The HDD on my iMac failed couple weeks back and yesterday, I opened the screen and replaced the dead HDD with an SSD. Powered on the Mac and reinstalled Catalina using a bootable USB drive. Everything went well and macOS got installed. After first login, the system prompted me that there are updates available that need to be installed, I clicked restart and install the updates. Mac restarted and installing the ~1.2GB update for Catalina and it was about 40% complete that the iMac suddenly turned off.
I tried pressing the power button and turn it back on but it would not turn back on. I unplugged it from the power strip it is plugged into and left it unplugged for an hour. Came back and tried again and it would not boot, no sound, screen would not come on, nothing. Then, I tried resetting the SMC by following the instructions on Apple's site and still nothing.
I tried plugging it into another wall socket and still nothing, I am sure the wall jack works because i plugged something else into it and it works.
I am not sure what else I can do, any help is appreciated.
