Question sir. I'm a long time fan. . . Macbook pro mid 2012 white screen on start up. I thought it was the HD cable. . . Changed it. Still nothing. Next I changed the drive. Still not finding a drive. When I attempted to restore mac os I can't find a drive to download it onto. What is the issue?
hello friend can you enable the language in this video please
this is what I call real Pro, with proper knowledge, skill and of course the right tools. great work!
For the dude going in on the criticisms while blocking anyone from replying to his comments...
1) Miles of wire I have that does the job > wire I have to go out and buy and wait for.
2) "Proper" tweezers? As in.. it is improper to use one's preference? Angled tweezers are a pain in the ass. I have at least five pairs of them here, not as sturdy when I want to grab and shove something where I want it as the straight ones.
3) I could have used a chiseled tip, but didn't feel like changing the tip.
This entire job is meant to take about 1 minute. From replacing resistors, capacitors, chip, and running jumper wire. It was going to be miserable regardless of the tip I chose to use, since I can't see or look at what I am doing anyway. I realized this going in, but kept the camera in so one could see troubleshooting from beginning to end. If beating your chest on all the crap you would have done differently makes you feel better, feel free to do so, but do realize how lame this is when the entire reason this job was a nightmare was so that I could post it for others to watch and learn something about motherboard fault troubleshooting. Really, ask yourself how you would do soldering looking up into a TV with half a second of input lag on its HDMI port..
+Louis Rossmann Theres always trolls "keyboard warriors" ignore them i personaly thank you for helping me learn and be better at my job you use what you use and do it how you have learned to do it your not a nob they are they have learned to be nobs lol take care brother
***** Same
+Louis Rossmann hi my names bracken harris and i want to repair stuff as my job i am 15 years old and was wondering if you can give me some tips my email is brackenharris124@gmail.com thank you
+Lights-Out Gaming lol i can see why louis gets pissed with commenters. tips = there are thousands of videos on here you can watch and learn and you want personal tips via email?
OnlineBackupServices You get it.
Honestly, the beginning part where you go through testing the power lines, but actually showing how to do it is super helpful for the new guy. I feel like a lot of that gets quickly mentioned but never fully explained and that's why people have a hard time getting started. It's embarrassing to ask where the red probe goes when you know nothing, but putting in those beginning basic steps are so much more helpful than I think you think they are. I don't know maybe that's just me, I don't usually comment anyway, but great video.
Justin Millman Thank you!
Justin Millman The problem with most teachers is they have forgotten what it is like to be clueless. As a result, they leave out all the parts they think you should already know.
I hear that, you do something a 1000 times, and you forget that even the easy parts weren't common sense at one point.
I think the same is true of teaching in elementary school level, and with parenting. It is easy for adults to forget what it was like to be a kid, the same way it is easy for a professor to forget how difficult it was to learn the first time around.
Your a good human. I saved 2 mbp [2012 and 2010] thanks to your videos, watching until it sank in. I got my local iphone head to replace the bad cap. He didn't charge any thing, talked about the same tuff you do. He got raided by tim cops next day..! He's a follower of your RTR efforts, as are many in Ireland. Wise man.
Hi there from South Africa , I just want to say thank you for at least doing repair videos and I appreciat every second i can learn something from you, thanks from mark
Hey Louis...great job all things considered. Want to let you know how greatly appreciative I am that you take the time to not only help us fix our own devices, you try to make us think too. Please keep on truckin.
Never seen anything like this, but damn dude. This is some high quality content!
+Elias Vågan Thank you!
Before I whent and purchased my self a AMSCOPE I got a USB Microscope camera off of amazon, and i have had a hell of a time trying to work like that. After seeing this im a lot more confident if i get a proper scope I will be able to work much more efficently.
Thanks Louis, I've been a assembly tech for about 5 years now, and am trying to get into board repair, your videos have been an excellent help !
Hi Louis, I've been watching your videos lately because my old macbook pro was damaged by liquid a couple of months ago. I ended buying new macbook pro. But after watching your videos and trying some of your diagnostic methods. I found that the only thing that was broken with my old MP is the display!! I fixed it. Now I have two Macbook Pros. Cool in a way but, also expensive.
pro audio tech for the last 15 years,( I'm still learning), your method of circuit troubleshooting is awesome!!!, I worked for a recycling company tried to get them to fix a few things at component level (because I can do that) and found they were more interested in pulling heat sinks for the copper, that companies no longer exists
For real though, this these videos literally blew my wig off. I had no idea these resources were available to fix your computer. You literally saved me $600
Love you're awesome videos Louis... Please Please Please keep up the good work.
Ant W Thank you!
your effort on the video talks for itself. nothing else matters. thanks mate keep it up. i want to have the same set up in my room :D
Your videos are f****** amazing, I love this channel. I can see this channel having tons of subscribers in the future.
+norkator Thank you!
Great guy ! I start watching all your videos like 15days ago and i just can say keep going with videos!
This was the first video of yours that I have seen. I enjoyed it thoroughly! I loved how you got right in there to show the work being done albeit your work around that I know can be infuriating. AWESOME JOB bro!
Entertaining ! Thank's for your video channel, it's my new favourite and helping me learn what has always been beyond my grasp.
I am glad I found your channel. Thank you for the work that you do.
Just want to send you some Positive Feedback of ALL work! You are AMAZING and LOVE your witty sense of humor/comments. God Bless
Man you crack me up. Love to see you do this. I did this type of work 30 years ago when things were much larger. And just started to do it again. What kind of microscope do you use? As there is no way to do this anymore with a bare eye.
Thanks and keep up the videos
You kick ass
triblackcorvette omano 1030-jw11
Surgeon, this is what I can say about you. Fantastic job, you should be a mentor.
Dude - YOU "HAVE NO IDEA" how much ALL OF US appreciate your persistent integrity to FIGURE out what "I" just take for granted. I've gotta contact you - My 2007 MBP 17" is "DEAD" - Can I get the COntact info ??
+zedieliam is it is from 2007, that is pretty much how it will stay. Not much I can do with machines that old
Hello sir
Louis your videos are really great and I see that you give your maximum for explaining thinks and I appreciate that really, a small tip will be for example as you explain something in the scheme with the mouse I cannot see the mouse for what you talk, so if it is possible for making the mouse visible that would be great, but if not of course there is no problem because so and so we profit from you a lot.
Thanks again
+Edon Demiri Thank you! I've begun doing this in new videos.
***** Tried that, it didn't go well.
Very intricate work you're doing..glad I found your channel
hey i like your videos and who cares about the setup, ain't nobody got time for that. clutter desk shows the man really is an expert and genuinely show the business. thank you for making these tutorial videos. I don't own a mac but i enjoy watching for the sake of electronics information. this is much fun then my electronics lecture
These videos are amazing. So happy I discovered your channel!
The Law Thank you for the kind words!
Eyepiece problems or not, your content slays. Thank Louis!
Hey Luis maybe a bit late but Since I dabbed with Camera repairs.. Those lenses are not fixed, most of those cameras have a screw on type lens which you can turn in and out to change focus range. Take the camera appart and check the lens mount screw Assembly to see if you can pull in out out to match the Microscope. You can also build a DIY riser for the Camera on the Microscope . Good luck I have fixed many Go Pro's due to the lens being on too tight from factory.
Thank you for the guide. I solved my macbook problem, now it works again !!!
Love your videos! Don’t let them get to you. Thanks for the info!!
I appreciate you trying your best with your given situation at the time to just make a great FREEE fucking video for us plebs. Love your videos! Thanks Again
Hi Louis! Nice video, well done. I am not technical or have any of your equipment, but I enjoyed your video and teaching. I do have a now broken logic board A1398 on my Late 2013 MacBook Pro Retina. I see the green light, but it wont power up. I was wondering if you would be able to repair it, and what the cost may be. thanks!
Hi Louis, I like your repairing stuff. you have a great skill and knowledge about this sort of stuff. I work in a place and repairs Mac. I am learning and working. One of the regular fault I see in MacBook Pro or Air is no power. Few of them I can fix if its normal. But if its related to logic board I cannot fix it. Because I don't have enough knowledge about logic board repairing. Can you please help me out?
Awesome information. .. channel is best on UA-cam.. thank you for sharing. Recommend a dual monitor setup.
Louis, you are the MAN. I got started on your video about how reballing is bullshit. I would really like to start screwing around with type of stuff. I have a 2010 macbook pro with good power to the board but now need to start the tracing game. Do you already have a list of equipment that you use? If not , I would love to hear the details on your tools.
I don’t even watch these to learn anymore 😂😂 the learning is just a bonus now
Hello Louis, I happen to run across this video searching for why the Macbook Pro wouldn't turn on. On another UA-cam channel someone led to using jumpers across the power pads. That didn't work. After seeing your video I checked the power on the fuses with my volt-meter on the logic board. No power across the fuses, but I do have power on the board connected to the power supply. My guess is that one of the fuses is toasted unless there's a regulator IC chip that's causing the issues?
Microelectronics...man you need a needlepoint soldering iron!
Thanks again for your experience and knowledge
hey louis i watch every single video of yours and a very big fan of your work.... i recently 11 months ago purchased a 13" macbook pro...now after 11 months i have some problems when i visited the service centre they said that it had mlb problem ..also trackpad problem and display issue i just want to know if i have the right to ask them to replace my whole macbook or just replace all the necessary parts that might as well be refurbished...... Hope for your reply ASAP need help
I very much enjoy the sarcastic verbiage...
10:10 "Aaaand let's start...... So I got my fume extractor turned on here so that... I don't DIE"
HAHAHAHAHA
Thanks Man, don't know any better way to say this but your videos haves saved me a lot of time. wish a can have the class but I'm in Ghana. Keep being Awesome. love the sarcasm too.
Hey I have a iMac 5K Late 2014 and it was not starting up. I gave it to Apple service center and they say that my Power supply and Mother Board is faulty and I will have to pay $1000 to get it repaired. Now since its already 5 year old I don't wanna spend $1000 on it now. Can I get my faulty Motherboard and Power supply repaired?
Thanks in advance :)
Sure
I like how this dood is so technical and knows his stuff but isn't afraid to talk like a sailor.
+Jude Wynn Thanks for watching! I haven't met a sailor yet in my lifetime but people keep telling me they curse less than I do... ?
Your videos rock! Love em!
You should create a course or something I would definitely buy it!
Quick question what software were you using for the logic board schematics?
Thanks
This dude is a walking genius
Loved the video Louis, found your channel after doing a PS3 reflow and found your discussion about why reflowing / reballing is shit and doesn't work. I didn't understand about how heating the chip fixes the problem, but I found some articles relating to Mobile Ions which backs up your theory.
Your work and discussion is very clued up. Watched this video all the way through, gave me some nice ideas and understanding on how you do things and troubleshooting procedures you used. Glad you decided to show the video rather than use the microscope so understand your frustration.
Couple of things
1) The schematic program you use that you hate so much. Landrex / Nets, is it any good would you recommend it. Or would using the schematics from PDF's work. Or do you like using them in conjuction with each other
2) You mentioned when checking the schematics that the manufacturers have certain tolerances built in for the rails. Are these tolerances usually discussed within the schematics. Is this just a value you tend to follow from experience (ie within 5-10%) or is it taken from knowledge of the circuits and the resistors/capicitors used.
I loved the video, you have a relaxing personality and it's easy to listen to. I always used to follow EEVBLog and now follow you as I thoroughly enjoy your videos and you're very much a perfectionist with the work you do
Regards :)
Hello, all those real time videos are very interesting. so with the digital microscope you never have a good 3d view, ? I understand that working under flux is then difficult is not it ?
Your videos are quite helpful, some comments are from novice persons that have no or little electronic knowledge & should study a bit.
I am looking for a magnifier lamp for laptop repair. Not too expensive but good for senior eyes. Thanks
You keep really calm, I was getting wound up, just watching you. 😄
Just gained a lot of respect for your line of work. What is the average price for a repair like this?
idk how this dude does it but he's criminal amazing
Overal wery calm and profesional. God work!! Tombs up.
this is what i call a pro. really great video. suscribed
awesome job! I just accidently came across your videos. I am definitely a subscriber. Thanks for all the bullshit you go through to make us these great videos! :)
How did you develop these skills? You're damn good at this.
Thanks for this video! I feel the same way about contractors and repair stores. I'm trying to figure out how to fix an epic fail by Simply Mac (Vanderbilt location). They tore up the logic board in my mother's Macbook Pro. All she wanted was more internal memory. She should have waited to pay them. They did refund her money, but now she's left with a broken Macbook. :( I'll research videos and tutorials like your's before I ever go back to Simply Mac...they Simply Suck!!!
Hey Louis, I have a 27" 2010 iMac that has a bad logic board. Do you have any suggestions for me to fix it? Do you think I should buy a replacement or have it repaired? Thanks for the tutorial, very interesting stuff!
What program are you using to view the schematics and where did you find the schematics? Thx bb
look at the pdf background text in gray, it says it's from a web site, evidently called laptop-schematics.com
Enjoeyd the video enormosly!
Thanks dude!
I love this stuff. Im cracking up because I've been through the same stuff. Bad donor parts. Trace wire bs. Keep it up. Those guys correcting your "mistakes" don't do this shit for a living. They're college graduates living in their parents basement. F them. Hope you're degrees keep you warm at night while we're making money.
Hi,great work, one question. Where do you get the electronic circuit for these motherboards?
Hi i live in the UK and have two alloy macbooks that have stopped working, I have had local PC shop take a look but they had no luck and did not really want to look deeper than the power connection, Could you help if i posted them to you ?
Good video! Keep up the good work! :)
hey dude thanks for all the videos
HI and good day
I try repair a hardware problem of logic board in a A1278 Macbook, where i found diagram picture about situation of components similar to ZWB tool?
BEST REGARDS
Hello by any chance have you got the chance of interesting at fixing MacPro"s power supply or any chance u know who has tried.Thk .
Here's a tip- When the pad is oxidized and the solder won't stick.
You can use rosin flux on dewicking braid and clean the pad to fresh copper. Though @22:17 the pad to the cap shows the visible break in the trace.
OR you can scrape away the enamel from the trace, and jumper with solder. Then with a tooth pic apply a drop of clear or green fingernail polish to cover after the IC is replaced.
The difference between clear flux and rosin flux is the oxidation of the petroleum based flux cleans the solder pads.
I somehow think he knows enough tricks working with these things by now , been doing it something like ten years + , yes you can teach an old dog new tricks but the things you have commented on he has done a thousand times
i like those little cities within the motherboard , i know they are hardware stuff , but a city looks more interesting
Hey Louis!
Why didn't you use a copper tape to connect a chip and resistor?
You used wire... but i think using copper tape might be better than wire at this case.
+woonsik yeo I have wire everywhere and have no copper tape.
+Louis Rossmann Of course using wire is very useful.
It is good to connect to resistors, capacitors and chips has long pin(LVDS Connector). On this video, it is hard to connect to resistor and very short pin of U7200(LCDBKLT, ISL6259). So i suggest using copper plate tape.
damn your sarcasim is sooo damn funny. This is the first video I've seen of yours but if you don't do them all pissed off you should, You should have your own sitcom or be in movies.
At 19:00, rather than using a wire, is it not possible to scrape away some of the insulation on the trace and then solder onto the exposed trace to create a new pad?
Hey Louis! Great Job! Thanks for the precious content, even with the crappy micro setup conditions :D And yeah , the bipping in your head ... it's normal, I also get it! It's the continuity of your brain cells ! God bless that ;) Keep up the good work!
I think you can get them to adjust to each other. you'll figure it out. The romanian over in london with his school, showed how he did it, or rather that he did do it. you may need to change the height of your part from the table. that is too much money to not work.
This shit is sick man, keep it up! Thanks for taking us through how you repair electronics!
+Brannon Wadforth Thanks for watching!
I have talked to 2 technician and both say that logical boards cannot be fixed, rather they should be replaced. I have an issue with on (supposedly) and the price is around US$ 800. So, according to this video, boards can be fixed, correct? Why don't they fix them then?
i have no idea what your doing but your fucking funny and this video was awesome
You fix these? My 2011 MacBook Pro 15” has a bad logic board. Thought it was the battery because it’s run through the battery but I bought a new one and same thing. Took it to computer store and they said it was the logic board. If I mail you my computer can you fix it? Thanks.
It kills me when you used the word Clusterf**k ive started using that at work and my co worker laughs at me. In a good way I learn a lot from him too
so the first step of yours is that you measure the main rails, which is kind of an easy step because they are all listed on one page of the schematic. but with iphone schematics i just had to find out that there is nothing like that page where all the rails are listed. it kind of just starts with the details of each circuit.
am i overseeing something or is troubleshooting not as easy with an iphone as with a macbook?
outstanding. anyway you can record the repair on a macbook I would send in?
I had water damage...i managed to clean all with IsoPrpyl..now I get dim green light..but MB not starting..any suggestion?
Thank you so much for teaching me ......
Dude Iove your videos but I love what you do where you study it?
Following your videos with interest. I have a similar fault but no water damage. I get a green light on charging lead but no power up. Now I'm trying to learn so working my way through the Supply voltages from the schematic and reached the PP5v-S5-LDO. This is fluctuating between 3.9v to 5.v on cap C7273. Is my next stage to check the rails that PP5V-S5_LDO supplies like PP5v_S5_tpad, PP5v_S5_p1v5ddrfet, PP5v_S5_p5vsusfet?
Any help much appreciated
Whats your thoughts on torrented schematics for someone with no budget and starting out? I am just asking for broken macbooks from local classifieds to fix and selling them on ebay (although at the moment Im just giving the macbooks to friends and family for beer money). Schematics I presume are really expensive?
+OnlineBackupServices I don't endorse piracy when there is a legitimate, legal outlet to purchase content or intellectual property in a reasonable fashion.
If I ask Apple to give me a schematic and I offer them $1,000,000, they won't give it to me. So, torrent away.
Hir sir rossmann can you do video how laptop powersequence with schematic explaination tyvm :) have a good day
Nice video man! Shame about that 20% FOV on that microscope! Keep posting!
For one, I like your straightforwardness on the video, and sometimes a laugh my ass off! lol Keep it going!
Louis, would you know the gauge of the jumper wire. I dont have any dead batteries laying around. it looks like something around 30 awg? maybe smaller?
***** NO CLUE! As usual in this industry information, parts, resources are never available. Just use what is in front of you and pray.
Hi Louis. Firstly I just want to say I love your work and thank you for sharing your skills and talent with us.
I have a Macbook Pro 820-2879 which I now have the charging light working (thanks to your video). But it doesn't turn on when I short the board power button - it shows 3v though. On the MCP89MZ chip 2 of the big caps read a short, is that normal ? I've even replacement the chip twice. and even on other boards I have these caps read a short (but old boards turn on then turn off after 3 secs).
+Gurjinder Virdee ohms law will tell you why chip that takes 20 watts on 1v line is not shorted to ground
Thanks for the reply. But I don't see the answer. What's qv got to do with the Power Button Pad on the Mobo? And why does the MCP89MZ have 2 caps showing as being shorted?
+Gurjinder Virdee what line are the caps you think are shorted to ground on?
+Louis Rossmann It's 2 / 4 big caps which are on the MCP89MZ , not on the Mobo. they're showing 0 ohms and my meter is buzzing to tell me they're shorted.
what software are you using? just curious... thank you.

Nice video. I am using my iPhone 7 as a microscope and cast it. It may help
hi, Louis so unfortunately i purchased two macbooks that both need the (U7000) 625 9AHRTZ replaced i am only in $140 AUS on both macbooks can you suggest a cheap but good airflow station and soldering iron that would do the job.
Great video, thank you Louis!
I currently do board repairs with a on screen microscope, but can't stand it anymore. Time for AmScope!!
Very well done THANKS!
