Hello Shep,
The lenses have these ribbon cables that because of age, seem to detach themselves to the main optic chip. This is due, because they're glued on, rather than soldered on. If you can find someone or have a steady hand, you can carefully solder the ribbon cables to these chips back on. This will bring back the screen back to the lenses. http://www.projectvb.com/tech/displayfix/aftersolder.jpg
