If I was this customer, this is a video that would please me. I wouldn't be happy with what was found wrong with the replacement power supply, however I would be very pleased to see this video documenting the quality of the repair service finally being performed by a competent engineer.

I agree. This should be the new standard for customer service. Although not an electronics theme, I have had my roof leaks repaired about 3 times. Never did any of those companies show the before and after BEFORE covering everything up. On the 4th leak repair I used a different company. This company took everything apart, took pictures of all the damage. Then sent them to me. They explained what they believe happened in the previous repairs (poor repair work and concealment of work performed). They then provided the estimate to replace all damaged roofing components. After replacing all the components they took pictures again to show what was replaced and repaired. After this they covered everything up and completed the job. Excellent quality work from beginning to end. That's how Mr. Carlson does his work! The best to his ability and leaving no stone unturned. I once worked with an industrial repair man 20 years my senior when I was about 23. He taught me to work like this! Be thorough in everything you do! Great video as always Mr. Carlson!

ever heard of single electron theory? There is indeed an object that could interact with all points in space and time from a single point in it's own space and time but struggle to exist in the same point in space and time. And it would be a single electron in a higher order space then our own. A higher dimensional plane. Viewing an object of such dimensionality would also likely create the weird observations we constantly note around freestanding electrons. The way they tunnel quantumly and can become entangled across space and time. The way they seem to blink in and out of physical/waveform existence through mathematical principles of uncertainty. Theres a legitimate possibility there is only ONE electron, and we are simply viewing the results of a SINGLE higher dimensional object intersecting/interacting with our own space time. There is an equal possibility there is only one photon as well. considering the geometry of propagation of photons in relation to phsyical matter in our space time. and time itself being a by product of the propagation of light through the vacuum of space. From the perspective of the photon itslf, existence is timeless, and it left source the same instance it's journey concluded and the process was instantaneous. Instantaneous is a concept a human mind cant even fully comprehend on the same order of the concepts nothingness, or infinity. We still don't even know what electricity even is at a fundamental level. Just how to manipulate it. Most electronics engineers dont even full grasp that the electrons are actually moving negative to positive at like 1 inch per second as an external magnetic field this produces around the insulator transfers energy at nearly the speed of light from [positive to negative polarities. You just have to contact this slow moving electron flow while grounded, or putting load on the circuit of electrons to access the energy in this field and this has a big part to do with why the dielectric insulator of a wire controls the rate of energy flow. The electrostatic capacity, and electromagnetic properties of the insulator are in control of this largely. As far as i understand, The only place in a circuit electron flow is the only energy carrier is the freestanding electrons flowing inside a vacuum tube. And at that point, although far slower then the speed of light, the electrons are still flowing fast enough to amplify oscillations in excess of 500,000khz accurately. This is not the case in a copper wire, you can run faster then the electrons flowing through a copper wire. They have to physically move through physical holes in the crystal lattice of a conductor at the quantum level. In my own mind i perceive the electromagnetic flow of energy, kind of like the wake these electrons produce through the process of finding their way to a positive polarity if there is a way to do so. If theres a way to the positive charge, they will find the path that get's them there, positively charge one end of a circuit through a conductor, and you have given the free electrons a path to positive charge, and their "wake" creates a path for electromagnetic energy to flow. The energy transferred and release through the wake of a boat is carried on much MUCH further and much more quickly then the individual molecules of water are actually moving or transferring energy wise. It's not a great metaphor, just the best one i'v been able to come up with to form an internalized understanding that feel accurate enough. water is something that behaves physically as both waves and particles, and transfers energy incredibly quickly so it tends to be the metaphor i make. Before a tsunami wave hits the continental shelf, it can move at nearly 1000mph and it's not even a centimeter tall, but we all know what happens when it hits the shallow continental shelf (the load on the circuit) Depending on how much energy was released, and the load put on the circuit.... etc etc. etc. The water in between barely moved, didn't do much of anything at all, but in doing so transferred staggering amounts of energy. Electrons react very similarly to water when you try and squish them together with energy (positive charge on a completed circuit with load), they move a tiny little bit, but in doing so transfer staggering amounts of energy down the line to the load, at equally staggering speed. Your electronics are not running on the electrons, they are running on the electromagnetic transfer of energy the electrons provide, and in a DC circuit, there are actually more electrons moving away from the load then towards it. Not trying to be a contrarian, i just felt like pontificating on this after reading your comment lol. You actually do not have to understand this whatsoever at all to be an electrical engineer though. And understanding it makes you no better with electronics either lmfao. If anything it actually makes them more bewildering, even when i successfully implement a circuit, and i know what everything is doing to the energy flow and why, at the fundamental level it's more baffling to me then ever. If i recall correctly, the double slit experiment wasn't a designed and executed experiment originally, it was just something someone noticed on the glass of an old vacuum tube with a focused electron beam in it performing a completely different task that had failed. The double slit was originally a discovery before it was an engineered experiment.

Hey Paul, Thank you for all of your switched-mode power supply troubleshooting and repair videos. It helped me a lot to get into repairing SMPS and other circuit boards myself. Sadly, my shack is not as well equipped like yours, but it works for me just fine. A big downside on my end is the required time to test, find, and fix damaged components on complex circuit boards, so kudos for your time and dedication! Please keep it up and post more videos of that subject. Cheers and vy 73!!

Hello Mr. Carlson my name is Don and I have had an active interest in electricity since the age of 4 and at the age of about 10 I started actively studding first vacutube electronics then at about 13 solid state electronics and I am trying to put together a lab on a shoestring budget so most of what I have is used and non working and I have a really good time repairing these items , and yes I like to watch your videos , I've been watching your videos for about 5 months now and I can see you know what you are doing , I am now 54. OH and your lab is most impressive .

Hi Paul, Not only CNC power supplies come without schematics. My main business is repairing calibration and test gear (incl RF stuff) but a lot of it is from industrial users. They also bring me other industrial stuff for repair. And that is the same problem, no information at all. Often not even user manuals. 95% of my work is without any doc I'm now reverse engineering and more or less rebuilding a machine controller/computer from 1984. That takes a lot of time but the only other option is replacing a very expensive custom build machine. Everything is covered with conformal coating, dozens of in and outputs that are still in the machine, unobtainable/obsolete parts etc. To be short a lot of fun. I always like your repair video's to learn new "tricks". I regular repair secutests and that involves a lot of relay testing. So your video about your relaistester was very handy. I made a fixture for my Tek 576 CT to do that test. The stepper switches the relais. Can you make a video about how you do reverse engineering ? Fred

as someone who spent many years in electronic/electrical repair it is very refreshing to look at someone with the skillset you have , both theoretical a/academic and practical . A credit to you . I think that in a lot of cases like this the cost of the repair would be a considerable portion of the cost of a new board .albeit that they are still avaliable . 1st class work and logical approach .

Troubleshooting on complex PC circuits without schematics or voltage expectation on takes some clever methodolody and you demonstrated that very well. I was glued to my screen as you explained what the typical readings should be on some of the components that had to be replaced . The detailed explanations for their function and parameters of each component that was suspect. Your vacumn solder sucker mod was interesting too. Tackling replacement of a surface mount component is not an easy task, it takes the right kind of tools, a steady hand and a good eye with magnification and verification that that no pad are shorted together with a solder bridge. Fantastic demo of the skill and dedication and hours it takes to properly repair a complex board that most wouldn't even dare to tackle!

These things are everywhere and I often face a challenge unraveling the various feedback loops to find the actual fault as the psu often presents as tripping. This is even more difficult with microprocessor controlled units where the control loops include software control. Thanks again for taking the time to produce this content. I know it is loss making but you are providing a valuable educational resource and that is very worthwhile.

Great video and great troubleshooting Mr. Carlson. During my tenure of employment as an Electrical power electronic Technican in aerospace I was provided with great training of the power supplies of CNC equipment. This was around the early 1980’s when switching power supplies became popular. Switching power supplies are very efficient in comparison with their predecessor linear supplies. I take great pride in my ability as a technican and believe in applying my self in studying the equipment down to the finest details. This means understanding the quality and behavior of every single component. You have provided me with additional expertise in your excellent explanation and troubleshooting abilities. Love that desoldering tool you use and the multimeter that seem to have a temperature read out incorporated within the meter. Keep up the good work and keep these excellent videos coming.

Mr C, most people including myself make a repair and are flustered when it does not work. You seem happy when you get to troubleshoot some more.

Fantastic video Mr. Carlson. I really enjoyed this look into what you do for a living. I'm not sure if others have checked out your web site or know that this is your bread and butter industry working on these specialized power supplies. At least that's the impression I got from reading your site. I really liked the great lengths you went to describe things and to show us the steps. It wasn't lost on me that you showed us some of your desoldering and soldering! Yeah! It was great. I'm still watching so back to the video. Cheers.

¿No new resitor on started circuit? seems the oroginal is no crapy 1w s or less like on comercials psu but they used for dead on long range periods y used for put new for avoid problems like the started circuit cap.

Thank you so much for this very instructive video ! I am very surprised that a manufacturer install this kind of crappy capacitors on an industrial power supply. It's a really stupidly CARELESS design. I got a machinist course and visited a few factories. So, I know that CNC machines are working sometimes in a really harsh environment. Fortunately, it as not been installed in an aircraft. :-)

Paul, I love the CNC content. As a CNC tech performing maintenance and repair of about 100 CNC machines including 8 Mitsubishi's that use SF-PW's, these CNC power supply video's are awesome! After watching this video, I immediately checked the machines and 5 out of 8 have the original Nichicon PF caps in them. I've been getting intermittent 6B spindle servo alarms on 3 or 4 of them. It's normally as soon as you E-stop them, but I've got one that's started to throw it while it's running. I'm hoping recapping will cure the issue. Incidentally, I didn't see any signs of leakage on either of the 2 SF's I looked at. The MDS SF-PW is a different version so I pulled both versions and got a cap list together so that I can recap all of them. I'm using Nichicon PW series caps for the majority of them. I would be interested to know what part you change out the FET with. I'd love to see some Fanuc drive stuff. Keep up the great work!

Glad these are helping you Mike! If you don't have a test fixture, be careful of your work, you may harm the drive if any Voltages are high. The Mitsubishi supplies are picky with the capacitors, If you find it's "ringing" loudly in or out of the drive, part of the 5 Volt feedback will need modification.

This was one of your best videos Paul. I have worked on switch mode power supplies and most of the time find them difficult to trouble shoot because if broken it is difficult to start somewhere because of the startup circuits. You were very instrumental in how to do that. Looking forward to the FET video and would also like to see a complete series on trouble shooting switch mode power supplies in general, both theory and repairing. As if you have nothing else to do. LOL

My first dive into repair was a self-build windows style computer based on a copy/modification of a $2500 windows gaming machine out of a computer magazine. I had a tiny bit of experience with assembly, having built a Heathkit a high end AM/FM stereo kit and Heath's color TV while doing a medical internship. Reading the manual, checking off the completed tasks was very relaxing for me. Theory was another matter. The computer was easily assembled and worked flawlessly for 18 months. Then one evening it would not turn on... no POST, so it seemed to me that the power supply was not working. I was surprised as I had spent about $250 for a 600 watt supply. which at that time was PLUNTY. I had no fancy test equipment other than a good VOM. I removed the 8x8x8" cage and wires. When I removed the cage, one of the tall capacitors had a black soot around the base. It was de-soldered and there it was black soot coming out of the base of a lead. It was toast! $2.45 later, a clean up of the board, re-solder of the new Cap and I was back in business. Computer ran great for two more years until it was stolen. I am thinking I need to "enroll in your electronics class. Could you "ball park" cost of second hand test equipment for a fairly decent lab and the cost of a well equipped lab with top quality. (I don't want to waste my hard-earned dollars) on an emblem stuck on piece of equipment. Oh, I got my tech license years ago to give me access to 6 meters so I could fly R/C airplanes. Had to learn code and was right at 15 wpm, but got scared and just took the 5 wpm test. Later got my general. Do not understand much of the electronics on advanced buy I bet I can memorize the q/answers. Love your work. You are young. Long life possible. You will change many lives.
