marantz SR5000 clicks but makes no sound

[srinath]

I have a marantz sr5000 Home theater amp that when you power it on a few seconds later gives off a nice click and no sound comes out of it.
Now my Marantz SR580 - a similar 95-96 HT amp that works perfect does not make that click. Of course it makes sound just fine. So is marantz of that design somehow backwards, and click = bad.

Anyway could someone point me in the right direction. Is there a way to reset the amp ?

Thanks.

This is weird, It had no radio reception, thought it would pull in static, nope.
Anyway this receiver worked great yesterday. for a few mins of test running with a cd player.
Then I connected it on my desk, where at random, at a random time interval after being turned on, it will throw a "protect" and stop making any sound.
Turn it off, then wait a while turn it back on and it repeats that process.
Could anyone point me in the right direction ?
Thanks.

Can an amp go into protect mode for no reason ? because I haven't touched it from when I set it on my desk yesterday. It has been working for 90 mins or so with out going to "protect" mode. Cannot explain that without using the word "juju" ... man that amp got some funky juju ... yea that's about it.
Thanks.

This amp went to protect mode again. I was playing boston "more than a feeling" and was ~20 seconds in. I was running a ribbon tweeter bought off fleabay, a dc300 and a mid I cant remember - I think its a dayton too, anyway, in a fisher st740 cabinet. Now yes it can cause it to go to protect by being low impedance, but this amp has done the protect thing without a speaker connected.
I powered it off. 5 seconds later powered it back on and it started working again like nothing happened.
So is it a known design flaw ? does it hate speakers that vary in pmpedance. Should I run it only on true 8 ohm speakers.
Thanks in advance.
