man i love LOOOVE how Italian he is haha
You're welcome 😊.. your an excellent instructor for board repair and modern hardware repair an refurbish after spending your money on a product it's no body's business what you do with your poession other than you.. you should be allowed to repair rebuild and refurbish anything you possess possession is 9 tenths of the law... I repair refurbish certain game consoles and computers of sentimental meaning to me... I only mod consoles that are about to go out of production.. and use to download the library after production and publishing has ceased...
Explanation from Luis Rossman about how to read schematics:
"So this is a mouse, then we open pdf file, then we will see black lines, titles, rectangular shapes..This is a schematics".
Found your channel just a few days ago and i can't stop watching your videos and i have learned so much in so little time, just want to thank you for doing these videos and praise be the genius that is Louis Rossman.
Man. I just found out your 5 years old videos are amazing place to start and to learn from. Thanks!
I know this is an old video so you might not see this comment, but...
Holy shit!! I've been following the playlist for the basics and I'm still in awe at how after running through the previous videos and despite how fast pased this explanation is, I was able to keep up.
You have an amazing talent for getting this shit across a thick skull like mine!
Seriously, thank you!
great vid bro! i have watched about 4 of your vids so far...and they helped me fix a "no post" problem with my laptop. you now have a fan in San Antonio Tx.Lol! keep doing yo thang man! and thanks!
Doesn't matter how many videos I watch of yours. I love coming back to them all, so much more educational than things I learned in school. Make far more sense and relaxing to listen to
i looked this up because i like your tutorials thank you, Rossman.
Haven't done this shit since high school, but watching your videos makes me want to get back into it.
The nut in my head is actually starting to grow or something, thanks!
Finally someone who explains what I was looking for 👌🏻😎 great video thankyou
quick question- when you applied the probe in DC voltage on the multimeter it gave like 12.44 volts and counting like you said but when you did the diode mode it said .44 volts so how do you know the vtop from that .44v I did not understand I kinda lost you there. Do you have to have a good board to compare that diode reading to?
Thanks
Excellent video series! Unfortunately I was only now able to complete watching it. Keep up the great work man!
+BlackHoodProductions Thank you!
This videos are awesome! Thanks for the upload
You my friend, are great. First time stumbling across you.
could you please tell me what are TP5, Tp14 etc written on the laptop motherboard schematics, are those test points to check the particular IC.
what program do you use to open the board view schismatics ive tried 4 all cant ,KiCad, EAGLE, Altium Designer i cant remember the other but no luck ive tried file from 3 different websites some results
yeah we all have things we're expert on, the trick is to teach these things to other people without being condescending
could any one tell me about the purpose of these numbers on figures of schematic lines example on min2.42 showing numbers on one pin . waiting for any one response thanks.
Where is the love icon for this whole series? Forget thumbs up. I've been piddling with electronics repair, self taught, for years and watched probably hundreds of vids to decipher anything that would get to the essence of electronics repair. I picked up a little bit here and there watching hundreds of hours of videos and reading but that's about it. This series is what I wanted. When I finally heard you mention it in one of your videos thankfully, I immediately clicked the playlist and started watching. Unbelievably succinct. Alleviating the rabbit trails that have nothing to do with actual repair was the red pill I have been searching for . You deserve a medal. Thank you Louis. My next step will be finding schematics for Paul's Board View software and learning the ins-and-outs of that and whether it will be beneficial for me. You seem to have a passion for imparting truth, not just with regard to electronics, that is surely unrelated to mere monetization. Having said that, I will definitely be contributing monetarily with heartfelt thanks. I'm going to place this comment on several of the videos in this playlist because I believe that there are many people like me who need this information presented in this fashion and would hate for someone to miss it. Bless you Louis!
Louis, I hope you can help me. I have a three year old Overpowered OP-LP3 Laptop. Recently the glue holding the display on failed and the display tilted down applying pressure to the connector. Not wanting to work on it myself I brought it to a shop that reinserted the connector but the display would not light up. The repairman opened up the computer and found burnt components on the motherboard. Problem is we can't find a schematic for this machine in order to identify the failed parts. Do you have any idea with to find a schematic for this Overpowered OP-LP3 Laptop? Any advise would be greatly appreciated. It's a beautiful machine and I really need to get it working. Thank you in advance.
I like the way u say things. That's nothing but real talk bro 😂 great videos 💯💯👌
Where do you get ur Files for Openboard ? Is there a forum? Or jjust google the board and be lucky?
Is the MCP chip similar to KCB/EC chip from other non-Apple laptops?
Question:
So let's say if I would aks a company for schematics of one of their products that I bought, so as to learn how it works.
This is bad or agains the law?
I don't understand what you explained about schematics. Please let me know.
I I didn't know if you took outside work in or you just dealt with local repairs but I have an 08 Nissan Frontier ECU that I believe is fried something wrong with it how much would you charge to look at it if I was to have it shipped to you
Hello Sir, my acer nitro 5 AN515-55 is not charging anymore. I can repair it myself but I need a schematic. Can you please tell me where can I download the schematic from?
is there another version of video which is not overlapped your body and bench view ?
where do u get schemes with voltage that document or what?
My goal is to identify the functions of the devices in a given circuit diagram?
Or spoken more general.
How can I lean this general skill?
When do I see a random circuit diagram that I can recognize the devices and their functions?
What is the best strategy to acquire this skill?
Do you know good information recourses specially designated to acquire this skill?
I do not want to handcraft things on my own and I do not want to study at a university to acquire a bachelor's degree in electrotechnology.
I just want to be able to read more or less the circuit diagram.
Thank you in advance
I like this guy
So for board view you need to get "Test link drawing program" and get some file to load in? If I get a PDF with schematics it is not enough right? I need some another file with boardview with some extension?? what is the extension of board views?
I will reply to my own stupid question :) ua-cam.com/video/1Pi5RGC-rJw/v-deo.html
Just standard *.brd files are those containing board views... nice
Thank you Louis for great vieos, I am going to try to fix a laptop :) And you made me confident doing it... lets see if I can...
At last...a man with brains. Thanks for a very inspiring video.
Thank you bro
Who i can find shematic diagrams?
Fawwken hell m8. Your videos are my crash course intro. Spot on
I have question about a schematic I'm trying to understand. When I look at the logic board of a macbook air there are some spots where there aren't any resistors or capacitors soldered, but when I look at the board view and check the schematic there is a suppose to be a resistor or cap there. This is on several spots and I don't think anyone has worked on this board before. The question is, how much can I thrust a schematic? Because on this particular one there are lines like this "Intel investigating whether RC is sufficient", this looks like this is not the final version of this particular schematic.
Your thoughts on this please.
are you sure you have the right one. and are you sure you are reading it right. it's normal to have points on a motherboard where you'd think a component should be. but then there is nothing there.
from where to find schematic
It would be great if you can show the full schematic diagram as it was blocked by your video.
Very nice video. Thanks. A question for you: One of the problems I have reading schematics is that I sometimes can't see clearly what is coming in to a component/circuit/chip etc. and what is going out. Some lines will have an equals sign, some will have an 'In' or 'Out' label and some will have nothing. Any ideas to help clear this up? Thanks.
How can now get them
You are not a teacher but you are an entertainer for youtube
where do you get thos schematics? I saw you using like 2 diferent programs can you explain?
If you ever get Right to Repair in the US, hopefully you can get the manufacturers to publish the schematics, too. The current state where you have to hunt for schematics from less or more illegal sources is really fucked up.
Think your videos rock. Learning a lot. I run a recycling service and have loads of laptops that I usually have to junk out. Can do some basic repairs like usb ports, dc jacks ..etc light stuff. Just order the microscope you suggested (the cheap one) and am going to try to learn some new skills. Thanks for the videos. Not sure who to message you off the public channel but was kinda wanting to get some pricing. Mostly for the mac stuff, not sure the other stuff has enough resale value to justify the cost of sending the boards out for repair. will try to figure out how to private message you. but back to me working on them, have a couple quick question. where do you get the schematics and eagle viewer files for the boards. also do you stock all the parts (seem like it would be costly to stock most of it) order as you go.
Thanks so much, these videos are awsome.
You claim to watch his videos, and yet you ask where does he get his schematics from, watch again and pause the video when he as a schematic on screen and you will see the watermark with the name on it.
Do you know why iPhone schematics don't seem as detailed as the laptops? For instance there's no page showing how main power gets distributed in sequence
+mrsemifixit Apple stopped doing that for laptops as well in late 2013. If you can look at new laptop schematics for Apple motherboards, you will see no such block diagram
Louis Rossmann Wonder why they stopped. Their schematics can be confusing when trying to trace the sequence of voltages created. Any tips on that?
VDISP_P_OUT does this line is for graphics
Wait there is a schematic reader plug-in for the PDF reader
And here I am using my brain
is there a book you can read that will explain how to interpret laptop schematics?
+OnlineBackupServices No. Laptops are just like anything else, circuits comprised of power circuits, data lines, etc. Watch the channel and it will all make sense with time.
Jesus... it's like he's deciphering ancient hieroglyphics
you left out the zener diode
I dont know why this stuff is not deliver in my electrical engineer program which is quite strange. They just dump on the math into our face
for what obvious reasons aren't you supposed to sell a schematic? because it's basicly a blueprint and you can "make" your own brand name product? or because we are not supposed to fix them ourselves?aren't repair shops supposed to be able to get their hands on schematics in a legal way?i'm not asking how to get a schematic btw. i already found one for my board and a boardvieuw.completely free. but the question is. why do i have to obtain it through such obscure forums and such. why doesn't hp (in my case it's an hp) just sell them to registered repair buisnesses.
This would be much better if we can see the whole block diagram.
How to download free laptop board viewer please tell me sir
Download Open board view. Go to pldaniels.com/, click the open board view icon, and download the relevant release. Schematics you can get by googling around.
I understood the basic components and semiconductors... I refurbished my own neogeo MVS hardware and had 13 or 14 pages of wtf is this and how do I test it... it's also when I developed chronic migraine headache syndrome from bashing my head through an old-fashioned plaster wall pre sheet rock aka dry wall... lucky the NeoGeo arcade community is extremely friendly to those in need of help and was mentored me.. if I had a quarter on me I would spend it on the neogeo machine.. and remain standing there semitranced for 30 to 45 minutes... then take a long overdue whiz... I was never able to afford the neo get AES home console at $650.00usd.. and game cartridges at +$300.00usd each granted the cd console was half the price but a 1x or 2x cd-rom drive took 30 to 45 minutes for a game to load...
I had anti violence anti blood and gore parents searching my floppy discs and hdd for doom wolfenstine3d .. they even think the classic dos shareware game Scorched Earth was too violent... because your trying to nuke an enemy trying to nuke you.. good old 80's cold War game addictive game too..
You mentioned "for very obvious reasons i cannot sell you scrematics / tell you where I get them"
These "obvious reasons" arent so obvious to me, are they suppozed to be private?
+BevcaN izBevk First off, Schematics. Second, If he gave you schematics, he might lose business. If he helps you, he gains nothing. If he doesn't, he loses nothing. If he does, he might lose business.
+BevcaN izBevk It's really simple, copyrights! Don't you think is weird that you can only find them on russian sites, or some other foreign country.
It literally says on the screen any time he has a schematic open where he got it from lol.
Hey Louis , is this some show off or are you trying to help ? I see many questions unanswered. Actually you answered zero questions here.
Going into this with a smidgen of knowledge will typically help. If you just jump to this instantly and expect to be a genius, you're definitely going to find more questions than answers.
Ya he doesn't really help a lot. I know he is trying to be kinda smart and make a point, but no need to be so condescending IMO. No doubt a clever guy and I do very much appreciate all he shares though, stand up guy either way.
Louis shared this training manual a few years back.
docs.google.com/presentation/d/1PkeO_lC5WTPScSV3ZzEEjVuDWeQtL2eHK6jEcf7axA0/preview?slide=id.g2a3d5327f3_39_0
Thought I was the only one .
Love all your videos with 1 acception, your tone is a bit condescending .... as if we're suppose to know things that you explain, If i knew it i wouldn't watch how you do things....however, i try to ignore the "insulting manner" and muddle through. May want to take a lesson from Jessa....:) But i get it, it's just who you are, fast explainer with little patience for newbs
im so bad at reading so i prefer looking at canmponents right in the motherboard instead of a schematics as much as possible
Sorry that question was for the data line video
Dude I'm Self Taught Schematics for Electronics Electrical and Circuit Design
Helps to reduce ignorance hahahah
Louis "PPBUS" Rossman
Another one of those guys.🤔😂
Anybody here thinking about computing voltage and current to every point? Or I'm insane?
In other words, you "read" a schematic the same way you "read" any other type of reference document. It's not meant to be read like a book, it's meant to be referred to when you have a specific question about the device or assembly documented.
Can you um... tell me how to know everything? ;)
Trying to follow along is hard to do with your noggin in da way.
why are you talking at lightning speed i dont like when you do that to amatuers. sorry but u get me upset louis
Glenn Ferris This comment actually made me laugh €_€
hahaha Louis was an upcoming rapper in Eminem group
He seems smart but unfortunately, the way he is teaching, (teaching method) is not the ideal for someone who dont know yet what schematics is, is not ideal for someone who wants to learn and who is in the beginning phase, it is ideal for someone who is at his level...🤦🏾♂️😡, he seems like he wants to show how much he knows instead of teaching, but anyway,l..
be good if you didn't carry on
Well, you became a bit rough after some time xd
First!
Obnoxious. If only we were all as smart as you.
i'm not smart nor do i claim to be
This dork is just here flexing lol. Not a teacher at all
spoken like someone who doesn't teach
