White screen and no booting. Switched Fusion Drive to SSD. No Change
White screen with no apple logo. I installed an ifixit SSD Micron 1000 GB. Installed into the iMac after loading OSX Catalina onto the SSD. Still white screen even after doing PRAM reset. Not sure if there’s also a problem with Video Card or motherboard. Asking for help.

@jake1776 - Just to make sure we understand things: Your system had a White screen before you altered things - Correct?

Yes, white screen was before I changed to SSD. Before computer went to white screen with no logo, it was almost booting up and getting like half way though the boot up with Apple logo. Occasionally, it would boot in completely and that may be by pressing PRAM reset and other key codes like 30 times. eventually I could never boot in. By then, it was only a white screen. I pre-loaded SAS with Catalina, we are still at a white screen. I removed the SSD several times and tested it again by plugging it into my other 27" iMac (2015 model) and sure enough, it is working and has Catalina OSX working on it. I put it back into my late 2012 iMac. still a white screen. Is there another part I need?
If you think I can't fix it, can I trade the 1TB SSD for a 2TB SSD so that I can still use these parts on my 2015 iMac. (I figure if I can't get the 2012 iMac working, maybe I just use it for spare parts if the 2015 ever breaks and go ahead and take this time to swap the 2TB fusion HDD with a 2TB SSD.
