Dear Jonny congratulations for your skills in troubleshooting every electronic equipment. Please, continue to share your experience with us! As already said I am very glad to follow your fixing adventures. I am sure that I am not the only one...Cheers from Italy.
I have Philips AT890 for about 5 years now and face the similar problem like you, so I follow this video to fix the switch, this is very helpful for me, thanks a lot!! 👌🏼
I've a different Aquatouch model that's about 6 years old, never used it 'wet' but I still suffered an intermittent switching problem though. Anyway, I pulled it completely apart following your instructions, then gave everything a damn good clean with various brushes and some ancient Remington "Shaver Saver" cleaning/lubricating liquid. After reassembly the machine works perfectly, looks as good as new and smells great. I just hope the battery's OK still. Oh, and I will NEVER use it 'wet'. Many thanks for the video; it gave me the confidence to pull my shaver apart.
That's great to hear. Well done! You may have to recharge it a bit more frequently than a new one but that's fine.
I had same problem with my Philips Aquatouch Shaver AT620/14. I am able to fix it after watching this video. Great salute to you sir for your technical help! Hats off to you!!
You're welcome, thanks for watching!
This guy is mad committed to a pound of effort to save an ounce of waste. My hat off to you Sir, indeed!
Thank you. If someone learns something it was effort well spent. Still shaving my face 3 yrs later, could do with a new battery tho :)
❤❤@@JonnyFix
Bro, this is the exact solution for my philips sensotouch 2d. My razor wouldn't start, or start for a few seconds then turn off, while all the lights flash. So i just cleaned the start button like u did. But i chose not to unsolder it, i just removed to top cap of the button and cleaned the 2 plates and the bottom contact. Thanks a million!
Just opened mine. Same thing will hopefully fix it as well!
Nice job, i'm waiting impatiently for the next video.
Used this to access the sealed area of my AT830.
Even after 2 weeks of non-use there was moisture in there. I dried up all of the moisture and it works like a charm again.
Good stuff. I've cut back to washing it out every now and then, rather than after every shave.
This was just what I needed to repair my Norelco. With close to 100,000 views, It seems that this is a very common problem with this product. Hopefully Norelco will take notice and improve the switch! Thank you Jonny, you saved me the cost of a new one!
Thanks! Good to hear, well done.
In fact only 1% of the users of this product take pains for even thinking and then attempting to repair the trimmer by themselves, leaving no option except to throw and buy afresh. The company takes advantage of this mentality of the helpless customers. Moreover, rest the faulty switch, the product is robust and so will fail seldom. The company, may be, intentionally leaves a weak point in the product to maintain sales figure up. Replacing of the switch must be difficult as that may not be available in the market.
Nevertheless the effort in attempting to repair the miniature giant weak point, making a nice vdo and the commentary definitely deserve applause.
WELL DONE.
Very useful video, thanks for sharing. For anybody else that thinks their on/off switch may be the source of their problems, it's worth noting that it is possible to dismantle the switch while it is still mounted on the circuit board. I managed to very carefully prise the metal cap off my own switch, clean the intervals, and reassemble it. 👍
Good idea. Less chance of losing bits if it's attached to something larger.
@@JonnyFix Thanks very much for the great video! I was also able to directly pry out the metal cap without soldering (not that I have the equipment) and finish the cleaning, and then realized someone in the comment section also did the same!
@@youl1840 Awesome, well done!
I have a different model, but this was exactly what I was searching for to replace the shaver head holder.
Thanks, really brilliant. Anyone who has done electronic repairs will be impressed - even taking apart a micro switch and repairing it!
Oh thank you very much. I really appreciate that!
Thanks good video. I think I will try warming up plastic clips with a hair dryer before replacing them.
Excellent photography gear!
I was looking for a 'how to open' video when I found your video and my shaver had the same problem. No shave 2018 is going strong, but I'm glad I could get this fixed at least!
Awesome! I'm not brave enough to grow a beard
Same here! Not sure if I am going to attempt the repair though.
Many thanks for this video. I fixed my shaver with same problem. Greetings from Italy
Good to hear, well done!
Just repaired mine following this video - a switch fault I think. I didn't go as deep as you though, stripped to the board and then a squirt of contact cleaner - 10 seconds later and it's as good as new.
Thanks so much!
Good job!
Thank you Jonny! This was really nice :)
Cheers bro. I've been trying to figure out my shaver model number for hours, when suddenly i found your video and luckily your shaver is exactly the same model as mine. And sure enough you tell the model number right at the start of the video. Instant problem solved cheers. The problem i had was the model number has faded off the back of the shaver and is no longer readable. And i need to order replacement blades for it. Was a bit of a nightmare without knowing the model number lol. Thanks heaps you saved a lot of headaches.
Good stuff!
Thanks Jonny Fix. Very helpful video. Instead of pulling the miniature switch apart, I dribbled some DeOxit cleaner ($30 at JayCar Electronics) into it and operated the switch multiple times. After that it worked much better. After reassembling the shaver, I shook it (thumped it) vigorously from side to side to slosh the cleaning fluid and corrosion products around inside. After that it worked perfectly. Thanks so much Jonny Fix.
I watched this video late last night and this morning had to strip down my Philips Sensortouch as it suddenly stopped working. Tried charging it first but all charging lights were flashing very erratically. It turned out one end of the battery had disconnected itself , the tab weld on the end of the battery had given out. Soldered the tab back on the battery and now working again.
Strange thing to happen. Maybe dropped a couple times? Well done tho!
Wow that was tidious but interesting!!! Now I know what those little look like, inside and out! LOL Thanks
Going to try tomorrow 👍👍👍
Good morning, I have a Norelco S1560 waterproof model that I dropped on the floor recently. Shaver was working fine until I dropped it. It worked for a couple seconds but now it will not work at all. Wish I could repair it but electronic boards are too sophisticated for me.
Great. @JonnyFixy you can purchase titanium forceps that are non-magnetic.
Mine is PT720, exact same problem. I will buy a new switch to replace it. Thanks you!
Glad I could help
I bought 10 switches from Aliexress for $1.3, replacement was easy. Now the shaver works as new.
hey man, thanks a lot. I had the exact same problem with the same model and solved it. Thanks again. ash
Down with whiskers!
@@JonnyFix please where can i buy the battery because i dont know which one i should buy thank you
well done fella
it was indeed painful to watch but i couldn't leave the show hee hee
wow cannot believe I have a very similar issue. shaver stopped working and turns out on/off switch was faulty. thank you very much for the video.
I had mine since 2015. My I'm not willing yet to throw it away although I bought another one for now.
thank you!
You're welcome :)
Thanks for the video!
What kind of battery in this device?
Excellent video. Thank you. This helps me know how to open my philips aquatouch AT750 without making mistakes. My AT750 only has five uses. The battery runs for only one minute. The problem is in the battery ??? Or somewhere else? Thank you very much, greetings from Argentina
If it doesn't turn on until after you plug in charger than probably the battery but without checking the voltage while it's running and seeing if it drops off quickly it's a bit hard to know.

Thank you sir, I appreciate you took the time to comment!
@@JonnyFixAfter looking the VDO so many times, I gathered the details of the fine work on the micro switch. Mine Philips AquaTouch shaver is suffering with the same defect with its switch. I find myself somewhat confident to take up the surgical strike on it. I guess, desoldering the switch from the board may not be necessary to open it. If the top silver cover can be detached from its base, it can be cleaned well. It will avoid the risky task of desoldering and soldering again. Do you agree? By the way, there are two contacts on either side of the switch on my circuit board from it. I want to wait for your experienced advice and nod before going ahead.
@@madhusudangupta3661 yes I'm sure the switch can be disassembled without removing it from the board. In hindsight I should have done this 😊
Mine was purchased in April of 2018 and as soon as the blade replacement light came on, the switch started acting up. After
somewhere between 10 to 40 switch pushes it would come on or after unplugging it from the charger it would come on. What I ended up doing is holding down the switch to get the blade replacement light to come back on and then holding it to power it off. Then it started working again.
Wow, I bet it doesn't say anything about that in the user guide!
Definitely, this line of shavers is water resistant, but not water proof. I had an AT940 that I used over two and a half years, and this week it stopped working! When opening the shaver the PCB was all wet, even with the sealed protection. Since the PCB had broken trails, I sent it to the trash! I'm disappointed with Philips, now I expect to find a new replacement for my AT940.
Very interesting little repair :^)
I just ordered replacement capacitors for my philshave because some clown( who wil remain nameless) dropped it into a basin of water.
Then tried charging it before it was fully dried out :^0
What screw bit is used to open the back area to replace the battery
Hi Jonny, I have a problem with essentially the same model of shaver. The battery works fine, everything works as it should except the motor is not turning the mechanisms past a point. It will turn it say a quarter of a turn then just stop, but will still make the buzzing noise as it is still working. It's as if there is something jamming it in the motor area, as I have disassembled the rest of the shaver, cleaned it and still no solution.
Without looking into it I'd guess the drive gears have stripped where the motor meets the 3 spindles. Another possibility is the brushes in the motor have worn out.
Very helpful video Jonny Fix, tank you. I don't understand if the battery is NiMh or Lipo. 1,2 or 3.7 volts?
Honestly don't think I took any notice but given the charger is 8V out and we have 3V on the switch I'm going to guess LiIon 3.7.
Thank you very much for a cool video.
Maybe you could help me with my at750. The fact that I accidentally submitting to a razor input more than 15 volts, and the input resistors were burned. If they were marked, I would easily able to change them, but it's R106, R108 and R109 in base-emitter circuit.
Also I can not find the network scheme of this board. Could you please help me in determining the value of resistors?
Thanks again.
Just popped mine open for you, had to remove these from circuit to get accurate value. R106 is 100k. R108 is 4.8k. R109 is 470ohm.
thanks a mill sorted mine following your video cheers
Awesome :)
great patience . do not use with wet , dry is better .
Nice bideo. Congrats. Can you support with a suitable schematic for Philips at610/14, please.
¿Cual es la punta del desarmador que te sirvio?
Cheers mate, for this video. I was actually looking for how to bypass the "cant use while charging" safety feature, as I am not gonna use it in a bath tub or shower. However there was also this button issue for my Philips Aquatouch AT610 and this video was sort of an enlightening. I would still like to know whether there's a way to bypass the cut off while charging. Thanks again. :-)
With the battery life getting shorter now I would also like to know how to run it on charge to :) If I get desperate and find a way I'll make a video.
Jonny Fix Hi, Thanks a lot for your kind reply. Guess this is a research topic for both of us :-) Hope we could help each other. I will update you if I find a solution. Cheers.
perfect video!! Thank u so much!

Now that I have fixed the corroded switch in my Aquatouch shaver, I won't be using it wet any more. In any case, I think it does a better job with just a little lubricant and without shaving soap and water. This will also avoid the internal cavity filling up with a paste of decaying soap and hair. Yuk.
I had the same problem - the solution? Bought a new shaver. Can't really complain since the Norelco 810 lasted about 7 years. Actually I can complain. Norelco should upgrade that "switch" to something a bit more robust. It probably cost them $0.50USD. The upgrade? Maybe $1? So unless Philips Norelco picked that "switch" as a planned obsolescence, they might consider the "upgrade". Might give them a better reputation. Which might help there bottom line and survive-ability. In today's very competitive markets that's probably something to think about.
I didn’t use for few years and it didn’t charge when I plug in recently. There is no light on when I plug in. I took apart and checked the battery voltage is 1.0V . There is no any water damage. Do think I should change battery?
Charge it slowly, no more than 100mA, until it reaches 3.8V then it should be ok to charge normal to 4.2. It may have lost some capacity from sitting at that level.
any idea of the dimensions of the switch mine got broken need to replace the switch...
good video, I hope you can help me, I have a razor "philips norelco sensotouch 3D" more than a year ago that I do not use it and today I wanted to do it and did not light anything light, try to load it and also did not start anything. My question is, do you know what is wrong? I hope you help me thanks.
I believe this model has a lithium-ion battery. If not used for a year it would have gone into deep discharge and shut down for safety. You should replace it. Unless there is physical damage inside there is no other likely reason it doesn't work.
Have fixed switch but my current issue is with the DC motor assembly. A small accident and the two leads snapped requiring the end of the motor to be removed. All 4 metal lugs have broken and still cannot remove end to fix the wires. Have I missed something?
Sorry I've not had to disassemble the motor. I think they can be quite tight
Can we remove out the metal clip lock without remove the whole switch from board?
I just repaired one, it works well.
I would say you could with a sharp enough instrument
Hello. For a Philishave 8890, can you tell me the type and characteristics of each battery? and more, any place to find them? Thank you in advance.
I do not know, sorry.
Thank you for sharing your experience in repairs. I tried to fix the switch but to no avail. Do you know if it is available to order online? The reference on my board is S301. Any suggestion for a similar switch?
Try this, of course check the dimensions first, if it's not right you can use their filter to narrow it down. If you can't buy from them try digikey or mouser. nz.rs-online.com/web/p/tactile-switches/7856428/
@@JonnyFix, thank you! I guess I'll have to search a little bit.
I have the same problem, what do i have to do?
I achieved disassembly rq1250, i disconected the motor but the circuit shown the same lights .... the motor dont start, its want begin to start but not, and when i disconect this from the panel the panel shown the same lights
Does the motor spin if you connect it to a different power source? If it doesn't when set at the normal battery voltage then you need new motor. Prove this by checking voltage at motor terminals on pcb when switched on.
weree i would get new battery for it
I want to take this opportunity to ask for some advice for the repair of a Raspberry clone card, I see from the video that has technology suitable for any electronic job. But in this case the TP (test point) are really tiny and not easily visible without a lens of at least 30X. In short, it does not come on anymore and I do not need it if it does not work again ... SY8008 problem. Thanks so much.
You need to identify the main power rails and make sure they are present. I would then use a scope to make sure the clock signal is present followed by activity on the flash memory data lines. No clock may be bad cpu or bad solder joints to cpu. Some data traffic probably means corrupt OS / boot loader or whatever it uses and will need to be re-flashed. It could mean bad flash memeory. Just initial thoughts. Have never worked with one.
Unfortunately I do not have an oscilloscope available. I can not access the pins of the CPU, here you need a hot air station to detach it and then you need a kit (cheap but functional) for re-balling. But if I connect the tp "Vbus" with the tp1 can I feed the card directly from the micro-usb ...? It is an attempt I would like to do! I've never been lucky enough to see one of these cards running. I remember that when I bought it and fed it I immediately saw a grayish smoke and the IC SY8008 was carbonized instantly. I have the spare part but I miss a suitable lens otherwise I only struggle with the sight without results
That chip should only have input of 6V max. I would caution against jamming 5V onto TP1 unless you know for sure it should be 5V.
How to remove and fix the one touch shaver open button
IF IT HAS LITHIUM BATTERY I REMOVED THE PCB AND HARD WIRED IT TO A USB CORD. PLUG THE USB INTO ANY USB PORT AND IT WORKS FINE
i never shave but good job
thumbs up buddy, I don't shave either, but you really need one of these anyway.
PLEASE tell me what voltage the charger is?! Your great video tells me which is negative, but I can't find anything that'll tell me that quite important piece of information. Thanks
They are 8 volts
@@JonnyFix Hey thanks for that. I do wish that Philips would stick to a voltage for these, I've found 4.3, 15, and now 8 !!! All for 1 battery that may be 2 cells. The unit also shows " 15v = (DC sign)/54W ", so 15v in ! Again, for 2 cells....it doesn't make sense. But that's Philips for you.
OK, FYI I've just seen in VERY small print that mine (PT920) takes an HQ8505 which is 15v. Thanks for answering... I asked the question when I had been squinting at the thing without my glasses on !!! Have a better day!
Now to fix the "no charging" problem!
@@martinbolt8007 mine was also very small print. I wonder if the higher voltage units can be used while charging. Mine only puts out 100mA and usage is disabled when charging.
Maybe a shot of isopropyl will do the job
Can you inform me on how to put the wheels and cutters and sprockets back together?
Here's what happened: I opened the hinge to brush/clean out the shaver and it all fell apart suddenly and unexpectedly!
Don't know how the parts go back together, but would like to keep this shaver as its been a good one and is working fine, apart from the
mess I've just described. Would appreciate your advice and possible a short video. Please
Cheers
Here's the user manual. Start at page 11 www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?slg=en&scy=nl&ctn=AT750/16
Big help. Thanks...I think the locking nut...the plastic, black sorta circular item with the arrows imprinted on it, may be the culprit. I've cleaned it all out and re assembled, but I feel the locking nut isn't holding as tight as it should. Wear, I suppose. Thanks again. Here's to smooth chins.
In the centre of the black locking wheel are 3 flats that rotate to move under 3 overhangs on the blue stem to hold it in place. The whole assembly needs to be sitting down in position right to allow this. I can't imagine they'd really wear out so unless maybe one or more of the 3 flats has broken off. I used to wash mine out each time but the damp made it start to smell bad so I just shake/tap it out and give it a good clean every now and then. Is all good :)
Hi....I'll take a look at that and thanks again.
:)
same happened to my dad and thanks to this question I just fixed it 😊 so thanks ✌
please where can i buy this battery because ihave the same one please write me the links of buying thank you
I wish I knew, then I could get one for mine. It seems to be special to shavers only.
2V/Div x 2 divisions = 4V not 3 which is expected for nearly fully charged Li-Ion.
Correct. It was more a point that it was a lithium cell and I was just throwing numbers around. Most cells stamped 3.7 will be full at 4.2.
Any clue? the battery voltage holds good and the shaver runs if connected directly but if switched on by power on button, it won't turn on. Only yellow battery LED blinks! Model Aqua Touch s5050
From off try holding power button down for a few seconds until light stops blinking
Many thanks for immediate reply. I tried more then 3 times from off pressing power button until yellow blinking stops. But in vain.
I doubt some Battery voltage sense to the chip is not working. Any schematic/circuit diagram available?
@@PrasadKakara I don't know where you will get one. You will need to find datasheets for the chip and work out what is wrong. Check the transistor that drives the motor
Jonny Fix I will do so and post if i can figure out the root cause. Thanks for the support.
My light is solid orange on my shaver how to fix Phillips water Proof it whont turn on
I guess it depends on model. It might mean the shaving head needs to be replaced. If not, you will need to open and trouble shoot.
Hi jonny..i just replaced the battery to the shaver..and now the beard trimmer and shave are running simultaneously without shutting off. What do you think is going on ? Worked fine before the battery gave out.
Double check your work, make sure you haven't blobbed solder across connections that shouldn't be joined? Otherwise I don't know. Is there a switch to turn trimmer on and off or is it only active if you pop it out? (don't know this model). If it turns on when popped out maybe something isn't aligned correctly when you re-assembled.
@@JonnyFix thanks for getting back to me.all i did was replace the battery..once i soldered, the unit went on ..trimmer and shaver together! I tried to push the switch off..but it wasnt doing anything. So i had to disconect the battery. It worked perfectly before the battery gave out...🤔🤔

@@mr.disney4740 Battery in backward?
@@JonnyFix that's a great call....could be ? well i had it in the other way..and it wouldn't go on...i am baffled by this😔 (HELP)
@@mr.disney4740 well if you had it the right way first and it didn't work then the old battery probably wasn't the problem. If I had to guess, putting it reverse fed the motor via the mosfet driver body diodes. I think you still need to find the original fault.
What is the Torx size to get the screws out???

Possibly a dirty switch like this.
@@JonnyFix and how can i fix it sinds i got nothing to unsold and resold?

Hi, any chances you could post the battery number? I am trying to order a replacement battery for mine and the number you're reading out in the video doesn't get any hits for me on Google.
Sorry that is the right number, I was also unable to find it. Seems to be specific to this device only.
@@JonnyFix hi. I have the exact same shaver. how would one know which battery to order as a replacement?

Telling me battery model
Battery model is printed on battery. I do not know where to obtain them.
Cool yes did does micro switches ,,, as said not interesting but nice to do
Great video. But I’d just get a new one for $30. 😂
These Philips shavers are the biggest pile of crap Philishave have ever produced. I have an AT928 and it is supposed to be waterproof - yet when it stopped working, and I pulled it apart, it contained a heap of water, right through to the PCB!
The plastic lugs on the cover over the PCB, snap off the instant you try to pry them off, making the shaver non-repairable.
I went to the trouble of buying a new battery for it (it crapped out after only 18 months), and when I went to start it up after battery replacement, it won't shut off!!
It's not worth spending any effort on repairing this model Philishave, they are truly a throwaway model!
Heartstopper at 29:13
Я хуею: чтобы отремонтить кнопку, надо доставать осцилл ;)
Bought it on sale at Walmart, never used a wet shave and dead after 6 months, piece of junk threw it out.
At the end you skipped the part that I clicked on the video for 😢
My apologies
What a shitty shaver. I have it and it hasn't been working properly since I bought it new. I got to where I checked the current between two points on that circuit board and that fixed it, it started working, or at least it turns on - for now. I don't get it. Still doesn't seem to buzz at full speed though.
I have rebuilt the switch another 3 times now, not the greatest quality. I guess you could start by testing the motor with a bench supply. Put battery voltage on it and see if it runs fast to prove motor is ok. If so the battery could be failing or the transistor that passes current to the motor.
I think over a year, about the same frequency of use.
Cioè, io a te non ti farei smontare neanche il cavalluccio di mio figlio, azz! sei proprio negato!
Plp
An osciloscope to repair a shaver ? XD can I use the ISS engine to repair my lawn mower ? XD

my god you waffle on
Glad you enjoyed!
Repaired ok,but very dirty inside!
not well structured. you need to say first what you are looking for, what specs are to be found, then what you find, then how you fix it and then show it. this is 38 minutes too long at the moment without a clearcut strategy explained.
