- in this video number {972B} Safety checks before applying power to any circuit for testing, i explained how to repair electronic circuit boards, how to perform safety checks, visual inspection, cold testing, checking components on power rail and output stage. we can use these steps to perform a component level repair for any industrial electronics circuits or commercial electronics circuits.

Boy, did I get so many shocks from big capacitor when I was a beginner or as some would say "a rooky", so many shocks, I was terrified of this boards. It forced me to thoroughly investigate how it works and how to approach it safely, since my older brother required me to do repairs on early inverter air conditioners, back when was very hard to find schematics or any good source of information.
yes. it is a hidden enemy in the circuits. so it is my pleasure that i am sharing my experience, might be it may informative for someone
Amazing work haseeb brother if you don't mind i wish inform you that i see this is two weeks ago the battery voltage of your digital multimeter is very slow and you're still using it...? So I'm sure you know that while using it will gives you wrong results so we thanking you a thousand times for sharing your great informations ☺️🙏🌺💐🌷
It's good to know the cold procedure to limit the risks when powering up 👍👋👋
Thanks for lovely efforts to teach the world one of the the sciences of Great God.
thanks a lot for your valuable support
Excellent thanks for sharing this informative video keep sharing
You are a very good teacher.
Nice sharing brother
Haseeb is one of the best in he's field on youtube!👍

VERY INFORMATIVE, you are very good at this, watched several videos, very interesting and thank you for sharing the information.
it is my pleasure
thanks for your encouraging words
please accept my best regards
Informative key points in repairing. Thank u so much. God bless you.
Very good information God bless you ❤❤❤
thanks very much sir for sharing your knowledge,God bless.
جزاكم الله خيرا
Very good information. Thank you sir.
I really enjoy your classes and practicals.Thousad thanks and prayers,Sir.I enjoyed your Protocol of testing steps just as a patient being examined at hospital.Kindly clear my one doubt.After testing for short in pcb /input resistance shall i test all components or power board to see some hot component- to get clue of damage localisation.Imay be a foolish beginner ,kindly excuse.Kindly explain.

Belle vidéo! Merci!
amazing explanation
Hi Mr tank you for every videos you make it is very helpful for me since I subscribe your chanal I improve much can you pls make video on invertor refrigerator PCB board how they work how we troubleshoot how to maintain
it is my pleasure. sure i will try my best to arrange a full detailed practical
@@HaseebElectronicsAs matter of fact, explain anything related to electronics you find.. you teach well sir
Thank you professor, very good video. 😊🤍
Good work
Thanks for sharing 🙏
Thanks...sir ji....
I wonder why you have used ohms mode for testing the input of that low power section. However, on the video number 684 you have explained the importance of diode mode for testing the input terminal.
Allah razı olsun.
Nice Sir
Thanks
Assalamualaikum Bhaiya....
Plz you can explain how does an ac non polar capacitor work in motor Or ceiling fan....
And why it changes its rotation direction
When we interchange starting and running terminals.....
I know how it works it's only superficial
I wanna learn his deep working
Plz plz explain
in hindi with deep details..
If you read this comment...
. . .. . .Have a nice day 💖💖💖
Hello, please add Persian translator too, thank you ♥️❤️

Grazie ❤️👍
🌷🌷🌷
In upcoming videos we need more explanation about IBM
👌👌
👍
❤
thanks a lot
do you knows how the MOV works in power supply
kindly check video number 411. and please give your feedback
Tks for the tips.what is uvw?
it is 3 phase output after IPM
👌👌👍👍
👍🤲
I never seen inverter using a tranformer from the secondary with out centre winding using an NPN and PNP I build it’s works this project it not in the Tube channel
Haseeb bahi kisay hain ap
yes sister i am fine. Alhamdulillah
💯💕
best regards and special thanks
