Here are your options:

1. An electrical problem, where your receiver has a grounding problem.
2. Your speaker wire connections are actually touching each other and that's why your receiver is not turning on.

SOURCE: Powered Or Unpowered Subwoofers For Onkyo TX-8511

Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

SOURCE: how powerful loudspeakers can my Onkyo TX-SV444 tackle, maintaining good sound?

buy 6ohms or 8 ohms speakers. 4ohms consume too much power and sometimes causes short circuit. (safety first!)

I am experiencing issues like this although with a VCR connected with analog video. I added a BluRay DVD player and all of a sudden I lost my video upconversion from my VCR. I am going to try to reset the receiver to see if this fixes the problem. If not, I don't think it is the receiver issue, I think it may be the fact that enorder for video to pass through HDMI, allot of criteria needs to be met. Certain Handshakes need to happen, especially with the HDCP issues. Most likely I will connect a separate video cable to my Plasma and use a secondary input on the Plasma for the VCR signal. You may want to purchase the Component Video adapter for the wii system as this will provide you with at least 480p and your receiver should not have an issue passing the signal over the HDMI output. Good luck and give me an update.
