Try disconnecting everything (all inputs, outputs and speakers, make sure there is no cable plugged into your unit except the power cord), turn it on, if it still shows the protect message, you have an internal short or a burnt out component inside the unit, possibly a desoldered contact on one of the connectors which generates internal noise of such intensity that it sends the unit into the protect mode.

If, after trying the above mentioned, there's no message, some other possibilities are:

- a bad speaker or speaker cable
- a bad signal interconnection cable
- a fault in any of the other units connected to your reciever/amplifier

Hope you cand find something out...

Good luck

Protector


Look for any bulging on metal capacitors. As they age they can fail, but won't show it until power is stopped for a time. Then when you try to power up the system the fault shows itself Replace all that look that way

My sony receiver STR-DE135 is showing a protector message


Check for shorted speaker cables, or even a bad speaker. I'd start by disconnecting all speakers, see if the indicator goes out. If so, try one speaker at a time until you find which channel is bad, and then examine the cables carefully for things like a stray wire strand. Less likely, but possible is a shorted speaker. If you disconnect them all, and still have the protector circuit on, it's an internal issue, and you're going to need a technician.

I get a message "protector check code 11" and then it powers off


Page 59 of the manual (avaliable at retrevo.com after you register)...

"PROTECTOR/CHECK CODE 11
Irregular current is output from the speakers. Turn off the receiver , check the speaker conenction and turn on power again"

What this means is it senses a short circuit in one or more of the speaker paths. Disconnect all speakers, see if it works with none; then start connecting speakers again until you find the problem.

Message "PROTECTOR"


Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts. If it cuts out, it needs service. If you need detailed troubleshooting help on this after testing receiver without speakers connected and it passes, post a comment and I can walk you thru it. Hope this helps.

MySony str-da5000es is showing error code 11 and shut off by itself after few seconds.check and disconnect all speakers, unplugged power from wall and still showing error 11. am missing something in here...


error code 11 (protector) - According to the manual, 11/PROTECTOR means, "Irregular current is output from the speakers. Turn of the receiver, check the speaker connection and turn on the power again." Most likely, a strand of speaker wire is shorted to the chassis at one of the speaker terminals.
Hope this helps !

check/replace your speaker wires. If a wire came loose, it will go into "protect" mode and shut down, to protect from a short circuit.
