Receiver shuts down after a message


I have a Sony STR DA2000ES that I bought used a couple weeks ago. Yesterday when I was wiring up the center speaker for the first time, I neglected to turn off the receiver. I heard a pop when I put the wire in the terminal and the receiver shut off. When I power it up, 'protector' flashes and then 'message 11' flashes and it shuts off. I've checked for any stray speaker wire and also have disconnected all speakers and inputs and left the machine unplugged over night. The receiver will still not power up normally. Is there anything I can try before having to take it to the shop?

Thanks

Any tips on where to look for the fuse(s)? I took the shell off but did not see any fuses in easy to see locations.

Thanks.
My guess is a protection circuit was triggered and needs to be reset. I read the following post on another forum, which I have copied below:

"I saw this problem from a Sony ES receiver after I...ahem...shorted out one of the speaker leads while it was playing. It would start turning on, and then when the relays would normally kick on the speakers, it would shut down flashing the Protected message. There was a 'factory' reset procedure that a tech walked me through, but it didn't work. I can't remember the key sequence either."

While it doesn't provide an actual answer to your question, this quote suggests you should call a Sony tech to try the reset procedure. Or, perhaps it wouldn't be so expensive to take it into a service lab if all they need to do is walk through the appropriate reset procedure. (Maybe somebody on Audiogon knows the procedure?) Good luck.
If you have the manual for the receiver, it will probably list the steps required to perform a "reset to factory defaults". Give that a try. If you don't have the manual, do a google search. Sony typically has their manuals available on-line.

I looked it up on-line.

Turn unit off. Then press and hold the power on button for 5 second or more. "Enter to clear" will display on the front panel. While it is displayed, press the enter key on front of the receiver.

I tried the 'enter to clear' process but after the 'memory clearing' message displays, it still flashes 'protector' then 'message 11' and powers off.
