Working on a Flight 2000 project. All of my displays are blank minus one. I have moved it around and it continues to work in other player locations but the others do not. The displays look good and there is a "glow" in the corner when the machine is booting up but they remain blank. I saw a link here on pinside that explains how to test the display and it mentioned shorting one of the transistors on a stern display but I cannot find the link anymore. Can anyone help? Thanks.
