this type of service guide.
True or False? Step-by-step, photo instructional SMPS repair service guide that provides email support doesn't exist.
FALSE! You can find a downloadable version by going to this link now.

Switch Mode Power Supply Repair – 3 Vital Tips for Repairing SMPS
I started doing switch mode power supply repair a couple months ago, and I can't believe how easy it is! Okay, okay the truth is….
I had to download a 200+ page SMPS repair bible to help me get started on the right path!
You know, I have pretty extensive experience repairing power supplies – specifically linear power supplies. However, fixing the switch mode type is a whole different ball game.
Anyway, thanks to that repair bible, I've now completed about 2 dozen switch mode power supply repair work. Cool huh?
Alright look, since I've gained some experience fixing SMPS, I'll share with you a few vital tips so you can get up and running as soon as possible.
And maybe if you feel like checking out the aforementioned SMPS "repair bible", just click on this link which I think will open a new window for you to have a look.
Okay, here are some useful tips for troubleshooting and fixing any type of SMPS…
Vital Tip (1)
In order to pinpoint the problems as quickly as possible, you must first learn as much as possible about voltages and waveforms in multiple sections of an SMPS unit.
Once you've fully comprehend these critical points, you'll be able to solve all sorts of switch mode power supply repair problems.
Vital Tip (2)
As a precautionary measure, you should conduct multiple tests without plugging in the equipment. An ohm meter can be used to determine whether the power supply failure is caused by short circuits.
Electrical devices like LCD TVs contain power supply with semiconductors that can be measured with an ohm meter unit.
Vital Tip (3)
If you can't find the voltage of a zener diode (lack of marking), then use a zener diode tester to help you out. This tester is primarily used for determining the exact cause of a zener diode however…
You can use it on other components as well! That's right my friend. You can actually use tester on your SMPS voltage regulator, schottky diodes and more!
Oh by the way, that repair bible also teaches you how to build your own zener diode. It's easy to do (just follow the instructions) and the cost is pretty low!
Go ahead and check out this link to learn switch mode power supply repair using step-by-step photos and precise diagrams.

Computer SMPS Repair – Top 5 Tips for Repairing a Computer's SMPS
Most Computer SMPS repair issues can be fixed in a relatively easy manner. Of course, you need to have some electrical repair experience; otherwise you're going to have a difficult time solving even the simplest of switch mode power supply problems.
What if you have v-e-e-e-r-y little electrical repair experience?
Look anything is possible, but if you lack experience, then I suggest you get a good, straightforward style technical guide on how to conduct computer smps repair (with lots of instructional photos for easy reference).
I discovered a really good one at this website.
It is a download only guide so it should quickly get you up to speed because you don't have to wait for the material to arrive on your door step.
On the other hand, if you have some experience then here's what you can do to fix your computer's switch mode power supply.
1) Determine the exact cause of failure. Is it a blown fuse? Defective capacitors? Damaged Schottky diodes?
2) Also be sure to understand the usage of each component. If you do not know the basic function of a resistor, a filter capacitor, primary and secondary diodes etc, then simply put…you won't be able to complete your computer smps repair process on your own.
3) Examine the circuit design properly. The more you know about the circuit design, the easier it will be for you to fix it. Understanding the whole design will make it easier for you determine possible causes of failure and the steps needed to rectify them.
4) Examine electrolytic capacitors on the main side. If you find that capacity is lowered, then it's likely that the transistor of the switch mode has been compromised.
5) Replace faulty electrolytic capacitors as soon as possible. Why delay? They are easy to replace and they don't cost a lot of money either.
Look, you can perform your computer smps repair without much problem. Lack of technical expertise is not an issue, especially if you refer detailed instructions that are downloadable and comes complete with color photos.
