Re: my sony receiver will turn on but not work
This "protection" mechanism is causing your speakers to go silent. Check the back of your receiver for loose/disconnected or shorted wires. Your receiver may have a TEST button that will tell you whether there's a problem with your connections. After having checked/reconnected all speaker wires, run the test by pressing the button. Sound will come from each of the speakers, usually clockwise and go round all speakers until you press the button again. Should there be a problem, the display will tell you whether the polarity is wrong, there's no connection, etc. If the messages don't make sense to you, go to your user's manual for an explanation. Good luck!

Your Protection System probaly come on for some reason,Sony Is Known for that problem, Check on your screen if a red lit warning Staying (protect) Is on.If there is, Try hiting the reciever on the sides or the top of the cover fairly hard when it is turned on, Some times this will work to turn the protect light back off, Sony is bad for there amps end recievers going into the protect mode,
Hi, Check speaker wires, any wire seems shorted and causing Protect Unplug error message in receiver. Good way to sort out bad wire is plug one speaker at a time, turn On receiver check, turn Off, then plug next speaker wire until you find out what speaker wire activates protection circuit of receiver. Thanks.
First thing I'd do is unplug it from the mains and check every speaker connection for short circuits (wires touching) Alternatively, disconnect all speakers and plug in a set of headphones to see if the Protect goes away. Check all components plugged into the receiver by unplugging then one by one. Finally if the Protect is still alight disconnect absolutely everything with the receiver volume control on zero. pull the plug out of the wall and let the receiver sit there for an hour with nothing connected. Then plug it back in plug in your headphones switch the receiver to FM and see what happens. If the protect is still there then I'm afraid the repair shop is your next stop.
BUT check those speaker wires especially if you have puppies or small dogs or believe it or not a small child. They tend to chew on things when teething.
This generally means that you've got a short somewhere. You most likely *don't* need to bring it in for repair.
If you're familiar with how your system's set up, do the following:
1) Unplug the receiver from the wall.
2) Unplug your gear from the receiver
3) Plug the receiver back in
4) Plug each individual component into the receiver, and test it as you go.
The "protect" is there to protect you from damaging your system, which is why it still works (sort of.)
If that solution doesn't work, check all your speaker connections. One may have come loose, and you've got positive and negative connections touching each other.
Protet mode is a special diagnostic mode that starts when a fault is detected.
When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.
Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.
Try unplugging power cable for one hour or so. then connect cable back
and see if you get rid of protect state. Sometimes accumulation of
electrostatic charges inside circuit capacitors can kick in protect
mode. In that case unplugging the unit from main for some times can get
rid of electrostatic charges, and reset circuits by draining power
If that was the problem, you will not get Protect when plugging back power cable.
If you do all the above and still get Protect, then there is a real fault.
In that case the unit may be disassembled and tested to find the fault.
If that is the case I suggest contacting the manufacturer at the number
listed on the owners manual, or asking a quote on repair to a local
Have you connected an extra pair of speakers?. (Thereby loading the amp stage beyond it's capacity)
Are the speakers connected to the unit the original ones the system came with or different? ( Speaker impedance, usually displayed at the back of the speaker cabinet must not be less than amp's specifications....6 ohms, 8 ohms)
If you're driving the unit excessively you're lucky this piece is equipped with protect mode, else your speakers and amp would have been fried by now.
One last possibility comes to mind: High volume causes vibration causing loosely fitted mains plug to rattle in wall socket calling "protect" due to improper feed voltage. Move the unit to another wall socket and ensure a tight fit into mains receptacle.
