In this video number {1123A} Why SMPS no output, Why Tik Tik sounds? I explained what was the reason when smps delta smps was not turning on / not working / no output voltage. it was due to MOV varistor CNR14D471K short circuit due to high volatge strikes or swelled line voltage, which caused to blow away fuse. i found smoothing capacitor with increased ESR which is the main reason to failing to hold charge. this was the basic reason for rebooting effect making tik tik sounds
