many helpful.... thanks admin
Very well explained. Thank you.
Helpful video 👍 I like it
Aapka bahut bahut dhanyvad
Awesome explanation sir
.....sir iseh eak variable power supply banaiye 24v to 0v
In next video....
Excellent explanation.
Thank you sir ur great from Pakistan
Excellent 👍, very helpful video
सर ! इस तरह के समस्याओं पर सैकड़ो वीडियो बना है किंतु आपके बनाये वीडियो का हर समस्या के ऊपर जबरदस्त समाधान देखता हूँ। आपके समझाने में भूल से भी कुछ नही बचता,इतना बारीकी और गभीरता से आप समीक्षा करते हैं के कण्ठस्थ हो जाये।
ये शायद आपके उच्च ज्ञान व बेजोड़ व्यक्तित्व के कारण होता है।
(कंप्यूटर ups से सम्बंधित एक समस्या है मूझे आप हां कहें तो बताये,जिससे मैं आपका आजीवन आभारी बना रह सकूँ।)
आपका सहृदय धन्यवाद।
Excellent Mishra ji
hello sir ji
please reply. mere smps me dc side ka capisitor 200uf/10v fata hua hai
kiski jagah koi or capisitor laga sakte hai
Well explained sir very nice... Thnx
Sir, what is the right one or number of MOV to be use in desktop computer psu. I couldn't find the number because it was burst.
Thanks you sir ji
🙏🏼🙏🏼🙏🏼
thanksksksksk sirrr .mera atx ma dono capacitor explode ho gaya tha to maina usko ek single 120uf 400v sa replace kr diya tha🤣😅
Great great great sir
Samjhate bht acha ho ap Bhai good
Thanks for feedback..
Bhai aap super ho thanks bhai
good explanation.. Please let us know how to solve current in SMPS body when checked by a neon tester, provided the current supply face, neutral, ground are correct
Real Knowledge!!! Love!!!!
Mistake in ckt diagram. Collector of T1 connected with (-) supply line & Emitter of T2 is connected with (+) supply line. It should be opposite!
You are right circuit digram power transistor T1 connect with +, & T2 connect with -, ... there is issues with connection in circuit digram ..sorry for that
Then why the collector of an npn transistor is always connected to the positive supply line and emitter to negative?
I maintain it in video descpriction... & also thanks you for your attention
Ok🙂
Thanks it helped me
Very nice video for learning. I have noted that in my computer SMPS the thermistor at the input supply is completely burnt. Will you please let me know the specification of the thermistor suitable for replacing the same ? With warm wishes.
Sir i like this video very nice
A very well explained tutorial.HS8110 ic pin 13shows continuity to ground&reis.burned.If ic is faulty?what is the value of reis. connected to pin13&may the ic be replaced by a new?Hope&wait for ur reply
Sir mera smps automatic 1 second m on off ho raha h to manay usko open kiya to uska non polar capicator 105j 250v open ho gya to kya is ki jangha kisi or value ka capicator laga skte h laga skte h to kon si value ka lagay
Sir, can you tell me that value of MOV is used in this SMPS?
If possible please upload a video on MAC PRO (tower computer) power supply repair
Thanks
Sir mera SMPS on hota hai or band hojata hai..kya problem hai.
Bataoge.
Very nicely explained sir
hello . what is the approx value of resistor that you touch at 2.47 minutes ?? . thanks
Sir mera smps ke green or black ko short karte hi smps chaloo hokar turant band ho jata h
Pls solve my problem.
Shandaar vdo ✌️
hello, kya main 12 volt ke sabi wires ko combined karke motherboard main single se multiple wire kar sakta hoon. actually main muje smps ko cabinet ke bahar rakhna hai and smps se cabinet main 7 or 8 wire le jane hain colors ke according. main samja nahin sakta but smps ko cabinet se bahar rakhkar laptop ke adapter ki tarah use karna meri requirement hai. Thanks
Sir is power supply ko DC 220 voltage De sakte h kya?
bestec atx-250-12z rev.:h1 SMPS ME GREEN OR BLACK WIRE KO JOD TE HI SMPS MATLAB KE USKA FAN EK BAR ON HO KE TURANT OFF HO JATA HE TO KYA FOLT HO SAKTA HE...PLS..REPLAY...pls reply
Jaise capasiter ko kisi dusre number ka laga sakte hai Kya ya usi ka number ko hi laga na hai
Sir good evening.Ats power supply mein double diode ke leg mein jo resistance laga hai,uska value aap bata sakte hain kya?
agar green wire par 3v a rahay hun or smps fan trip karta hai kiy masla ho sakta hai plz
explanation is Good. But mistake in circuit. the chopper power transistor pair collector should be connected to rectifier +ve & emitter should be to rectifier -ve.
Sir smps me 3.15 A fuse ko 5A ya 2.5A se replace kar sakte hai
Rectifier ke liye 2diode RL207 ka or 2diode 1N4007 ka use kr skte h kya sir ...?
Very good explanation
sir ap na bhot axa samghaya ha lakin please thora or detail ma expain kr dia krain shukria
ATX repairing ka part wise video banaye , RUclips par ek bhi video dhang ka nahi h, fault sahi karne ka video banaye pls
Mai jab apna Pc SMPS se +12v aur -12v yani dono 24volt se apna dc fan chalaya to almost 5seconds ke bad smps kharab ho gai,
Usme kya kharab hone ke chances hai.
Please reply me.
sir mera smps ka Pf capasitor pura fat gaya hey kya wo replace karke lagane sey smps salu ho jagega...? aur sir sabhi smps ka pf capasitor sab same hi hota hey kya...?
Which ic is used here in feed back...
Good explanation, but role of optocoupler ic how it works not explained.
Sair toto riska ka jo smps charger hotahain uska upar koie video banaia to accha hota.
Thank you
Seem like a great explanation, if only this is in English, I can only assume what you said.
Sirji 3.3v rail pe 3.5v aaraha hai.. kya dikkat ho sakta hai overvoltage ka kaaran??
Konsi bhi black wire ko green wire kay sath attach kar sekete hai kya?
If voltage between blue and black is below rated voltage then which is said to be faulty (measured voltage -9.6vdc rated voltage -12vdc) ??
Sir mere smps me greey wire me 5v. Aa rha hai aur baki me nahi kya pro. Ho sakta hai?
Mov blown ..I replaced them Instead of 12v am getting 13.4 can I use it
Check capacitor weak or leak on 12 volt output section
Perfect
Sir home theater ki repairing ka vedio bhi bana dijiye
nice
Great work
Best knowledge
What is the ic used to switch transistors ??
Switching mode ko short karke direct karna possible he kya?
Flood light ripening ka vidio banaiye sir
Sir, smps fuse and bridge rectifier short please give some suggestion,
Sir pf ki value kiya hai or reson for its blown
Outer section/cold section का जो बडा coil है वो जल कर ब्लॅक हुवा है , क्या प्रॉब्लेम्स हो सकती है , और कैसें रिपेअर किया जा सक्त है?
Sir, in my SMPS +5VSB is good but green wire me 3.3v k approx. aa rha. jis wajeh se green nd black ko short connect krne pr fan start hote hi ruk jaa rha. Mujhe kis section me check krna chahiye & kon kon sa part khraab ho skta h plzz btaa dijiye.
Good explanation but ic ke bare mai knowledge thodi week hai wo thoda or clear kr lete jaise 16 pin ki koi bhi ic ek doosre ke jagah nahi lag sakti
Good thank sir
