In this case, does it always power up for just a second before shutting down when trying to run it on 110V? Or did it do that just once, and now it's not powering up at all?
If it powers up on 12V, I'd suspect something in the power supply went fault.
Try keying up the radio in your vehicle. If you are able to key up on AM, but do not have any modulated audio, and no receive audio, I'd suspect a bad audio IC.
I forgot all about the relay.
Sometimes the wire retainer has been removed and is no longer present and could allow the relay to wiggle loose in the socket if the radio were to be moved around in different positions such as what might occur if you were to blow the dust out with compressed air.
Sometimes if you exercise them they will start to behave better.
If not then you might have to administer some contact cleaner to the internals of the switches and then give them some exercise.
And unfornately that is some of the woes with older radio equipment.
