I recently hooked up an Onkyo TX-SR605 receiver hooked up to five speakers and a subwoofer. (The speakers and subwoofer are also Onkyo from an older HTIB system: skc-100, skf-100, skm-100, skw-100, etc.) Sources are a Panasonic BD-10A, Toshiba HD-A3, and older Sony DVD/VCR combo. I hooked the hi-def players up to the receiver via HDMI and the receiver to the tv via an HDMI-to-DVI cable.
At any rate, the system worked fine for about a month, but the other night the receiver would turn off just seconds after being powered up. A check in the manual tells me that if the receiver "turns off as soon as it's turned on" then "the amp protection circuit has been activated". The only suggestion is to contact my Onkyo dealer or service center immediately.
The receiver won't stay on even after I disconnected all speaker wire and other connectors. I can't think of any particular triggering event. The last time we used the system everything played fine. No other components in the system show any sign of damage. I hooked everything back up to the old receiver (also an Onkyo) and all the speakers seem fine. We weren't running the speakers at max volume or anything either.
I called Onkyo and their best recommendation is to ship it to the service center (they'll cover shipping back to me but not shipping to them). While we've only been using the receiver consistently for a month, we've owned it for more like three months, so there's no real hope of exchanging it at the store. Before I send the receiver off to Colorado (their closest service center to northern California), I though I'd ask if anyone had any other suggestions? Anything else I should try? There doesn't seem to be any way to reset the protection switch to see if it gets tripped again or just works fine.
Thanks in advance...
