For folks asking about my USC setup, I currently have deionised water and ULTRAsonic Pro Electronics (flux removal) fluid in there, but that specific fluid isn't on amazon anymore, so not sure if it's discontinued. I generally look for something that's designed to deal with flux and electronics though, rather than just jewellery or engine parts. Jewellery cleaner would probably be ok, but be careful of engine parts cleaner as that might be too vicious. After cleaning I blow-dry, rinse in IPA, blow dry again, then air dry.
I worked for Philips USA many years ago. We literally put our new boards into an ordinary dishwasher for a full cycle to remove flux with no dangerous solvents. Boards came out clean, no flux and fully functioning after 2 hours in a dishwasher! We did this as part of the production process. The only things special were the racks inside to hold the boards. We did use de-ionized water and a particular brand of detergent, I don't remember which it was. Also 48 hours of air dry.
One of my favorite computer repair channels on youtube. There are so-called techs who have 30 years in the business who can only swap cards and can build computers but they can't touch you on actually FIXING a computer. Card swappers are imposters! Keep up the great work! I like how you quoted Louis Rossman - another great computer repair guru who is one of my favorites!
Done watching, thank you very much for the informative review video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE EDUCATION. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.
After having produced a batch of boards and cleaning them in the ultrasonic cleaner (tap water + cleaning agent), I tend to rinse boards thoroughly in a large enough container of distilled water (removing possible calcium residue) after which I rinse them in a container of IPA. By doing so, I replace all the left over water with IPA. IPA evaporates above ~ 78 degrees (C), so putting boards in an oven at 90 degrees (C) will take on average about 5 minutes to completely dry them. Without an oven I estimate it will take about 20 minutes at room temperature due to the IPA. Shake regularly in this situation. Don't stir. :-)
good job with connector ! :) and when laptop turned on first time i was no shot! haha amazing i would spens so much time cleaning checking shorted pins etc :) but us cleaner did crazy good job how bad was looking that board. GGS bro
After ultrasonic you should give the board a bath in 100% IPA, this will disperse any water left on the board and of course let it bake in the sun for awhile.
You and I both know; tea is nice to drink but electronics don't drink it. That rice probably halted further ingress of liquid to places it shouldn't be. So bottom line is . . . (contrary to your bold statement) rice does work. That's why it was repairable.
Have question about randomly bluescreens in windows 11 "even after fresh install" while using or after using Windows Update? I was busy with a laptop, after disable automatic update in windows services the systeem crashed several times and destroyed the windows start menu. What may can caused the issue? I put new thermal paste on the cpu and gpu. System is not overclocked, maybe memory or wifi controller?
nice video as always well explained graham, one irritating thing for me was the camera hunting on your intro, just thought i would mention it in case you can adjust it i assume its the gimble one?
16:03 👍😎 What cleaning liquid mixture do you use in your ultrasonic cleaner? I would assume something like isopropyl alcohol 90% with some little bit of surfactant.
Once again a great video, really surprised that you got this to work considering the amount of liquid damage. I'm looking at getting an ultrasonic cleaner but I'm not sure about cleaning solutions, may I ask what you use.
Thanks for the good videos as always have enjoyed your videos for some time now and have been a great help in getting myself set up with equipment and get into motherboard repairs as most of my electrical work was done on old school stuff TVs VCRs and so on but gave it up years ago so now getting the hang of working with components the size of a grain of sugar haha Currently working on an Asus laptop that for water damages during a typhoon when roof blew off almost an year and half ago it had been stripped and dried out not long after it took an unwanted shower and has been sat in a box since as not had the equipment and time to do anything with it and now the missus wants it fixed personally I would of happily thrown it in the bin since it's getting on now and needs replacement hard disk possibly DVD drive But the motherboard J's working the main issue with it is the screen cable it got kinda BBQED on the 4 + pins on the screen now I'm debating if I should get a replacement or just solder the 4 wires directly onto the 4 pins at the back of the connector as I'm sure the missus wants to save money The issue I do have is when that cable shorted out and cooked itseld it also blew up a ferrite bead that connects between the 19V rail to the screen power and that ferrite bead literally blew to bits so much so it took a good time to figure out what it was until I found a schematic for it My issue is trying to find a replacement ferrite bead and in this country trying to find anywhere that sells components of the SMD type is near on impossible and ordering online I can only find like 50 pieces and obviously I only need 3. 1 to replace and 2 for backup If I can resolve the cable problem either by replacement or soldering can I get away with just putting a blob of solder where the ferrite should sit this obviously would only be for testing purposes and not permanent have heard of others just bypassing it with blob of solder but on a lower voltage and lower current draw am aware that ferrite beads are meant to be to get rid of unwanted noise on the DC circuit I'm not really that familiar with ferrite beads as that's never something I have ever had to replace in my long history in electronics Any tips would be much appreciated Thanks
Hi Graham, I have question buddy please! I have a lenovo desktop device which has a 10 pin power supply. I'm willing to use my 20 pin power supply I'm actually willing to do it without using an adapter for the sake of learning and saving some unnecessary spending especially for the shipping of a tiny adapter, doing just trimming and soldering and taping stuff. 1st do you recommend doing that? 2nd is it different from the 20 pin guy in terms of voltages? much respect for the content your giving us bro....
When I saw USC = (University of Southern California) in the video description I was very serious and I am not an American citizen. For this case: Is it correct to assume that it means Ultra Sonic Console? Because if that were the case, I think it would be better UCM = Ultrasonic Cleaning Machine. I am only trying to make a constructive comment due to the enormous respect similar in size or even greater than the gratitude that this humble Latino subscriber feels for you due to the valuable content that you selflessly share with us. A brotherly greeting from Mexico.
I've heard them referred to as UltraSonic Cleaners many times, which is a bit odd to me as well, but that seems to be the term in the repair community...
Do you ever use a compressor to help with drying? I found that it helps to blast out water from underneath components and in tight fit spaces that can otherwise be hard to dry. At least for old retro and through hole that is the case. I know a lot of chips on the Macs are under-filled anyway. Edit: I don't think you should give all the credit to the ultrasonic, that capton tape shim was pretty impressive. And yes, you made it look easy! I remember having to use a thin piece of plastic to make a keyboard flat flex make contact in one of those latching connectors with a broken latch, it took ages to get it right.
Yea my normal strat in the winter is to airblast the worst of the water off, then alcohol rinse and airblast again, with the hope that the alcohol will displace water under any chips, then airdry for 30mins or so.
I got a wierd case, my PC won't turn on but it geting power from psu looking from the LED on motherboard, tried to short the power pin and still it wont turn on. Check the power pin i got 3.3V. i though maybe its my PSU but no. Unplug all PSU cables, shorted the PS_ON on 24 pin to ground, turn on the PSU, PSU fan spin, check 1 by 1 the voltage on 24 pin, all 3V, 5V & 12V is present. Still my motherboard doesn't want to power on.
That initial test was with my SSD in. I was going to start doing data recovery on the customer's SSD in another macbook, but then when this clean up was going so well I deemed it not needed and put the customer SSD back in.

How long do you put the board in for?
About five minutes is usually enough, if not, turn over and give it another 5. My cleaner seems to get both sides fairly well.

We did use de-ionized water and a particular brand of detergent, I don't remember which it was. Also 48 hours of air dry.
Did they use regular tap water or do you think they had a de ionised water supply for this process?
I'm sure they would have had a direct supply of deionized water. Tap was has salts

Inspirational as usual Graham, the backlight fix was brilliant, I would never have thought of that one.
Awesome video man. I was cheering with you when that backlight worked.

Really nice work, loved the captain tape on the display connector!!
Very creative loved the tape fix on connector

very well done the work was all done by you i was routing for you all the way through i cheered when it all worked how said am i :)
Great videos for someone like myself learning or a more advanced, entertaining.
Spilling tea on your laptop is one of the most British ways of damaging it I've heard.
ultrasonic trick saves the day along with some good dx work #capstan
Great work Graham, but I'd be giving it back to the customer with lots of caveats !!!
what MacBook series it is ?
About drying PBC boards, I usually wash it with 100% alcohol and then use a vacuum oven at about 25-30 C for 1h
You and I both know; tea is nice to drink but electronics don't drink it.
That rice probably halted further ingress of liquid to places it shouldn't be.
So bottom line is . . . (contrary to your bold statement) rice does work. That's why it was repairable.

One very lucky customer. Well done Graham.
I'm pretty sure you could dry only really, really small PCBs in an Easy Bake Oven.
nice video as always well explained graham, one irritating thing for me was the camera hunting on your intro, just thought i would mention it in case you can adjust it i assume its the gimble one?
great video Graham got extremely lucky with this one
Skills, enjoying your channel. The easy stuff is watching you.
16:03 👍😎 What cleaning liquid mixture do you use in your ultrasonic cleaner? I would assume something like isopropyl alcohol 90% with some little bit of surfactant.
Deionised water and a USC additive designed for cleaning flux, generic stuff from amazon.
@@Adamant_IT .. Thanks for the information. I look forward to your next video. Have a great day!
@@Adamant_IT Got an example/link for that "USC additive" ?
Wow. Impressive fix. Loved this one.

Currently working on an Asus laptop that for water damages during a typhoon when roof blew off almost an year and half ago it had been stripped and dried out not long after it took an unwanted shower and has been sat in a box since as not had the equipment and time to do anything with it and now the missus wants it fixed personally I would of happily thrown it in the bin since it's getting on now and needs replacement hard disk possibly DVD drive
But the motherboard J's working the main issue with it is the screen cable it got kinda BBQED on the 4 + pins on the screen now I'm debating if I should get a replacement or just solder the 4 wires directly onto the 4 pins at the back of the connector as I'm sure the missus wants to save money
The issue I do have is when that cable shorted out and cooked itseld it also blew up a ferrite bead that connects between the 19V rail to the screen power and that ferrite bead literally blew to bits so much so it took a good time to figure out what it was until I found a schematic for it
My issue is trying to find a replacement ferrite bead and in this country trying to find anywhere that sells components of the SMD type is near on impossible and ordering online I can only find like 50 pieces and obviously I only need 3. 1 to replace and 2 for backup
If I can resolve the cable problem either by replacement or soldering can I get away with just putting a blob of solder where the ferrite should sit this obviously would only be for testing purposes and not permanent have heard of others just bypassing it with blob of solder but on a lower voltage and lower current draw am aware that ferrite beads are meant to be to get rid of unwanted noise on the DC circuit
I'm not really that familiar with ferrite beads as that's never something I have ever had to replace in my long history in electronics
Any tips would be much appreciated
Thanks
Well done! Cleaning the board first probably saved the customers laptop from shorting something. Your experience was key.
You’re a true wizard Graham

much respect for the content your giving us bro....
I know adaptors exist, so if you can find the pinouts, you could probably mod it yourself... no idea about the conversion myself though tbh.
@@Adamant_IT Thanks Graham 🙏

I beg to differ, rice does work very well with a nice curry and naan bread
What liquid do you use in your ultrasonic cleaner for pcb?
Oh my days mate. Someone should tell them to dunk biscuits in their tea instead of computers...
hey been a Member for 2 years, 3 months, 19 days
Great job love this channel.
Great stuff, well done my good man
Nice repair. Nice video. Love it
Nice ultrasonic cleaning machine.
You must have had Lucky Charms for breakfast.

a WIN!!!! success is great
Wow. Well done.
Would the capstone tape get stuck inside the connector when pulling out?
It's possible, but at this point if that plug needs to be removed again, it's going to be because the connector needs replacing I think...
Another amazing repair.
Whats on your ToolKit Flash Drive for desk top and laptop repair. ? Can you send me one?

And CMOS batery is 3.1V
Brilliant fix.
This was entertaining
Very lovely
Incredible...
Wait, so who was the customer that spilt tea all over it, given that there's a user account with your name on it? 😆
That initial test was with my SSD in. I was going to start doing data recovery on the customer's SSD in another macbook, but then when this clean up was going so well I deemed it not needed and put the customer SSD back in.
why not rinse the water off with alcohol?
Did you say "tea" or "pee"?
I definitely did a double-take when editing and was like "wait, I did say TEA right? That's what I mean to say..."
So, tea *without* sugar then?
the missing information is what type of tea!
5:50 twss
that was an easy fix ;D
can you not just replace the LVDS cable entirely, rather than attempt to reconstruct that one?
Its build into the display so that makes it complicated
Wish to buy a used hp 360 laptop?
*spilling liquids on keyboard...tnikpad users do that for fun*

Too modest young man, NONE of this was a nice and easy fix. From knowing that the US cleaner was the best bet to finagling a micro-connector, awesome.
