So, I received the replacement logic board today, installed it, and now the iMac starts up as expected.  I still have a video problem, but that is because the replacement LCD screen I ordered is bad.  At least the old one still works now, multi lines and all.  So somehow I must have injured the logic board when I originally installed the replacement LCD screen.  I am definitely more careful handling all the parts now.  Learned a bit about troubleshooting iMacs, so thanks again for all the communications.  Guess I'll close this post.  Thanks.  Ron
