I would try and get a picture on the screen, then replace any suspect capacitors, but do these one at a time and check the results after each replacement, then you will know if theres a problem it will be the component you replaced last.
Most of the US, old TV collectors websites always warn about trying old sets before restoration. I'm in this hobby for several years now and the only way to tell the extent of repairs needed is to try it. OF course, my first tryout is to use a series lamp limiter to detect a real serious in the power supply.
Then, I use a signal source after seeing somekind of an image on the screen. My restorations are always done in stages.
