I can't speak for everyone, of course, but I'm here to see some good old-fashioned board repair - and hopefully learn a bit about it myself.
Mission accomplished.
Louis ASMRossmann channel is worth
The sultry sounds of Louis Rossmann's voice combined with fume extraction and hot air keep me coming back for more board repair videos! And don't forget the beep of the soldering iron.
@@aazjo So sad, I love it!
@@aazjo Beep!
Louis, you have made repairing a MacBook more entertaining than my zoom meeting... I have not yet decided if this is a good thing...
Anything is more entertaining than a zoom meeting. The only time I ever use zoom meetings is for work, so...
@@StormsparkPegasus Yeah, my zoom meets are for college XD, I never pay attention to them though. I just take notes at my own pace afterward.
Yeah.... I wish i could ignore in-person meetings as well
Mmmm.. fair..
'Why would anyone come to watch your videos?' Because WE learn something, and learning is GOOD! Thanks Louis for another great video!
Every time you claim to have failed we all learn so much! Thanks Louis!
I like to make jokes like "a board repair on this real estate and EV channel?", but these videos really are entertaining to watch. Repair isn't always this interesting...your snarky commentary makes it entertaining.
I think the main reason is that more people can relate to real estate. Also his EV videos are interesting because it's nice to understand more about how employment actually kinda works.
For the MacBook repair videos:
I don't even own apple hardware.
OMG louis just uploaded and someone disliked the video, TIM COOK is watching :)
Love all the recent board repair videos! Thank you!
THANK YOU, you’re one of the only places I’ve found that actually gives advice on repairing the logic board on these older macbooks. Every other tutorial just tells me to use apples system diagnostics (don’t work on my mac) or gives basic troubleshooting steps that only allow me to rule out that it’s a problem with cpu or the hard drive
Yay Board repair.
Ah Louis has been off the bench for too long
The thing about failures is you can learn from your mistakes. Plus we humans aren't infallible, we make errors. But it's how we grow.
I've recently found your channel and I'm quite enjoying your content. Keep up the good work friend!
Well, I can't recall if you said it here or in another video, as far as why people watch you - you're one of the only people doing practical explanations for electronic repair. I also had the Comptia A+ book that gave that obtuse definition for a transistor, so I get it.
I think you're also one of the only people that gave advice for depression that wasn't the garden variety BS of "it's just like a light switch, be happy!" I wish you well, man. The board repair stuff got me soldering, the depression stuff helped get me out of a serious funk. Thank you.
I'm happy for you. Keep it up.
Well, something nice to watch while eating
Lies, nobody watches these
[Thanks for the description when you click on the title for details. Working with next to nothing tools here, at least I know what I'm missing and will hunt for. Keep up the fight, Señor!✌🏼💊]
If you want to move somewhere while prioritizing cheap housing, WV isn't too bad and there are bigger cities if you don't want to own a farm.
Love you, and your style! Love from Turkey!
Thanks for teach us…🙏
Love your videos got a very nice radio 📻 voice
A repair video - instant like after 2 seconds!
I am excited for a board repair. You provide so much information in an understandable way. Thank you
nothing more beautiful than a good ol PPBUS_G3 Hot fix
Long time watcher and glad to see the hand tremble from the last stream is better. Was getting a bit worried. Maybe just low blood sugar?
I tell you why I watch your videos, they are entertaining and at the same time in most cases I learn something from your videos so thanks for sharing it here on TH-cam Louis.
And I don't have a tv because everything on that thing is utter bullshit and I don't like that, therefore I have an extra reason to watch something online and you are a way better choice to watch than anything on tv to my opinion.
I forgot you still fix stuff!!
You are totally amazing 😊👍🌹
I'm a software developer and I still find these video interesting lol (even thou I have little do no frame of reference lol )
pp bus! PP!!🙌🏼
Ever thought about moving to the Detroit area? Great locations for good prices and there's a bunch of beautiful beaches.
Yeah beautiful beach on 3 mile and dequindre lol
@@wharjm01 Metro Detroit offers a lot more than the worst areas. All places have spots that need improvement. But Detroit does offer a lot of opportunities for growing companies and people considering we have the space and infrastructure now to accommodate so much more.
@@wharjm01 also, I'm not sure what beach you're talking about as Dequindre goes North and South and 3 mile isn't even a road people talk about. Typically, the beach is on the East side, meaning it's along Jefferson avenue. And there's lots of great places along Jefferson. Just look at Grosse Pointe as an example
Helena Of Detroit it’s a joke referring to all the empty lots
@@wharjm01 that's just space for opportunity! That's what makes the city such a great place for growth. That's why the property value is low enough to get exactly what you need without being raked over the coals.
Yes
Great Fix. Buy glasses 🧓Kidding. U the Man!
I'm amazed you made it through the video without a single "Debug" joke
I see PPBUS G3 hot in the title and I click instantly
Hey Louis. I just saw a Linus video about a company making user configurable Laptops called framework. And the one great thing I saw was that they are going to give out their schematics to repairers. I don't need to tell you how significant that is in your fight for right to repair.
It's a PR stunt. When the schematics are actually freely available to everyone then it will be truly repairable.
~Pretty tempering colors~
what setting on the multimeter are you using to do your readings and what is the exact value
I agree Louis, I live in the Bay Area and would never buy a middle class home for nearly a million dollars
I have one of these. It worked fine yesterday and today no power. I love and need my laptop. Buying a new one is not an option right now due to the cost. Sadly i live in the Caribbean far away from you to fix
It's not a fail if it works
nice :D
I don't usually have much time for longer repair videos, but they're lovely to watch. Out of interest, why don't you clear the pads of solder, apply fresh solder to only one pad, heat that pad (with your soldering iron) while placing the component and then solder the other side? Do the bigger components warp too much when applying direct heat?
It's more of a time thing. With SMD reworking it's faster to just tin the pads, add flux, place the part and hot air it into place. For amateurs, add the part to bare pads, add flux and solder one side, re-position if necessary then add solder to the other side and job done.
@@johnbos4637 I guess so, but in this case he already used solder wick to remove all the solder from the pads anyway. I get he used the hot air pencil to remove the diode from the donor board, but if you're trying to not heat up too many surrounding components a soldering iron works pretty well.
Edit: Also, most solder you get is rosin-core, meaning you don't need to add flux while soldering with an iron, only when reflowing.
@@ThisRandomUsername no, you need to add flux with ALL smd soldering no matter what, even if using an iron or hot air, you must use flux otherwise you will get a bad solder joint or at the very least it will look bad and amateurish.
@@johnbos4637 Rubbish. Dave from EEVBlog made a nice tutorial on how to solder SMD components. At 12 minutes and 7 seconds, he shows how you can get pretty good results with only the flux built into the solder: th-cam.com/video/hoLf8gvvXXU/w-d-xo.html.
I've soldered a lot of SMD components myself without extra flux and it's usually pretty easy to see if you've got anough wetting. It's always a good idea to go back to the first pin once the rest of the legs are down and resolder it in case it moved while cooling, causing a potential dry joint.
@@ThisRandomUsername LOL! eevblog is an amateur compared to professional hardware developers who solder prototypes every day or professional PCB repairers who work on moderm SMD PCBs every day.
Hey, would I be able to message or get in contact with you about how to troubleshoot my laptop? It takes a charge but only when it's turned off. I thought it was the charger port, would it really be the battery though if it still holds a charge? Thanks for your commitment Louis!
I find this kind of videos very interesting because I couldn't imagine how component level diagnosis and repair works. I have watched all your hours long video in the past 6 years. Btw. I can't image how you can complain about 800k housing prices. In my area it's at least double for a 1 br apartment in the city or are 3br house in the suburds.
Sounds like robbery to me. We have a 2k sq ft house for less than 80k.
OK is a nice state but may be a big change from NYC. The university of OK is massive and I’m sure would provide lots of business. I grew up in North TX and I’ve visited NYC prepandemic in spring, summer, and fall. The climate is way different but that’s only a little thing. OK and TX are some of the least walkable states. The climate and the way things are spread out makes it so everyone drives. OK and north Tx can have some crazy ice storms which is either cool af or terrifying depending on if your power is on. I really don’t know what the politics of OK are especially in regard to this business.
It’s not bad at all it’s just different and a worthy consideration tbh. You might do very well in OK. Hook em horns
Just an interesting note, but places like Portland, Washington, and San Diego as mentioned in your video, along with other west-coast cities have homeless population issues partly because homeless people know that (a) the weather is better there than in other regions of the nations, and (b) they're treated like human-beings more frequently.
Housing prices for both rental and home-ownership are skyrocketing for several reasons; chief among them being (a) Rental apps like Air BnB, and (b) Investment properties.
In the game of real-life Monopoly, rich people hoard their money and save it for what is a rainy-day for most people but the equivalent of buying up the clearance rack for them (recession). They buy businesses, real-estate, homes during this time and eat the cost of investment with ease as they wait for the next boom and repeat the cycle. This is is a chief reason why economic inequality has worsened over decades. In this game there simply will never be enough houses built to meet the demand. Realtor have the biggest lobbyists/unions in the nations; the home-owner/renter have jack-shit.
Could they not buffer or fuse between the MOSFET and CPU? Or is that something that would cause issues?
Hi
i know i can pay for the monthly support but i have a quick question
ppbus_g3h is shorted to ground, when i go between ppbus_g3h and ppvcore i get 0.62ohm an im guessing that means 12v went to cpu so its over
25:19 shorting the 2 components to the left
❤️❤️❤️
Oh damn I missed the good old PP bus.
The good old ppbus g 3 hot 😂😍
Deja vu? Thought I was watching the same video again. You didnt learn your lesson, twice in a row, Louis.
22:08 I'm watching for chat. It improves my English. I think. XD By the way, I had repaired my liquid contact 2011 macbook air myself.
You think San Diego is bad, take a short drive north to La Jolla... THAT'S insane real estate there.
Sir A1398 very slow and fan spine noise how to solve pls suggest sir
Do you want to see what expensive real estate looks like? Come to Dublin. It will blow your mind.
I'm going to take this nugget of checking if the CPU or GPU is dead before debugging my A1707 with PP3V3_G3H at 1.8Ohm and 0.033V. Unplugging peripherals causes the GPU chip to get extremely hot and it takes 20V. When I plug everything in, I get 5V and the GPU does not get hot. Since I suspect a dead GPU, I guess I can take the heatsink off and see if it's actually the GPU or maybe a mosfet that's getting hot. I also remember this video saying something about checking resistance to a CPU pin, but I can't find that part of the video again. If only this was well-documented somewhere!
You're thinking of me saying to check resistance to ground on the 32 kHz rtc clock pin of an mcp89 to see if it's dead.
@@rossmanngroup Thank you! Very helpful.
If you want an ass kicking, don't do it your self FIRST. I'm sure someone will do it...good work Luis (anyway) !
Any laptop recommendations by lenovo in 2021?
Sir can you please help me with my MacBook probA2159 2019 Touch Bar
The battery cannot be read by the smc and so the laptop only works with the charger. The diagnostics show PPT001 and PFM006 error codes.
There is some problem with my SMC or any IC around the SMC
How to solve Backlight issue sir
Have you looked into the Raleigh area? UNC, NC State, and Duke. Plus all the businesses in the research triangle. All while being MUCH more affordable than NYC or CA housing.
Would also open up the door for Gamer Jesus crossovers lol.
I heard that area is really expensive for housing due to the schooling demand.
Louis, I added this to the wiki on two of the A1398 sections under the existing PPBUS_G3H short sections. In future please try to be a bit more descriptive with the motherboard model and Macbook model & year because the A1398 spans several years. I don't own any Apple product and have zero interest in anything Apple so you need to be more specific about the details so it can be added to the correct place.
Will do sir. My apologies, and thank you for your contribution.
you'll have tons of customers in cali tho, and not many in comparison in OK. You could even stay away from the big cities where housing is cheaper but there would still be a ton of customers
Move to FL or TX.
Anyone else noticed that solder ball at the corner of the chip below the fuses? ^^
friend, whats the wiky repair site?
23:30 one more time and you might land an indorsment 💀, would you take the gig?
Maybe it cracked as you were pumping it with electricity?
What you really want to do is move to CA in 1966 and buy your first house in 1974. That turns out to work really well.
Every house in my city, even the cheap ones are almost $1 million. This is the most unaffordable cities in my country
What is Apple trying to protect with fuses? If a fuse blows you're supposed to trash the computer, no?
They are not trying to protect anything. Apple fuses never blow ;-)
If you had taken the cover off and seen the cracked cap and replaced it, it wouldn't have been the 'teaching moment' it turned out to be.
22:22 Why? Your brutal honesty - knowing whats possible - to become enraged with the wasteful tech industry.... Kinda infotainment :D
I saw the title and said toyself "no! Not ppbus_g3hot!"
The Bus is Cold
Ciao, per favore puoi mettere i sottotitoli in italiano sarebbe interessante. Grazie ciao.
22:06 That is not a Louis certified small amount of flux. What happened to you man?
He finally learned that SMD flux is expensive and using a lot makes clean-up more work too.....
You always have at least a default time line, can't move after you're dead.
Hey Louis, I just uploaded my second ever TH-cam video. Exactly why apple iPhone suck.
I pulled every screw out of a broken IPhone 6S. And laid out all 49 screws I pulled from an A1633 frame.
This short video was all shot on my Galaxy S5 I swapped my original main board into all new parts to rebuild my phone with a PH000 screw driver. Anyone every wonder why Apple phones are pita to work on.
TH-cam says this was uploaded 1 minute ago, however the first comment was posted 23 hours ago!!!
he sets them as unlisted before public so if you find the URL you can watch it after the encoding is done, lol
lol surprise, Uncle Joe hasn't done squat
Been wondering: Why is it, in American English, is the L in solder not pronounced?
Edit: Btw have you ever been to an optometrist?
My fear is that changing state nukes your walk-in customers
ever do your taxes and think, what the hell did i spend all that money on? i think this is going to be one of those years for me.
also i bought the new ipad mini. dont hate me too much, its bad for you.
if you want to get away from the 800k middle class house, you have to get out of the city. which means things wont be bike distance away. sadly the only real way to solve that problem.
you have to be in the bad areas for prices to come down in any city, go to suburbs and value goes up but prices dont go down much (things get bigger but not particularly cheaper, and finding the small places becomes near impossible)
where i intend to live is going to be hours from a city, but a few minutes drive from town. i travel for a living, so where i live means nothing for my job. i mostly look for places based on logistics and values, with weather being a close 3rd (love the weather in georgia, florida and gulf coast texas dont have seasons)
sadly louis has no real option to do things my way. either way i wish the best. if you even read this
Executive orders are laws. The same way that when the supreme courts decides something its l
Hey have you got a vid on how you connected the charger to the desk power supply to see the amp draw?
Found the video now th-cam.com/video/B3w8nwyrdYw/w-d-xo.html if anyone is interested
You just need to buy an adjustable bench power supply and it shows the current draw on a small LCD screen on the PSU. For laptops that use a USB charger, plug in a USB amp meter then connect that to the PSU and the amp meter will show the current draw. There are hundreds of videos showing the small amp meter being used, just go back and watch some of the repair vids on this channel.
@@johnbos4637 I have a bench power supply, But how do you connect it to the Mac lead to the psu? Have I got to cut the cable?
@@thetechshack1031 yes, cut the cable and re-wire it. You should buy a spare cable and cut that one. Don't cut up the original cable obviously ;-)
5 eyes. If America can't spy on it citizens. Let other countries do it for you. Technically not unconstitutional.
I watch because it is not full of shit and rings to thoughts i have as well..
time for reading glasses.
Louis come 2 Greece much better than New York and califa better housing and food the only thing which it sucks is the politics just playing bro
How does this have 69 views with 184 likes? Get it together yt
Still 69 views. Coincidence? Think not.
69 views. nice
Saw this at 69 views, nice…
69 views nice
Do you want likes from people who don't care about these videos? or does that disrupt data collection?
What is this crap on my NYC realty/ebiking/government bashing/clinton kicking assin channel 😂
Can you stop posting nerdy computer videos on your real estate channel? Maybe make a second channel for this computer stuff?
In other words Biden did nothing.
Hey Louis most homeless are only looking for one thing and that is there next hit.
Ok
I really want to unsubscribe from you channel ever since ur need to bring up right to repair over Afghanistan, I honestly dont expect much from people. but you disappointed me
