Fantastic!!how easily you find the fault!!experience is the best teacher.thank you very much from Spain!

😢السلام عليكم ورحمة الله وبركاته استاذي الفاضل على معلوماتك القيمة وجعله في ميزان حسناتكم استاذنا ❤❤❤❤❤❤❤❤🎉🎉🎉🎉

Emeğinize sağlık efendim. Sizden çok öğreceğimiz bilgi var. Ömür boyu başarılar dilerim.

Thanks for this vedio. This multimer is Good i want to buy one

This is unusual. TL494 needs 7V-40V. 3.9V is too low so I was thinking the fault was with the VCC input voltage, something like burned or open resistor. But as usual your diagnosis is correct and you fixed it :-)

Simply nice!!! My humble thanks

Mr Haseeb thank you for your nice video 's

good evening and I never knew that it would be so easy to repair the board

Very good and useful information sir thanks

Nice teaching sir thanks👌👍

Weldon keep sharing

obozavam da VAS gledam .Puno,puno pozdrava

Informative vedeo. Thank you so much.

Deep ❤knowledge ❤share pranam❤

Super 👍 sir thank you

❤hesseb brother

😊you are always good

Sir this video is really different for me compare to other videos. Because your showing the ic pin detail to us, like this video here after please keep showing us. really this make sense to me. And one more doubt sir i check the data sheet, Vcc supply it should be 7-40v. But inthis smps only we received 3.7v. Is this acceptable supply voltage? Thank you sir.

Thank you very much

👌👌👌👍👍🌹🌹

Love you brother ❤

Thanks for your informative video. Can you help me troubleshoot smps dual output. 5Vdc ia good but no output in 24Vdc.

👍

Thanks for its shared

Sir apsay ek requ st hai please..kindly bu k converter design kardijeyey 72 to 12 volts ka . Design ,calculation and simulation k sath. Zindagi ka eshan hoga meray per.

Mr Haseeb thank you for your nice video ,s can you make this smps works on dc 48v input to 12v output thanks again

Could have shown the ref voltage on new IC.

wow amazing

Sir. Your video list the computer UPS repairing video is have? Please inform me. I likes all your videos. From Tamilnadu.❤

Nice! Please load test after repair? Components don't blow up on their own under no load. Why did the IC go bad? Do other failing components cause the IC to burn up under load? Voltage is good but useless without current capacity

If the control lamp connected in series with the 230V AC power supply stays on continuously, does it mean that the respective source has problems on the DC voltage output side? Thanks for the explanation.

Hello... the problem I have is not finding the problem and the power source (12 volts 30 amps)... instead of being 12 volts, the output is about 5 volts and the voltage changes very little by turning the potentiometer... I replaced two filter capacitors due to the loss of capacity (I tested the parts with a multimeter and a T7 tester) and the voltage of each of them is about 150 volts and the total is about 300... I also tested the MOSFETs with a tester and a multimeter and they are fine... I also replaced all the electrolytic capacitors around the switching IC... I also tested the transistors and all the diodes around the switching IC... one interesting thing is that the ground and VCC voltage I get is about 7 volts There is, and I think this voltage is weak!... But the REF voltage is about 5 volts... I have to say that I even changed the IC for testing and there was no change!... In short, I wonder where the problem could be.

Hocam bundan sonraki videolarda entegreyi sokmeden diyot modunda kontrol edermisin sonucu merak ediyorum ne aralıkta değerler verecek

Is the noise thats coming from the power supply when u applied 220 normal ?

Sir please SMPS me capacitor vcc voltage nahin aata hai kya kare sir please Hindi me boliyee dhanyawad

plz i did and tested the 12 pin give me 9.30v and Vref give me 5 volt but my main output is 4.5 to 5.60 and should be 12 Vdc tested the daiods and the caps and resestors nothing at all i just hearing nosie come out of the transformer the big one what i need to check thanks

Selamün aleyküm kardeşim. Bu entegreyi hemen tahmin ettin. Bunu nasıl yaptın. Ayrıca başka bir neden varsa ve yeni entegre yeniden bozulursa? Entegreyi düzeltince sorunun devam etmeyeceğinden nasıl emin oluyorsun?
