the protected mode kicks in when there is a safety issue with the receiver. This
usually comes from an overload to the system via a short in the system
or perhaps a surge in power. Your receiver shuts down, and you'll need
to shut the entire system down to fix it. In some older homes, some of the wiring doesn't deliver the "cleanest"
power, delivering minor power surges to the items you plug directly into
the wall. If your receiver is plugged directly into the wall, purchase a
surge protector to stop this Read more: http://www.ehow.com/about_5516888_problem-sony-receiver-protected-mode.html#ixzz2ZYa9W0Mi God bless you
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.
The unit will need to be repaired by a technician. Most likely you have a bad transistor that is causing the protect mode to turn on. The only way to get the protect mode to turn off is to remove the bad part.
Disconnect all speakers at the receiver, if it stays on, post a comment and I can help you troubleshoot further. If it stays in "protect" it needs serviced. Hope this helps.

When these units go into protect mode, they normally have a blown channel. It is not an easy fix, it will require the replacement of a few parts. You would need a multimeter and soldering equipment to determain which parts need to be replaced.
If you would like to fix it yourself let me know and I can help you with it, but it would not be an easy job for you unless you have some experience at troubleshooting electronics.
Usually, protect mode is enabled when the speaker output wiring has shorted together or is touching ground/+12V. I would verify that none of the speaker wiring has come loose.
There is a problem with one or both of the audio amplification circuits. The amp is going into "protect mode" to protect your speakers. I'm afraid there is no simple fix. this will need to go to the shop to be repaired...
...unless you have been tinkering with the speaker connections recently. In which case, make sure all connections are sound & there are no wires touching other wires. This causes a short circuit. Leave it disconnected from the mains overnight. There's a slim chance it might spring back to life tomorrow.
