{522} How To Repair Computer ATX Power Supply - No Power On

{522} How To Repair Computer ATX Power Supply, this computer atx psu power supply was dead. this power supply have +5V SB standby voltage on purple wire, 5volt PSON command on green wire. when green wire is made jumper to ground, it was main secondary power section was not turning on. while testing, i found 1N4148 diode short circuit in pulse transformer, this 350 watt atx power supply is using TL494 and LM339 ics.

السلام علیکم ۔۔ سر میرا ایک سوال ہے standby سیکشن میں 5 volt کی بجائے 12 volt آ رہے ہیں اور باقی کوئی وولٹیج نہیں آتے پاور سپلائی ورک نہیں کر رہی کیا issue ہو سکتا ہے

[@MarkPrince1317]

سرجی یہ مائنس 12v کیا ہیں اور یہ کیسے ہوتے ہیں مقصد کیا ہے مائنس 12v کا

Aoa sir g.bootstrap circut kiya hai? ye kam kaisay kerta hai ? Hs ka use kiyo kia jata hai? Or hs mn boots trap capicator kiyo use kia jata hai? Jaisay smd ic (mp1471) k sath hs ko use kiya ghiya hai sir please samja dein shukriya

[@rohtashsinghrajput721]

Sir atx power supply is having stand by voltage , on Ic 7500 is having voltage on pin 12 ,12 voltage perfect voltage on pin 13. 14, pin 4 is having voltage round 3.5volts but fluctuations secondly on jumpher to black and green voltage on pin 4 of Ic does not Zzero.IC is Kl7500 and other than green and purple no out put. Sir which section is to be examined. When you feel free ...

[@santanughorai5740]

Nice video

[@rajaimdadjanjua]

Good 👍

[@beinghuman9544]

As-salamu alaykum sir Thank u sir for educating us
In this video Time stamp 13:27 mins you told i will make the jumper between black and green wires if series lamp glows i will remve immediately.why and what will happen if lamp glows continuously.

[@haseebelectronicsurdu]

when we repair atx power supply. if there is something wrong in pulse transformer section, it can trigger output transistors permanently. which may cause to draw maximum current. in that condition, we must disconnect jumper to prevent the circuit

[@beinghuman9544]

Sir Thank you for reply if contineus trigger of transistor accures then what is trouble shooting method thank you sir

[@beinghuman9544]
