CapZark Posted August 31, 2010 Share Posted August 31, 2010 Here's one for you - my Pioneer reciever keeps tripping its protection circuit, so I disconnected everything and it still trips even at zero volumn. The watt meters bounce up and down a few times and then she goes. Once it warms up things get a lot better, but it still trips from time to time. Any idea what's going on from the techies out there?

CECAA850 Posted August 31, 2010 Share Posted August 31, 2010 If it trips with no speaker wires attatched, it must be in the receiver itself. Is there a way to do a manual reset? Quote Link to comment Share on other sites More sharing options...

fini Posted August 31, 2010 Share Posted August 31, 2010 Yep, I never bend over...Oops, you said don't go there...[] Sorry, now back to the subject at hand... Quote Link to comment Share on other sites More sharing options...
thebes Posted August 31, 2010 Share Posted August 31, 2010 I'd hook up the receiver wires as a minimum. My Denon AV will trip without proper speaker connections. Quote Link to comment Share on other sites More sharing options...
Guest " " Posted August 31, 2010 Share Posted August 31, 2010 how do you turn it off.....are you using a switch on a power strip or power panel...or are you using the power switch on the unit itself. Quote Link to comment Share on other sites More sharing options...
CapZark Posted August 31, 2010 Author Share Posted August 31, 2010 No manual reset, but if you pull the connectors between the amp and pre-amp sections in the back the watt meters stop bouncing around and the problem subsides. I have the unit plugged into a surge protector ($50 model) and first I turn the surge protector on and then the receiver. I reverse the process when I'm done listening. It did cross my mind that maybe I wasn't getting good clean power from the surge protector. The only thing I haven't tried is by passing it. This thing is a relic from the late seventies (Pioneer SX-1980). It's a great intrgrated package, but a bit fickle in it's old age. Intermittent problems come and go, but the tripping seems to keep flashing back[] Quote Link to comment Share on other sites More sharing options...
Guest " " Posted August 31, 2010 Share Posted August 31, 2010 "and first I turn the surge protector on and then the receiver." this is a no go these unit have components in them that prevent cold starts ...typically it's a capacitor across the power switch. you are basically causing surges and spikes the warming circuit keeps the capacitors formed Quote Link to comment Share on other sites More sharing options...
CapZark Posted August 31, 2010 Author Share Posted August 31, 2010 this is a no go these unit have components in them that prevent cold starts So what do I need to do - leave the surge protector on all the time and just switch the unit on and off from power switch? I got in the habit of turning the surge protector off to shut down my sub-woofer which is behind some other stuff. When you say "cold starts" is that why the problem seems to go away after the system warms up or I pull the plug between the amp and pre-amp? In essence clearing the the capacitor of the excess power or spikes? Sorry if I seem novice, but this is true. I don't understand the interworkings of electronics too well, but if leaving the surge protector on solves my problem you've made my day.

CECAA850 Posted September 1, 2010 Share Posted September 1, 2010 I don't know how much stuff you've got on your power strip, but I'd put the sub on a different circuit. Quote Link to comment Share on other sites More sharing options...
CapZark Posted September 1, 2010 Author Share Posted September 1, 2010 Thanks, I'll try that too. Right now everything I own is going through one surge on a 20 amp circuit. Quote Link to comment Share on other sites More sharing options...
Southern Posted September 1, 2010 Share Posted September 1, 2010 This thing is a relic from the late seventies (Pioneer SX-1980). It's a great intrgrated package, but a bit fickle in it's old age. Your receiver is over 30 years old. Chances the caps in the protection circuit may need replacing along with adjusting the DC balance and idle current of the power amp. I suggest you post in the Pioneer Audio section of AudioKarma, very knowledgeable people over there: http://www.audiokarma.org/forums/index.php BTW I still use my SX-1980 and still love it.

CapZark Posted September 3, 2010 Author Share Posted September 3, 2010 Update - I'm leaving the surger protector on and the reciever is not tripping. Fritz may be a genius. Quote Link to comment Share on other sites More sharing options...
