Much as I love to see old stuff repaired, this could not have been a good financial option. A replacement psu/charger for that unit isn't much over £100, I bought one recently to replace a 24 year old one which went bang and threw bits of transistor out of the vents! lol. Eeek! Glad I discovered your channel. Fascinating to see how you can fix all this stuff.

Such memories. About 15 years ago, hmm, maybe 20, I was having my computer worked on. Came into the guy's shop to pick up my machine and noticed a computer on the bench with the power supply out. mentioned it to the guy and he said it was a common thing, and it was always just easier to put a new one in than fix the old one. I asked what he did with the old ones. He said "I don't know why, but I just toss them into a big box at the back." I asked to see it and there were about 50 supplies in there. I said I might be able to fix some of them and we made a deal for me to buy the whole box and he'd buy back the ones I could fix. Lots of shorted diodes and popped caps. Ended up fixing about half of them. I made a decent profit plus I scavenged a lot of good parts. Best were the IEC power plugs with noise filters. It was an ongoing thing; when he had about a dozen old ones he'd give me a call and I'd pick them up. Went on till he had to move away.

So Mark gets 300 early zee morgan. Reminds me of going to work one day. I had a piece of 440v machine and needed to tag it out in the control room. The walkway lanes were maybe 4.5 feet wide between control panels. As I started I set my coffee cup on the relay I wished to tag out. As I set the cup down the cup had spilled over making the paper wet and zap. I just caught myself before landing back against the control panel behind me. A valuable lesson to never do that again.

Hi Mark, sorry, but I had a good giggle and had to replay the 'shocking' part. Fuckin' pissed myself. 30+ years of repair experience here and I can confidently say we have ALL done it at one time or another. Reminds me of quite a few years ago one day working on a CRT television, I carefully reached in across the PCB to make a trimpot adjustment resting my hand against a tin EARTH shield (to steady my hand/arm) as I did the adjustment, turned my head to look at the oscilloscope while adjusting and just barely brushed my finger against a LIVE heatsink and pretty much said the same thing as you. LOL! Certainly wakes ya up 'ey mate. Silicon handles electron flow so much better than us humans. Lol!

When I was an apprentice (many, many years ago) one of the engineers spotted me discharging a capacitor with my screwdriver. After giving me a bollocking, he picked up a resistor and said; 'This is how it should be done'. He then proceeded to bend the legs of the resistor, and holding it between thumb and forefinger - BY THE LEADS - he touched it to the capacitor terminals! After watching him jump violently, I said; 'I think that I prefer my method...'

Your videos are fantastic - very detailed and complex repairs with amazing attention to detail and workmanship, as well as a great presenter to boot - I'm hooked! Spicy caps are no joke. Took apart a Sony VAIO laptop power supply thinking I could fix it (no idea why I did this, I clearly could not) and received enough of a belt from a large cap to burn a nice little hole in my thumb that hurt for weeks afterwards. Charged caps - not even once.

I've been binge watching your videos for a while now, Mark, & I always had it in the back of my mind that eventually I'd find "the one with the shock" as a certain US sitcom would say. Lo and behold, today is "that" day! In all the many, many vids I've seen, this is the only one I have heard you swear! (Lol) I've seen you drop things, forget stuff that meant you had to repen a case with 1000's of screws and generally do stuff that, if I'd done it would've had the air blue! For you it took a big jolt of electricity to let out a standard reaction 🙂! Unless you are really good at editing, your powers of restraint border on the superhuman!!😂😂. Anyway, as I'm sure you can tell, I really like your videos. Sadly, I can't afford to join the "Mend It Like Mark" gang, so I hope you don't transfer all the good stuff behind the paywall, and you will continue to provide the same quality of video on KZbin. Cheers!

Ow! I felt that. Those HV caps can hold charge for days. I've had a16uF / 500V electrolytic sitting on a shelf for 2 weeks here. Put it there fully charged and measured 235V next day. Down to 187V 2 days later. Just measured it again now, (2 weeks later!). 7V still lurking in there. Soakage may be a factor as it's a tad old. V test every time. Thanks for the excellent content. I like the DC current limit test. Series light bulb and variac still here. Most appreciated. Cheers. Liked and subbed.

It reminds me of the olden days when I used to service valve (tube) TVs fitted with cathode ray tubes. The final anode (plate) of a colour CRT required about 30 kV to operate and I had an enormously long probe to check this voltage. The final anode also acted as one plate of a capacitor, still retaining its charge when the TV was switched off . So the first thing to do before anything else was to discharge this anode using an earthed conductor such as a thin screwdriver. Invariably there would be a sparking noise showing it was now safe. But it was so easy to forget to do this especially after having turned the TV on and off several times. Fortunately, although the anode voltage was high, the current behind it was fairly low so you only felt a medium jolt, but you also felt stupid! In more modern power supplies it's good practice to have in position a high value parallel bleed resistor, say 1 megohm, to discharge any high capacitance electrolytics when the device is switched off.

Reminded me of an incident many years ago with a PSU out of a big CRT TV which I had been working on. You were lucky it was on the bench when you did it. Unfortunately I was picking mine up off the bench and my muscle reaction meant it went flying across the very large workshop ending up on the floor with a few cracks in the PCB. So easily done now matter how many years you've been doing this stuff.

Its a great fix, but when you consider the price of a replacement PSU is about £40 (not including shipping), when you add up the cost of the replacement parts and the labour cost for fixing it, you can see why most electronics ends up in a bin rather than being fixed. It is good to see the skills being put to good use, it's just a pity that there is just so little opportunity to make money out of electronic repairs these days.

9:40 That's something interesting to know. Cheers Mark 👍🏻 I love learning hand bits like that. I've got one of those multi component tester's, but it's a LOT easier and quicker when you're already using a tester. Obviously it won't check it the same as a proper tester would. But it's nice to do a quick check just to see if it's shit the bed or not. 17:53 Your completely right Mark. You could buy a specific tool to discharge cap's, but it also costs money which you could of used buying USEFUL tool. But what you could of used to discharge cap's AND to save money buying the tool in the first place. Is anything metal that your not too worried about, if it ends up with splatter mark's or chunks missing out of it. Like a screwdriver or an old pair of pliers. It's very quick, and very cheap. As your already using something you've already got. 20:20 Now THAT looks like one exspencive scope you've got there. What's the GHz?

Mark I have to tell you one time I was trying to test an Old Ham amplifier that was modified to be used on CB radio and it had a 3-500Z tube which would put out about 800 watts. It had about 2,000 AC plate volts, but I am just an amateur so don't quote me on this. Anyway it had an RCA jack in the back for the foot switch, but I was just using a short piece with RCA jack on one end and other end stripped bare. I guess I was sweating a bit and somehow my forearm touched the case and it jumped into me. The next thing I knew I was standing about a foot or two back from the unit with my fist clenched and smoke coming off my arm. Talk about a wake up call I mean I was in shock 🤣🤣🤣🤣🤣

What a coincidence. I've just today finished repairing and refitting a Sargent EC400 to an imported caravan. The caravan had been in a flood and had been swept against a fence. Unfortunately, the battery had been connected and all the electronics were damaged. The charger/PSU was also a Mean Well, and was relatively easy to repair, but the relay board was a mess and had been burnt. It is a rubbish design; solder mask is black which makes reverse engineering very, very difficult, the relays are marginal for the current they have to carry and the keepout is ignored (solved with Kaptan). The RCBO and MCBs were stuffed of course, but that didn't matter because they would have to be replaced with ones of higher standard as required in our country. On the processor board the only thing that needed replacing were Electros, a poly switch, a couple of buffers (SMD ULN2803A), a few tracks. When I'd finished, I tropicalised the boards. Why don't all manufacturers coat their boards? Anyway, best wishes. I really enjoy watching your repairs. Keep up the good work.

Looking at it, it definitely had PFC - thats what Q1, those diodes and the first yellow transformer (actually a choke) was. Active PFC seems to be a real weak point in modern SMPS's - especially if the main storage capacitor is bad quality... the PFC will attempt to ramp up the voltage until it eventually turns the transistor on full - shorting the supply when it does! Seen this on loads of LCD TV and monitor power supplies.

Leaving in the things that went not that good (getting the electric shock) alone is worth the abo and like - just as a nice reminder to always stay safe, not because of failing on something, that would be unfair. I also got zapped by about 3 kV when I was measuring in some pretty old CRT with thyristor HV stages and it left some nice "shot" into my finger. Nice little black carbonized "current channel" and white, "cooked" flesh channel of about 2-3 mm around it, which is not exactly what you want. Afterwards that happening I *knew* why it was a good idea to intentionally leave my other hand in my trouser pocket when doing that measurements, because that way the current could only go through that one hand measuring and not through my heart! Things like that are not that easy as they look on video - they can (and will) destroy nerves, if the current goes through inner organs it can leave serious destruction *inside* where it can not be seen. Stay safe - nice work and good videos, @Mend It Mark!

Anyone who has worked in and around mains equipment before knows _exactly_ what the "sideways" gaff was about. Once you've had a belt off something like this, it makes you kind of petrified and paranoid about mains equipment for the rest of your days, no matter how experienced you get. But every once in a while you just get that _little_ complacent, and a big fat D.C. reservoir cap is going to be waiting for the day that happens, so it can remind you who is boss.

By the way, in my first job there was a tech in the workshop who would take great delight in getting a loose D.C. reservoir cap and charging the shit out it, and then as you were walking passed he'd shout "CATCH!!!" and throw it at you. Of course, your natural reaction is to try to catch this airbourne object. But then you realise, mid catch, what has just been thrown at you. And you either shriek and jump away like a little girl, or it's too late for that and you get a belt. Man. H&S would have a field day with stuff like that now. Probably for good reason 😂

I have enjoyed your videos for some weeks now because you exhibits a great sense of humor (American, can you tell by the spelling?) but when you got shocked and exclaimed "fuck me sideways!!" @17:56 I laughed so hard! 😂 Great video and you have a wonderful, entertaining and humorous way of dealing with things. Good work!

When I worked at Apple back in the 90's a great trick was to charge an AC adapter (no cover) unplug it and then say to another tech, catch ! :)

Hi Mark, ive got to say mate, i love your vids and your personality tbh. I just wish i lived closer to you (im in Pontefract), as would loved to delve into your infinite wisdom of electronics and extend my knowledge, as i love learning when it comes to electronics. I do tinker myself, mostly with laptops, phones and tablets etc etc etc, just to earn a bit of money on the side and help friends out, but i dont know anywhere near as much as you, as all mine is self taught, starting from when i was about 4yr old and im 44 now, so ive learnt a thing or two but nothing to your level :) Ive got to admit though mate, your reaction when bridging the capacitor had me creased :) lol sorry bud, but i know that feeling all to well, and yes it certainly will wake you up hahahaha last thing that got me like that was a camera flash unit, which gave me a nice tickle, and resulted in the camera being launched across the room lol. But yeah keep up the good work mate, as i love your vids and your attention to detail (borderline OCD) matches mine exactly, so i always agree with your comments :) Ive binge watched just about all your vids now, starting from your latest ive got as far as this one, so not too many more to go Ive already learnt so much by watching your vids, so thank you for that! :) ive just subbed too! :)

Hello, great vid. I'm curious why you tested it with a DC input? How does that work if it's designed for AC. Is the mains going straight into a bridge rectifier?

Yes D/C straight through the bridge . Also most switch-modes will fire up on 80 volts a/c . At work we used a small custom 40 - 0 - 40 transformer for fault finding . ( it was limited & the 0v ct was used as the ground ) .

Reminds me of my brother-in-law poking around the back of his old B&W TV. I asked him, "Do you know what a capacitor does and looks like?" He just gave me puzzled look....

So glad I subbed to your channel. It's a pleasure watching you work. Now we gotta get Mr. Carlson to start yelling "fuck me sideways" and the world would be perfect.
