Just picked up an F-14 Tomcat project. I have it working, but there are a few issues to resolve. One is that the player 3 display isn't working at all. The other displays are bright and not outgassed. I'm a bit stumped. I don't see any test points on the back of the display, and I'm not finding much in the way of documentation. Any thoughts on what I could check? I've already reseated all of the cables. I can order a new ribbon cable if that's the likely suspect, but I get *nothing*, not even garbled data, on that display.
Thanks in advance
