Receiver Not Powering On

If your Pioneer SX-218 receiver is not producing any sound or showing any indication of power, despite hearing a clicking sound when you push the power button, there could be a few potential causes for the issue:

1. Power Supply: Verify that the receiver is properly connected to a working power outlet and that the power cable is securely plugged in. Check for any loose connections or damaged power cords. Try plugging the receiver into a different power outlet to eliminate the possibility of a faulty outlet causing the issue.
2. Protection Mode: Some receivers have built-in protection mechanisms that activate in case of a fault or short circuit. This can cause the receiver to shut down and not produce any sound. Check for any obvious issues, such as loose speaker wires or a shorted speaker. Disconnect all speakers and peripherals from the receiver, then power it on to see if it starts up. If it does, gradually reconnect the speakers and peripherals one by one to identify any potential issues.
3. Speaker Impedance: Ensure that the speakers connected to the receiver have the correct impedance rating compatible with the receiver's specifications. Using speakers with impedance levels outside the recommended range can cause the receiver to go into protection mode or produce no sound.
4. Reset the Receiver: Perform a factory reset on the receiver to eliminate any settings-related issues. Refer to the user manual or the manufacturer's website for instructions on how to reset your specific model. Keep in mind that a factory reset will erase any custom settings and configurations, so you may need to set up the receiver again afterward.
5. Internal Component Fault: If none of the above steps resolve the issue, it's possible that there may be an internal component failure in the receiver. In such cases, it is recommended to contact Pioneer customer support or consult a qualified technician for further diagnosis and repair.

Remember to consult the user manual for your Pioneer SX-218 receiver for specific troubleshooting steps and instructions tailored to your model. If you are unsure or uncomfortable performing any troubleshooting steps, it's best to seek professional assistance to avoid causing further damage to the receiver.

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.

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.

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.

HI:
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 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!

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.

Regards.

remove all external devices and speakers
the clicking is the auto protection.

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
