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:

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!
