Hello, Needing some help with a monitor. Model AV-7TF (KDS 17" Avitron) acts as though it is ready to show an image but doesn't. Checked video card with other monitor (exact model, I have three) and card is fine. Power supply is fine. The monitor acts and sounds as though it's initializing a picture, but never produces one. I am unable to get to the on-screen menu to make any adjustments. LED stays on, doesn't go into suspend mode. One thing I did notice was that the pin configuration on the plug was different than the others. All pins were in except for #9 whereas the others had numbers 4,9 and 11 vacant. Any help would be appreciated.
