Are you wondering, “why does my radio turn on but no sound” come out? It is a common problem with radios, and there are a few possible explanations. In this article, we’ll explore some of the reasons why your radio might not be producing sound, and we’ll provide some tips on how to fix the issue.
How Does A Radio Work
Radio waves are the longest electromagnetic spectrum waves that carry information from a radio station to a receiver.
The term “radio” includes both the transmitter and the receiver and is derived from the Latin word “radius,” meaning “ray” or “beam.” In 1892, Italian inventor Guglielmo Marconi developed the first practical radiotelegraph system. Radio signals are electromagnetic waves of frequencies ranging from about 30 kilohertz (kHz) to 300 gigahertz (GHz).
There are two ways radio stations modulate their carrier waves: amplitude modulation, or AM, and frequency modulation, FM. AM radio broadcasts a carrier wave that maintains a constant frequency, while the overlaying sound wave modulates its amplitude. And FM radio maintains a constant amplitude while the frequency varies based on the overlaid signal. AM and FM radio carry sound waves-a type of analogue signal to your receiver.
The car battery powers the car radio. The battery supplies power to the car radio, and the car radio powers the car speakers. The car radio receives its signal from the radio antenna. The antenna captures the radio signal and sends it to the car radio. The car radio then plays the signal through the car speakers.
Why does my radio turn on but no sound?
You may need to get the traffic update but your radio isn’t helping. It can be a burning question in your mind if your radio suddenly stops speaking.
Unmute the Radio
Before going for mass investigation, make sure that the button of ‘Mute’ on your radio wasn’t pressed. It sounds silly, but people forget to unmute their radio while driving and talking to the phone in many cases. Then they start thinking ‘why does my radio turn on but no sound’.
When you are driving and have to pick up the call on your phone, your immediate instinct pushes you to mute the sound of the radio to get a non-interfering conversation and not to miss a word from the other part of the phone.
That’s why you need to be aware of this silly but important thing. If ‘Unmuting’ doesn’t work, you need to go to the next step to find the exact problem.
Check Wire Management
There are all kinds of wires in and out of the radio. Each cable serves a specific purpose for the car stereo to function properly. If you have a silent car radio, the first thing to do is make sure all the cables are connected.
Car radios always have three different power cables that connect to the deck area, Black (usually ground) Red, (usually a battery) and yellow (usually constant power). Make sure your car stereo connects these three wires correctly.
It should turn on the radio and work properly.
Check the speaker wires after verifying that the car stereo is properly powered.
Most aftermarket wire harnesses are labelled with a small text on the side of the wire so you can see what they fit. Most of the items in stock are only colour coded, but some are labelled. Make sure each wire is set up correctly and connected properly.
The colour of the wire depends on the year and model. Be sure to check the operation of each wire before working. However, the main wiring of concern is the speaker wire. These are the plus and minus wires that connect to each speaker. It will power on the car stereo and turn on the sound/power of each door speaker. After disassembling the dashboard, check each wire before proceeding to the next step.
Finally, if you are using an aftermarket amplifier for your door speakers, make sure they are turned on. In this case, don’t forget to check each device to make sure the connection is good.
If you are done with checking the wires and find no fault, there might be a problem with some other things. Let’s talk about them.
- A Blown Fuse
Like some other electrical appliances, car radios are guaranteed to have a fuse. They protect appliances from power surges and other electrical elements.
There are incidents where the surplus current is released to the audio component of the vehicle, which might cause the fuse to blow, and disconnects the circuit to save the radio itself.
Replacing a foul fuse will likely get your radio blasting again, however, note that anything that causes the new fuse to blow shortly after installation would require you to go to a car workshop because it means there’s something faulty with the electrical system as a full which an expert might properly check out.
- Faulty speaker or faulty speaker wiring
If the wires connected with the speaker are connected wrongly, the speakers won’t work.
There is a possibility that your speaker is ageing. Speakers are designed to produce sound waves, and the older they get, the less effective they become. A simple way to track this is by hearing sizzling sounds from your speaker. You can detect this sizzling sound easily by hearing. If you detect this, it is high time to replace your speakers. After replacing the old speakers, carefully connect all the wires with new speakers. Test your new speakers in a lower volume, and you can notice the difference.
- Faulty Antenna or Tuner
A faulty antenna or tuner is something that most people completely forget about when they face a sound issue with their radios.
In place of the old metal antennae, most vehicles now have wires running beneath the windshields, and while a damaged wire antenna will require a specialist, you can always replace an old-fashioned antenna yourself.
Pull down the mast via the fender to remove the entire antenna system, but be careful while handling the connectors.
Keep an eye out for gears, a motor, and a rope. If you notice the rope’s teeth are broken, you’ll need to replace the complete assembly.
Reinstall the assembly after you’ve cleaned it up. If you obtain a new assembly, follow the same steps. Make sure the mast is completely down, then link the nylon rope to the tube.
Connect the electrical wirings before placing the mechanism in place — this should cause the mast to retract — if it doesn’t, you probably didn’t do a good job, and you’ll have to repeat it.
- Software Issue
To get the stereo software to operate again, you may need to re-initialize it.
Like a phone or a computer, a car stereo can break down and malfunction. Your stereo should resume as if it were turned on for the first time after flashing the memory, which should resolve the problem. It’s possible that someone with access to the automobile messed up the audio balancing; therefore, you should double-check the settings before flashing the memory to save your data.
Frequently Asked Why Does My Radio Turn On But No Sound Questions:
Q. How can I tell if my radio’s speaker is blown?
A. If your radio is not producing sound, the first thing you should do is check the speaker. To do this, unplug the radio from the power outlet and remove the back panel.
