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!
