- Repair Computer Power Supply /ATX Standby Voltage Fail / Input short circuit
i explained practical How to repair computer ATX switch mode power supply SMPS very easy. this PSU had no output on STBY +5V standby missing, short circuit in input section, the fuse burnt out.
i shared my easiest and perfect troubleshooting techniques to repair computer AT or ATX power supply, i found rectifier diodes, fuse, power transistor, diodes in standby inverter section. smps concept and troubleshooting repairing or understanding repair switching mode power supply basics and working principle. how to troubleshoot input electromagnet induction filter, EMI, bridge rectifier and capacitor. we get 330 VDC at main capacitor. after hat the +330 volts are applied to standby power, which is SMPS and makes +5V SB, these stand by voltage are applied to motherboard which pull down the PS ON green wire to zero level, so the ENABLE OR REMOTE ON or CONTROL pin of #smps will go low that will enable pulse width modulation. and also i discussed smps basics. after watching this video you can capable to:-

Beautiful tips for computer power supply
Nice upload
Watching for the second time a good technique in isolating a bad component in the power supply component tnx for good presentation sir
Super video sir ji❤❤❤🙏🙏🙏
Great video sharing...I have a NOX Urano 630W ATX power supply, and it never turns off, without any motherboard, the fan is always spinning and the defect is always the same, it's turn on, I checked that the green wire (POWER ON) is in a short circuit with all the black wires. How can I resolve this? Could it be the output electrolytic capacitor? Could it be from the integrated output control circuit? Only I get turn off with the external switch supply !!
Super video dear Big like 15

Interesante tema de la alimentación de la PC,
gracias por compartir mi estimado Hasseb Electronics👍👍
Very well explained
Your video is superb Haseeb.
Corsair VS650 psu not power on
Though many RUclips videos regarding SMPS your video’s are practically oriented easy to follow with tips short cuts etc.
I have one request can you do one video how to check SMPS duty cycle etc using oscilloscope
Thanks
Very nice and informative
Superb troubleshooting process

Hi brother that's very nice 👍😊
Mashallah very good video 👍👍👍
which soldering iron you are using?
It is Weller WR3M Rework station, made in Germany
Thank you sir
now I know what to do first of testing,
And I will make a testing lamp too soon
You are most welcome

wonderfully awesome and perfect repair process. thanks for sharing
Thanks for making smps repairing videos. .very helpful for me. ...can you make one video about over current protection and over voltage protection.
very good information +41 nice up loud thanks for sharing
Informative and useful stay blessed
First, I like to appreciate you for this great exposure to all I had learnt from this video.
But, I like to know something that had been a concern to me about zener diodes. A lot of times, its code is not readable or available at all, then how can one know its rated voltage within a circuit?
From this video, you said that, about two of the zener diodes are not good, now, my question is, how were you able to know the actual voltage of the zener diode that was not good in that session of the circuit that has issue?
Thanks, as I await your swift response.
Hello Family! Good morning to you!

Hey my friend, awesome job on info to fix computer 😁👏👏
I use a 25W lamp for series bulbs. When it is connected to test a power supply, the bulb lights up with a low light. Is this due to low W value of the bulb or short circuit in power supply?
25watt lamp cannot provide enough current, that is the reason that it will glow at any good circuit
you need at least 60 watt or 100 watt
@@HaseebElectronics Thank you sir. After I connect 100w lamp and it's not any illumination.
👍👍 👍👍👍
I wish you a good start to the day
Take care 💚 stay healthy

Sir may I ask if there's a shorted component in the input or primary ckt whatever it is the series lamp will glow I I'm correct sir Sir tnx for your reply
@@HaseebElectronics tnx very much sir
Sir I have a desktop power supply. I have removed the cover. Once I connect mains power no out put. If I connect a 12 V / 60 W lamp the output is no stable. What may be the trouble? Please reply
Like it 👍🏻👍🏻👍🏻👍🏻
Sir what is the cost of the multimeter that you uses?
It is expensive stuff
Boht details se hr cheez explain krty hn ap..
Sir ji transistor or mosfet nahi mil rahe ho tab substitute kese lagana hai

Standby voltage is available but , after connecting green and black ground wires , there is no 12 volt and 5 volt and 3.3 volt output. Fan doesn't start , however there is some very high pitch sound from board.
My power supply standby voltage is okay but it's not turning on
if it takes a start and then output disappears, in this case voltage supervisor ic is interrupting
if it is not turning at all, please check PSON command or over voltage / short circuit detection circuit OR PWM controller section
@@HaseebElectronics bro i checked smps board and just connect to power at tha time home power break is off I'm check phase and nutrel with continuety tester in multimeter and it shows 890 something what is the problem bro?
Please stay with English . Perfect Vids
best regards and special thanks
@@HaseebElectronics Are you working in Saudi Arabia ? i kind of felt it when the coffee guy came :P
sir problem hai ek meri psu me jo pmw ke liye optocouler lagya uski ek pin par agar mai fingerr laga du to power supply on ho jati hai bina greeen and black ko short kiye par agar mai green ko short karu black se to thoda sa pankha ghumta hai fir band
or ek baat psu start nahi ho pati but agar uski standby section ke transfotmer me primary. me agar mai voltage check karu live chalte huye to multimeter awaz karta halki si and uske baad pasu me secondary voltage aajati hai
How much do you think it will cost me to repair from a repair shop
Watched 10:30
When i bypass 3.3v 4v 5v out put shows 16v but when connected to load output voltage goes down why
BE CAREFUL! THE CAPS in series have 340V!!
And he doesn't discharge the caps. The caps hold dangerous voltage for at LEAST 5 minutes after powering the power supply!
Do NOT, NOTNOTNOT touch anything after plugging the power supply like he did.
You will get shocked and you have bad chances of surviving 340V shock.
Please be careful, unlike the dude in the video!
you are absolutely right. the series capacitors hold around 300+ vdc. and there is a bleeder resistor to discharge these capacitors and it takes a few minutes to discharge, sometimes the bleeder resistor is open, in that case we must careful
Please accept my best regards and special thanks for highlighting a critical safety point
fuse ko jumper laga kar desi triqa kar gay ho ap, geniun triqa kia karo.
you are right. lekin ye just for troubleshooting he.
permanent solution keliey kabhi bhi safety ko bypass nhi karna chahiey
meri koi shop nhi he, me ye videos sirf educational purpose keiey share karta hoon ta k kisi ko is se fayeda ho sakey
