5V present at green wire, no 12V and no 3V present. When this green pin is grounded then SMPS fan starts for a moment only. What may be the falt and Which component should I check?
Without 12v others volt like 3 3v 5v are here then you can cheak after main transformer circuit like- polarize capasitor, solder spot of wire, resistor. thankyou
Hi ,I have test my atx12v SMPS output values with multimeter on no-load the voltages +12v,+3.3vdc ,+5vdc are correct but voltage between blue and black wire is -9.6Vdc (rated voltage -12vdc ) So this low voltage can be a reason for no input signal on monitor ? and how can I fix my SMPS ?
Is is feature of smps. You check the feature of your smps for details. Basically smps gave +12,+3.3,+5,-12 DC etc. So smps gave negative voltage (-9,-12 DC) for our working purpose. Thank you
Smps dc output current, when you connect a load in output the load need some current. In this time you increase the load then the current increase. output voltage stable but output current increase/ decrease depending on load.
Resp Sir! Good Morning Sir. Sir One Customer bring the HP 300W SMPS SB Missing Sir, TNY277PN IC No Short, MFC is 335 DC OK Sir, VCC Capacitors are all OK Sir, Near MFC T2D04 Diode on board 10Ohms Value Beep Sound Sir, that Diode Removed and Tested No Beep Sir, 2Side Diode Mode Tested No Value Desplayed Sir and Onother Diode Replaced again Beepsound with 10Ohms Sir, where the Problem Sir.

Good mix of theory and practical work. Worked hard in drawing circuit diagram. Well done...!!!
thankyou
Great effort 👍 very good.
Bohot modot mili is video se
Only useful video for me, on the RUclips .
Terimakasih pak telah berbagi skematik SMPS ATX SD6109. ijin download
sir, after short circuit, smps no output 12v. problem. 5v output ok. kya problem ho sakta?
Yeh 240 Dc volt se operate hoga kya
thanks❤
Diode value which come after main transformer
I don't understand
Which diod you call zoner that is in4148 and
5V present at green wire, no 12V and no 3V present.
When this green pin is grounded then SMPS fan starts for a moment only. What may be the falt and
Which component should I check?
I made a video for this quarry.thanku
@@technicalpresentation9660 please share the link.
Thank You
My smps have +5v at green also have stand by 5v but when i short green and black wire i have no 12v where can be the problem please help
Without 12v others volt like 3
3v 5v are here then you can cheak after main transformer circuit like- polarize capasitor, solder spot of wire, resistor.
thankyou
@@technicalpresentation9660 ok thanks
Did you draw the circuit diagram from the PCB layout or from specifications?
Will be try?

@@technicalpresentation9660 thanks for concern ,later tested smps under load Now tested voltage is -12vdc(rated voltage)
Thank you very much for your diagram and scheme
But you not illustrated 110v switch
Rectifier ke liye 2diode RL207 ka or 2diode 1N4007 ka use kr skte h kya sir ...?
hoga but 4 diode agar ek no ki lagai to acha hoga.
1n4007 diode 1 A ka ha.
RL206 diode 2 ka ha
@@technicalpresentation9660 thank you so much sir
what is the output current
Smps dc output current, when you connect a load in output the load need some current. In this time you increase the load then the current increase. output voltage stable but output current increase/ decrease depending on load.
Capacitor heating problem
Sir, could STR module can use in computer smps (500w) for stand by voltage???
Don't use
give me the bom of 240w smps with circuit diagram
Ok. I try
sir -12 volt or 3.3volt nahi ban rahe ,corsair ka smps he
Primary section section main 5 v cheak kigiye
5v not present, what should i check?
Pls Check standby transformer
Pls check standby transformer
Driver transformer on karne ke liye jo 2 transistor kaise Kam karta he please explain kijiye
ok i explain later
Driver transformer on off thoda details me boliye please
ok

Which you call zener all are in4148 not zena
Plz draw diagram with pen 🖊️
Ok I made it latter
Diagram ok hay
Ha
My ATX 500 Watts restarts every 5 min
Plz, check smps secondary part. And follow my previous smps(repair) video
Not a detailed. Just overall a quick review
Lod lagate hi supply band ho jati hy is ko theek kaise ksren
primary section cheak kariye
