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.
