Pioneer VSX is an AV receiver that enhances the speaker’s sound. Sometimes, Pioneer VSX 921 poses the no sound issue.
This happens due to various reasons such as faulty source devices, cables, or wrong settings. You need to spend some moments if you want to fix your receiver.
This problem can happen more than once. So, each time you cannot call a technician. To repair these devices you need some unique tricks, these tricks will tell you exactly how you can fix your device by yourself within minutes.
Therefore, this guide is going to tell you some very useful tricks. Whenever your Pioneer VSX poses no sound problem, you can apply these solutions.
1. Examine the Cables and Power
Make sure your Pioneer VSX 921 is receiving enough power supply. The power cable should be plugged firmly into the receiver and wall power supply.
Also, make sure that your speaker and source device is powered ON. Carefully, inspect the power cords and connection wires. If they are exposed or bruised, replace the cables.
Sometimes, a faulty cable is the only cause for the no sound issue. Change the power supply and plug your devices into a different power outlet.
2. Check the Settings
Check the settings on your Pioneer 921. Select the right number of speakers. For example, if you have connected both A and B speakers attached to the receiver, select both A and B.
Similarly, if you have attached only one speaker (say A), set the switch to speaker A.
Check the headphones jack status whether it is in the detected or ‘use’ state. Disconnect headphones from your Pioneer, speakers, and source device.
3. Check the Compatibility
You need to confirm that the speakers are compatible with your Pioneer receiver. For example, it cannot work with a subwoofer and will not deliver any power.
Make sure the speakers are connected to the right ports. In addition, check the speaker wires whether they are compatible or not.
For instance, to connect a subwoofer, an RCA cable is needed. Likewise, HDMI or Optical cable is required to connect speakers.
Connect the cables and plugs to a different port on your speakers and source device.
4. Investigate the Source Device
The problem may be in the source device. So, check it separately by disconnecting from the receiver. Play sound through built-in speakers of your source device; TV, laptop, Blue-ray, or PC.
Look carefully whether the source device is detecting your receiver or not.
If possible connect the source device to a different receiver. Moreover, check the settings on your TV, Blu-ray, or laptop.
5. Test the Speakers
The problem may be occurring due to faulty speakers. You need to check the performance of the speakers. First, disconnect all the speakers from your Pioneer.
Now, play sound through the speakers directly to check their functionality. If they work fine, test them with your receiver.
Connect one speaker at a time and wait if your Pioneer gives sound. Disconnect this speaker and connect the other one. In this way, you can find out which speaker is corrupted.
6. Reset Your Pioneer VSX 921
If all the devices are working well, reset your receiver. First, try a soft reset and then factory restore.
The soft reset does not delete any data but helps remove software bugs and power cycles your device.
- Power OFF your Pioneer 921 and disconnect from the power supply.
- Unplug all the devices such as speakers and source devices.
- Wait for a few moments and plug the power cable back again.
- Now, connect the speakers, turn ON your receiver and check the sound.
If the soft reset fails to work, try a hard reset. It will restore your receiver to its factory settings. Thus, all the wrong settings will be reset and software bugs will be removed.
Hopefully, this will fix the no sound issue.
- Unplug all the external devices from your Pioneer VSX 921.
- Disconnect the receiver from the power supply and then reconnect after a few minutes.
- Now, press and hold the ‘Front Enter’ key and ‘Advanced Surround’ key for 2 seconds.
- Choose the ‘Reset’ option from the screen display on your Pioneer.
7. Hardware Damages
If no trick can fix your Pioneer VZX 921, it has a hardware defect. You can diagnose this by noticing the click sound.
Power ON your receiver and listen carefully if it gives a relay click. If it gives no sound, you should consult a technician.
There may be other hardware defects such as blown fuses, faults in the motherboard, or damaged circuit board. So, you should consult a professional to diagnose the root cause.
