Hi Al, and all the best for the new year.  Have you considered it might be the display panel? Try disconnecting separately each T-con flexie lead to
the panel. If one lead off gives you half a picture or white screen, but the other lead results in a black screen, then the panel is toast. This is mere speculation of course, but at no previous time have I come across so many duff panels.
