{966} SMPS Is not working, not turning on, no output voltage

in this video number {966} SMPS Is Not Working || SMPS Not Turning ON. i explained how to troubleshoot, test and repair KA7500/TL494 based switch mode power supply. this smps controller drives the half bridge topology using D130077 NPN power transistors I replaced it with MJE13007 as equivalent transistor. i found the power transistors and related components damaged, i replaced it and it started working
