Hello my friend! I want to once again let you know that I and I am sure all the others commenting here really appreciate your SMD power supply videos. Best of all they are in the English language which I do appreciate. There are many excellent videos coming out of India and they are detail like yours and well presented but the problem was most of them was in Hindi. I can attest to the fact after spending hours researching and learning SMD POWER SUPPLIES that the information you present in such an unselfish way is invaluable. I had to make the transition to learning and understanding SMD power supplies back in 2009 when my 26 inch CRT JVC TV started having problems. During that time most of my time had been in linear bulky power supplies until I went to work in 1982 in Aerospace as an NC and CNC technician where extensive training was provided in SMD Power Supplies. Due to the urgency of keeping the equipment up and going most power supply problems resulted in a remove and replace and repair later. I did get involved in some of the bench repair of SMD when conditions allowed but as you know switching power supplies requires a through understanding and dedication as I committed my self to. There is some difference when it comes to industrial SMD power supplies as they are usually built to strict precision and standards. When it came to consumer electronics such as home appliances, TV’s and etc in the present day and time things are still being done the same way but with new improved technology and now I am having to deal with the tiny surface mounted devices and microscopes. I have been involved in Electrical and Electronics from service with the United States Air Force as Computer systems specialist world wide, Power plant technician and operator, and many other disciplines for the past 49 years so I appreciate the excellent information you have provided and so detailed leaving nothing to guess about. Started out when almost everything relied on the old vacuum tubes and now dealing with design work involving Raspberry PI. I am now retired now but still involved in the repair and service helping out who ever I can. Thanks to you my friend you have made me a better technician. Keep up the excellent work as I have watched all your YOU TUBE videos and spreading the word about your amazing channel. Thanks for taking the time to read my commentary but I believe in you and you deserve the recognition.
first of all i have no suitable words to say "THANKS" as a return of your valuable and golden words for appreciating my efforts and considering my work as helpful and informative.
i have my motto to share my practical experience with implementation of theory so that the viewer must get some useful information.
it is your greatness for being in my channel
please accept my best wishes and best regards
Great, informative comment! I love this channel! Some of my favorites include also Mr. Carlson's lab, W2AEW, and homemade102. I always appreciate intelligent videos and reading the great comments!

I have been repairing these power supplies for some time now, but there is always something new to learn. I like the little trick with the resistors to simulate the voltages. Never tried that before! Very informative. Keep up the good work! .اَلسَلامُ عَلَيْكُم وَرَحْمَةُ اَللهِ وَبَرَكاتُهُ

Excellent video I loved the explanation both theoretical and practical. I hope to see more about power supplys on your channel. I practice electronics as a hobby and switching power supplies are the ones I have the most difficulty with. Thanks for sharing.
Mikka Nandri sir🙏🙏🙏
Sir nice
My computer booting continue remedy
if it is rebooting most common issue is operating system. you can re-install windows or you may repair boot system using boot repair disk, if you have
Thank you for your detailed guide about power supply units. I was very less succes rate in powersupplies but I think now I can do better because of your class. Some powersupplies of branded PCs like Dell and IBM will have lots of protection circuit and are far more complicated than this. and the worst thing is we can't get any details about their ICs even if we get details we won't get the replacements for them. What to do at that time, because those PSUs are lot costlier than normal computer SMPS and many time we won't get new PSUs also. We have to throw them only because of SMPS issue.
And also some time we get burnt boards. According to you a normal SMPS with how far burnt is good enough to repair than buying a new one.
In TL494cn ic datasheat there is no mention about voltage pins like you explain. (12v 5v 3.3v) help me to find which pin belongs those voltagers. In my power supply does not turn on when power on. It just try to on and immediately turns off, looks like short circuit, fan try to move. I learn lot of thing from you and other component breack bown i repair them from your knowledge which you share with others. Make more videos to help us all. Thanks your are a genius...
@@HaseebElectronics thank you and I watched it. Could get an idea but still having doubts. I am just douing electric plfor fun and not a career or professional. With you it makes easier...
Thanks Mr. You never disappoint

Hi
Very good video my friend. Thank you
Although I have relatively little experience, I learn a lot from you sir! I have't seen all your videos yet, but one on counterfeit components should be mentioned. Cheap "no name" 85 degree capacitors are the source of many failures. Your notebook in the background say's "It is difficult", but you make it easy! 🙌
best regards and i am thankful for your valuable appreciation.

Hi, please help me with my scenario. I have an atx power supply which was not turning on the computer. I opened it and replace a bulged capacitor (2200uf, 10v) and after that it worked great for two hours. I opened it again and I have tested all components to my knowledge they are good, but the power supply does not work. The first mosfet does not seem to turn on.
do you have 5 volt SB on purple wire?
do you have around 5 volt on green wire?
please reply
Im very glad that you uploaded video in english.and we learned a lot from you.i hope you continue uploading video.thank you.
I have question where dis you connect the wire from the board going to ac connector .im just curious where did you solder the two wire white in the board?
Sir if don't mine could you please tell me the SMPS circuit diagram of all ATX model available because i watching your video it's very useful and good knowledge gain sir kindly send any upload link or any
Dear brother Haseeb
Would you be kind enough and make a video about the difference between non inverting and inverting input and why it is used with IC's
and if you explained it before,in which video
Thanks
Big 👍 dear for your great talent✌️
Great videos, very well explained. Could you make a video troubleshooting a mac pro 2006-2012 Power Supply. I didn't find in youtube any video talking about that. Can't get 5 volt standby. Cheers
Sir may I know if even the green wire and the black wire are not connected you can measure a voltage at the main cap Sir tnx
In standby section i got reading on 1st powersupply (big diode) 3.7v and 10v on second powersupply, i get 3.7v in standby(purple wire) and also green wire, mosfet is good, what do you think is the problem
soooo nice sir
great!
