About 3 weeks ago my Right Front Polk Audio R50 took a great tumble and was knocked over rather hard. AT first it was working fine and everything. However, it started to be spotty and work sometimes, and other times not at all. I attributed it could be the fall. But today my Left Front Polk Audio R50 stopped working. I thought it was weird, and since the wife was the one who knocked over the Right one, I thought she may have switched them so I wouldn't notice the right side not working sometimes. Well, WHen I tried with the connections on the back, it turned off my Onkyo 876. I use Banana plugs for my connections, and have an idea it may be one problem. And now my Onkyo is blinking the Standby light on the front, and won't stay on.

Any ideas?

Also, last night my fuse box got tripped and had to reset the fuse for that section, could that be a possibility? I have a surge protector for the Stereo and rest of the equipment

Have you tried to unplug the receiver from the power and let it sit for about 10 min and plug back in.
disconnect the two front speakers before you plug it back in and see what happens.

I unplugged it for 10 minutes, and than unplugged the main's, at the speaker level, and it still turned off after turning on.

it sounds like a fault and is shutting down. Unplug the receiver again and unhook all the speakers at the receiver end (yes I know this is a pain) plug the receiver back in and try again.

Man, this 876 is so heavy and large that my TV stand has to have it on the bottom shelf...and sticking out like a good 2 inches. getting it out is kinda a pain because i only have about 3 to 4 inches clearance over the onkyo. so i have to pull it nearly completely out, than push the wires back.

So I unplugged it yet again, than disconnected the speakers. After 10 minutes or so, i plugged it back in where it still turned off after i turned it on

Thats not a good sign, You should give Onkyo's customer service a call and see what they say. I suspect something got damaged inside.

I did some searching and it seems that if this happens you may need to unplug everything from the back of the receiver and then power it up again as some other piece of equipment could be causing this issue as well particularly anything using HDMI. The flashing standby light means that it is in "protect mode".
I do think that something is shorting out inside the Polk that got knocked down and that in turn has caused some sort of issue with the 876.

Ha, I did unplug everything from the 876. Even the HDMI out, the inputs, all outs...still nothing.

I sent a note to Onkyo Support. Hopefully I will get a response

Brock, you never mentioned if you're Bi-Amping your two front Polk R50 main speakers?
I see that you are using your system as a 5.1-channel configuration.
