I started learning how to repair switch mode supplies (commonly abbreviated as SMPS) about a year ago. Thing were pretty rough initially. I couldn't fix a single SMPS problem at first!
However, I managed to buck up and improve my repairing skills after I chanced upon a highly detailed SMPS troubleshooting and service manual (you may click here for more info).
Since then, I've reconditioned numerous faulty SMPS! I dealt with a variety of SMPS problems and some of the EXTREMELY common ones are as follows:
Problem 1: Acidic Beverages
Now, you may be thinking, "say what? Acidic beverages can cause problems to SMPS? Are you high or something?"
Look, it's true! I've discovered many faulty SMPS units that were stained with coffee, cola, even fruit juice residue!
Acidic beverages – even in small amounts – can cause severe damage to an SMPS circuit board.
Problem 2: Combusted Coil
This problem can easily be detected if the burn marks are located on the outer/external section of the winding coil. However, if the internal loop is combusted then there are only two ways to detect this particular SMPS problem:
(a) Use your nose to smell the coil!
(b) Take out the blue ring tester and use it to confirm internal loop damage.
Problem 3: Decayed Glue
I find this problem most annoying. It's such a drag to scrape off decayed glue that has covered multiple SMPS components! The hardest part is that you have to do it in a very measured fashion or risk damaging the components' delicate outer layers.
Problem 4: Micro Crack
On large-sized components, micro cracks are quite noticeable. But they are not quite visible on smaller-sized components so you're going to need a magnifying glass to catch them!
Problem 5: Lack of User-Friendly Guide
This was a major problem for me. I wanted to learn SMPS repair but a complete, user-friendly guide on this subject was very hard to find!
Most SMPS repairing sites are laden with text. They are so boring and very hard to follow along…
See the real secret to learning how to troubleshoot and repair SMPS is by using a reference guide that is straightforward, full of step-by-step photos, illustrations, diagrams PLUS email support from an accomplished electronics technician/engineer.
That's how I got so good at fixing faulty SMPS! Through practice and by referring detailed guide that also comes with support via email.
And you too can fix all sorts of SMPS problems by using a detailed, step-by-step guide with email help which is presented at Manual for Solving Numerous SMPS Problems

How to Troubleshoot SMPS – 3 Systematic Tips for Troubleshooting Any SMPS
If you can't seem to figure out how to troubleshoot an SMPS, then you might want to take a breather, kick back for a moment and read this article.
See, I understand that troubleshooting and repairing switch mode power supplies is no walk in the park. Many fledgling technicians are overwhelmed by the complexity of SMPS circuit patterns.
But that's not going to happen to you!
I'm going to give some very helpful tips including tools selection, where to obtain the best and most complete guide on repairing SMPS, and a few common issues that you need to look out for when dealing with a faulty SMPS unit.
Alright, let's get down to business shall we?
1. Technician tools on how to troubleshoot SMPS…
Set up the necessary tools from the get-go. Of course the Ohmmeter is a must have a tool, but other devices have their place as well.
I recommend you get these tools: magnifying glass, isolation and variable transformer, oscilloscope, AC ammeter, capacitance meter and also a blue ring tester.
Extra tip: The blue ring tester is handy for discovering burnt coil that occurred within the internal winding section.
2. How to get the best manual for repairing SMPS?
I recommend getting a manual that's not overwhelmingly text-based. Photo-oriented instructions are the most ideal and if it comes with personal email help from an expert technician – that's even better!
By the way, you can actually download a deluxe photo instructional guide on how to troubleshoot SMPS including support via email. Simply Click Here to check it out.
3. Common issues that you might overlook…
(a) Hairline crack – Very easy to overlook this one especially if it occurs in small components such as power ICs or diodes. Use your X10 magnifying glass to locate those tiny cracks.
(b) Bulged Electrolytic Capacitors (EC) – Newbie technicians tend to overlook this problem. Actually, bulged ECs are very easy to discover and should be replaced even if your test meter indicates that they can still be used.
(c) Dry joints in the connector section – Always check for loose connection. You see, the multiple connector points are quite prone to dry joints.
Dry joints occurring in the connecter section will lead to loosening of wires and cables!
Anyway, if you still need a downloadable guide on how to troubleshoot SMPS in a step by detailed step fashion complete with full photos and illustrations, just follow this link: Learn How to Troubleshoot SMPS Step-By-Step Manual

Troubleshooting SMPS – 3 Winning Ways to Troubleshoot Faulty SMPS
My "SMPS repair mentor" said this to me: "restoring linear power supplies is easy, but troubleshooting SMPS is much, much more fun!"
I can't agree more with him. Indeed, troubleshooting and repairing switch mode power supplies is more fun, but I have to warn you though…
If you don't know what you're doing, then things will get very, very frustrating because the circuit designs in SMPS are quite complicated.
But don't you worry now…
I'm going to give you some essential tips for troubleshooting SMPS. These tips I learned from my repair mentor. You know, he actually created a step by detailed step manual on fixing SMPS.
The downloadable manual contains lots of easy to follow photo intensive instructions so if you're interested in it, just follow this link (new window).
Okay, no more rambling. Here are some essential tips to help you troubleshoot an SMPS unit successfully.
Note: I assume you already know how to read schematic diagrams of SMPS, and you know full well about each and every component in different types of SMPS. If you don't know all these, then I recommend you check out the link above.
First Tip
So you have a faulty SMPS on your repair table… First thing you should do is study that particular SMPS unit. Specifically, study its circuit design. Doing so enables you to approach the problem from various angles.
Second Tip
Get all the necessary tools ready. Most novice technicians would have a volt-ohm meter for testing purposes, but that's not sufficient!
I recommend other repairing and testing tools e.g. isolation and variable transformer, AC ammeter, blue ring and blue ESR meter and also oscilloscope.
Third Tip
Once you've removed the casing, I want you to monitor the components carefully. See, when troubleshooting SMPS, two of the most common problems I encountered were decayed glue and high voltage transformer that had too many dry joints.
Also if you're dealing with a faulty SMPS that uses controller IC, use your oscilloscope. It's ideal for high output voltage, power shutdown or power pulsating/blinking problems.
Trust me, troubleshooting SMPS is FUN but you definitely need a handy reference guide if you lack experience. Here's a 271 pages SMPS repairing guide which is full of easy to follow photographic instructions.

SMPS Problems – List of Small Problems and The Biggest Problem for Novice Technicians
I've fixed all kinds of SMPS problems – both minor and major ones. And in all cases, I would isolate the problem as soon as possible. I suggest you do the same.
You must be able to identify exactly which section of the SMPS is causing the issue. You'll save a LOT of time this way!
Now, if you have an SMPS that isn't working, I think the source of problem can be attributed to the following:
Damaged SMPS components…
Inspect every section carefully to see if there's any broken/loose/totally detached component. Look at the primary section. Is the power IC working correctly?
Take out your UC3842 IC Tester unit to measure the power IC. Damaged capacitors is also one the most common SMPS problems so check those as well.
Main circuit board problems…
Noticed the power supply LED blinking/dim/ shutdown? If yes, then you should measure each component in the main area of SMPS. Aside from the main section; do check the secondary area as well.
Fan problem…
Trying to repair an ATX switch mode power supply? Inspect the fan! The fan is vital for sucking heat from the components. If the fan doesn't work properly, then excessive heat will occur, resulting in complete shutdown of your ATX SMPS.
Soldering problem…
Well, this is definitely not one of the most common SMPS problems around…. However, fairly big sized components can be found in most switch mode power supplies and soldering them can be rather difficult.
So, just check the solder connections too if you find nothing wrong with the components…
If you need to make adjustments to the connections and you're not too confident of doing so, then I suggest you test your soldering skill on a dummy circuit board first.
The Biggest problem for Novice technicians
The circuit design of switch mode power supplies is more complex than their linear counterparts. And to worsen matters, there is a serious lack of ‘take-you-by-the-hand' guides on how to troubleshoot and repair SMPS in the proper manner.
This I believe is the biggest problem for novice technicians. I know, because I went through the same experience.
Now, you can avoid this problem by visiting a website called SMPS repair information. I think the exact link is right here.
That's where I discovered a thick downloadable manual with step-by-step photos on solving various SMPS problems. Go ahead and follow the above link if you're interested in downloading it.

Repairing SMPS – What You MUST Know About Repairing SMPS
Repairing SMPS while wearing a blindfold…is that possible?
Of course not! Do not try to fix an SMPS unit while putting on a blindfold!
Sorry for bringing up that question. See, several nights ago my buddies got crazy drunk (I was slightly drunk too) and he asked me that question…I thought it was a really stupid but funny question :)
I can't imagine anyone repairing SMPS on a blindfold. Only a dumb maniac would attempt such a thing…
Anyway, sorry for getting off topic, just thought I'd share the fun. Now, if you need some SMPS repair tips, then let me share a few pointers with you.
Heck, I'll even tell you what SMPS repair manual I personally use to jack up my fixing and troubleshooting skills. By the way, you can look it up via the link below:
Photo-based SMPS instructional repair guide
Now, take a look at the following tips for solving your switch mode power supply repair issues…You ought to know them!
Basic yet often overlooked problem…
Check for faulty or incorrectly positioned voltage selector switch. I've seen this happen many times. The equipment is moved around resulting in the aforementioned problem. Accidents happen…
Look sharp!
Upon removing the casing – look sharp! Look for what? Well, look at each component…Perhaps the electrolytic capacitors are broken or slightly loose? Decayed glue impeding components? Too much dust?
Repairing SMPS can be hard if there are layers upon layers of dust covering the components. So, get a mini vacuum.
Promptly change the damaged capacitors. As for decayed glue, just remove by scraping carefully as to avoid damaging the affected parts.
Solder of fortune…
Yes, you read that right - solder of fortune. You see, it may cause you a small fortune should you mess up the soldering process!
SMPS failure may also be caused by shoddy solder connection job by the manufacturers.
Use the right soldering items e.g. a fine tip one for small sized components, while a soldering gun is ideal for bigger sized parts.

Of course, I had a highly organized manual on how to repair SMPS which I refer from time to time, and that made it easy for me…Should you need one, then I suggest you take a look at this website.
Listen, as I said…Repairing an SMPS is not hard. Kindly take note of the tips below to set yourself on the right path…
1. Diagram Education!
It's critical that you learn how to read the schematic diagram of SMPS. Understanding the diagram is fairly easy and once you know how to do so, you will quickly be able to conduct the proper problem isolation process.
This in turn, will help you pinpoint the true causes of failure!
2. Avoid wasting money!
Do you think it's the power IC that led to the failure of your SMPS unit? Think again! I know some folks would simply replace it without conducting the proper inspection.
I made this mistake when I handled my first few faulty SMPS cases :P Wasted some cash because of this…
Listen, I suggest that you use a UC3842 IC Tester to accurately check the condition of your SMPS power IC before actually replacing it. This will save you money.
3. When in doubt, get email help from an expert!
When I first tried to learn how to repair SMPS over a year ago, I found the experience frustrating. I tried searching for step-by-step info on the internet, but the ones I discovered were too convoluted…
Finally, I found one that contains specific repair instructions with photos. But it gets even better…It also includes email help from a highly accomplished electronic engineer!
So yes, when in doubt be sure to email an expert to get the help that you need.
If you want to know how to repair SMPS in a step-by-step fashion with handy email support just in case, then follow this link for an easy to follow downloadable guide (if it's still available…).

Repair SMPS – Learn How to Repair Switch Mode Power Supplies Like the Pros!
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.
