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 this 'Trying to FIX' series. Many thanks, Vince.
The thing with the wifi board (if you want to fix it). Those are very common ESP8266 modules. If you want to fix it, don't throw away the old board. Buy a new board and then transfer the spi flash chip to the new board (the chip with 8 pins in the blue board that you removed). You don't need anything else.
If you have thrown away the old board... well, you need to find a dump for the spi flash of that board.
Thanks Dogo, luckily I still have the old one👍👍👍👍
@@Mymatevince Get urself a new board and fix it! I'd love to see it :)
The Wifi on these Philips things is disappointing to say the least!
I have a similar device from them and while it is functional the Philips app on my smartphone now discovers other people's purifiers...
@@oldguy9051 That's because maybe other people didn't take the time to proper connect the device to the network, and the purifier stills in discovery mode so it can be configured.
Technically that is a feature, and a lot of devices with wifi connectivity has the same thing going on.
I was going to say the same thing
Please Vince, when messing around with live mains PSUs start at the cold side output, if you're getting 5v, 12v etc etc out of the PSU then its a pretty safe assumption the PSU is good and then you'll know you don't need to touch the hot side at all. Only ever get involved with mains as the final resort when absolutely necessary. Stay safe 🙂
From my experience switching PSU's with bad output caps can sometimes provide the correct output voltages as long as they're not under (heavy) load, but the voltage will drop when (heavy) load is applied. Just make sure to test the PSU with load (which makes it harder to diagnose as you need the actual load, which might be dead/shorted, or you need something that draws similar power)
@@olafdesneeuwman8983 Oh absolutely (it happened in this video), there will always be outliers and yeah, assuming PSU is good without load is not exactly ideal however this scenario will be quite rare, in the majority of cases if your PSU is outputting the correct voltages then its good. Plus with PSUs in general, its simply good practice to start at the cold side and work backwards from there, you should only be measuring live mains if the thing is totally dead and you're looking for the break in the circuit, if you have anything at all on the cold side then then leave the hot side alone (at least until you absolutely know the issue is on the hot side).
remember you mentioning your longer videos dont do so well.
so im here commenting on how great your videos are!
thank you vince for the many, MANY hours of great, quality entertainement.
keep them coming!
(love the RR spirit videos)
I like his longer videos....but my schedule don't.
👌👍👍👍👍
@@Mymatevince This is how I reply to my boss' texts lol
I enjoyed this so much that I'm going to buy the same Air purifier if they have them available in Australia
I've had some bad experiences with Philips (and their lack of support when something goes wrong) so I steer clear of that brand at all costs| Never the less, your videos are mesmerizing and the longer, the better IMO. You should do one of their junk toothbrushes some time, that would make a great video!
I agree that the longer videos are wonderful and I'm disappointed when they end, but I never really look at the time of the videos to pick the longer ones. I should do that.
Philips being a bad product? No idea, but here's the way I think. Companies spend untold amounts of money on advertising and then try to chisel a customer who has a complaint? That makes no sense. Word of mouth is insanely effective. Ship the customer a free part or a free unit and you've got a friend for life. What's $400 when advertising? Absolutely nothing. They could slow or stop advertising if they handled complaints like that.
In advertising you need two things; Visibility and a good reputation. That's all there is to life.
Vince please get a good set of “helping hands” clamps to hold circuit boards and things while you’re working on them, i scream at the TV every time you try to work on something and it’s flopping around all over the place 😂
@Mymatevince
That capacitor was reading in the nf range instead of uf. Absolutely shot.
Nice fix on an expensive, but ultimately cheap purifier. Well done.
Thank you. After the big fighting with two hidden bolts of my AC3055, finally I could reach the electrical board and replace the condensers you mentioned. Now everything works fine.
I felt your pain at the end. This will be so useful if someone else ever wants to fix one of these
PP does vary. Sometimes its a stream, sometimes a drizzle.
Apologies for my immaturity. 🤣 Well done again!
😂👌
Had to open up the top of my air purifier to clean out a spill. This video was a massive help! Thank you
I bought the next model up 6 weeks ago for 50% less but I live in Sweden. I can recommend them, the filter is a HEPA filter specifically for asthma suffers people allergic to cats and dogs but I not 100% convinced that it is fully effective against them. It also works against cooking smells.
How long until you notice the smell is gone from cooking ?
Always check the capacitors, what could have been happening when you unplugged the wifi card is it brought the resistance down allowing it to boot loop / work sometimes even with the bad capacitor but when it was plugged in it raised the resistance to high for it to even try to power on
So removing the wifi module decreased the load on the power supply.
It's a great video Vince. Never thought it would be so tricky just to fix a air purifier, would be nice if manufacturers provide all the schematic diagrams so that these are not thrown away by people.
Hi Vince, try to look up the datasheet for the wifi chip, it is possible it contains a basic/recommended schematic and there you can find the values of the missing components. Other than that good job!
Great Job Vince! I think the unit worked with the wifi unplugged because it might have been drawing less current, and the ripples on the power supply due to the faulty cap wouldn't have been so big. Great job as always. Got video uploading tomorrow you might find interesting.. repairing a RGB laser...
my thought as well, a dying psu can sometimes still supply enough to work but the wifi card would have been an extra load on a bad power circuit
Thanks Mick👍👍👍👍
You can buy 3rd party filters and many of them are as good as the official ones for nearly a quarter of the price. I have been buying 3rd party filters for my DP01 Dyson Air Purifier since the one that came with it was spent.
Thank you Jak👍👍👍
Great video, I jumped on it because I actually had the same issue 6 month ago and the warranty service said the part (power supply) is not in stock
and they gave me the money back and the broken purifier, took it apart and the issue was also with the capacitors, not sure if they where just bad quality or just not the right spec for the job, but now I have my money and a purifier for a few cents :)
I'll be honest, I'll watch this video later, but I just want to say (before I watch it) - I am in love with that thumbnail.
Saddest electronics
Watched it- loved it!
🤣
Great fix Vince well done, when you suspect capacitors use a hair dryer and warm them up and if fault’s disappear you know it’s them 😊
Thanks Gary👍👍👍👍
@@Mymatevince you’re very welcome Vince 😀
listening to ur intro music is like sitting under a Christmas tree opening presents😂...uplifting and exciting
You always know that you will have a blast
❤️
Great video like always & the Wifi board seem to be an : ESP8266
Very common module, available in many versions on aliexpress around 3$
Many thanks, I had the exact same problem and could fix it for €0,30 in parts.
It was a nightmare to (dis)assemble this thing, but it works again!
I really like the bronzing capabilities of the yellow mat during these dark days.
🤣
I always look forward to your videos. They really are great bedtime viewing.
The missus watches the filth I watch circuit boards.
Ahhh marriage
🤣👍
I love your long videos 😊 I always get a little disappointed when it's a Tea Break Fix 😉
The reason why a capacitor can have a bad ESR but still retain its capacitance is that the ESR value is related to the state of the metal strips within the capacitor, so you could get a small area where its messed up/trashed and as a result increases the resistance even though its in a single localized spot, but the rest of the capacitor is fine and therefore is capable of keeping its capacitance value, hence why you can't rely on the capacitance value to check if a capacitor is bad or not.
Just to add/ pay a bit of respect to the people I got this information from was the UA-camr Learn Electronic Repair who did a couple of videos on the ESR meter and how it works, and also a video by DiodeGoneWild on the ESR meter just for anyone who wanted to learn a bit more.
Next time you do the debugging a board with live voltage, would suggest trying to secure them firmly somehow.. bare minimum maybe insulated tape.. it is a bit nerve wracking watching you measure the board while it is live
Probably best wear some kind of protective glove too?
@@paultasker7788 gloves might reduce your dexterity and raise risk of shorting stuff with the probes though
Vince is using a ground isolating transformer, which significantly reduces the risk of shock (when observing best practices).
If it's nerve wracking to watch, don't watch
I think a world without Vince would really suck. Please be safe and think out and plan a bit ahead when working with high voltage equipment.
Liked the repair. Please keep making these.
Well done Vince.. I just fixed an Alexa enabled coffee maker with the same symptom.. and same fault.... I believe your fault was a smoothing cap for the 3.3volt support.. It likely went further out of tolerance with heat.... Mine was bulged a little , but same thing.. Great job !!
Great video mate. That gives me some idea on why my Phillips 2000i failing to turn on.
Hi Vince,
Great video! I have an idea for the new one: build the hotplate kit that Great Scott recently featured, find the values of the missing smd parts (viewers that have similar working units might help) and fix or rebuild the wifi board.
those caps never have enough charge to kill you , rather give you a lil shock , also most modern power supplys have bleeder resistors across those big capacitors (to discharge them)
I wouldn't risk it anyway, because some people have already died from such shocks due to undiscovered heart defects. And since the risk is avoidable, I'm also cautious. And I already had some new televisions that were still charged after 2 days, better be careful.
NO they do not most small appliances just use the cheapest Chinese PSU's
“We don’t need that wifi board”. Next second “I wonder if we can buy that board”
We have had the bigger and older model running virtually 24/7 on settings 1..2..and 3. It lets us know when the filter needs cleaning and reset is easy when we get a flashing reading. I paid just over £200.00 at the time and, thanks to your video, when it does expire I'll strip it and repair if possible and/or practicable.
These wifi modules are notorious for creating massive current spikes, most likely these spikes caused the capacitor to crap out and you removing the wifi module took away some strain on the faulty capacitor causing it to appear to function properly and putting you on the wrong track.
Just my 2 cents.
But as always, awesome fix, you keep amazing me, it's incredible what a guy with just a multimeter and common sense can accomplish!
Thank you👍👍👍
Great video. Loving the yellow mat action!
The jaundice mat. Really plays havoc on the camera's whitebalance
Fun video Vince. You are so darn flexible. I haven’t worked on the floor since 1995😀
😂👍
You have already got the confidence to do UA-cam videos, so you have proved yourself and can move into tv work. Good luck and go for it.
Third time I watch this video and the second unit I was able to fix thanks to your amazing instructions! Thanks a bunch, Vince, I'm forever your fan.
Yellow mat for the Seasonal Affective Disorder blues...
😂👌
I can tell you I have stopped buying electronic things from Philips just because of their bad capacitors and generally fault prone components.
When I spoke to the repair shops about this they told that mostly they had to repair Philips, because of bad quality.
A cap going bad after just 3 years proves that this is still a problem.
I own one of these, had to return one already.. it kept blowing on max speed, anyway, i love the device, sucks all smells from cooking, smoke, etc out of the air, you can use it with an app too
Vince can not use his with an app, there is nolonger a wifi chip.
I’m here for the yellow mat. ❤
Great job!
What annoys me about this device is the beeping when you press a button. I have it automated and woke up a few times from it.
Thanks to your teardown I know how deep in the filter that beeper part is soldered and that I will probably just give up on removing it…
That black center piece most likely clips in and you can't tell where the clips are basically they press it down from the top and it locks in with out releasing the clips it is never coming out with out breaking then the top plastic touch plate is adhered to it
👍👍👍👍
1/4 new price is a bit of a risk. It could be complete trash and worth nothing! For me it has to be more like 1/16 new price but that's just me. Keep in mind that the new price includes the expensive filter in NEW condition.
My grandfather actually helped invent the machine to make those flat ribbon cables!
the wifi board was pulling just enough from that capacitor to shut it down and when removed it was just strong enough to run poorly for a while. wild.
11:30 - Check your main cable for breaks. If cap wasn't charged then maybe the board wasn't getting power.
The caps near the 5v/15v socket on the power supply pcb look slightly bulged.
Called it.
They work good what bites is the cost of filters. I’m glad you have it fixed. ❤
A worthy try, cos it might have worked. I remember seeing the wires from the pins in the IC10. Bit before your time, Vince!
You could use blu-tack to help you put the screws on reassembly.
Great video Vince, I don’t blame you for assuming it was the Wi-Fi card, it seemed to make sense.
hey Vince there's lots of Dewalt Toughsystem radio's flying around that only work on 230v and not the battery I think that would make for a interesting video. awesome video again
the capacitors may not be hot, but they will be running all the time, and some components, even when new, will deteriorate quicker than normal, though, having said that, it could be a faulty capacitor from the factory.
Nooo! Pesky capacitors!!! Great fix, again.
We had these in the school I went to. For this task they were kinda unfit because you can very easily put paper in the top of those, which makes them make a ratteling noise
Vince you can always look up data sheet on that chip on the Wi-Fi board ... And find out the values of the capacitors and resistors that flew off
You can check the mx1290 datasheet. Almost all pin on this chip are IO. I would put a 1k resistor at all missing places. This is high enough to work as pull down or pull up resistor and low enough to conduct logical signals.
But probably it's just too small to work on.
On the power pins you put a zero ohm resistor. (If there is a resistor). Do this only on connections between the power pin and the supply.
Were they "Philips" screws?
You can get that wifi board salvaged from a old Microsoft wireless keyboard. I would verify if both are same pinout and inform which model number it is. Once i did the same for a Phillips Bluetooth radio clock and was the same construction as you shown in the video.
It is usually a wifi+bluetooth module from family of esp32 chips.
That bloody yellow mat. Great fix though Vince.
Maybe you should get some "helping hands" or "third hand". They are nice to hold stuff while you measure or solder.
Not entirely sure if i use the right words since english is not my native language, but according to amazon the right stuff shows up.
even if you looked up fix it video's on anything with wifi, then usually find it is the wifi causing the same sort of issues, so a very easy mistake to make as well Vince, also a reminder to always use captain tape around the work area to stop other components from flying off. but yes once you eliminated the wifi board, then you should have just let it run for the few days to totally illiminate it, as if something is on it's way out, then will present itself in a few days, and yes I said to myself it is boot looping with the number of times turning itself on and off during this video, maybe it was boot looping trying to find the wifi card, or because of a different problem.
Was great fault finding and fixing.
I have a dehumidifier from LG and when I removed the front front grid with its display and buttons attached, the metal fins looked like a sheep... loads and loads of dust.... I wonder how the dust gone through the filter... I had to vacuum clean the insde to remove all the owl built...
Howadays, the dehumidifier works as usual but it doesn't timedly switch to discharge the internal reservoir below the metal fins.... it basically works drop by drop directly from internal reservatory to the bucket at bottom.
Have the mini version - filters lasting for 3 years is a bit of a laugh because mine has had two replacements at around £40 each. Mine is currently unplugged because well basically it doesn't seem to do much....
I would be happy its doing its job
Thanks Emma👍
We had a 4000i Modell on our Workplace. The same height with Colour LCD Display.
Its from 2019 so its 3 years old. Warranty is over so it can go broken so ppl buy a new one.
Thats like a "timebomb".
TVs and Laptops have that also. Alot die like 6 months - 1 year after warranty, and if you check whats wrong its most likely a 1€ part that goes bad.
Hi Vince, thanks for the video, it seems like Phillips got a bad batch of 16V/470uF capacitors, mine seemed to be competing for the worst state possible, both had over 800uF capacitance 😂😂
Awesome repair!!! What a pickup!
Thanks Chris 👌👍
Great vid vince
I still want to know how to assemble/disassemble the top display board. I'm just curious now.
Also for that wifi board you can get them pretty easily and for cheap but you'll have to program it as well. You can read the code off the old board and program new one.
Never paid air filters much attention but this video has me thinking a home is healthier with one. This unit is amazing. Nice fault trouble shooting.
I wouldn’t get this one its very expensive
This was a wild one. Great fix. I love your evil plan to use it to tell anyone she or he stinks🤣
these are only designed to remind you to purchase new filters often, cost nothing build in a factory shipping is still cheap but you pay in gold.
Well done Vince ☺️
I think that when you disconnected the the wifi module you removed some of the load and the capacitor was able to keep up with the ripple for some time.
That was probably the missing (4.7v) 15 v line, When there is a lot of ripple the voltage will read lower.
👍👍👍
Great fix indeed. I did wonder if it was meant to boot loop earlier. And when that capacitor finally built up enough charge it then stayed on. Wonder if the WiFi board took just enough voltage to drop it too low to power up with that shoddy capacitor. Out of curiosity does it now read 15 volts rather than 4.7?
Thanks Paul, unfortunately I didn't check after the capacitor replacement. I'd like to think that it would read higher now 👍
Haha... almost same story I had... was tracing problem on smart speaker... using fancy thermal cam and all... turned out to be bad electrolytic caps. And yes that device wasn't that old either... The good ol' cap "plague" 😅
Great vid and fix! But I am, as a Dutchie, ashamed of how cheaply Philips products are made and how expensive they sell. I avoid Philips at all costs and went for a Winix Zero purifier. Korean made, runs 24/7 for 4 years flawless and can be completely taken apart in 5 minutes. No hidden clips etc, just screwed together.
We need a My Mate Vince Keychain sound board. Button 1. This is a complete utter mystery to me.
I hope you vacuumed the filter outside. The vacuum filter would not catch that fine of particles. You would just blow them back in the air.
hi vince top marks mate u no i love these fixes and tea break repairs hope ur well :)☺
Thank you George👍👍👍
Another great repair Vince!
A gadget for the ‘worried well’ 😄
Oh Vince, you and your circuit boards; you little scamp (Tousles hair) 😆
i have one of them, was repaired under guarantee , power module went, may be a fault with them, good unit though, slightest smoke in the room abd it goes in to turbo, app good as well
the wifi chip you need is (emw3080) read the sticker on 31:57
Nice score on repair Vince ❤️
super fix Vince :) awesome job with the fault finding :)
Thanks GDaddy👍👍
Have mine (a cheaper air purifier) on percentage air quality and when a friend vaped in the room even with window open went down to 0 percent and fan went to absolute max. Took about 5 minutes to get it back to the usual 95. In the kitchen it will also ramp up and if the dog shakes also sometimes does too. Most of the time it's on low. Can't see how it can filter much of the room when it's that quiet. So I sometimes I put mine on high manually for an hour or so.
Can you show how to open up and clean the fan? Thanks!
Is 'The Yellow Peril' going to make a comeback anytime soon lol.... great video btw!
😂🤣
A lot of wifi cards are essentially the same.
They are fitted in loads of machines, a maufacturer is not going to design a wifi card specifically for their machine if it is cheap to buy
These purfiers are clever machines
Thank you👍👍👍
I really want you to finish it and get a new Wi-Fi card ...
Please do it don't let us wait
I think Vince needs to fix a new toaster! 1.48, lol
