You likely have some bad capacitors in the vertical stage still. If you could put a circle pattern up from a generator or dvd, you can adjust for a perfect circle then you will see if the raster will fill the screen. Also check the circuit grounds in the vertical output stage. B+ could be a little low. If it is to low the picture will usually pull in horizontally some. Be sure and check the resistors as well. There may be some that have drifted high in value.
