This video is very good and useful. I paid 65 dollars for ebooks from Justine Yong from Malaysia. I have purchased his first book which was Electronics components testing ebook. That I was paid approximately 40 dollars then I purchased his 2nd ebook which was SMPS repair guide and that costs me around 65 dollars. I want to inform people here that you have acquired 70% information from that ebook in this video. People who does not able to purchase that book can get knowledge from this video. I request you Sir to make one video on electronic components testing. I know that one video will not enough for such a huge topic but you can make something related to.
i salute you for your golden and valuable words.
it is really so valuable for me that i cannot express in my words
JUST:-
please accept my best regards and special thanks for considering my efforts
Sorry can you send full name of such e book for me?
Good 👍
❤
Assalamoalaykum. kindly make make one video on electronic components testing. badi karam nawazish hogi aap ki.
Sir mujhe electronics me bahut intrest tha sir lekin jab maine is course ko bahar seekhne ki kosis ki toh ishi course ko sikhane ke liye log bahut jada paise maag re the ,lekin maine aapke videos dekh dekh kr mai seekhta hu or daily practice krta hu ,smps repair krne ki ...Or mai aapko batana chaahta hu ki aap jo course de re ho wo itta keemti hai jiski koi hadd nhi ,aap mujh jaise gareeb baccho ke liye bagwan ho sir love you from india...❤️
Love you dear brother
and wish you huge success in your life

Salaam Allaikum -warahmatullah hi barkatahu, Haseeb Sahab Aap ne kaha comment karne ko... Lekin meri samj ye hai ki, comments aur suggestions...
ki si bhi subject per, wahi desakta hai aur woosi ko comment karna chahiye jo halaat se behtar ho...maine aap ke bahut se smps trouble shooting videos dekh chuka hoon. MashaaAllah aap ki knowledge superb hai, Mai Bahut admire karta hoon aap ko, electronics may trouble shooting aur design mein Aap lajawab hai. Mera taroof ye hai ke Mujhe bada interest hai electronics mein, Mai Basically Electrical Engineer hoon, maine middle east takreeban 15 saal job kiya hai, india may bhi 15 saal kiya. power plant mera experience hai,
mujhe electronics mein interest hai, thoda bahut trouble shooting karleta hoon . Aap ki knowledge ko dekh mai aap ka admirer bagaya.
Mera maana hai ke aap teaching profession se taaluk rakhte hai...mere liye aap genius hai...Allah-Rubbulizzat aap ko aur tarrki den.Allah
hafez.
wa alaikum salaam bhai
i salut to an experienced engineer
i am also avionics engineer
Just mera plan he k jo experience mein ne gain kia he wo logo tk deliever kia jaaey. is line per kaam kr rahaa hoon
I'm a biology student but i love electronics once i watched your video and it cleared my concept how SMPs work. Bro Apka teaching method bhot acha hai, ap mehnat krte ho, dil se smjhtay ho, hum sirf shukria kr skte baki Allah apko ajar day. Ameen.

कैसे हैं सर अस्सलामु अलैकुम? सर, बहुत अच्छा वीडियो था। महोदय, इसे शब्दों में व्यक्त करना संभव नहीं हो सकता है। महोदय, जैसा आपने कहा, मैं हर समय अभ्यास कर रहा हूं। आपके वीडियो देखना बहुत अच्छा है। महोदय, मुझे लगता है कि आपके हर शब्द में तर्क है और मैं आपके नियमों के अनुसार हर शब्द पर जितना हो सके उतना काम करने की कोशिश करता हूं। महोदय, आपने मुझे जिस तरह से प्रस्तुत किया है, मैंने UA-cam पर किसी को भी इतने सुंदर तरीके से उपस्थित नहीं देखा है। आप वास्तव में एक अद्भुत व्यक्ति हैं। महोदय, आप हमसे अनुरोध करते हैं कि हम आपको नए वीडियो दें। सर मुझे व्हाट्सएप पर कोई एसएमएस का जवाब न मिलने के लिए बहुत खेद है। सर मुझे आपसे बहुत सारी जानकारी जानने की जरूरत थी जो मैंने आपको व्हाट्सएप पर एसएमएस के जरिए की लेकिन मुझे व्हाट्सएप के किसी भी एसएमएस का कोई जवाब नहीं मिला।
मैं आपके सुनहरे शब्दों के लिए आभारी हूं आपके संदेश के लिए धन्यवाद मेरी बाईं आंख में समस्या है कि मेरी आंखों की रोशनी अचानक कम हो गई थी और पिछले पांच महीने से मैं अत्यधिक मोबाइल का उपयोग नहीं कर रहा हूं
इसलिए व्हाट्सएप संदेशों को 10 जून 2021 से जवाब देने की प्रतीक्षा है। सभी संदेश अभी भी लंबित हैं और मैं उनकी जांच नहीं कर सका, क्योंकि डॉक्टर ने फोन का उपयोग कम करने की सलाह दी थी। अब मेरी दृष्टि सामान्य हो रही है और मैं व्हाट्सएप संदेशों और ईमेल को पढ़ूंगा और उनका जवाब दूंगा
I Am from India Super class. nobody will teach like you SMPS full postmortem done

Thanks for explaining in a best way. If Chinese made charge of 10/20 amp are considered, would be helpful for many people.
Superb sharing
Zabrdast amzing woooow
You are great Mr. Haseeb. Your lessons are truly technical and very sincere. I am your fan from India just above 80 yrs and love to repair my home appliances. Although I was a civil engineer but electronics is interesting. One question - most of the times we don't have circuit charts for the device we desire to repair.

Very well explained. A great thanks to you Sir.
You are most welcome
Dear brother, very nice and useful information. I will be waiting for the change of resistance value to reduce the threshold voltage of IC. Thanks
MashaAllah sir aap ne ache sy smjhaya Huwa h thanks 👍
it is my pleasure
Hello Sir,
Apke SMPS ke related videos bohot hi achi aur detailed hoti he. Aur muje bohot pasand aati he.
Electronics meri hobby he to muje weekends me hi time milta he.
Sir muje ek SMPS supply me issue aa rahi he. Mere pass ek 24v 2amp ki RO SMPS spare me thi jo mene socha ke ek adjustable supply ke tarah use kar saku taki muje kafi project me kaam karne me asani ho.
Isliye mene TL431 ke reference pin me 68k ka smd resistor remove kiya aur 50k ka variable resistor lagaya. Shuru me output 20v show hua aur variable adjust karte hi voltage bhi change ho rahe the. Lekin jab mene voltage zyada drop kiye to output voltage stable 10v ho gaye aur fir variable adjust karne ke baad bhi voltage change nahi ho rahe the.
Mene primary side pe ek bohot choti smd IC dekhi jiski datasheet bhi available nahi he internet pe. lekin components dekh kar to lag raha he ke ye ek current mode PWM IC he jiski frequency inbuilt hi set he kyuki koi RT/CT nahi he. Sirf 6 pinouts he jo VCC, ground, feedback, current sense aur pwm output lag rahe he.
Pehle muje laga ke variable ke karan IC damage ho gayi he to shayad power MOSFET pe voltage drop ho rahe hoge gate pin pe. To mene primary ground aur gate pin pe DC voltage check karne ke liye multimeter probes touch kiye. To switching slow hone lagi aur switching sound bhi sunai dene lagi fir ek time pe itni slow ho gayi ke shayad gate continue on ho gaya hoga aur power MOSFET aur current sense resistor dono short ho gaye. Dono components remove karke continuity check karne pe resistor open aur MOSFET short circuit dikha raha tha.
Shayad gate pe frequency aur duty cycle mode me check karne ke bajai mene voltage check kar liye. Mere pass expensive multimeter nahi he aur usme ye functions bhi nahi the.
Power MOSFET 8N65 tha aur current sense resistor 0.39 ohm 2 watt ki thi.
Shop se muje 8N80 power MOSFET mila lekin current sense resistor nahi mili.
Muje kuch doubts he jisme apki help chahiye thi.
1. Mene datasheet check Kiya to 8N80 ka RDS-on 1.5 ohm he jabki 8N65 ka below 1 ohm tha. Pehle se around 50% zyada on resistance he to kya MOSFET pe zyada power loss aur heating issue ayega? Kya ye power MOSFET lagana thik hoga.
2. Bina current sense resistor lagaye agar sense pin ko ground se connect karne pe koi issue to nahi hoga.
3. Kya ek zyada gauge ka copper wire hum current sense ke liye use kar sakte he? jese multimeter me hota he 10A ke liye.
4. Agar original IC kharab hogi to mere pass UC3843 ke kafi IC's he wo me pinouts ko track karke replace kar sakta hu. Lekin muje pata nahi he ke original IC ki kitni frequency he to kya aisi koi common switching frequency he jo mostly use hoti ho SMPS ke liye? IC replace karne par VCC drop karwane hoge kyuki UC3843 ko 7.5 se 8.5v pe operate karna hoga aur muje lagta he ke shayad mene variable karne se pehle VCC voltage check kiye the tab 20v aa rahe the aur aab 10v aa rahe he.
Sorry Sir lekin SMPS ki ye halat karne ke baad bhi me isse variable ke tarah use karna chahta hu taki muje expensive bench power supply na Lena pade. ye 48w ki supply kafi he mere liye aur iske components bhi achi quality ke he.
Thanks in Advance Sir waiting for your feedback.
बहोत अच्छी जानकारी दी सर धन्यवाद साधुवाद 🙏🏻👍🔥🙏🏻 👍👍
