"hmmm now where did I put that chip?" as he repairs another Dyson. You must already have a drawer full of extra chips you have ordered Mick. One of these days you'll be able to say. "I know I have one here. It's a good thing you have a good memory. I am sure I would have never guessed to check for a tilt switch. Thanks for posting
Thanks for the warning - I just assumed that 99% of mains -> dc was properly isolated. I kind of check for the cut across the board that they normally put in to show what's isolated. I do very little repair stuff so good tip for novices. Mind you - the whole point of injecting voltage is to bypass the mains section of the board so I'd always have it disconnected at that point.
Dyson are a pretty tricky company, they make some cool stuff, have really good advertising and branding and packaging, but as time goes on they use some mighty complicated little boards, wires that are routed in ways that do my head in. I have taken a part quite a few dyson vacuum cleaners, and reassembled even fewer. The older ones were tricky to work on but it was possible, the newer ones are painful. Apart from styling I wonder if they are any better. Henry is great for heavy sucking, G-tech make a pretty good sweeper vacuum cleaner. I'll stick to Dualit for my toasters. I don't know what my point is, but I can't see myself paying full whack for a dyson, not that I can see you doing that either! I put up a video today of a dremel repair. I thought it was the motor speed controller, but turned out to be a stator winding and a very easy repair. We will beat them! #righttorepair
Yeah I used to like Dyson stuff, but it seems they have gone down the route of cutting costs, and charging a fortune. I'll check out your Dremel video!
i disassemble at least 6 pcs dyson vacuum cleaners and do a deep cleaning. it is a pain esp, the suction head, so difficult to clean. the MOST stupid design in the world. chiNa copy and modify the suction area and make it easiler to clean.
Well done, conscientious repair. Sad to see these products fail in such spectacular ways (multiple components damaged) and even sadder for Dyson and many other manufacturers who are using cheap-as-possible manufacturing in order to maximise profits (which, of course, results in short operational lifetimes).
Thanks Ralph. Totally agree the quality on this isn't as good as the original cool fan I looked at. That one had a proper bearing and metal shaft that it rotated on where as this is just plastic with a plastic bush. Also using the motor driver chip instead of discrete components on the other fan. All to cut costs I presume ☹
Great video. Trying to fix an AM06 which is dead. Very similar pcb though the layout is different, I’ve put the two cap discharge resistors bback that have obviously been ‘removed’ by production engineering to save a few pennies. The inductor on the 5v? power supply has burnt out - not sure why yet.
Excellent disclaimer, you should have an even finer print saying if you can read this you are to close to the screen. Great to see that you got it working even if it's not the best of quality, and might explode at any time
Yes I am still here. Nice another Dyson fixed. As you say that orginal fault seemed to do a complete number on all of the boards/chips. Was nice to see you using the thermal camera that you fixed.
Just watched the video. I guess you do really know a lot and respect your patient too. Your knowledge of electronic way far better than me. I'm just a novice trying my luck servicing and repairing electronic devices. Anyway it's very educational and interesting. Thanks for sharing.
Something else you can check on PCBs with microcontrollers. If the controller has an external crystal (oscillator), check with an oscilloscope that it's actually oscillating (has started). If it was damaged, isn't receiving start power, caps have shorted, etc. the microcontroller won't run. If the crystal or surrounding circuitry (typically fairly basic) are the problem, you may be able to replace them and get the controller to start again. Not saying it's common. Just something else to throw in your bag of tricks.
Thanks for that. I've already done pretty much the exact same thing on other repairs such as the RGB laser, or the AverMedia video capture device that I also repaired 👍
So in case you haven't noticed yet the Ground of the Diodes are marked on the silkscreen with a wider white area.. Love your Videos I thought I would point that out incase you didn't see it on the PCB. There are other markings that can show the Ground band side however on that PCB you were working with when you were testing the Diodes I was like turn the Probes around when I seen you had the red on the side with the wider white line area. Again thanks for all that you do it helps me give my friends someone to share your videos with so I don't have to make repair videos.
Thanks Revo, yes I know about the white stripes on the diodes and pcb indicate the negative, I've just always checked them in both directions. I think I possibly had one once that had leakage in the opposite direction once as opposed to being fully shorted. Thanks for the nice comments. I'm not an expert but I've fixed stuff for years just not on TH-cam until about a year ago 🙂👍
Really good repair Mick and thank you for being a gent on the other repairer (wink wink). Interesting to see the voltage on the ground of the 5V regulator in relation to mains ground. Off to watch another vid 👍👍
No problem Vince. Last thing I would want to do is criticize anyone so I hope that came across in the video. I was just trying to explain to people that you can easily come a cropper and damage equipment or yourself and just to use extreme caution. I've had a few belts myself and also blew stuff up too! You learn from experience I guess.
Brilliantly undertaken, excellently fixed, you’re very methodical makes a great video too, keep up the good work. (here’s a laugh for you) well I did something stupid I was fixing a Samsung Tv ( that’s what I do ) and I suspected caps on the power supply, I heated up each cap in turn with a soldering iron, until I touched the top of a cap on the hot side, my god I nearly chit my pants sparks flew and what a bang…. All the electric went, it took out the boards fuse, I measured it and it was on the reservoir caps side so 330v down to earth through the soldering iron lol
I had the exact same model and the exact same chip spoilt. But after I replaced it , the fan still unable to run even when I have 5v. But I like to suggest to you to have a tungsten bulb in series to prevent any accident shorting... to protect yourself..
Hi Nick, is this something to do with the WiFi? I did a quick search and found this. Not sure if it might be the same problem? www.reddit.com/r/dyson/comments/ri78v8/dyson_tp07_purifier_wifi_issue/
Thanks. I need to improve the audio next. The in built mic isn't very good, so I cobbled together a jack plug with a bit of a mic from an old gaming headset 😂😂😂
Before I buy anything now I ask about spare parts , service manuals, schematics etc! If there’s none I just don’t buy! They always say we will replace it under warranty! I always say there is so much waste plastic now in the Oceans it covers an area twice the area of France!😂
9:57 But his power supply was isolated from mains (on the power supply), wasn't it? Or is the PSU's ground connected to earth? I get what you say after, in the case of the scope, you'd trip your GFCI. Or worse. But the PSU, though, I don't get it, unless the PSU's ground connected to the earth but why do they do that?
His power supply started showing a different voltage on the display to what it was set to, so it didn't like it. I wouldn't have taken the risk myself.
Awesome, I have never come across that chip before or that mains set up and I would have done the same as 'Buy Great Mince' (wink wink) so thanks for that but I stay as far away from mains stuff as much as life permits....cheers.
I'm a huge fan of your work and watched almost every repair video, but if you warn your viewers to be careful with working on PCB's connected directly to mains, why not using a 1:1 isolation transformer yourself then?
I haven't got one, they are useful for using things like a scope, but potentially don't make equipment safer to work on. You might find this interesting: sound-au.com/articles/iso-xfmr.htm
Again if you could find a Dyson hot cold unit model number Am09 with and h2 error code on the display and figure out how to fix that it would be wonderful. I think you might be only one of a few who could.
I haven't, I would have assumed it would be protected. I'm not sure if I've got any hardware that would read it. Agree it would be handy to have if anyone else needed it.
Hi again found this tested and completely dead ut struggling to find one could you help its right after the power in on the board if u zoom I. You can see the writing on it if you could help would be great sorry can't to put a pic of it on lol
Completely worthless device. Advertised as a 'blade less' fan, but it does have blades in the base. It's is just a gimmick to get people to buy a fan thinking it is "MAGIC".
Unfortunately it seems all Dyson equipment, our bad experience was with a "Tornado vacuum" of theirs that clogged so easily (was only good for dust nothing else, dirt, forget it clogged right up). Dyson is over engineered, way over priced and performs abysmally after just a short time. The fact they use a component to direct drive to the motor instead of driving a relay or triac screams rip off. Never a Dyson product will inter my home again. They are over engineered under performing very poor value for the extreme price point the name demands.
I have no faith in Dyson products. They are way over priced for an okay product, but not something I would waste my money on. James Dyson has been steering operations towards Asia for a long time. Back in 2002, he shifted all manufacturing from Britain to Malaysia. Dyson has plants in Singapore, China and in the Philippines. While I understand the need for lower production costs, I'd say he cannot call his products British made. You need to maintain 50% of production in the country of origin to be able to say it is made in that country. From what I've been reading and finding out, not even 40% of Dyson is produced in Britain.
It is no wonder that Dyson are scaling back and making redundancies in the UK. It's products are cheap unreliable tat. Yet massively overpriced for the purchaser. Avoid buying Dyson....they are poor value for the prices that Dyson imposes.
Unfortunately a lot of products these days lack in quality. I bought a kitchen aid food mixer a few months back and did a video on fixing a few minor issues and did a full strip down and rebuild. It's built like a tank and in really good condition, and it's 36 years old! I doubt you would even get anywhere near a mixer lasting 36 years these days..

Cheers Neil 👍I need to sort out my chips / parts to be fair. I currently have a cardboard box with loads of random chips, diodes etc in it.
Oh, well done! I am glad that the donor parts helped. This definitely wasn't an easy repair.
Thanks very much! Really appreciate that and thanks again for the parts! 👍👍 It wouldn't have been possible to repair it without them.

Yes it's quite easy to get caught out. A 'rough' way to tell is that isolated supplies have a transformer of some type.

Doesn't sound good. Hopefully it's not the main IC that has been fried.

Do you know where I can get one of these boards?
Mines blown and need another to repair my machine.
Unfortunately not, I think Dyson discontinued them. You might be able to find a used on on Ebay or such perhaps?
Those Dyson products are super hyped and priced to match. I can buy a simple ceramic heater fan for 1/10 the price of a new one of those.
Yes, agree and it will probably last a lot longer too!
I quite like the styling of these fans but the price has always put me off. Now if I win the lottery jackpot, I wouldn't touch one with a barge pole.
😂😂😂😂Yeah it was the wife that liked the look of them, I'd never pay the price for a new one, and they aren't that great.

The best thing you can do with a broke Dyson product is bin it and buy something else. Over priced cheap garbage.
