Philips Series 7000 SHAVER - WEAK - Can I Fix it?

Visit PCBWay! Your PCBs, 3D & CNC One-Stop Solution: www.pcbway.com
In this video I attempt to fix a Philips Shaver that was given to me by my friend. The battery has already been changed and it is very weak. What could cause that? Faulty battery again? Installed incorrectly? Let's find out
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in these videos.
Many thanks, Vince.

[@DaveDoc1984]

You are spoiling us :) another video in relatively quick succession. Keep them coming Vince :)

[@Cha-chingWV]

An hour is not long Vince. Prime time TV shows are an hour and I'd rather watch you than mainstream tv,

[@grayhalf1854]

And at double speed it's only 30 minutes! 😀

[@ncc1701deee]

Exactly.

[@dlewis9760]

"What's Prime Time TV?". I walked away for TV in the US in 2020. One those rare occasions I see what I'm missing, I see I'm not missing much.

[@timsowry2237]

Totally agree

[@ElevatorWasher5000]

I watched this video during dinner so it’s fine

[@Jack-nb1zx]

I honestly enjoy your long form videos. Can’t stand KZbin shorts.

[@senketsu8632]

You never need to apologize for video length, Your videos are amazing as well informative , They give me inspiration to keep trying to fix what normally id just toss out. Love the video and your amazing VInce.

[@badeadrian]

Google: 18650 battery holder with leads.. you can buy different types..1,2,3,4 cells... you don't have to solder the battery... I used to do that kind of butchering with batteries...at least you could use your spot welder to attach some plates to the battery... after the soldering... Great job 👍.. Greetings from Dartford!

[@allenrussell6135]

I appreciate the longer videos. Keep them coming please. I always learn something from your videos.

[@LAZERBLADE194]

Great video Vince! Yes, it was a long one but it was a good fix! You've chatted before about wanting good fixes for your videos, not just opening something up and finding the ground wire has popped off the battery terminal for example and in my opinion this was one of those good ones instead! I think a lot of us don't mind the long videos. I'm sure they're more of a pain to edit down though ahaha

[@VicknairDoesThings]

I think that thing (30:40) may be a ferrite bead “choke” for removing high frequency noise from the motor getting back to the board. My theory is it came off when you desoldered the motor to power it with the bench power supply.

[@I_Evo]

Only 15 minutes runtime? I've got a Philips Series 3000 shaver and I'd estimate I get about an hours use for a full charge.

[@SimonNemeth]

That old chip was hitting 122C. I'm surprised it even stayed intact. A bit of advice, you should probably check the actual temperatures that your IR cam shows in future. I'm sure it would have saved you some time in this case. You know yourself that there's no way in hell a healthy chip of any kind in a small device like this would get so hot.

[@paultasker7788]

Thought I saw 120 degrees on there. It would be dangerous for that to be general use. 50 to 60 is pretty normal, case will usually warm up a bit but 120 is not right.

[@lowerclassbrats77]

If you need an electric razor, buy a Philips One Blade. It's $40.00 usd and cuts better, faster, closer, and with less irritation than a $300.00 usd electric razor. The replacement blades are also far cheaper.

[@colinrowe1853]

Never apologise for a long video i found it extremely interesting so thankyou

[@digihorse6730]

This is just an odd thought, but is that the right battery? The reason I say this is because the battery looked like it had the little extra internal BMS board in the positive end. Wouldn’t that be done by the shaver PCB itself self? ??? Was the wrong replace t battery fitted originally?

[@markshellard5894]

Another great video love it

[@fluffyblue4006]

I bought my Philips shaver somewhere in the 90's. Still going strong, no motor problems but the NiMH cells were replaced a few times during its life. Many devices with a Li-ion battery in it need to be kickstarted after the battery was disconnected, by connecting the charger momentarily. In your diag process, you did not plug the charger after connecting the bench supply as a battery replacement. Also, when it ran, you did not check the battery voltage while running. That would give a good indication of the state of the battery. The motor was blocking when it was turned against its normal direction. That is indeed a red flag. It also ran a bit irregularly at some point in the video. Also a red flag. So the charger IC was obviously faulty. When you first used the FLIR, the coil did not get hot, just the chip. That buck regulator was not 'bucking' to 4.2V anymore. I think, this chip died a long time ago, basically changing into a PTC resistor. When it gets hot, its resistance goes up. On this way, it will take a very long time for the battery to charge. And it probably won't stop at 4.20V. Owner probably kept it on charge 24/7, to ensure that the battery won't go down. But during 24 hours, the battery gets overcharged. Its lifetime diminishes quickly. And the motor might also suffer more wear with a higher voltage. This motor was too far gone, though.

[@patrick-c9j9t]

your videos are so enjoyable, i dont mind whether its long or short. I missed your signature triumphant 'Yyyyeeeeesssss'' jig this time around though. i quite look forward for that. 😄😄

[@brad9529]

Very good video, please leave them as long as you like. Ignore negative comments and do things your way. Your way is what most people appreciate.

[@hellhound-si5oz]

That's the problem with brushed motors, they wear out. Brushless better, but they have their own set of problems.

[@EpRoos]

You know what would be nice Vince, a short summary of the costs and amount of labor at the end so we have an idea how much effort you put into.

[@mitchd949]

I watch at 1.5x speed so it's like hearing Vince after a couple strong cups of coffee (or tea), so an hour goes by in 40 mins. I wonder, if I ever met Vince in person, would I think he's worn out or tired because he would seem to be talking too slowly?

[@aldo9923]

I watch at 2x speed

[@Mymatevince]

Hahahaha, I do the same thing when watching my vids back, for me 1.75x is the perfect speed. I also 1.75x so many other creators that they begin to sound normal and their normal speed voice is sooooo sloooowwww😂

[@red2]

2.2 speed gang here and sometimes 2.5x.

[@Landrew0]

Don't let the safety trolls get the best of you mate.

[@Robert-jf5oi]

Thanks for your hard effort, but generally, in particular electrical goods, you get what you pay for, and even if that razor wasn't faulty in the first place, that particular make and model is rubbish anyway. (I prefer Braun) Although when I used to service televisions, Philips, which was also affiliated with Pye, wasn't too bad ,at that time

[@Drew-Dastardly]

Oh yes, one thing for a service engineer - the official Philips service manuals were a thing of beauty and a joy forever. Up there with Sony service manuals.

[@Robert-jf5oi]

@@Drew-Dastardly Oh yes definitely

[@micbanand]

You do the work needed. Thanks!!!

[@hugosimoes5119]

Philips makes great products but I can not understand why they put a battery that takes 8 HOURS to charge and only provides less than 1 HOUR of total usage... I could unscrew it and see if I could replace the battery with bigger capacity. I unscrewd one screw at the back of the shaver but I gave up before mess with it. It has less than 3 months.

[@rebeccagarnett4166]

The timing of this upload cannot be anymore perfect Vince. Only a couple of hours ago, I was looking into Philips series shavers to repair. I've watched you for years and you've expanded my own knowledge and passion for 'tinkering'. I love your in-depth content. Your failures are always a learning curve and your exploration to understand is invaluable and something which I can relate to. Delivery is always spot on, educational and entertaining. Thank you for your work and thank you for the internet to allow me to connect with you. Cheers Vince. If you're ever in Yorkshire, let me know. A meal and drinks for you and the family. X

[@patrickcraenen5163]

If the polarity of the battery was wrong, the device would not do anything or release the magic smoke. Soldering 18650 lithium-ion batteries is very dangerous and can cause the battery to catch fire and explode. You need a battery with spot welded solder tabs!

[@Drew-Dastardly]

A bit disappointed Vince didn't demonstrate how effective the shaver was at the end. He certainly had enough stubble to demonstrate! 😉

[@Robert-jf5oi]

@Drew-Dastardly He did state he doesn't like to use other people's razors, though, and i don't blame him,but what a pity- Eh? 😃

[@Drew-Dastardly]

@@Robert-jf5oi I normally use bladed razors - I have to admit to using my dads or my brothers occasionally back in the day with no issue. However the one and only time I used a girlfriends BIC after a long stay over was the bloody ruin of my face. Never use GF/Wife's leg razors!

[@beavis6363]

Good video. Like you said, the story has to be told. It would sort of be a cop out to omit steps, and depreciate the learning value. Personally I really enjoy the long ones. Nice complete repair. The battery attachment had to be corrected anyways, and that chip had seen a bit of thermal torture. Add the new motor, and shoot, it's reconditioned. Super cool.

[@andrewstones2921]

I bought one of these in 2007 (similar Philips not the exact model) and used it for about 3 years and lost it. I found it in 2016 so it had been lost for 5 years, I obviously assumed that battery would be dead and expected it to be ruined, I pushed the button and it worked just fine.. I used it for another 5 years and then treated myself to a new 9000 series. I got the old 2007 one out the other day and it still works fine and holds enough charge to be useful. Compared to some other razors the Philips do sound slower, but they work well

[@CTCTraining1]

Well done Vince - your persistence is again rewarded, and a very enjoyable video. I could consider it a ‘Tea-break fix’ … plenty of time to cultivate, pick, dry, and brew the tea 😀 Keep up the great work 😀👍

[@mrjsv4935]

Nice fault finding and fix, liked a lot of that assembly section 80's style music too :) My shaver is Philips too, but corded version, model number PT710/17. Bought it in 2012 and it still works, altough new blades certainly would improve the result. Original cable from power supply to the shaver started breaking down, namely the top cover, the actual wires were still ok, but Philips haircutter (HC3400) I happen to have, use the same psu (HQ8505), so started using that one. The old psu still worked fine though, but because of that broken cable cover, it wasn't very nice to use.

[@home-space]

Why did philips change the design of their shavers so it won't work if plugged in and charging? My 20 year old one will work off mains when charging. Seems like a big downgrade or to get more people buying new ones when the battery dies.

[@jaredl2239]

Thank you for showing the whole process. I think it is important you show the journey to the fix/ failure and not set unrealistic expectations for viewers who may be new to troubleshooting and repair.

[@benedukt2223]

Hy Vince, there's no need for appollogies. I like these extra Long Videos a lot. Faultfinding is always a time consuming Activity.

[@Audit-The-Auditors-UK]

This device is made to charge a set capacity of battery and it cannot understand why the capacity of the cell is not at the correct level. The microcontroller is not happy with the lower capacity cell. You must put original type cell in it. The 18650 has to high capacity.

[@sirlordbabish3873]

Admittedly I wouldn't have started with the motor either but having experienced problems with brushes they're not as infallible as I always imagined. Like you say that device has been used a lot

[@home-space]

When I saw you reverse the polarity on the motor I yelled No don't do that. I have done something similar to a motor that is designed to only turn one way and killed it too. I think that is what killed it but it did also look quite worn. My Philips shaver is over 20 years old and still works fine and the one you repaired didn't look all that old, maybe 10 years.

[@marshall1157]

I have a phillips nerelco older model than that 1 with 2 AAA sized battery's in it. it lasted about a year then wont last more than maybe 45mins total use. i have a norelco even older with that battery in it and its still going strong 5 years later on same battery and motor.Lasting also about 45mins use.

[@gower1973]

What a piece of junk motor in that shaver, I bet its not cheap either, it should have a brushless one in it. All modern shavers these days seem to be junk my Braun one cant cut shit, yet my twenty year old one gives a better cut.

[@Mouseketier85]

I love a good long video. Sit down with a good bowl of cereal and get comfy. It’s nice to see an honest troubleshooting and repair.

[@Ukmartian1701]

Those types of blades have changed very little over many years , my dad and grandad both had mains versions and sharpened theirs I was told you can sharpen them as they were a expensive replacement, just remove them a little drop of 3 in 1 oil on a piece of flat glass and rub them in a circular motion ...

[@itsmicxgaming]

Something like this happened with an electric razer I bought. But I think this is becuase of a different problem (I am still typing this while watching): I accidently plugged a mains plug into the razer instead of using the USB to thingy connector as you're supposed to. Not sure how really to explain technically how it broke.

[@barryabell5410]

Stop apologising you do what you do to prove out faults whether its 1 or multiple keep doing you as it works and your video's are informative and helpful

[@thomasodonnell2191]

A long video is fine!! If anything we just pause and have something to look forward to later.

[@chef717717]

No applogy needed . I love the longer vids . The journey is important to be shown . Dont let any haters try put you down . Keep doing what you are . Helped me nk end . All best

[@wisher21uk]

Brilliant fix yes I agree the chip was the blame, it was going into shut down nice call Vince well done 😊

[@craigbourne4792]

could you please tell me what spot welder you have , and would you recommend it. thanks from craig.

[@JasonPurkiss]

Well done Vince good work, perhaps if bored video 2 would be to put the old battery and chip back in to see if you was right :)

[@tomasparrado873]

The motor might be one way as it has an integrated diode to suppress back emf? You'd normally strap it across the output at the board, but it's possible

[@1988Mauritz]

1hour of entertainment is good stop putting yourself down we love your videos because of your style of videos the edits the searching for both parts and faults!

[@fenceup07944931177]

Be careful when you remove the blades. You should always keep the blade and the grills together as pairs, as they bed in, to each other.

[@hadibq]

couldn't go through lots of comments to check, but with such motors, you can spot two vents that allow you to separate the brushes before pulling out the rear cover. there must be some kind of special tool that holds the cover with the brushes pushed out on the sides.

[@regmigrant]

long form rules! I was going to give you grief about not showing the battery connection so you could avoid getting grief about showing it but decided that the rolls royce gold tweezers made up for it

[@TheSkaldenmettrunk]

-- Spoiler Saver What a Battle with that little device. Crazy. But Vince showed it who's the master here.

[@AcornElectron]

Length of video and watchability both fine. Bit of a faff and not great for drawing conclusions but it seems to work now?

[@Landrew0]

You pulled it off with the hot air soldering, but you should have probably dammed the chip off with wall putty.

[@Anthony_The_Chicken_Licker]

Very nice video 👏🏻

[@johnHAMMOND-l3u]

i do enjoy long videos

[@rondickson1491]

Another awesome video. Learning is half the battle and sometimes it takes a little trial and error. Best wishes from Virginia.

[@No1BRC]

Vince, spotwelding on batteries is easier and safer if you go with with two automatic pulses with lower power than just one with high power.

[@rodcon66]

Watching the first spot weld reminds me of me. Thanks for the laugh and keep on trudging through.

[@shevshep]

I like the longer videos so long as the content is different throughout. Good to have MMV videos back!

[@Tim_3100]

I have a 3000 series shaver i replaced the blades on mine it alerted me when they wore out another led light came on with shape of the blades ii changed them out and the light went out within 30 seconds

[@andrasszabo7386]

I have the same shaver at home. I needed to connect the charger for a split second, even though I have connected a completely charged battery cell, after I removed the old battery.

[@r4dius]

Looks like philips batteries are made to die fast .. any of the philips stuff I rarely use more than once a month will get battery dead fast

hi vince enjoy your channel however i. dont like your. pcbway ads as i pay extra to yt. to not see ads

[@SarahJane148]

you should be able to run that razer of the mains while it charges ive had 2 of them in for repair i just took the battery out and returned it back as a mains razer

[@ingenfestbrems]

49:28 isn't this explained in the manual? Remember taking out the blades and cleaning them

[@jacksat2252]

The battery too weak and nuked due to soldering got too hot with the soldering iron .

15 minutes runtime? Hmm I'd estimate I get about an hours or more

[@PaulBakewell]

I can never understand with Philip shavers why you can buy a 3000 series shave for £50 and you can pay as much as £350 for 7000 series shaver, basically they’re all the same! Great video, thanks Vince.

[@home-space]

Different cutting heads. My old one with triple cutters in the head is a lot better than my new one with single cutter. Although it doesn't look like Philips do a triple cutter head anymore

[@JoshuaJonah]

This is why you want lithium batteries to be the same charge level when installed. It sees the 4.2 in the old one and stops charging the 18650. If you uninstalled the old battery and tried just the 18650 I bet it would have been fine.

[@bob-s-bit-s]

Is it the correct charger? Mine is only 5 volts

I had a Phillips rotary shaver years ago but couldn't get a decent shave out of it. I went over to Braun foil shavers in the end and now I have two, both nearly 30 years old now and still going strong.

[@paultasker7788]

I had one in the 90s that was good but newer Philips models haven't cut fine enough. I've got a Remington one designed for baldness with 5 heads. Works an absolute treat for general shaving

[@peterlarwood8331]

A clue that you glossed over was that strange bit of ceramic caught in the case where there was no switch, that was one of the carbon brushes. Good fix and keep up the good work.

[@cypeman8037]

It only cuts one way so why would the motor work in reverse?
