Fair warning: schematics can have typos, or not reflect the production change revision of the set in front of you, check values labeled on parts against the schematic, and watch for differences.
My first TV restoration burned me that way...It was a '53 Zenith, and the sams listed a different value by a factor of 10 for the cap on the parts list than it did in the schematic. I could not read bee caps at the time (and it was full of them), and replaced them based on what it read on the schematic......It had a no video problem at the time and the typo was on a vertical stage cap. I was between residences in Wi. and Fl. at the time and a couple of years in when I finally got video back I became aware of the problem....The vertical was scanning at 120Hz instead of 60....I had no caps or money at the time (mid way through highschool) to try the other cap value listed, and no clue where the original was so I fixed the issue with decade box engineering.....I connected a resistance decade box in place of several of the resistors until I found a value I could change a resistor to to restore it to 60Hz operation.
I used lousy caps on it then, and did not change them all (since I was bad at parts sourcing back then) so it is almost due for a re-recap....When I get to that I'm going to see if I can re-fix (it has not relapsed) that vertical issue 'right'.
I could give you two or more examples of sams leading me to the wrong move, but I've already rambled plenty.
