Hello friends i have a SMPS https://www.electronicscomp.com/rd-...-8a-12v-4a-88w-dual-output-metal-power-supply
It's working perfectly and suddenly its blast on power supply. So i have opened the SMPS and find out there is a Fuse and NTC is blown and also checking other component but didn't find anything else to burn.I have also checked Diode and all is good.
So i have inserted same rating Fuse and NTC and also change Opto coupler ic PC817 of feedback circuit and then start the SMPS but now problem is SMPS output Green LED is flashing On and Off .
So please suggest me what other to i have a check?
