Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

It may, unfortunately, have died. Old stereo equipment does do that.

I think that you shoud try this:

1. if you have a voltmeter, set it to Ohms/Resistance, and test across the speaker wires, one pair of wires at a time, to see if any are shorted as opposed to just the resistance of the speakers.

2. if you don't, disconnect all speakers but one, and try turning the device again.

3. if that doesn't work either, turn it Off, disconnect that speaker, connect a different one up (and only one) and try turning it On again...

If that doesn't produce any result, the device is most likely defective in its audio amplifier.

But, also, make sure (in the above tests) that the speakers are selected/activated on the device's controls (if it has speaker selection as a feature, e.g. a 'speaker' switch.)

And check to see if there is a speaker fuse in a transparent holder on the back of the device, also, and whether that looks blown (which is usually quite obvious when it is.)

After that you'll have to assume the device is defective / needs repair, I'm sorry to say if that is how it does turn out.
