I'd be more than happy to help you diagnose it if you'd like. If the raster still fills the screen horizontally, it may just need the pin amplitude adjusted like mine did. Common. I also had to change out a couple of open capacitors but it was still an easy fix.
If the picture is shrunken horizontally you should look at the horiz drive voltages and see if your HV is at the proper level to rule out the flyback. I've seen a 70s Sony with short width and it was caused by the horiz linearity control. Some sets do not even have that control though.
