How to fix a blown channel on a receiver

When working with any speaker or a home theater, there must be a receiver containing some more channels to create a good sense of music through its sounds.  A receiver works with specific sizes of a system to produce more excellent sounds when using it.  So if the receiver is blown, it means there are fewer channels that you can connect to the speaker, reducing the sound it will produce.

A blown channel on a receiver results from many issues from the speaker or the power supply agents you need to identify earlier. It is good to check the other devices connecting to it to reduce problems when using the speaker. To fix a blown channel on a receiver, check the controls if they have corrosions and clean the cables, which can cause other problems? Some of the causes of a channel on a receiver blowing are cable issues, fuse, overheating, and the controls.

Sometimes you can be worrying about what you can do with the blown channel. Budo, don’t worry. I will discuss the steps you can follow when fixing the blown channel on the receiver and the possible causes of the blown track. Later are the frequently asked questions, then finally the conclusion which summarizes the whole article.

How to fix a blown channel on a receiver

Before starting the process of fixing a blown channel on a receiver, you need to identify if the receiver channels get blown so that you can choose to select them or not. People always ask if the receiver channels get blown, of which it is. Yes, the receiver channel can be blown at any place so long as you switch the volume too loud. In some cases, the tracks can be blown simultaneously when using the speaker, and you can lose all the media at once.

The chances of blowing the receivers on channels depend on the type of receiver you are using such that if it supports more channels, all the tracks get blown when they get blown. When using certain receivers, consider having the circuits that shut them if they produce large sounds since they operate as digital fuses.

Always remember to read the manufacturer’s instructions before trying any troubleshooting process to avoid missing some concepts. You can also consult a technician if you try the troubleshooting process and find it hard for you or not working. Always remember to read the manufacturer’s instructions before trying any troubleshooting process to avoid missing some concepts. You can also consult a technician if you try the troubleshooting process and find it hard or not working. Below are the steps to follow when fixing the receiver channel.

i. Gather all the requirements you need for the fixing process

Before starting the troubleshooting process, consider collecting all the tools that can help you fix the receiver. Some agencies include the screwdrivers, iron and solder, electrical contact spray cleaner for cleaning the speaker terminals and other dirty parts within the receiver, compressed air, and a millimeter. Ensure you cover yourself with an antistatic wrap that prevents you from having any electrical injuries.

ii. Switch off the receiver

To switch off the receiver, consider removing all the electrical cables from the power supply.

iii. Inspect the cable connections in the receiver

After switching off the receiver, check the cable connection and confirm if they are correctly connected to the receiver and other parts within the system. If using wired speakers, ensure the cables are plugged in perfectly into the speaker’s connection ports. However, if you connect everything with the wires but the channel is still blown, move to the next step to fix some other problem with the receiver.  

iv. Check the state of the fuse

When it comes to matters of the fuse, there are different steps you can follow to make the fuse better. First, check if the fuse is blown. Sometimes the fuse gets blown, but the rest of the channels are still good. If the receiver’s volume is too high, the fuses can shoot out, or the knobs on the fuse knob at the back of the receiver switch off. You have to unplug the receiver and check the system if any electrical issues cause the fuse to blow. If there are no electrical issues, check if the fuse has any damages. In other words, check the whole fuse section to remove the faults or fix them.

The second step here is removing the fuse to check if there are electrical issues and do the correct thing. If the fuses have damages, you can remove them from the system and review the rest of the problems. Ensure you carefully remove the fuse to avoid causing injuries to the whole system. 

The third step is fixing a new fuse after removing the older one. To get the new fuse you can visit any electronic shop that sells the products. There is also the Amazon site that offers quality products at an affordable price.  Ensure you get the specific size of the fuse that matches the receiver for them to work correctly together. After replacing the fuse, you can test the receiver to confirm if it’s working. If there is some more issue with the receiver, you can move on to the next step.

v. Clean the CD tray in the receiver

Not all receivers have the CD tray in them, but CD trays must work with them for the old receivers. Therefore, all you need to fix to the receiver is to spray compressed air into the CD tray, which is a form of cleaning since it removes dirt on the CD player. Dust particles can limit the capacity of a receiver to read an inserted CD.   

vi. Check if the system is overheating

When checking for the overheating parts, consider checking the intake vents on the sides of the receiver. Sometimes, if the ducts have dirty particles, the receiver overheats and later shuts down. Overheating results from damages to the hardware in the receiver that you need to fix the issues with to reduce the overheating.

vii. Inspect the state of transistors

Transistors in the receiver are in the internal parts of the system. The transistors blow so quickly in the receiver that you need to check them frequently to avoid some issues with them. There are some ways that you can use to limit if the transistors are good or bad. After this, you need to test the receiver and ensure everything is working correctly. But if the process fails to work, move to the next step.

viii. Consult a technician

If you tried the whole process with your receiver, but the channels are still blown, consider consulting a technician to help you fix the problem. The technician can fix the problem quickly without wasting time and effort, unlike you, who focus on minor things that cannot help your receiver.

Causes of a blown channel on a receiver

Causes of a blown channel on a receiver

Faulty resistors

If the resistors in the receiver have some faults, it will cause some other problems with the receiver, such that it can cause the channels to be blown and some other issues.


Overheating of the receiver shows that there is a supply of excess heat in the system. The extra heat then causes overheating that can later lead to damages to the channel on the receiver.

Dirty particles in the CD tray

The CD tray holds the CD when using it to play music. Sometimes the CD contains dirty particles that will accumulate in the tray, causing some issues. When the tray has dust particles and other debris, it will blow the channel on the receiver.

Faulty fuse

A fuse controls the amount of power that is transmitted to the receiver. Therefore, when the fuse is blown, the receiver will receive excess energy that can cause the channels to blow and create other problems.

Frequently asked questions;

What shows that the connection of the channel to the receiver is correct?

After trying the troubleshooting process, it is good to test other activities to show if the channel’s connection is correct. Therefore, you need to perform some actions on the receiver to help you fix everything in the machine. Below are some of the activities you can try with the channels:

a) Connect and switch video sources

b) Connect and switch audio sources

c) Decode surround sound formats

d) Amplify audio signals

e) Drive multiple speakers


When using the receiver, you can suspect if the channels are blown or still good. If the tracks are blown, you can choose to troubleshoot the whole system to work correctly. The article above shows the steps you can follow when troubleshooting the receiver with blown channels that you need to focus on the main areas like the resistors, the trays, and other parts. In most cases, the causes of the blown channel result from the details of the system.

Kindly follow the guide carefully when you have the blown channels on the receiver. Always remember to read the manufacturer’s instructions before trying any troubleshooting process to avoid missing some concepts. You can also consult a technician if you try the troubleshooting process and find it hard for you or not working.
