Sounds normal if it's a transient 'crackle' lasting a second or two. As the High (positive) Voltage inside the CRT drops rapidly to zero, a negative-going charge is coupled capacitively to the outside of the CRT glass.

Again, normal if the crackle lasts only a second or two. As the HV comes up, a positive-going charge is coupled capacitively to the outside of the CRT glass.
If the hiss/crackle continues while the set is running, that would indicate a problem.
