Well , you don't need a schematic to know what is written on an electrolytic capacitor. If you already know which part is at fault , if you know how to solder, this shouldn't be a problem for you.
Personally, I only need a diagram if I do not know the problem of a particular brand or if the brand of a device has recurring problems. Otherwise I only change the capacitors of the missing part (if I know it's from there) otherwise, yes you will need a schematic.
