I’m having the same problem when I replacing the screen of my SP4 #1704 to SP4 #1796’s, which is LG LP123WQ1. I don’t want to but old Samsung screen because it has flaws. The seller knows my needs and sent me a SP5’s screen including a new connector for LG-screen SP4 model. But now the new screen also not turning on while Microsoft RD can access access the device and digitizer is working. After replacing the screen to the old one which is Samsung LTY123YL01, it works though it’s showing broken image. Looking for people who suffered the same issue.
