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 !!
Sir very good learning videos thank you for all your efforts. I have watched your ATX PS repair previous videos also they are very good. Allah barkat de.
Though many UA-cam 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

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.
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
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?

Sir, My SMPS show only 3.7volt Standby voltage it's has 2N60 mosfet for Standby switch I check MOSFET it's showing all correct reading I replaced opto coupler 817 Check 2 resistor 1k and 10ohms which connects to coupler both ok Replace IC TL431, 222 1kv PF , 471 1kv and check all stand-by components but couldn't find fault still it shows 3.7v please help me to find fault I am always crazy to repair switching Power supply but few 2-3 power supply I found fault. Thanks in advance 👍
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.
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?
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

Superb troubleshooting process
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

Sir,
My SMPS show only 3.7volt Standby voltage it's has 2N60 mosfet for Standby switch
I check MOSFET it's showing all correct reading
I replaced opto coupler 817
Check 2 resistor 1k and 10ohms
which connects to coupler both ok
Replace IC TL431, 222 1kv PF , 471 1kv and check all stand-by components but couldn't find fault still it shows 3.7v please help me to find fault
I am always crazy to repair switching Power supply but few 2-3 power supply I found fault.
