Default Speaker Terminals Short Circuited, Receiver LED Flashing

Hello everyone,

Boy do I ever feel like a idiot, I thought I turned it off!!

I was plugging in a coax digital cable in on the back of my receiver and by mistake pulled the "Red" speaker wire out on the front right speaker, then tried to plug it back in and there was a "loud spark noise" and the receiver shut off abruptly with the power LED blinking rapidly! After unplugging it from the wall for over a hour I turned it back on where the LED blinks until it go's solid to indicate its fully on, once the LED go's solid I should hear sound coming from my speakers. It simply shuts itself off when the LED go's solid and begins blinking rapidly! I don't understand, I didn't touch the red wire to the black one, I just put it back into where it came out from.

Both fuses are fine, did an ohms test on both

If you got a spark, something definitely shorted...

When I went to put the metal covering back on I noticed three small black soot stains above the amp section, there's these circuit boards right on top of the amp section. Hope it's not serious or expensive, I would hate to buy a new AV receiver now when I don't really need one just yet!

Hope you can get that resolved with little or no cost but I doubt it.

I now believe those brown marks are hot spots, whenever I would place my hand on top it felt hot where those marks are when operating normally. The amp section is right there where you see those dusty hot spots. I did learn my lesson this time, it will never happen again!! I'm taking it to a Denon repair facility in October, $50 bucks to diagnosis. I figure if I have to buy a new AV receiver it will cost me $1500-$2000 because I drive a 4 ohms speaker system, if it weren't for that I could settle for a mid end unit.

These days, most of the mid range products handle a 4 Ohm load quite well so I believe the4 cost of replacement will be 1/2 or less than what you predicted.

It is very important that if I need to replace my Denon unit I want "high quality sound" equal to or better than my AVR-5700 THX Ultra Certified receiver! What current Denon model is on par with my AVR-5700 sound quality and what would you consider mid-end?

Thank you Techlord,

How does Marantz stack up against Denon receivers? All I've ever known is Denon and Yamaha receivers.

I would compare Denon and Marantz side by side as pretty much equals (although I prefer the Marantz but not for any technical reason). If you heard one you would fall in love. The 800 series and above in the Onkyo line are quite nice as well.

If I or any other audio professional/engineer had to choose between Denon and Marantz (both owned by D & M Holdings) it would be a very difficult decision because they are both excellent brands, true performers and are a cut above.

I do love the Marantz brushed aluminum faceplate with the touch of golden decals, it really gives it a sexy high end look!

That's the reason I like Marantz better, the looks.

It seems I missed this post, anyway my Denon's temperature sensitive fan rarely ever came on. When I would watch a movie at very very high listening levels where the action was non stop my fan would come on, then when the action would quiet down I heard my fan running. I would usually hear it turn off almost right away. I have heard a lot of complaints (over at AVS forum) about Denon receivers with HDMI inputs that have a problem with video and audio freeze ups, seen it demonstrated on YouTube, what is your take on the complaints?

Thank you Techlord,
