You are very close to getting it to work and we only have to methodically work it through.
Bypassing the RF and IF and feeding the video directly to the video amplifier I do not think is a viable option for you. There is no conventional contrast or gain control and you may have to construct a transistorized gain contolled amplfier to invert the video and ensure the video level is correct. It won't be a matter of directly connecting the video to the grid of the tube. If you cannot diagnose this simple fault do you think you are up to some electronic design and construction work?
I have gone through great pains to outline tests which you have not responded to. Do you understand what I have said about the tuning?
