One of my favorite things about My Mate Vince is you never know what he's going to try and fix

The bit at the end was brilliant . more please

The skit at the end had me laughing, nice one Vince.

I’ve got one of these. They’re more painful than the original back pain 😂

Fantastic job lol =D Loved the result and funny testing process at the end =D

@@Mymatevince The circuit you got your hands on here is called a Full H-Bridge Driver! With those 2 complementary Mosfets it was instantly clear to me.

may be the mosfet burned out because of the loading on the motor, so resting or pressing your head hard into the massage 'thingies' partially stalled the motor(s) and the rising current overloaded the mosfet(s)🤔

I would suggest the high resistance on the ‘loose’ head overloading the mosfet

“I’ve got Cucumber in my eye” 😂😂 great job Vince.

I suspect what may have happened is that screw that you found turned itself out from the turning of the motor, that side was then not making a very good connection, it was possibly connecting and disconnecting over and over and this caused a build up of current across the mosfet which caused that catastrophic failure. Great vid as always Vince!

I really enjoy these repairs on weird junk. It's fun to see how they work (if at all) and the repairs you figure out. The little skit at the end was the icing on the cake. thanks for a fun video Vince!

Im really glad you went the copper tape route . Besides the wonky height issue , that was a beautifull trace repair . Deff much better then jumping it ... and while its true no one will ever see it most likely . Its nice to know you did it and you did it right ... and if anyone else ever did get into it the future im sure they would be impressed to see the great repair work that has been done previously . Plus its good practice . Side note ... you should get some sort of custom my mate vince soldering iron tip ... to brand the inside plastic of items your work on ... as a sort of signature incase one day someone does do a repair on something you have worked on ... would make for a cool little easter egg

Just thought - you could probably use the grinding pen to flatten the solder blobs on the copper strips. You did a good job, I’m impressed.

Cracked me up real good at the end there 🤣🤣 Your videos just keep getting better and better mate!! Absolutely Loving your work!!!

Great job! Love your content and you've helped me have confidence trying to fix things like this.

I was given something similar as a gift. Where the lights are, they were colour changing leds, the heat was geneated by overpowered resistors stuck on a circular aluminium heat sink. The plastic moving discs, were made of a gel like rubber. Used it once, now in the understairs cupboard amongst all of the other useless gadgets.

Must admit, even though I have been a huge fan of Vince for years, it was the list of problems and Jim's appearance that I instantly decided to join the patreon. Couldn't help, but laugh. Long Live Vince! Thank you for inspiring me to get into repair myself and I look forward to your future videos.

So pleased I watched this, I have the exact same model, so if it goes wrong I know what's up with it lol 😆 I love mine x

I've had the same problem, with me both MOSFET blew. But strangely it works with no other features. Thanks for the video Vince, it's been a great help.

Cool! I have the same one, but with a back cover. Now I know how to fix it. Mine still works.

Love your videos!!!

Good job mate 👍

Excellent fix. Love the end 🤣🤣🤣

All I can say is, your copper connections were much neater than any I have seen on other videos. Awesome job!

Didn't expect it to use MOSFETs to do the switching would of thought it would have had a cheepy micro or MCU. Interesting none the less well done Vince.

"I've cut my cucumber too thick" -Vince, 2023

What are the advantages of trench MOSFET? Advantages of the trench design include 1) Lower ON resistance, 2) Smaller parasitic capacitance, and 3) Improved switching performance. One drawback, however, is reduced short-circuit tolerance due to the lower ON resistance. "reduced short-circuit tolerance " Screw drops out , short circuit , boom

Good video again 👍🏻

"The Thumbnails" agree 💯

Massager? Probably The most random thing you've fixed (Edit) Thanks For The Heart ❤️ Vince

I actually laughed at the end. Thanks for that. And you are right.... It IS a race to the bottom !

You're right about the n- and p- pairs. They make an h-bridge, which allows you to swap motor direction.

Got a foot massager with 'broken heating' for cheap. Heat is generated by a few light bulbs, and all was working fine. You cant expect a foot sauna when a 24V 2A power supply also has to run a high torque motor.

A clean bevel tip is great for flattening solder joints. You can just drag it across the joint and it will collect any excess solder(within reason.)

Nice save on the board..... I suspect that the bolt fell out of the head and shorted out the board. That amount of burnt material is indicative of a direct short circuit.

I'm building a cool project at the moment, I am converting a six grid watch display case I got from Lidl's to become a solar box so I can keep my solar and eco-drives charged up. Going to run a set of UV's facing pretty much aimed at the watch faces using LED strips (bought a shedload of different types including UV, colours and multicolour on rolls from Aliexpress a while back) and a power brick off of something broken and these rolls of LED's are cobs so all I have to do is supply power, all the resistance etc is built in. The power brick I am going to use is actually a variable output, I am prob going to put a row of warm white to "backlight" the watches and if that looks good I will prob do the other display cases. I am also going to do something similar but using QI pads from Aliexpress to charge my Kinetics up, going to see if the solar bit works first.

I was expecting the adhesive in the copper tape to melt off as soon as you put the heat on to it.

Great fix, i have one myself and are good, but you do know your suppose to put your arms . forearms / through the wings and put it on your neck while sitting upright , ... try it you might like it ..

Ooh new trying to fix video

Can't believe the heaters are light bulbs...well... Complementary transistors are pairs of opposite polarity, mostly used on class A/B and B amplifiers. How they are used on the motor drive is known as an H-bridge. Used for motor directional control indeed! "trench" in transistors is the manufacturing process. There is an actual trench on the silicon! Done mainly for more surface area.

7:00 I would've thought there'd be one for each motor because someone had disassembled one motor so it was likely the mosfet for that side, the 3rd one is likely the heater

I didn't notice whilst editing but just watched it back now. I do have 2 powerful studio lights shining down, one behind my right shoulder and one to the front left of me. I think the plastic must have been slightly shinier on some bits or maybe not perfectly flat and it just reflected the studio lights when I moved it. Well spotted though Marcel. I do like the idea of sitting full weight on it and seeing how the long the motors or Mosfets would last, could be a revisit video 😂👍👍👍

Pretty much from the moment you got it open I was pretty sure I knew what had caused it.. Probably one of the rotors stalled, stalling the motor. That caused an over current and the overheat. The loose screw is definitely a suspicious candidate in stalling the rotor.

I've the same massager and it keeps cutting out every time I try to apply pressure - was hoping the video might give an idea, so not sure if it was the pressure point related?

Vince I have never seen anything that came apart so easily for fixing, what a brilliantly designed device. One zip and all the intricacies of the device are revealed for fixing just wonderful. Did my eyes deceive me or did I see something shorting out when you moved the device.?? I have to ask though doesn't the heat come out of that other plastic cover the one with the slots in it, it looks like a heating element underneath it?? Just a thought. To be honest it looks like a peltier chip or some other heating device underneath it, well it looks shiny anyway.

Really easy to take apart, the easiest thing yet! I think that was some weird reflection of light because I have a big studio light shining right down on it. Unfortunately it is just the incandescent lights giving out the heat or should I say giving out a glow😂

love it haha too much pain haha

I laughed at the end that was entertaining 😂😂😂😂

Hey, I have the same device. Newer version, since it was bought new in the last year. It has stopped turning on. I have confirmed the power is getting through the fuse on the board, and there are no obvious burned out components or solder joints on the main PCB or switch-board. Any ideas?

cant see it somewhere but these 4 mosfets creats an H-bridge to controll the motor like you said

seems like it, the chip version has 2 on each chip

Those things are a pain (in the neck.... i don't apologise), we had one and one of the wires carrying power was just in the wrong place and kept getting pulled out of the solder. I even put an extension on the wire to no effect, same breakage kept happening. So annoying as its really good.

Great ending 🤣

Dinner and a show, who would have guessed...lol

I bought one of these on Amazon, I then spent £500 on Osteopath appointments recovering from it.

How do you charge it the charger doesn't plug in unless you push on it as hard as possible?

I knead to get me one of those.

You should call the 20+ minute videos "Fuse repair Shorts"

If the MOSFET was the same as the other on the board. Would it have been easier to just see where the 2nd chips legs went to, when trying to work out the tracks that were missing? I would think it was connected to the same value resistors and such or was it setup differently?

I have a very similar one but it doesn't have the straps. Bought it from Lidl to ease a strained muscle in my neck and it actually made it worse although it felt kinda nice. My neck made clicking sounds when moving my head around for about an hour after using the thing and it didnt fix anything pain wise. Absolute waste of money.

I have one of another brand, another color, exactly the same. The heating is a joke, it's obvious when you realize is powered by a 30W wall thingy. I think mine has leds instead of the incantescent bulbs, it's more the heat from the rubbing than from them.
