1988 VMC 40 Video/Control Issues

[easternmachine]

I recently aquired a 1988 VMC 40, the machine was stored for approx. 6 mo. with no power. I have the machine installed and have run into a problem with the monitor not displaying any information. I can turn the video switch off and a green line shows and ends in small green dot in the center. I have tried reseating the 1420-1 video card and checked the video cable connection. I contacted Flint and they think it could be the video card or the 1400-2 cpu board. The machine control does not boot up, I have checked the 5 volt power and I get the flashing red lcd lights. Is there any way to test the video card other than swapping with a new one? Is this machine limited to using the 1420-1 or will a newer version work? Thanks.

GET AN OLD TV SET WITH RC PLUGS, THE BLACK COAXIL CABLE THAT PLUGS IN TO THE MONITOR, PLUG IT TO THE TV VIDEO IN. iF THE CONNECTO OF THE MONITOR IS DIFERENT, GO TO RADIO SHACK OR FRY'S TO GET A CONVERTER FOR A FEW $$.
