This is the kind of fix that makes our brains understand the logic and routing of the circuit; I am getting smarter with each fix. I know what sort of pressure you are under with the schedule you imposed on yourself, but the variety of fixes are widely varied, and like a fun mental game for us to follow along, and VERY practical, so know it is appreciated. Next time maybe do one every couple or three days, so you are not so stressed. I do a LOT of repairs of 'stuff' like you demonstrate, and in some ways I am more skilled, but I am amazed every time you tear into something electronic, so we can follow along with your train of thought. Give us an update when the dual mosfets show up on this massager. And propose another fixathon of some sort early in the new year: we are like Pavlov's dogs "ooh a Vince video" drool drool 🤤🤤
Hmm.. two p and n channel Mosfets.. so most likely they make a h-bridge. I wonder if the motor would change directions after some time. With your bodge wire that would create a nice short.
Well done Vince on another epic release, was worried that you might not make it today. Great series. Thanks for all the videos. Getting me through a tough time at the moment.
Wow Vince. What a man. I cannot tell you how impressed I am with your patience, tenacity and powers of deduction. To be able to get out all those videos in the alloted time is good, but to have to rely on diagnosing the cause then fixing the fault is amazing. If you were only my next door neighbour, I'd never stress about anything again. Well done and you have made my Xmas very merry indeed
Nice job Vince! For future reference, resistance in with resistors in parallel is calculated using the inverse sum of inverse resistances. In your case, 1 / (3 × (1 / 0.68)) = 0.227 ohms. You would've needed over 13 of these resistors stacked on top of eachother to get close to 0.05 ohms 😂. That would've been a spectacular resistor tower lol.
Well done vince maybe you should take a break after tomorrow and enjoy Christmas with your family i don't think anyone would blame you you've certainly earned it mate amazing series loved every one thanks vince whish you and yours a great Christmas 🎄 🎄🎁🎁🎁❤❤👍
that chip is a capacitive touch sensor controller with an I2C interface, so that's most likely where the signal is going. The reason it's acting funky when you touch the spring directly is that you're overloading the input- it's designed to sense your body capacitance through an insulating plastic layer, not directly.
Good to see your back Vince 👍 hope have wonderful day on this Sunday evening i appreciate all your time your com back to do amazing Videos for us to see you doing today enjoy your rest of your day your and family Thanks your so much
No, _you've_ been fighting sleep after a tiring day but refusing to go to sleep until you've seen today's Advent fix... Just want to say again how much I've been enjoying this series, Vince - thank you. And only two more videos left, after which I assume you'll be sleeping until January 😄😁
Hahahahaha, it was a close one today. Yep I'm looking forward to the end now, relaxing and drinking some Baileys and the obligatory Christmas Monopoly session!
Thank you so much for this marathon, Vince. For me, it really helps with relaxing in the evening after my job. I really appreciate that you sacrifice your sleep for our entertainment. I hope you'll have a very merry Christmas!
Wow! You managed to massage the fault out of this one. Thanks for a great series. You deserve to get this fixed, so you can spend a day not fixing but relaxing. Best wishes from the USA!
We’ve all stayed up too long to miss the obvious Steve - if you weren’t tired as soon as you proved the motor , the obvious thing is to prove the mosfets. Merry Christmas keep up the great videos
This happened to me while fixing a TV box. The board was fine and it was getting enough voltage but it wouldn't turn on. Tried my bench PSU and it started working. It turned out to be a faulty capacitor in the power brick. I was getting voltage reading but not enough amperage probably.
ive been loving the daily videos, def something to look forward too. It has to be rough tho and i am already preparing myself for no uploads for a little bit while you recoup. On the road to a million!!
Had one of these massagers, and the valve failed. It didn't let the air out, only pumped more in. I actully panicked a bit, when I couldn't remove my feet from it. Replacing the valve fixed the issue
Hi Vince I think you may have jolted something back to life when you made it spark with your tweezers. My sky box stopped working years ago. I accidentally shorted a transistor with my multimeter prong and it came back to life. Not sure though mate. Love all your content hope you have a smashing Christmas.
it has been amazing watching these every day my autistic son loves your videos hes been watching you for years he has a problem with his temper and smashes things up your fixes calms him down hes a big fan i also keep saying i will send it to vince he will fix it lol
You should look at adding a decade resistor to your toolkit -- they allow you to dial in the exact resistance you want. They're great for lab-work and diagnostics/testing!

Just got back in, my "Doris" is all legal and fixed and now running about in the old girl and locals are happy to see my 3 wheel van back on the streets yay :)
Good stuff sir, you going round the houses till 3am before checking the basics of components is why we tune in 😉 you mostly get there in the end and learn/provide some really good insights. My kettle gave up today, having a little tip in my head from one of your old videos - the first thing I checked was if the two connections down in the base were pushed up enough to make contact - low and behold.. ☕️ Get that thing on your calves by the way 🧐
Please repair a lightbulb and battery tomorrow so you can get some sleep. Your ability to lead us through the thought process is fantastic. Happy holidays to you and to everyone trying to find true ground.
Hi Vince. I’ve been watching and learning for about a year now and love your videos. I have purchased a lot of equipment and have done my first repair a week ago and the feeling of fixing something myself was brilliant. Thanks for the inspiration. Merry Christmas from Roger at magnet mad mum and dad 😊👍🎄
Pulling the lever, adjusting the controls,the whole operation takes a while and looks like priming an engine. It’s quite a ceremony. “Is that all it does?” quips "M" sarcastically to Bond
Nice massager, Vince :) I have a similar product but it is built into a big armchair. It feels good when I get home from work, to get that relaxing massage, every day. Anyway, that big mosfet is a dual channel power mosfet, it is needed in order to change the motor polarity if needed, for another setting. And, of course, to save space by putting 2 mosfets in one package.
Great fix vince,and just in time,I think your fault finding is great,perhaps after Xmas you can show us all the fixes you had to wait for parts and bodged it together just to show it working,well done on the series though mate
That 4 conductor set of wires make up an I2c interface Gnd / 5V/ Data /Clock A oscilloscope on the data or clock would confirm communication on the bus
I've also seen strange things like this where it starts working after I probed it with my meter or installed a different power supply. I think those mosfets or atransistors get stuck somehow.... kinda like a relay. Maybe it is a microscopic short that eventually gets burnned away but I'm leaning towards the components getting stuck internally somehow. Also.... You need a laptop.... a laptop could help a lot with translating stuff...
I am amazed by your patience... I'd be jettisoning that thing in the garbage if it was for me, I can't stand micro SMD electronics. Yet I ejoyed your repair and that thing isn't going to recycle before has done its job, which it will... not for very long I guess, way too much plastic in the gears. I am amazed they don't get instant returns for broken plastic bearings.
Vince if you screenshot the part of the document you need to translate put the image through google lens. It’s far from perfect but it’s better than nothing.
„It looks brand new, so there can’t be too much wrong with it“ - I’m still watching, but it’s the longest video in the series, so I don’t know if I share your optimism. 😄
Unbelievable language restraint. If I had something randomly starting and stopping working like that at 3am it'd be learning some new words! As per other comments, the mosfets look like they're designed to run the motor in both directions so your temporary fix will become a short if changes direction.
Excellent Smithers! You got there in the end. I do feel sorry that you are having to be up at all hours of the morning to get these videos done. I know you said "If only I had checked the mosfets first..." and probably commenters may say the same, but unless you had done one of these items previously then for anyone doing the repair it is a pure random lottery as to what you check when. I wonder if this was left for ages unused from new, motor stuck itself up, and the power spike needed to free it blew one of those dual mosfets? Guess we'll never know. Maybe mosfet simply failed at manufacture. Keep up the good work and please get some sleep!
Well done. The wonders of capacitive touch, any fingers, metal, probes, breath etc may cause random effects. Original fault may have included processor not resetting properly. Possibly, a noisy PSU (maybe worth scoping / looking for a voltage drop)
Hi Vince, Was this "The spark of life"? Apparently not 😀 Some of the fixes you manage to achieve remind me of the proverb - Even a blind chicken finds a piece of corn 😀I admire your persistence! P.S.> When do you sleep?
I am a day late but yes finally a long one! This ones gonna be good and i am sad that the series is near ending. 10:40 yes thats the RF receiver that receives the rf signals of the remote. Its recognisable because they always have a crystal on them for the timing and tuning of the rf band. 15:00 Those springs are for the capacitive touch buttons. There is a small chip that basically will put a small voltage onto them and if a human finger comes by and touches it, that voltage value will change and the touch chip detects a button press and comminucates via i2c to the Fmd (Fremont microdevices) mcu on the other board. Also those dual mosfet packages are used to create an H-bridge for the motor to allow the motor to go forward or backwards. I have a neckmassager that also has an H-bridge and reverses the motors after X time.
Granted I am commenting 1 minute after posting, but I want to show you my appreciation for these advent fixes. Love all this. Thank you Vince!
Thank you so much!
Love the logical processes you go through. Excellent series, thank you!
Thank you Vince, i must say i have truly enjoyed having a fix a day from you.
You're a legend Vince. How you manage to fix these things time after time, with no formal training, is amazing.
You're amazing Vince. I used to repair large system computers for IBM and I miss troubleshooting stuff. Your videos bring it all back.
This is the kind of fix that makes our brains understand the logic and routing of the circuit; I am getting smarter with each fix.

😂😂 I would like to maybe do a week a month, going forward 👍
Hmm.. two p and n channel Mosfets.. so most likely they make a h-bridge. I wonder if the motor would change directions after some time. With your bodge wire that would create a nice short.
Yes, that would pop the other MOSFET too.
Exactly. Those double MOSFETs are half bridge, so they create H bridge, so the motor can spin both directions, for I assume more interesting massage.
Well done Vince on another epic release, was worried that you might not make it today. Great series. Thanks for all the videos. Getting me through a tough time at the moment.

Love all your videos Vince! please keep em coming they are very relaxing to me ❤❤❤
Have really enjoyed this series. Thanks Vince. Merry Christmas.
Merry Christmas to you too!!!!
Hi Vince...trying to fix this with NO schematics, and watching you troubleshooting this was very impressive... this was a great fix.⭐⭐⭐⭐⭐

A bit of proper faulting. A real epic!

In the UK he still had 1,5 hour, but from my perspective just half an hour. Glad you made it Vince, enjoying every video! Thanks! 🙏🏻
I think this thing is for the part of your legs between your knees and your feet 🙂
Thanks for another epic fix and this time with 2x sparks 😎
Another banger (literally) of a video. I bet you can't wait for xmas to be over... 🎅
The legs on that FET looked burnt, actually, right next to the housing. Anyway, good job again, Vince.

the Tower of Resistance! Those 2x2 MOSFETs are forming an H-Bridge for controlling the motor.
Still got nits…

Looks like the massager is newer than the power supply as it still has the "CE" mark, The massager carries the "UKCA" mark.

These springs are capacitive sensors so they probably go directly to a capacitive sensor IC or a MCU with capacitive touch sensor pins.
Made me laugh this one, explosions and tickles....😅

“Hello there my mate Vince here, and today we’re going to be repairing a rocket ship to fly and steal the moon”
Once the advent fixes are over, you should take a much deserved vacation, Vince! 😊
It's his only income, so might not be possible 🙂
In my experience from fixing interior heating fan motor issues on vintage cars, it always are blown mosfets
„It looks brand new, so there can’t be too much wrong with it“ - I’m still watching, but it’s the longest video in the series, so I don’t know if I share your optimism. 😄

remote is probably radio / rf, as receiver has a crystal, and remote no infra red led.
Unbelievable language restraint. If I had something randomly starting and stopping working like that at 3am it'd be learning some new words! As per other comments, the mosfets look like they're designed to run the motor in both directions so your temporary fix will become a short if changes direction.
As it has a PAT test sticker on it is NOT a new item, it's used. New items don;t need to be pat tested so that is definitely not new.
The springs aren't very responsive in recognizing your touch, because they are capacitive, and you have the board 'flapping in the breeze.'
Excellent Smithers! You got there in the end. I do feel sorry that you are having to be up at all hours of the morning to get these videos done.

Hi Vince, love watching your videos, but how do you find all the faulty products? Do you have a specific search query for it?
U zapped it by accident haha now it works
Great video, You deserve relax time ! Think they use those mosfet for doing reverse rolling different mode … Happy Holidays ❤️🎉
i love how you state what time it is and you get text or email. got love it
4:21 Vince, you ever considered getting yourself a power driver for things like this? That's a lot of screws!
Well done. The wonders of capacitive touch, any fingers, metal, probes, breath etc may cause random effects. Original fault may have included processor not resetting properly. Possibly, a noisy PSU (maybe worth scoping / looking for a voltage drop)

10:40 yes thats the RF receiver that receives the rf signals of the remote. Its recognisable because they always have a crystal on them for the timing and tuning of the rf band.
15:00 Those springs are for the capacitive touch buttons. There is a small chip that basically will put a small voltage onto them and if a human finger comes by and touches it, that voltage value will change and the touch chip detects a button press and comminucates via i2c to the Fmd (Fremont microdevices) mcu on the other board.
