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

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.
Repair Bible?
If you want a really, really thick bible-like guide on repairing SMPS, be sure to get one that has lots of easy to follow pictures and diagrams. If it offers personal email support from the author, that's even better!

How to Repair SMPS – 3 Effectively Proven Tips for Repairing Various SMPS
Want to learn how to repair SMPS as soon as possible?
Ah…I see you nodding your head…
That's good because I would like to share some SMPS repairing tips that will help you in a big way.
You know, some technicians opined that the process of troubleshooting and fixing SMPS units is a hard one, but for me…it is the opposite!
See, I've repaired dozens of switch mode power supplies - for computers, TVs, video game consoles and more. In most cases, they were easy to fix.
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.
