Brenda what do you think the fine horizontal lines are from.
From the schematic I see the video output tube is with the CRT. Without an oscilloscope don't know how one would troubleshoot. You can't see what the video signal looks like without one. Did this tube get tested? I see at least three caps in the CRT housing?
One might be able to substitute a piece of RG59 or RG6 TV cable for the video going to the CRT. I sure the impendence is not correct but if it's short enough it should work for testing.
