How to Fix Computer Power Troubleshooting Repair Tips
I have explained how to repair the ATX switching power supply of an SMPS computer very easily. This power supply uses SDC2921 IC which is an intelligent PWM and power monitor. I have shared my simplest and most perfect troubleshooting techniques. smps concept and troubleshooting repair or understanding the basics and working principle of switching power supply. how to troubleshoot input electromagnetic induction filter, EMI, bridge rectifier and capacitor. we get 330 VDC at the main capacitor. after that the +330 volts are applied to the sleep power supply, which is SMPS and is +5V SB, these sleep voltages are applied to the motherboard which lowers the green PS ON wire to zero level, hence the ENABLE pin OR REMOTE ON or CONTROL of #smps will become low, allowing pulse width modulation. and i also discussed the basics of smps. after watching this video you will be able to:-
understand circuit diagram of atx power supply basics with complete tutorial
operation of atx smps
if the computer power does not turn on, or the fan spins and stops, fluctuation, the power turns off again or does not start
short circuit or blown fuse burns again and again
