- Here in this video you will see how to repair power supply for a digital receiver or a set top box. Such receivers are very common hence their power supply failure is also very common. switch mode power supplies or SMPS are a bit complex and sometimes difficult to repair for an average technician. So in this video I would explain details of its troubleshooting and repair. Also I would give general rules to understand any switching power supply used in household equipment. hope this video may help people looking for switching power supplies or SMPS repair. SMPS switching power supply repair is not very difficult if understood once. The general topology for most power supplies is the same. only small small differences makes them different from each other.

Bahut acha samjaya ha sir👍🏼👍🏼
Sir G, mery pas bilkul yahi board ha, main capcitor per 330v aty hain lekin vcc (pin 3 aur 1) per volt nahi aarahy. Ic change ki sd6834 lekin ab arahy hain per fluctuate ho rahy hain. Lekin output zero ha. Trannformer bahir nikaal ker check ki to primary per 2.2ohm hain. Jab secondary per 4ron pin 0.6ohm bata rahy hain. Kia tranformer ki secondry short ho gai ha? Ya koi or problem ho sakti ha?
Check all components on board. Replace defective components. Replace optocoupler and tl431 ic with new one.
@@engineerkohat bhai, sab component check kiye hain, all ok ha. Tl431 per volt nahi arahy. Out put section per koi b volt nahi ha. Transformer ki output per koi volt nahi ha. Transformer bahir nikala ha secondary winding k ohm bahut kam hain. 4ron pin per 0.6 ohm sy ziada nahi arahy. Kia ye reading tek ha.

Sir mere pass smps ka 1 circuit hai ooska praymary part jal chuka hai to ham transformar laga sakat hai kya 3.3v 5v 30v 5v 22v 12v
You will need very big transformer if you want to change smps into conventional power supply. Better you should get the burned part and repair the original. Or otherwise you should take the universal smps fet board and connect it in your supply to bring it back to life.
Par oos smps circuit me 5 alag alag volt ke point hai or ground pakad kar 10 point hai or voo circuit kahi milata nahi to mai kya karu
not sound in receiver strong plz help
Saircuite ko repearing ke liye bataye
Is video may detail hae.

بھائی اس کی پاور سپلائی وولٹیج چیک کریں۔ اگر آؤٹ پٹ وولٹیج دیر سے آتے ہوں تو پاور سپلائی کے تمام الیکٹرولائٹک کپسٹر تبدیل کرکے نئے کپسٹر لگانے سے آپ کا ریسیور ٹھیک ہو جائے گا۔
Aapka taluk kis district se hai agar TCS sy receiver bheja jaaye to kya moram mat ho sakta hai please bataen.
Receiver ko Kiya hua hae?
Sir mary pas ek reciver hai el 8888 us ka red light wla masla hai voltages bhe thk hai supply ki bhe ic ki bhe sb us mein flash change kr ka programmer sy sphe1506g v1.9 ka software bhe kiya phr bhe red light hai plz help
اس کا پروسیسر چپ کا مسئلہ لگتا ہے۔ اگر پروسیسر چپ آسانی سے ملتا ہو اور تبدیلی آپ کے لئے آسان ہو تو اس سے صحیح ہو جائے گا۔ واسلام۔

Bhai me 2 new power supply laya hu market se lekin receiver on nhi ho raha. Purani suply k capacitor bhi change kar liye 16 v.1000 uf .or 10 if 400 v phir bhi bat nhi bani ...?
Ap thasali say check kejeye kiya problem hae. Kiyo on nahi ho raha? Nai supply kay voltage match nahi kar rahay hon gaay.
thanks sir meri same problem thi ye fuse jala howa tha main na without chacking is ko same thi laking differnt value ka fuse replace kiya chal raha hai reciver or diod main na check nai kiya kya khetay hai ap dido dobar chek kar lo ya reciver running main rahe ga dobara folt nai aye ga
Ge bhai abhi is ko test karnay ki zaroorath nahi. Agar diodes kharab hothay tho fuse nahi tehrtha balkeh usi waqath blown ho jatha. Next kabhi bhe kisi equipment ka aisa fault ho tho components test karnay kay baad hi fuse replace kejeye. ap kay case may components theek hen bas kisi waja say fuse urh giya ho ga. Ab is ko chalnay den.
@@engineerkohat sir kya ap apna number da sakte hai ik problem ka sloution chaia tah
