Repairing a radio is possible when you rely on the advice of the pros. In this article, we will cover in detail on how to fix a car stereo that won’t turn on. So keep reading till the end.
HOW DOES THE POWER SUPPLY OF A RADIO WORK?
Several factors can be considered when the car radio does not turn on. This type of device has a standardized connection.
This allows it to connect to speakers and power. For some models, for example, a GPS car radio antenna adapter can ensure the connection in the event of a problem.
Thus, when a car radio does not turn on, the question naturally arises about the possible origins of this failure.
THE BASIC PRINCIPLES OF A RADIO STATION
The vehicle radio is an electronic component. Like all electrical components, they are subject to the same physical laws.
These electronic components are called “consumers,” especially if they are accompanied by various accessories, such as a dashcam, a rearview camera, or a car screen.
They can be lamps, seat heaters, auxiliary engines such as electric windows, or just a sound system in a car.
Electricity always flows in circles according to the most fundamental law of electrical engineering.
Without exception, every electrical consumer must be installed in a closed system. It depends on the energy source with positive and negative poles and the associated power lines.
All the cables leading to the consumer, the output line, and all the connections leading to the power source make up the return line.
So when a car stereo does not turn on, the problem is often with the power source and the wiring.
If you could fit every electrical consumer in a car with a complete private circuit, you would quickly have a massive bunch of cables.
For this reason, many manufacturers use the car body as a return line.
Both the battery and the alternator are connected to the body by a thick cable. This means that each consumer can connect to the plate to produce a complete return line.
Although it sounds fantastic and straightforward, it can lead to problems while installing car stereos.
WHAT TO DO WHEN A CAR RADIO DOES NOT TURN ON?
Now that you understand how the power system allows a radio to work works, it will be easier for you to repair the device if it breaks down.
For most current models, hands-free devices and connections for MP3 players are the gold standards.
Usually, radios are offered on the market with adapters, ensuring connection to the vehicle’s electrical system.
When a car stereo does not turn on, the yellow cable and the red cable are interrupted by a connector.
THE RADIO DOES NOT WORK
All are still in place, but the car radio doesn’t turn on? Depending on the problem, you will be able to find a solution.
A blown a fuse following a power failure in the car is often why the stereo does not turn on the vehicle.
So, you need to check the fuse box to fix the problem. It should not be forgotten that the car radio itself has a flat fuse right next to the socket.
If the fuses are intact, but the car radio is not yet switched on, the problem may be with the power supply. This may have several causes.
How To Fix A Car Stereo That Won’t Turn On?
To test the system, you can reinstall the original car stereo. If the unit is working, the essential function of the wiring harness is OK.
You can conclude that this is a connection error. There may also be incompatibilities in the car radio antenna adapter’s pins, which could cause the car radio to malfunction.
By using a multimeter, you can find out how the connections are occupied. Focus on the red, yellow, and brown or black colors on the car power cord plug.
Multimeter probes have a cap that allows the shaft to be extended and only one end.
Remove these connectors, and the probes can be conveniently placed into the different contacts on the connector.
The multimeter is to be set to 20 volts DC. This is critical for testing the form for the current assignment.
Following these various moves, you need to extract the ignition key before connecting the black sensor to a brown or black cable and keeping the red sensor in yellow contact.
THE PROBLEM WITH THE YELLOW OR RED CONTACT
In this scenario, you need to connect the black sensor to the brown or black cable and keep the red sensor in touch with the red one.
If the red touch issue occurs, the ignition must be turned on without starting the engine. You will use the same technique to evaluate the plus ignition.
THE APPEARANCE OF AN ERROR MESSAGE
Most of the time, when a car radio does not turn on, an error message appears on the screen of your car stereo. You may be dealing with this kind of typical message: “Bad wiring, check to wire then power on.”
In this kind of case, the car radio does not turn on and cannot even turn off. The problem may be related to the radio’s contact with the matter.
Even if you’re not a car audio expert, with the right tools and some patience, you can probably fix your car stereo yourself. We hope this guide was helpful and that you are now enjoying your favorite tunes on the road once again.
