First, you should consider yourself lucky that it did not go up in smoke when it was powered on, normally for something like this, it's brought up very slowly via dim bulb or a variac, but if you got sound, it means power is working to some degree, and this is a good start.
This set is not a hot or floating chassis type, so you are safe there, it has 2 LV rectifiers off the main transformer. Normally the first step would be to replace the electrolytic capacitors in the power supply, and then all the paper capacitors, (there will be a lot of them), and then check for bad resistors. There is a ¼ watt fuse that protects the flyback transformer, if by chance the horizontal oscillator failed to start, the horizontal output would have overloaded and blown this fuse to protect the flyback. Take a close look at it also, is seems this set has a 16KP4, magnetic focus with an ion trap, pay close attention to the position of the items on the neck of the CRT if you take them off, so you can put them back in the same place!
