Receiver Not Powering On

I connect the power cord to my previously working receiver and no lights come on. All I hear is a clicking noise that sounds like relays opening and closing over and over again.

What could the problem be? I have already removed ALL connections from the back of the receiver.

Hello: I would like to know if you could tell me if there is a way to get this receiver to work again. As it does not turn on when powering it up.

It sounds like the power supply has gone out on it, I am having no luck in finding a replacement part for you though, sorry.

Whwn I switch on the system and even when the sound is ZERO. there is a hissing/humming noise from all the speakers. Not sure whay this sound is there.

It is noise most often referred to as E.M.I. or R.F.I. ( electromagnetic or radio frequency interference). Sources of it can come from other devices plugged into the same circuitry or from nearby running appliances containing electric motors such as fans, or fluorescent lighting.

Things that you can do to reduce this are as follows;

Relocate the receiver and/or plug it into a different outlet.

Plug the receiver into an electronic interference rejecting device such as a power conditioner.

Use ferrite clamps on your power cord of the receiver and all of it's connected devices, and on the analog audio inputs.

Move any power cables closer than about 6" to any other cables connected to the receiver, and any cables crossing each other at 90 degrees.

Make sure all of your RCA, composite and coaxial connections are completely inserted on each end and tight.

When you plugged it in the first time the massive difference in voltage has purely and simply fried the power source. The entire power source has been destroyed and will have to be completely rebuilt or replaced - and pray to all your gods that nothing else has been damaged.
The fact that you have installed the wrong converter didn't helped , you just burned more from the power source, extending the damage even further. Everything else you witness is the result of the damage.
First of all send your receiver to be repaired - i can tell you from now that it will be very expensive. Then buy a new converter, one with the same voltages but which is capable of handling more than 1.5 KWatts of power, the one you have now is so small that it would have been instantly fried if you have tried to use it . Finally make sure the power lines and the wall socket can handle the power drain, you don't want to overheat a wire and set fire to your house.

In the receiver there is a ampere ic.Its located on the inner circuit board of the receiver.Its got short and faulty.And also the noise which you are hearing again n again this noise is coming from other components on the receiver board getting short.Dont connect it to the power source it will get damaged.First get it repaired by replacing the IC.Also now you have tried and connected the receiver to power source so this might have damage some more electrical components on the board.So all this components has to be replaced.As it will not be very costly repair to get this components replaced.All the required components are easily available at local hardware stores dealing in electrical parts and components.If you are familiar with doing soldering jobs and if you have experience of using multimeter then instead of going to technician you can repair this problem your self by replacing the component. also to disassemble the unit you require a screw driver ands thin knife to un-clip the internal hidden clips. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Well seems the unit is going into protect mode, if you open the unit and look near where the cord enters the unit you will see some fuses, you may of blown one of them. The real problem you might have is a defective power supply, by connecting 240 volts means that while the unit was working all the voltages were out of tolerence or to high in the reciever. There should hear two clicks, one from the power on relay and the second one is the Speaker output relay. Disconnect all speakers from the unit and then try turning on again, if it goes into protect again and the fuses the you may of blown one of the Amplifiers outputs..GOOD LUCK!

The receiver turns on riefly and then makes a

The clicking noise is the protection circuit., sounds like you have a grounded speaker wire, but you say the speakers are not connected so the amp may be toast. Is there any smell of burnt wires? This is ussuallt noticable near the circuit board if something failed!

Protect mode shuts down the receiver

If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Won't Power On...

Hello degaff, This is what I would do to try to determine the problem: 1. Disconnect everything from the receiver. The only thing connected should be the power cord. Make sure the power cord is disconnected from power for at least 30 minutes in order to reset the internal electronic software. 2. Then, power it up - still nothing else connected. If it powers up normally and "looks" like it is going to work, then turn it off and connect only the right speaker to its amplifier and try again. If it still looks normal, then turn it off and connect the DVD or CD player and run some music through that speaker. If it still looks normal, then shut it off and connect the left speaker, etc... In other words go one-by-one in checking it out. 3. If it does NOT power up after step ONE, then there is a problem internally. If it powers up only to shut down again, there is still a hardware problem internally. The usual cause is shorted output transistors. And the normal cause of shorted outputs is a short on the speaker line, a short inside one of the speakers or overdriving the amplifier for too long a period of time. If the outputs need replaced, then it will cost an arm and a leg to get them repaired, and you are better off replacing the unit. The clicking sound, by the way, is the power relay which turns the power transformer on. And if there are faults in the amp, speakers or wiring, the protection circuit shuts the relay off; that is the clicking sound you hear. Please let us know how this works, and if we can help you any further. Best regards, nightdiver
