- in this smps repair tutorial i explained how to fix SMPS Output voltage fluctuation problem, How To Repair SMPS Switch Mode Power Supply Low OutPut Voltage, i explained in urdu hindi language.
smps fluctuation fault have many causes. basically it happens when smps controller is unable to find feedback or some over voltage or short circuit protection is active, in this condition we have to search the root cause of the fault based on nature of fault
Please check other videos on same fault

it is a TOP214 based flyback converter power supply, in this power supply that output was varying 0 to 1 volt instead of 5 volt. the output was unregulated and fluctuating. top214 ic was unable to receive control voltage (feedback voltage). one zener diode was short circuit in secondry side, which was causing to drop all the output in secondary, so TL431 was unable to find feedback voltage and optocoupler was inoperative, that was the main reason that the optocoupler was not allowing to pass the vcc auxillary voltage to the control pin of the top214 smps controller ic.
i explained the functional description of the circuit with circuit diagram & datasheet. so the troubleshooting becomes easy when we repair with schematic
also i discussed smps basics. after watching this video you can capable to:-

valuable work
best regards bhai
ماشاءاللہ بہت ہی اعلی ، تفصیلی و علمی ویڈیوز ہوتی ہیں آپ کی سر جی ۔جزاک اللّہ خیر
You are loveable person with great skills......i m an embedded system programmer....and hardware designer....even though I watch ur videos very often....actually ur heart whole honesty impressed me alot...it looks like very obvious u want to spread the knowledge you have...and also not greedy to flourish ur channel....
सर मैं repairing का काम 23 साल से कर रहा हुं.उमर भि मेरी 55 साल की है.लेकीन smps की डिटेल्स मैने सिर्फ आपसे ही सिखी. आपका बहोत बहोत धन्यवाद सर.
महोदय, मैं आपके सुनहरे और मूल्यवान शब्दों को सलाम करता हूं। यह मेरी खुशी है कि मेरे प्रयास मेरे दर्शकों के लिए मददगार हैं। मैं अपना अनुभव साझा कर रहा हूं ताकि कोई लाभ उठा सके। विशेष धन्यवाद और शुभकामनाएं
Now I understanding smps circuit because of strongly deeply expling to us circuits, thank you sir .
Exilent work sir thnx
U r right the basic knowledge of any circuit plays key role to repair any think
Sir Very helpful video. Knowledge based video.

सर जी, आप एक विडिओ बना दीजिये- क्लास D ओडियो बोर्ड की सर्किट के बारे में....…..
आप बहुत ही अच्छे से समझाते है।
मैं पिछले 2 साल से बना रहा हूँ। सन्तुष्ट नही हो पा रहा हूँ। सिंगल-सिंगल मॉस्फेट पर चलता तो है लेकिन मॉस्फेट बढाने पर ओवर हिट होने लगती है। कॉफी परेशान भी हूँ।
Mashallha very nice and beautiful tutorial. It is really very helpful and useful. Watching for full support. 💕💕💞
Thank you so much
Excellent knowledge sharing. Keep it up. Thank you sir.
