I have an Onkyo TX-SR502. We have surround sound in our living room (speakers already in the wall) in a house we just moved in to. Today I tried to hook it up using the speaker wire. I got one speaker hooked up successfully and then BLAMMO..... the receiver powered off. I unhooked the speaker wires and tried turning it back on but it keeps shutting off. The manual says the amp protection system has been activated. What the $***!!! do I do now ?????????

Hello, Since the TX-SR502 does not have HDMI inputs you need to connect the HDMI from the XBox 360 to the TV. You can connect an optical cable from the XBox to the receiver if the XBox has an optical output. If not you can connect the optical out from the TV to the receiver. Connect to the optical #2 port on the receiver and press the video 2 button. You should have audio. Thank you, Onkyo USA
Unfortunately, the RC-771M remote doesn't control the TX-SR502. It will only work with these Onkyo models: TX-NR1008 and TX-NR808. The RC-567M is the one for the TX-SR502; replacement remotes that are exact replacements are still available from various places including Amazon.com .
Since the TX-SR502 was released in ~2004, that replacement remote probably won't control other devices that were released in 2004 or later. Onkyo changed its IR code programming before the TX-NR1008 was released in ~2010 and the RC-771M can't communicate with the older receiver. The manuals for the receivers listed above are still available from Onkyo on the product page under the Downloads tab.
How you power off the amp won't hurt it generally. I used to fix ONKYO amps under warranty, and I can tell you now, it will be full of dry solder joints. Take you unit to your local repairer, and they will resolder all the offending PCB's inside. This type of repair will fix 99% of strange audio noises and cutting in and out etc. for ONKYO recievers. Otherwise this is quite a good product.
you have to verify your connection cause if you are a short circuit in your different output or input the protection mode is on. it's an internal security
first disconnect all your output speakers, and restart your amplifier if the protection mode is on again try to disconnect all your input device and restart your amplifier, the protection mode should be off, so after connect one device after one to check who makes your protection mode on
