Anyone know why Louis didn't show up on my notifications tab? Bell is on all, checked everything... ?
I've seen the same thing where I discover new videos on Louis channel before I get notified of them. My guess is that CZcams staggers the push notifications Because sending to 1.61 million people at once would stress the system.
Susan W hates board repair
Probably because he’s trying to provide people with useful information and may be “abrasive” at times.
They don’t want you to feel suppressed so they suppress his recommendations.
Also like and subscribe
Uh, i just checked because i noticed the same thing, turns out i got unsubbed
Try turning the bell off and then on again. Also, check if CZcams messages are allowed in your browser. If none of that works, maybe try unsubscribing, then subscribe again directly afterwards (as well as turning the bell on again).
Never seen anything like this before. No response on the charger, and a literal "bug" in the hardware. LOL! enjoyed the video
It's literally where the name came from, bugs getting onto old computer punch cards and changing the code by covering holes
@@wardenpotato to add on to that it was Rear Admiral Grace Hopper that coined that term!
Thanks to you, they are discussing right to repair in Algeria's parliment on electronics and heavy industries. They will also discuss warranty problems.
theres something about these repair videos that just makes me feel happy.
Back in the day when computers ran on relays, insects would get attracted to the heat and get stuck in the relays. programs would literally get a bug in them.
They still like to die in the high voltage part of the desktop PSUs
Technically, that came from the vacuum tube era, but yeah… literally a bug.
thats how the word "bug" appeared in pcs
back in the day before programs. oh wait, this still happens, rodents get attracted to the heat and build nest right in your electronics and get fried when turn them on because they made a ground contact or chewed up the wire sheath.
He found the bug...
*punchline drum sfx*
Get out of here
This is what we love to see! Repair videos! Not some Qanon conspiracy theory "agenda pushing" bull crap he puts especially about the vaccine and COVID-19.
@@woahhred I guess you can't have a nuanced opinion in 2021 without being called a Qanon or a conspiracy theorist. Good to know.
@@theodiscusgaming3909 Not really an opinion if people are using it as a fact now is it?
I've been doing repairs for a while, but mostly by replacing whole parts and less on the component side unless it was a large through-hole capacitor or something similar. Recently I've gotten into buying parts laptops from eBay and have had some success getting nice modern machines for cheap. Now I've got a hot air station, microscope, nice soldering iron, flux and I'm eager to learn. The price for entry was also much lower than I thought.
How much was it all total?
My last big repairs was replacing some caps in a monitor. Still runs to this day.
@@Sir_Ninonino Around $150. It’s all the basic crap from Amazon, but they all work as they should.
@@Collinormous Damn, it is cheap.
@@Collinormous what kind of iron did you get? I have a Weller SP25NKUS, and do not recommend for repairs like this. It's just too big.
0:59 Yes you do, it is called an EKG stress test.
31:31 Another bug. in the middle about a 1/3 of the way down.
But before the EKG stress test, you always want baseline data.
@@MonkeyJedi99 EKG stress test are baseline data generated by a technician to be given to a cardiologist for interpretation and resolution.
MORE FLUX! I want to see that stuff EVERYWHERE!
I do these repairs here and there as a side hobby, as I enjoy it and it makes me feel like I actually helped others. Louis’ videos are always a teaching moment. Just just for repairs and how to find the issue, but for just lessons on life in general.
Wow... Entomology & Etymology all in one video. Louis is a genius!
As always, even though I am just beginning to diddle with vintage valve gear at 58, I learned some thing or two and had fun watching you. Thanks Louis!
Definitely a hardware guy, that's the slowest debugging I've seen in my life!
now I truly understand what "debug" means hahaha
tbh Louis Rossman's nothing compared to the guys in China. They can UPGRADE a SOLDERED cpu from i5 to i7!! They can UPGRADE soldered RAM!
@@bobjones1999 well they live on the SOURCE of the materials, they can actually do this because there they can have easy access to these components. I believe Louis can do this, if he have proper materials and equipment, altough since there is no such oficial store for these kind of components and you have to rely on donor boards, he would need to import them and since takes time and he have to rely on the component being good, I guess would be not much worth...
also changing soldered ram and processor could also need to change some bios setting I guess. but is doable.
I was always thinking, if I could change my 2015 laptop amd gpu for another one of same era and generation but stronger or such...
@@MrLuigge true. But for even in china they don't use up that that mcuh of extra parts. But u do have a point
@@MrLuigge Tbh to his hands are pretty wobbly
Great life advice in this video. You can't expect others to figure out how to do things for you. The first step is to figure it out yourself.
shilling? you are not shilling my friend, thats just simply helping the world.
I have dug several computers out of the trash. One was a server from a vets office that was stuffed full of fur. I replaced the motherboard for less than $20 and then sold it for $75 on Offer Up. I rescued an E-Machines desktop that had a bad hard drive. I took it completely apart and got all the goo out of it and it worked great after replacing the hard drive and still have it to this day. I also rescued an HP AIO printer that was full of water. I tilted it over and let it sit for a couple of weeks. I came back and cleaned it and it powered on and initially it wouldn't work. I removed the ink cartridges and cleaned up the contacts and it came back to life! It's amazing what people will throw away!
Fun fact: the term "having a bug" in relation to computers actually originated from that exact situation.
Back when "computers" still were high voltage and pretty bug a real bug found their way in from time to time, creating short, getting fried and Killing the system.
To make it run again you had to "fix the bug".
That's at least the story they taught us 15 years ago in school in my sys admin apprenticeship
That computer looks "bugged"
more like infested.
I'm so happy he saw the 2nd bug 🪲
24:55 "The one thing you haven't seen inflation is cheese".
Authentic cheese is always expensive and have been above my paygrade for years, even before the pandemic. The only cheese I can afford is the "processed cheese food", the one worse than American cheese.
Louis: "I just got scared because I touched a magnet and it made a loud noise."
To be fair, Louis... I thought that was an electrical shortage type of sound.
Remember that you cleaned the connectors with alcohol. That is probably what fixed the power issue, not the bug. imho
The buck converter is responsible for converting customer's problems into more bucks for Apple
or "bug converter" in this case :D
Apple would say consumer not customer
That soldering tip is incredible, thank you for sharing that Louis!
That's why it is called "debugging"
The term was originally coined back in relay computing days, a moth was found jammed between 2 contacts of a relay making it not work, the relay was later de-bugged (literally) and the computer worked, I believe you can read the exact journal/diary entry from the lady involved with the machine somewhere but I don't have it on hand, Grace Hopper is her name I believe
Nice job debugging that board Louis. Seeing the question mark folder was cool.
If you look on older schematics, there would often be screen-shots of what you should see on an oscilloscope if you probed that point in the circuit.
NorthridgeFix: Better than Factory
Louis Rossmann: Similar to factory, if not better
At first I thought Jon Stewart was repairing boards... :)
always good to see louis at the bench but at 1:54 is that a low blood sugar tremor and not something else. stay well.
0:40
"Check the heart. Check the... check the... Is it the brain?"
"No sign of cardiac anomaly or unusual brain activity"
"Okay. So it was poison?"
"My diagnosis is that you've experienced a severe anxiety attack"
"Me?!?"
(Iron Man 3)
Louis I love the honesty in your ranting!! Absolutely adore is because it shows you believe in the movement in growing and not in grabbing the pie. Best of luck brother, you dont need it though! You and many others believe in this as I and many others do!! :)
Louis: "Where there was a screw that was plugged into a connector."
Me: "So standard Apple connections?"
Louis, you always say nobody watches your board repair videos but I can't watch them if CZcams don't tell me about them! I absolutely love how they censor my notifications!!!! I have to manually check your channel every couple of days to see what youtube don't want me to watch.
as a software engineer, I found it incredibly interesting to see how someone would "debug" hardware.
There's a (possibly apocryphal) story that "bug" entered the computer lexicon when RADM Grace Hopper found a dead moth in a malfunctioning computer's relays. So it supposedly started with the hardware side of things.
Great video as always. Thank you for the additional comments.
i never wanted to learn how to fix phones untill about 10 years ago when my cell phones started to have problems after a year or so .checked out how much to get it fix i was like oh hell no,went on some forums read up bought the parts and tools and did it my self.im mechanically inclined and the tools have already been paid for from the first fix.
Haven't expanded to board part replacement yet, but have managed to mix and match screens, boards and cases, to make and resell custom nintendo ds. All because I was mad the hinge on my own broke and I wanted to fix it, and your videos convinced me I could do it
I love your plain talk.
whe he was younger, my dad had a Polski Fiat 126 (it's a car)
and at the time, you could go into a library, ora bookstore, and buy books on the car. They had technical info, detailed drawings, and walkthroughs on how to repair the most common issues. It was perfectly legal to publish those books. And he used them to fix his 126, and later his LADA, when anything went wrong with them.
I hope more people who work on boards outside of Mac. I have a 450 tomahawk max that has some strange quirks and I have no idea how to go about troubleshooting the board. Sadly I no longer live in NY so I can't go to one of your workshops. Looking forward to the wiki growth.
its got flees. by the way thanks for your detailed wiki pages makes the future brighter for the repair sector.
Inspiring, Im ok with a screwdriver so I got a MacBook Pro (13-inch, Late 2011) from ebay and had a go at fixing one fan worked second one was broken, brought a new board, wifi card, SSD SSD/HDD cable, 16Gb of Ram as the clips on the original were broken, SSD, Base Cover, Screws. has the graphics card issue. 3rd Party charger and I have a working MBP. I didnt realise the WIFI was not working till i looked closed and realised the Ribbon cable had been ripped. spend around £500 including the MBP which has a working screen and keyboard etc just internal parts after a few weeks of parts arriving, got a fully working MBP. If your ok with a screw driver and can organise screws anyone can do basic parts replacements
1:52 the struggle is real
Don't think that everybody is like you, bless your heart!
A real living bug or two?
Louis you don't wear as esd strap.
When working on such boards I always use a strap and an esd mat all linked to earth.
Have been told that assembled boarders don't need this but I'm old school and rather be over cautious.
Thanks for you right to repair and Apple repair.
I was always told that Apple machines were buggy and now I have proof!
Louis doing a historical reenactment at the beginning of the video, demonstrating how the word "bug" entered the technical lexicon.
How to start?
Step 1: Buy the minimum equipment - a table to work on. A fan extractor. A hot air station. The 8 or so screw drivers you need for apple computers. Flux. Solder. Soldering iron. An ultrasonic cleaner & solution.
Step 2: Buy a couple of the oldest, cheapest, WORKING computers you can find. Take them apart, put them back together. Check that they still work. Take them apart, clean them in the ultrasonic, put them back together. Check that they still work. Take them apart, remove and replace a resistor or two, put them back together, check they still work. Take them apart, remove and resolder a couple of chips, put them back together and check they still work.
Step 3: Find a broken computer and see if you can trouble shoot it.
Step 4: Put up your sign as a repair business. :) Start buying the extra equipment - like Paul Daniel's software...
Hey Louis, how can you be sure that when you're pushing down on the chip and the excess solder squeezes out, it does not create a bridge between the centre ground pad and one of the periferal pads?
Great question. I hope we get some insight.
Yeah, like, are we sure it won't short anything?
I watch and listen to this guy.
i've been waiting for board repair video, thank you Louis
You're not Mr. Clinton!
Thank you for posting.
Secretly, literal bugs killed this computer causing it to have to go in for repair.
28:49 - 29:40: This is true. I learned my first programming language in 2013. When I first seen code I kept telling myself, "there's no way I'm going to learn this, I just cant do this." Once I sat down and took the time to dig in and attempt it I realized I COULD do it; and just needed to be willing to do it. Here I am 8 years later and know 4 programming languages. It's all a mindset and you got to set yourself up to be able to achieve what you want to.
Aligning TQFP128 EC in Lenovo would be nightmare for me with crappy hotair station and my unsteady hands. I've aligned it and secured by kapton tape and soldered it with iron. Looks like factory and works perfect.
That new york bug, "I'm walking here!"
Was that an original Apple certified iBug?
You got hardware. You got software. You gotta beware of dem tiny bugs.
This is my job. I hate it because I get paid 15.80$ in florida. I also work for the military industrial complex which bothers me how the government can pay so much for bombs but workers can't get paid a decent wage making and repairing these things.
I've tried to get other jobs as a diagnostic tech but when I go into other places, they always say "well that's a dying skill" then followed by some generic email stating they've found other better suited candidates. I feel like I've made a bad decision with my life. Good for you though Louis. Keep repairing the electronics that others want to keep instead of throwing away.
I hope you find something. Yes, the military industrial complex sucks. Eisenhower warned about it in his farwell address - he could see that what was going to happen.
@@vincei4252 thanks. I went to school after I got out of the military. I wanted to fix electronics so people didn't have to throw them away and it would reduce waste and be cheaper than buying a new device. I was mistaken. Most people will just buy a new device.
Thanks for your words and I totallyagree with you. I'm sure I'll find something.
PETA's gonna be gunnin for Louis now.
hmm was that a bedbug... lord hope not.. they are hell to get rid of.
Hmmm yeah that looks like a bedbug X2
clean electrical contacts with a pencil eraser. it's safe as it's non conductive, and it does the most superior job even over most chemicals.
God bless you Louis Rossmann
Wait you repair boards on your new York real estate channel dude has skills
Louis has the power to debug with voice commands.
I loved the MGS Alert noise lmao
dont ask just post, its easier to decide its irrelevent and remove it than try to judge it before hand.
Cant tell if its a bedbug (probably) or a spider due to the video quality. If you can tell or not the difference clean EVERYTHING with heat! Some of the small flakes that looks like dandruff can be eggs.
Louis, you got any open positions for a hard working, patient, educated repair guy from south africa like myself? I dream of working for a company like yours. How do I apply ?
By making $92000 in back rent debt disappear & doubling walk in business. Magicians feel free to send an email to louis@rossmanngroup.com
@@rossmanngroup you are expanding to sales and marketing apart from CZcams now. Are you now becoming an Empire?
This is asmr to me
Through the eyes of a board repair tech that bug was HUGE!!!
that big was big
@@Collinormous thanks lol
wow he’s fixing a board. been a while.
Blind hope often make wonders. Because it keep our mind focused to task or simply prevent us to fall into despair and frustration.
Which kind of solder you are using here?
Louis if you taught a course on electronics repair 101 in one consolidated structured way I'd pay for it
Wait this channel has hardware repair videos?
this mb is bugged apparently
This is ASMR level content
I learn from you, thanks.
Like how he found bugs :)
I learned something.
We must share
New here,
Is there a risk of touching the soldering tip to the board? 23:57
When people come to pick up their device do you give them a link to these videos showing how you fixed it?
Nice video! Hmm, what's preventing the middle pad solder flowing out when you press it down, to make bridges between the pad and the edge pads, or between the edge pads? Always was afraid of that kind of issues, when soldering stuff like that...
it's gonna be 10x better as long as you use leaded for BGA :)
Ross - anyway to upgrade 2018 MacBook Pro ram or SSD?
When is RossmanCookies opening?
This man is doing God's work.
Louis, time to spot with the coffe and start with Mg+B12 supplements
Glad you got the spider before it escaped and you had to burn down the whole shop.
Not sure it was a spider. It looked like a tick at first glance and we later settled on it neing a bedbug which is something you don't want in your store/home!
Freeze spray, alcohol, or acetone for the critters. Under the scope is fun to watch !!!! LOL Cruelty to critters essay.
I'm surprised you don't send all the devices through some sort of bug killing method. Either an oven at like 150 deg or some sort of chemical fogger.
I know I plan on doing that to any future used laptops I buy. Just to make sure I'm not introducing roachs, or like bedbugs or some shiitittt into my house.
Another bug ran up towards the top and went behind the battery.
Why do you call the mb logic board? Is there a specific reason?
Two other buck converters: A change machine, and a wildlife castration specialist.
For those of us that may not be so versed in component level repair, but are good with software troubleshooting & hardware repair, is there anything we can contribute to the wiki?
Today I learned debugging can still mean what it originally meant.
11:10 obviously has never had his eyeballs glued to sticky tape before 'it only hurts when i try to move or blink!'
Speaking of Paul, where is he? I haven't seen him in vids for a bit.
Louis, is it common for apple laptops to have many issues or has it always been that way? Just curious
There was a problem with the bug converter
