Es vs estar

Question

In the case of the broken radio, using 'es' suggests the radio is irreparable, whereas 'está' suggests it can be repaired

Answer

Hola MarcEven if the radio is irreparable, you still use "está estropeada" (not es estropeada) as it's talking about a physical condition and a result. The fact that it may not be possible to fix it doesn't really matter. When we use "ser" with adjectives we express an essential characteristic of something or someone: "yo soy alta" (I may shrink a bit when I get older, but that doesn't matter, being tall is one of my essential physical characteristics, hence "soy") Saludos cordiales
