Very nice best of luck uncle ji ❤❤❤
خوبصورت انداز ہے آپکا سمجھانے کا چھ وولٹ چالیس ائمپیر کی سپلائی کی تفصیلی ویڈیو بنائیں
बहुत अच्छा मार्गदर्शन।
धन्यवाद सर
Very good Bhai
Very nice lecture and way of explaning is best .I have never seen such a nice channel.Thanks sir stay long life.Pakistan
Grate job sir ji.
Bahut vadia tarike se bta rahe hain aap😊
Jabrdast
Very very power full knowledge, Sir....All explain with very deeply & technically
Excellent
Supper sir❤
Very very thanks for informative video.
Super
sir thank you very much for making good video
Thank u sir
Dear
excilent and very very good informative vedeo. i seen first time to seen how checked smps step by step.
now i understood how checked voltage on
every section if out put voltage come low.
with thanks
Tks
Bahut badiya video sir ji👌👌👌🙏🙏🙏
Uncle je double opto coupler walee supply pe video banaye or feed back kon se opto coupler se leney hai bataye
very useful thank's
Nowledgeable and informative vedeo. Thank u so much. Pls share your no. God bless you.
Smps designing ki Koi Book Suggest karo sir ......
sir sari voltge chek kar li
Sir dth free dish ke secondary me jo dc diod lag te he vo kon kon se numbar ke hot he.or dc diod 154 sarkit me laga huva hota he agar vo na mile to uski jagah kon sa diod laga sakte he.plese sir replay
high frequency diode कोई भी हो लगा सकते है। धन्यवाद
Har Har Mahadev tau ji Jai Ho Baba Shambhu.......
Very nice video sir thank s
Hi gurujii thq for your good video I have one doubt please clarify it sir if possible I have a computer led monitor ka power supply 12volts module as per my knowledge I have checked as per your video also but I can't find exact problem is not getting output 12volt I change transistor upto primary and secondary also but no out put
check auxiliary winding diode and chhota capacitor voltage. thanks
@@Unclegyan sirji i check that cap also I find that voltage is around 40to50 varying on small capacitor I checked opto also it's good but output is not getting
Uncle spray machine charger my low voltage show karta hai iska video banaya please.
Sir agar vcc pe fluctuate volt aa rahe ho or ooutput me koi volt na mele to kya karen bataye
output side में capacitor या resistance या diode शोर्ट है। चैक करें। धन्यवाद
सर कइ कारीगर ऑपटो कपलर के 1/2 सीरा शोर्टकरके होट/ कोल्ड विभाग चेक करते है ।ईस पर एक वि,बनाईए। धन्यवाद। नमस्कार।
इस पर वीडियो बना हुआ है। प्लेलिस्ट में चेक करो। धन्यवाद
Dear
Uncle Sir
yesterday on 1st february 2023 sir i given
detailed information after your reply. pls
see and guide to me. I highly oblige for this kind favour.
with thanks and regsrds

Namsty. Sir
Dear💕. Sir. Ic. Ka. Nambar. De
dear
Uncle
i have tested our smps first tested
main capacitor negative to main widing
primary second pin ac voltage getting zero
and small capicitor 50v 22uf dc voltage getting only 2volt.. what is trouble if primary
second pin not getting ac voltage pls reply.
Tks
check Autocoupler voltage
@@Unclegyan
dear uncle thanks to reply
will inform you sfter checking
with thanks and regards
Dear
Uncle sir
A lot of thanks for reply.
our circuit problem when our two smd smalltxr burnt and number not visible.
replaced j3y and 2ty txr after that problem
arising and low voltage coming while changed 4n60 ..main capicitor and small
capacitor .ouput capicitor 1800uf16v and
Mbr 20100ct including optocopler and tl 431
all changed. but stll out put comes 5.91dc v.
as per your advise optocopler pin 3-4..3.4vdc and pin 1-2....01vdc .I think sir
both smd txr right choos or not i do not
know. smd connection like this.
(1)j3y(npn) (2) 2ty(pnp)
base(+dc) Emitter(- dc) main negative
collector ....base connected
emitter..... collector..connected
smd txr base + voltage not showing
collector+base voltage going to optocopler
pin 3. and collector+ base votage going through smd capicitor and resistance
15000 to 4n60 mosfet source pin.
our 4n60 Gate pin main dc plus voltage
through 2.20mega ohms resistane. one side
resistance connect positive 340 dcv another side Gate pin on this gate pin only
getting one volt dc. this is situation sir.
pls advise me. if any whattup number pls share. highly requesting if you like.
with thanks and regards

यह जानना उपयोगी होगा कि सर्किट की जांच करने के लिए आपने जो तरीका दिखाया है वह केवल डीटीएच एसएमएस पर लागू होता है यह सभी प्रकार के एसएमएस पर लागू होगा यह बताइए सर।
धन्यवाद।
सर्किट का डिज़ाइन अलग हो सकता है। पर जांच करने का तरीका यही है। धन्यवाद
SIR,
THANK YOU SO MUCH FOR YOUR KAIND INFORMATION 🙏
Sir g apna number do
Thank u sir
