  • Fixing a 24V 10A 240W switching power supply module donated by a viewer. He tried to fix it, but couldn't find the fault. Everyone keeps learning during their whole life. No-one knows everything. Showing how to diagnose this 2-switch forward SMPS, so he (and other beginners) will be wiser next time. Testing transistors can be tricky. Neither I am perfect, I took the longer path this time :). The tricky situation when something with seemingly no bad components isn't working!

It was part of the SATA circuit and was a manufacturing defect (it was soldered improperly and when checking it it fell off the board entierly). I also used a soldering gun, in fact almost the same as he uses (a newer model with LED light instead of a bulb).

    Looking at the temperatures it looks like the specs are somewhat dodgy . 200W is only about 81% full load and this thing is already cooking. Its one thing for the Power semiconductors to get hot , but the magnetics , smd etc will end up drying out the filter capacitors and make it fail again. Great detective work on identifying the bad transistor !!

    Whenever I have one of these kinds of cheap power supplies that's died, I usually open it up thinking I can repair it, then decide it's not worth it after seeing the quality of the design and components. Even if I were to repair it, there's no way of knowing if some other cheap component is going to die after another few months, and I'll just have to spend more time and effort fixing it. A good brand replacement might cost more and take longer to arrive, but you'll save a lot more time and hassle in the future if you can afford it.

    Awesome repair. I've got a meanwell 24V supply in my bucket of junk that doesn't work, might be time to look into that one.
    Love these repairs!

    I keep an old analogue meter on the bench JUST for testing transistors in this way... in-circuit shorts are much more evident when you are testing with an appreciable current through the device.

    2:31 you can see the 2 diodes next to the 2 Transistors which can mean its a 2-switch forward or some other type of forward

    Why is it necessary a wide board space between primary and secondary? Is it displacement current?

    You can only repair such a power pack if you can get proper replacement parts which isn't always possible. And in my experience of electronic repairs power packs like this one and especially those used in PC's often use really obscure parts which can be well nigh impossible to even find information on them, never mind replacements, and such components often give really obscure readings on a meter too instead of straightforward faulty or ok. And of course sometimes the switch mode transformer fails with shorted turns and rewinding it is definitely not for the faint-hearted, it takes tons of confidence, patience, and of course the right skills and equipment.

    I have seen _one_ common mode choke like that before. It's on the cracked laptop PSU I happen to have on my desk right now.

    A most excellent repair. 🥳 That power supply was lucky to work at all with the poor soldering job. Thank you for the great troubleshooting.
    I wish there was a repair video on the 'Tenma 72-6628' or 'Extech 382213' 5v, 12v, 0-30vdc 0-3amps Triple output DC power Supply. The 0-30vdc stopped working?
