You've blown it. It recognizes a potentally harmful situation and goes into protect mode.

this is not a reset problem, you have a defective audio output, is either the outputs transistors or the drivers IC's ( integrated circuit) and sometimes if you are lucky is just loose connections on the drivers IC;s.
good luck

SOURCE: Sony STR-GX800ES receiver "protector" blinking - no sound

The most common problem found on FixYa for Audio Video2_bing.gif Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

SOURCE: Sony STR-K670P Surround Reciever. No output from

This is a common problem that a lot of people have with this system. The problem is in the connection of the Left and Right Speakers to the receiver. I had this problem too.
What you need to do is actually open up the receiver using a screwdriver. Once it is opened up you will see a circuit board and lots of wires. Look for the red and blue wire that should be pretty easily visible. Cut each one, then strip the ends some, and reattach the ends but to the opposite color- make sure to solder it as well. On some models they messed up the connections and it got switched. Once you do this, the left and right speakers should work great. Hope this helped!!

5.1 Surround sound not working


Maybe the surround processor is having a bad day... My kenwood would do similar and a reset was necessary to correct. Have you tried resetting the system? On my Sony STR DE 597 this is accomplished by powering off. Then while holding the 2 channel button down (front face plate) power on. A reset message is displayed. Your model may be similar but check your manual or download the PDF of the manual from Sony's support website. Hope this helps

Fuzzy sound from right front speaker output


The main issue is to determine where the distortion is coming from. Does it start in the front and and get amplified or does it appear in the output section only? This will require a fixed signal and an oscilloscope to trace. Check for leaky coupling caps or leaky transistors in at the diff-amp section.

Surround sound distortion


Receivers like this will incorrectly decode rear channel audio and pass it on to the rear channels as distorted audio. Make sure the source being used really has rear channel information encoded into it. It could have other issues but check this first.
