I used to have a console with that chassis. Go after the whitened resistors first....When they turn white they are shot, and the set will not work properly with them that way.
Sam's is prone to errors, and often did not record production changes. If wiring looks stock get all parts in the circuit tested and on spec first, then if that fails note now it was wired when it came to you (so you can go back if needed) then make it match the schematic...Don't mess with the video/contrast till you have vertical sweep.
The tuners in these can get monstrously dirty, clean it well once you try to get signal through it. IIIRC I lifted a channel strip out and used it to hold a rag soaked in contact cleaner to the drum and rotated the drum till that rag got the hidden fixed contacts clean.
