yeah I am running through a RF converter out to channel 4... we get beautiful audio but no video. When disconnected fromn the RF source, I can hear snow, I just cant see snow. So I'm thinking somewhere along the way it's losing the video signal?? How do I trace down the video signal?

messed with the fine tuning I presume? just need to cover the basics.

I would look at the video amp tube, maybe an open plate load resistor however with out a schematic its hard to tell exactly where to start.

if you have a scope you would need to trace the signal at the output of the video detector, looking for a composite video signal.
