Re: Any practical examples of success repairs
to add to sti's comment:
open resistors, or resistors that changed value outside the tolerance. PWMs that don't switch. Blown up gate drive circuit (when the Mosfet is shorted).

Re: Any practical examples of success repairs
Some of these channels have SMPS repair beyond the simple bloated capacitor, but none that are dedicated.

Any practical examples of success repairs
Are there available( anywhere) any successful repairs of switched-mode power supplies?
I found a few on YouTube but they were rather simple( e.g.changing dried capacitors ). I would like to see( and learn)how to solve more serious faults and not those trivial ones that can be seen at the first look.
Thank you.

Hello from France,
mon2 kindly advised me to post a thread to ask the question(s) I'm concerned about. I'm new to the forum and I'm looking for practical courses for troubleshooting pc motherboards especially laptops in Europe, if possible in France. I have been a computer network system administrator and a corrector of administration modules for automated programs under Unix. But I really miss the practical "ops" side of troubleshooting. So I would like to start from the beginning: 1.8V, 3.3V, 5V and 19V tests for example, etc...
Do you think this is feasible for me? I... -
Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.
Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting... -

To save you some time: the most important bits are in bold.Some further examples/explanations or to the side & in grey - you can probs skip them if it's TLDR for you. Sorry, I've got ADHD & tend to over-explain stuff - just like I'm doing right now 😅 Briefness is for poets not me 🙈
Please help!! 🎶I'm just a girl in a world that wants to scam me out of lots of money for any tech stuff/repairs 🎵 Seriously tho, I'm poor&I can't afford to get laptop diagnosis, especially if it ends up needing a new motherboard.
Where I live, all the tech shops are run by very...

I was watching a YT episode from Nick's TV Repair and he literally had a test jig comprised of all the internal components of a TV on a wooden board.
I thought that was amazingly smart as I always thought that TV repair businesses had a room of various actual TVs they would use to do testing.
My question is how was he able to connect this generic looking external display to the jig? The connectors are intentionally covered up by cardboards so we cant see it but i wonder if its a custom in-house device or something that could be purchased online?
