Thank you sir. I have a Sonicare diamond brush and with you help. I have been able to fix it, saving me over a £100.00 already. I appreciate your lessons. Cheers.
Nice job! Glad you find it useful!
@@letsfixitgarage I was a car mechanic buy would have never attempted doing this until I watched you do it. Bless your soul sir.👍
Thank you very much for your help and the precise description of the test points. I have just repaired my Sonicare connecting a thin wire from the test point of the button directly to the resistor. I have also added a few of silicon on the broken rubber o-ring. I do not know if it is a good thing but everything is working properly at the moment.
Glad it helped. but I would definitely replace the upper seal. there are some links in description its not that expensive and chance of getting water damage again will be significantly lower ;)
Thank you for this series of videos. I have a water damaged brush, with one MOSFET getting very hot on the Deep Clean (last one) programme. I even get a wisp of smoke from the PCB sometimes. you mentioned about shorted MOSFETs in the video - do you know what might cause this? Is it track damage under the MOSFET itself for example?
Water damage is quite unpredictable.. it could be long time contact corosion or simply water droplet shorting mosfet out.. smoke could be coming from element itself or the pcb track burning through.. I would clean it in ultrasonic bath and afterwards clean it with alcohol then check what damage it has.. elements, tracks.. if mosfets burned through question is it resonable to repair.. maybe use it as spare parts donor..good luck in repair!
@@letsfixitgarageThanks for the tips. There isn't much visible water damage and the battery is still good - but keeps getting discharged due to the brush starting up randomly. I will give it a good clean as you suggest and maybe replace a FET if it comes to it!
@@iwbnwif if it starts up randomly inspect/replace the main button. It could be that water inside is randomly shorting it out..
Thank you very much for the videos. I've manage to repair 1 brush but not sure is it because of my repair or from the water but one of the LED seems burned (almost no light). Are they replaceable or is not worth the effort? Cheers
Your welcome :) Sure it can be replaced. Just look for a right replacement (size, colour) or take it from a donor but be carefull with soldering time, temperature they are quite sensitive..
Thank you so much for your videos! They are a life saver. I recently took my Diamond Clean apart to change the seal. All went well - I put it back in its casing but when I pushed the button, it would light up for a second and then die. So I thought maybe it needed charging and so I put it in the holder (without its casing) and it started flashing. Yay! After an hour or so, I thought I'd just check it. It turned on, vibrated - all perfect, all very exciting and then abruptly stopped dead. Now it won't charge - it won't turn on. I am so new to electronics and don't have any real tools but will order some. I just don't know where to even start. Does it sound like a fuse? Could I just need a new battery? If it was water damage and there was water somewhere I couldn't see, would it stop it charging? Any guidance at all appreciated. In the meantime, I will continue watching all your videos!
Hi! Check my video for water damage and check MOSFET control traces to the chip and MOSFET itself if it's not shorted.. usually water damage is under the board not upper side.. but again if it doesn't turn on at all it could be the fuse or even some chip that burned through.. these kind of damages are difficult to advice without seeing the board..
@@letsfixitgarage Thank you so much! I will get myself a soldering kit and get the PCB out :-)
You might want to check the connections on the battery. The tab welds that connect the battery to the board can come loose. If you take a small screw driver, you can lightly push the battery under the PC board. If one of the tabs are loose, the battery will pop out. That was the issue with mine.
@@handydanny1315 Thanks so much! I'll try it out!
These videos are very helpful thank you. Mine is not powering on. My PBC is PBCR3. I get continuity between the power button TP1. When I use my meter from the hole to the right of the power button to the longer U1 chip it powers on, so I assume the path to that chip could have a problem. What points on the board would I solder a connection to and from? Can you remove the board without un soldering the battery connections? I'm able to detach the upper black clips but not sure on the lower connection. Thanks.
Yes the path from button to the chip is broken. Usually under the button on the backside. So when you will take off the board just connect the test point to the track beneath it or run a jumper wire from button contact to the chip or the point that I show in the video.. and to take off the board you need to desolder not only the battery but also two points on the charging coil.
fantastic detective work
my son has one thats broken exactly as you highlight ( TPH failed) and the traces are too small for me to resolder !
are you able to source or sell your repaired pcbs?
Everything's posible, write me an email, it's in channel description
Hi, what wire do you use to repair the traces?
0.02mm uninsulated wire. Or at least that's what the Chinese declare, haven't measured it..
Nice video. What do you think about repairing it and coating all the board already wired with silicone so it never happens again? Is it possible to buy some of your repaired boards?
I thought about it and I always coat the repaired parts with clear coating but I wouldn't bet my whole money on the coating alone. I'm principle original seal is very good protection if you take care of it. if you don't let toothpaste buildup on the seal it holds very long. if you start to see any buildup on the seal just replace it and you will not need to worry that whole brush is full of water and if not PCB then electromagnet will start to rust and corrode.. and yes I have some repaired boards, if you need some write me an email it's in the about channel section.
Hello! thanks for the videos! My Diamond Clean started to turn on by itself so I opened it and the magnets were together and also was kind of wet inside. I did not do much besides letting it dry and clean some oxide with a brush, but now when I connect it, it is buzzing/beeping while on its charger, one long then 2 short beeps. Do you know what can I do ? Thanks!
First off all I would suggest taking the board off it's plastic frame as there will be oxidation and damage under the board this needs to be cleaned to. Don't turn on the board till it's completely dried. And I assume the button will have some contamination inside so it would need to be cleaned too you can see how it's done in my last video czcams.com/video/vC-TKIwYcbI/video.html
@@letsfixitgarage Great I will try it ! also do you know where can I buy the tip seal that is broken to replace it? If I can not fix it do you think I can sen it to you or can you give me a quote of your services please; Thank you so much!
Check ebay or AliExpress for the seal.
Sure if needed write me an email letsfixitgarage@gmail.com and we can check if I can help you ;)
Молодец
Thanks your show. How to get the battery and motherboard from you if you have and sell it?
It's possible, if you are from europe write me letsfixitgarage@gmail.com
Great video! My toothbrush works fine but when put on charger it detects it but vibrates with 2 short beeps and 1 long one and doesn't not charge. If I hold the power button it stops for 3 seconds or so but then resumes the vibrations. Could it be a water damage issue?
Actually, for anyone wondering, I managed to fix this charging issue by taking off the power button and cleaning it. My guess is the power button dirt/water damage was causing it to be pressed while charging hence the 1 long beep followed by 2 short ones, usually that is enable/disable the easy start. Although reassembling the power button was a pain and I ended up having to use some electrical tape to keep it in place because a pin broke on the frame that holds it in place.
Wanted to write that it could be water damage on your first comment :) good job on figuring it out. If there was water I would suggest to take off the motherboard to inspect the back side. Especially if it's diamondclean model.
Hello. nice tutorial. i changed my toothbrush battery. now it works, however, after about 30/40 minutes it downloads. the battery absorbs me from 3.7 V to about 1V and obviously the toothbrush does not turn on anymore. what can it be? is it normal that connecting the test leads on positive and negative without battery, the tester sounds? thank you
You have a short on the board. Some kind of component should seriously heat up if it discharges in just 30 min that's how you can identify the bad component.
Ok thanks a lot
i have one about 3 years, when charging, the light is on but it doesnt work. so should i change the battery?
I replied to you in the other comment
There are many replacement pcbs on Ali express - is it worth just soldering a new one in? Would it work?
Well I would first go with repair attempt if that fails then buying new one from China is always an option, if it doesn't work, just claim the seller. I doubt that they have original code in these but on the other hand it's not that difficult to program few patterns when you read them out with oscilloscope :) so yes they are ok :)
Mine turns on, but the motor is vibrating wrong and makes a very high pitched sound. I cannot find any damage, but the inside of the toothbrush was full of water. Something must have shorted out, I just can't find it. edit: My board cannot be removed without cutting plastic, so I cannot inspect the other side. It recharges fine and holds a charge, but when I turn it on, the motor has that problem and the light flashes orange very quickly for about 20 seconds. Maybe it is garbage time.
You can press the plastic pins with pliers or just cut it off the ticker part and it will still hold in place. You need to look both sides as usually bigger damage in on the underside.. and yes water damage is difficult.. it can be anywhere..
Hello, I tried to clean sonicare hx6250-14 and the water got in (I'm so stupid)
Then it stopped working. After I disassembled it, it started to charge. Now I'm waiting to fully dry, and then I'll try to charge it fully. Is it safe to use it?
We'll try it out for at least few times without the housing.. if nothing heats up it could be safe, but with water you never know what damage was done..but from my experience it is quite reliable toothbrush with good components I saw a lot of water damage and components usually hold through..
I have a sonicare diamondclean of about six years old. It doesn't do anything out of the charger. When I put it on the charger, it vibrates twice shortly and then a pause and another short vibration. Seems like an error code. Does anyone knows what this means and how to fix?
Does the charging light glow yellow/orange? Maybe the battery is dead.. as the toothbrush vibrates when charge level is low. or if the upper seal is damaged the water damage would me my "favorite" defect.. that could be confirmed by opening and inspecting the insides..
I have had the same as this previously. It could be a nearly dead battery, or you can try a reset (hold the button in continuously for at least 5 seconds).
Hello do you know how to fix if It wont charge can you please make a video on this please and thank you
have you taken it apart? have you checked the test points that is in this video? 95% of the times it's water damage (especially on the back side of PCB) 5% defect on the board like charging IC that's very specific and difficult to find..
@@letsfixitgarage the. problem was first was it would not vibrate and while fixing that problem now it does not charge
Well if its after a repair attempt that something went wrong it's even more difficult to comment as I don't know what was done intentionally or unintentionally.. one suggestion would be to get a donor to swap parts or buy a new PCB that would fix the problem fast. I have a link in description..
@@letsfixitgarage is there any way I can ship it you for you to repair it
It's possible wirte me an email we can discuss the Details. Channel about section has my email.
Cannot take off head. I want to replace. will not come off with pliers. What should I do? Do I need a new Sonicare toothbrush?
What do you mean with head?
Hello, board 4235 020 43156 is faulty after flooding, mosfet assembly Q1 marked 1Z W88 is broken. Can you tell me the full name of this mofet?
sorry, I don't have it. I take them from donor boards if needed.
Привет!
Я смотрел какой то из твоих роликов, где тебе пришлось отмыть плату в ультразвуковой ванне.
Подскажи пожалуйста, какую жидкость лучше налить в ванне, чтоб хорошо отмывалась плата?
Спасибо!

Just throw it in a tub of rice 😂
at these stages rice will not help :) usually its days or even months of motherboard being in damp housing.. but good try :)
