Get a meter and test the red wire for power with the key on, the yellow for constant power and black for ground. If they all test good, the radio is probably done. I have replaced more of those then i've sold.
I had a friend that had one put in a 56 ford wagon, of course I get called when it doesn't work after they paid somebody else to install it. The left **** went bad after a week, luckily I lived close enough to take it back to CA to have it repaired.
