If it is the same as your avatar then I believe it is a 1963 model.
Doing a 5 tube radio first is good to get a feel for electronics on a much simpler device.
Have you adjusted the fine tuning knob? Best picture and best sound don't always line up. Try adjusting fine tuning for best picture. The fine tuning knob is often concentric (the rear one on the shaft) with the channel tuning. Channel tuning will click, fine tuning will smoothly turn. Sometimes setting the VCR to an adjacent channel, or the TV to an adjacent channel will get beter signal.
The capacitors (electrolytic and paper) are dead or dying, and need to be replaced....Especially those in the vertical circuit (which is why there is no light at the bottom of the screen).
You will want to get a copy of the set's schematic....If it is a Canadian made model that may be hard as the major sources did not completely cover Canadian sets.
VCRs are not the best signal sources for TVs made prior to 1980....VCRs have VERY crappy synch timing (since the mechanics effect it, and the mechanics are rarely close enough to ideal). Sets not made to deal with VCRs will often have the top of the image pulled to one side, and straight vertical lines appear as zig-zags...
