Pioneer VSX-53TX Receiver Questions & Answers
Power shuts down
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as another possible root cause forintermittent shutdown.

hi,
First of all remove all the speaker connections from the amplifier. After that power the amplifier and check the protect show or not . if not, then any of the speaker is damaged. If then also it shows protect you have to check the amplifiers hardware.
AV receivers shows protect mode , when there is a hardware fault in side it. Its a warning that some thing is wrong.
Normally
AV receivers show this when any of the output amplifier get some
problem. there are six amplifiers in this AV receiver. May occur when
the output diver transistors of any of the amplifier become
shorted. if the output transistor get shorted this will lead to flow of
current through the speakers. To prevent this there is a protection
circuit for each channels. One combined output of this protection circuit is connected to the system control. when the any of the output amplifier fails, the protection circuit detects it and switch of the speaker and sent data to the system control. when the system control get this data it will give a warning to the customer through display that PROTECT.
You have to check the amplifier.
for that you need digital multimeter,soledring iron screwdrivers etc
open the amplifier
, then power it on. connect the negative terminal of the multimeter any
where in the chase( metal body of the amplifer). then connect the
positive terminal to all the output transistors emitter pin one by one .
the voltage should be bellow 0.5V. If any of the emitter
of the transistor shows voltage more than 0.5V., then that amplifier
stage is faulty. Remove the transistors and check it. if it is shot then
replace with a new one.
after replacing the transistors do not power up the amplifier directly from the main. You have to put a bulb of 60 watts in serial.
You can do this easily remove the mains fuse. put the bulb
in a holder. now you have to wire from the holder. connect one of it to
the one end of the fuse holder and the other wire to the other end of
the fuse holder. Why using a bulb is, if there is any further problem in
the amplifier stage on which the transistors replaced, there is a possibility of the new transistor get damage. if we use a bulb in serial with its mains supply ,when any overload in the amplifier occur the bulb will drop the current, by lighting itself.
After connecting the bulb in serious power on the amplifier. watch the bulb. It should
light for one or two second and go dim . if so check the display, is
there is protect mode is on or not . if not and come back to normal
operation ,then remove the power , remove the bulb insert fuse and check
connect the power and check.
If the bulb shows bright light then there is some component also faulty in the same amplifier. after removing the power you have to check again the amplifier stage of which the transistor is replaced, for any other faulty components.

How to reset a pioneer vsx 456 receiver
To reset your Pioneer VSX-456 receiver, you can try the following steps:
Turn off the receiver.
Press and hold the "Enter" button and the "On/Standby" button simultaneously until "Reset" and "No" appears on your display.
Use the "Preset" arrow buttons to make the display say "Reset" and "Yes" .
Press the "Enter" button on the front panel to confirm .
If this does not work, you can also try unplugging all external devices before beginning the system reset. Switch the receiver into standby mode by holding down "Band" and then pressing and holding the "Standby/On" button for about two seconds. When you see "Reset?" on the display, press the "Preset" arrow buttons to make it say "Yes." Finally, press the "Enter" button on the front panel to confirm .
Pioneer receiver sx218 push power on clicks but nothing in front or any other sounds any ideas
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:
- 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.
- 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.
- 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.
- 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.
- 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.
