Parasound JC-1s Not Working

I just bought a pair of used JC-1s on Audiogon. The amps sounded fine until I was shuting down my preamp. My preamp is a tube linestage. While I was turning off the linestage, I heard some funny noise from both amps. Feeling uncomfortable about the noise, I turned the linestage back on. Surprisingly, the left channel amp did not work. The power was on but no signal.

I don't think it was the fuse. I swapped the external fuses between the two monoblocks. But it still did not work.

I wonder if this ever happens to you, JC-1s owners. Is there a switch or something inside the amp to reset? I flipped all the swithces on the back panel hoping that I could get the signal back. Still no use.

I am going to call Parasound on Monday. I know I won't have warranty since this is used. But before I call, do you folks have any suggestions? Thanks.

despite the test at radioshack(I wouldn't rely on it anyway), I would still replace the fuses. Sometimes the fuse is blown right under the metal cap and you can't see it. Sometimes when the fuse blows it welds itself together again.
It's only few dollars....replace them before sending the amps to the factory.
