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
Good 👍
Sir solder remove ka mashin kaha se leya ha
Asslamo alaikum,,sir mujhe apki zarurt pad gyi h,,,ye ac dc bulb ka working smjha dijye with diagram,,ac section to smjh ata h par dc section me confusion h.plz ek vide sir..
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 ...
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.
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
Sir Thank you for reply if contineus trigger of transistor accures then what is trouble shooting method thank you sir
JazakAllah
shukran
👑 for you
JazakAllah
