Board Repair Basics #3 - Buck Converters 

God bless this guy, he's literally the only one who can explain motherboard repair on youtube. No one else is fit for the job.

i literally feel like i own you money now // best explanation ever man !!

Please continue .. this was the best explanation i have ever seen. Thanks alot man

Glad to see that someone is taking the initiative to teach board repair systematically free of cost......thanks a lot

I have never got any body to explain it like you do. Thank you for your generosity. God bless you abundantly, Engineer.

I dont care if this is late. This dude is awesome. Very well explained and detailed.

Yeah adam is about the best teacher on Utube by far, his voice is so clear easy to understand for me, I am 70. All the best from Ireland,

Amazing. In 2 years I wasnt able find anyone explaining so clearly electronics repair as you did. Thanks a lot.

The amount of epiphanies I had in this video are striking. Everything started coming together, thank you so much!!!!

Wow, the Buck converter: never heard it explained better.... Thanks Adam, much better than the other arrogant RU-vid posters.

Dear author. Over the past 2 years I have searched a lot of tutorials on this matter and each time I gave up as the teachers seem to lack any teaching skills. People in this field suffer a collective lack of empathy. I'm now 3 videos deep in your tutorial and I already know that I've finally found a guru. Please let me know how I can donate.

You are a genius man thanks for educating us across the World

I've been trying so hard and searching for videos on RU-vid for freaking years to learn this type of thing and I haven't really had any luck anywhere because nearly every video confuses me in some way or another. I've learned more in this sub 18min video than I have in many many hours of other videos on RU-vid. You have no idea how much I appreciate you doing this series. Thank you so much.

I have literally graduated from electronics and networking LONG AGO, about 2004, but i never heard better, explanation on almost anything you ever bring on as a topic. You're pretty underrated channel my man. Like what the heck. I know it looks stupid, that i have no better work like looking on board repair videos friday evening, but i just found your channel few days ago, and as i am working as self employed tech support/computer repair shop, man, you rocks.

Excellent presentation !

Graham would have to be one of the best teachers i have come across on RU-vid. I started working as a tech at my local IT shop and his videos have given me a lot of confidence and understanding when it comes to troubleshooting hardware issues. I definitely recommend watching all videos in this playlist as every video is full of great tips. Thanks Graham!

You have the best tutorials on RU-vid about this stuff. It's a shame you don't have a million subs cuz you deserve it!

I cannot thank you enough, your tutorials are a literal diamond mine here on RU-vid. I have learned so much and been able to almost immediately replicate the teachings because your explanations are so clear + consise. Thank you again!

You explain this better than Louis Rossman!

I'm totally new to electronics yet I finally understand why coils and capacitors are used , This video is what I was looking for since a long time . THANK YOU !

God bless this guy, explanation is clear as water. And he doesn't have an awful Indian accent that you can't fully understand.

He is genius guy. Very humble looking guy. Good on you. Those who know the knowledge they don't want to explorer to others because they want to take their skill in the hell section.

Hi mate, you alright? How can I get you a coffee? You're helping me a lot into my attempt to build a career out of this. You can't believe how useful everything you explain is.

I like this ground-level approach, others act more like magicians, where we see something done, but do not quite understand the underlying logic.

love the explanation. very thorough translation from theory to practical love this channel

Honestly you are a legend.. you have contributed so much by these Series....God Bless you Man👏🏼👏🏼👏🏼

Best explanation of a buck convertor I've ever heard !

Reading other lessons on buck converters, I understood the premise and the way transistors work, but this video allowed the pieces to click when you explained how the varying voltage ratios allowed for the coil to output a different A/C current into the capacitor which straightened it out, also help me get a better understanding when you mentioned how there was a drain for the excess from the coil.

You Nailed the Duty Cycle explaination...Awesome...

Excellent instruction! You're a natural at teaching. Bravo! 👏🏻

You are simply awesome man. I would pay for your course if you should do any. I've searched the internet far and wide for stuff like this and NEVER found any. Thanks a million!

this is a good video to give a second watch because i was initially lost but i like how at the end you came back full circle to the actual board and showed these components having been sitting there the whole time. I literally know nothing about this stuff so I thank you for the videos.

Great explanations! I've learned bits and pieces from other channels but your explanation that pulls together the theory, schematic and physical view on the board, along with the method to get from one to the other via naming is by far the clearest I've seen so far.

Wow , I’ve watched a TON of electronic courses and this by far, is some of the best explanations I’ve ever seen !

You explain electrical concepts incredibly well-much better than most other videos on RU-vid. Subscribed!

You are a real teacher, a repair master of the electronics world. Thank you very much! I am your student, actually I speak Chinese.謝謝你！😀

To the point description of mother board .excellent n clear voice. thanks for video

I FINALLY understand voltage rails, Thank you! Here's a sub!

Everytime he says PPBUS_G3H I hear Louis' voice in my head ... (Louis Rossmann)

Very well explained.It was my first time on your channel and certainly loved it.Please keep up with your good work adam.

Amazing tutorial and easy to understand. Best explanation on youtube

thanks for a great use of boardview, DMM, active logicboard, & explaining this!

I hope you get more subscribers man , as a graduate electronics engineer you actually did very well in linking theory with practical design aspects of PCB design !!!

Graham thank you so much for the great explanation and structure of your videos. I call this generosity!

you are very talented and not selfish to keeping this knowledge to yourself!

Although my English is not at such a stage that I understand everything you say, I must say that your work is perfect and I feel unfortunate that I was a little late to discover you. Congratulation and keep on

You are a diamond on this webside

Awesome thanks! I learned more in 17 min than a year at my school. haha not to old to learn cheers!

Fantastic. Thank you. Very well explained.

You sir are awesome 🤟🤟 after watching these a few times to make sure I got it right in my head ima apply what I've learned to track down issue with a recent MOBO that was brought to me that fried my only FX CPU when I was testing to see if CPU or MOBO....
