easy, grab a schematic (helpful but not absolutly nessasary) Start by replacing every wax paper cap. Go slow, one at a time, figure out a way that works for you that marks where it goes so if you get distracted you want goof up. there are all kinds of stratagies on how to replace, as far as pig tailing vs. complete removal from the term strip.
I pig tail when working on delidcate coil form terminals, they break easy and the stress of removal can ruin your day, otherwise I use solder wick on point to point chassis and desolder gun on PCB 's.
Some time you will have several caps going to one place on a term strip, this can be tricky, if you desolder all the caps 1st you end up wiht a bunch of un hooked caps. Just be slow, even pic would help if you camera can get in close.
Since its your 1st time you may want to just do one cap at a time and try it after each one, that way if you goof you know where to look, as opposed to a shot gun replacement of all at once. This also applies to the fact that the tv is somewhat working. I know its a PITA to do one then set it up, but better that than goofing and having to trouble shoot the problem, which can be hard esp if your new at it and dont have the tools to trouble shoot.
other than the paper caps, you can replace the large value electrolytics, which will prob increase at least the vert if the vert osc tube is bypassed with one. With a set that old the filter cans "may" be bad, not always but I would hold off on that until you get the papers done.
again a strategy applies, do you go under the chassis or stuff the cans, I stuff the cans since it keeps the lead dress orig, opinions vary on this, I say do what you prefer, it really makes no diff, just as long as you take the old cap out of the circuit.
with a schematic and perhaps a Sams folder you get voltage checks and resistance measurements at the pin sockets. A helpful tool if you have to trouble shoot, but by no means the gospel.
Good luck with it!!
