Bhai bahut saari electronics related videos dekhta hoon indian youtubers and foreign youtubers ki, but aaj tak aapke jaise clear electronics, fault finding and possible repair samjhane wala nahi dekha. U hv good knowledge of your field. Keep it up.
आप को बहुत अच्छी नॉलेज है और समझाने का तरीका भी बेहतरीन है। गुरुदेव मेरे पास 12v 5amp 60w का एक पावर सप्लाई है मैनें इसका ब्रिज रेक्टिफायर बदला है । इसको ऑन करने पर खट-खट की आवाज आ रही है कृपया मदद करें गुरुदेव।
This was a great repair...really an interesting problem and interesting solution. Sirf transistor ke mismatch ki wajah se problem ho Raha tha... Bahut hi interesting problem tha🙏
Sir aapke is video ki madad se main ek 12v 10 amp. Ka SMPS thik kar Diya Hoon.Thankyou Sir .Mere dusre Same power ka SMPS Mein out put 13.94 volt maximum nikalta hai .Main 14.25 volt chahta Hoon.Please help me.Namaskar
Sir my hand folded request ..start training people ..open a institute or work shop .. or if there is any such programme do every one let know about same..
Bhot zabardas sir ye masla mere pas bhee bhot ata hai Mai is maslay Mai 13009 k sath 4.7uf50 volt k dono capicator bhee new laga deta Hoon or driving chopper k dono transistor bhee c1815 k new laga deta Hoon kabi kabi ic ka bhee masla ata hai Tl494 ka
Sir, LED flood light driver repair pr video banao.🙏 jisme vltg fluctuations or Dead driver repair ki Puri information ho 🙏 Bridge vltg milata hai, pr aage DC o/p nahi ata.🙏
Nice sir ji...i watch all ur videos as these are very interesting n informative. Ur explaination is very good..plz make video on how to measure battery current (amps)
Namaste, I Have a question regarding my Meanwell 24v 10Amp power supply, the thermistor, power transistor, mosfet 20n50k, ea1 transistors And few diodes were short. I replaced all these components and connected the power supply in 100w series bulb. I get 24v output but the series bulb glows full brightness and always on. If I connect directly again all the components will short again, I physically checked all components but could not find and short circuit. Please advice as I have spent lot of time and efforts to fix, but no luck, thanks
hello, i have many of your videos and they are extremely helpful for beginners. I have a similar problem symptoms like this smps. my smps 12v 10a is giving output 12v and the preset is adjustable upto 14v but when i put load on it it would not work. I have one transistor hotter than the other so I interchange their place but the same side gets hot. I have also checked small npn transistor like in the your video and their value is ok. I have desolder many capacitors and resistors and diodes but did not find any of them bad. i was hoping if you could suggest or guest which component might be faulty. thank you very much for all your videos
Sir, mere paas ek cpplus power supply repair ke liye aayee hai. 340 DCV ban rahe hai.humne mosfet 7n65 r aur ic utc3843 change kar diya hai .optocupler bhi change kar diya hai.lekin 12vdc Nahin ban rahe.kaise theek karein.please batayein.
60watt ka soundbar hai uska power supply kit khrab ho gyi hai market me kitne ka milega uski power supply kit aur kitne volt ki power kit aayegi 24v 2.5amp ki ya 12v 5amp please bata do
Very nice and informative video. Keep it up 👏👍😊. Sir iss tarah k fault mein transformer k kharab (faulty ya damage) hony k chances kitny % hoty hein. In other Words, kiya big transistors ya other components k short hony se iss SMPS power supply ka transformer damage ho Jaye ga ya uss k bachny k chances hoty hein. Ya phir transformer damage nahi ho ga. Please share your experience with all your subscribers.
Sir ek smps hai jiske 5n60c MOSFET, 4148 diode, 9014,9015 transister , kuchh Rasistance kharab nikle the maine badal diye ... Ab smps 24 volt ki jagah 9 volt out kar rahi hai Feedback circuit bhi sahi hai..... Kya problem hongi...bataye please..
Hi sir I brought a second hand power supply 12v 30 A to run my car amp in home. It turns to be damaged. Now to repair that I have watched all your vedios they are amazing Plz help me repairing it by my self guide me. During diode check in found one of my MOSFET gone and also I found that there are two different MOSFETs which are SR B30 C2625 A4C 030 AND SR NO3 C2625 A2G 006 ( faulty) so should I change with the same value or I can change it with greater value like similar to other one. Pl help
pawan sir ji, 12v 10 amp smps main. short component badal kar, on hua, dc voltge, 2v aa raha hain. transistor badal kar vi 2 volt aa raha hain, kya problem hoga sir?
भाई मेरे पास एक 12V 15A की पावर सप्लाई है जिसे लोड देते ही वोल्टेज घट जाता है , किस पार्ट की वजह से वोल्ट कम होता है , 12 से घट कर 7 volt रह जाता है कुछ भी यूज करने पर plz reply
Sir, merepas canon photocopier mc ka smps hai. Woh mc may lagate hi chalta hai or voltage ve dikhata hai . Magar mc ke bahar multimeter check kore to 0 voltage dikhata hai but o accha hai . Iska Karan kya hai, ap chaye to iska part no vi de sakta hai.pls
Assalamoalaykum bhai saheb load connect karte hi output voltage 12 se kam ho k 7 vold ho jate hun plz guide kar den ye 12v 30a ki power supply me ho raha hy
