Sometimes the car radio shuts down by itself, and we may get some ideas about why does this happens. But when the radio is working fine, when the radio station is playing on your car radio, but you cannot see anything on display, then this is a great challenge.

Our writers have come with a good set of knowledge that will help you to understand the reason behind your car radio display to stop working. There can be many types of reasons behind this problem, and the one cannot give the exact reason for the display to stop working.

Dimmer not adjusted

Every car has a different type of car radio, which comes with different features and different types of problems. We cannot say that all radios can have a similar problem, but the problems that we are discussing with you are similar in most cases.

Many car radios come with a feature of dimmer adjustment. This is so because the car radio display is very bright sometimes that it creates disturbance in the driver’s visibility. It is also used when the day is sunny, and the radio display is not visible to you so that you increase the brightness of your radio using a dimmer.

Dimmer is included in many car radios to provide the feature of controlling the brightness of your car radio display. Sometimes, the dimmer is not adjusted according to the requirements of the person using the car radio. And because of the issue, the driver cannot properly see the display of the car radio.

Solution:

The best solution for this problem is to locate the dimmer button on the car radio. The dimmer is usually set with the volume button by changing the selection from a dedicate button and then changing with the volume button.

You will not be able to see the setting properly, so you will have to realize on your own while selecting the dimmer option and configuring it with the volume.

Problem in connectors

The display of the radio is connected with the radio with specific wires. Some car radios have wires between the display panel and main unit of the radio while some are soldered on the board. Every radio has a different type of connection between the display and the main unit of car radio.

Two ways can connect the display of the car radio. Either the display is connected by the connecting wires with suitable connectors inside, or the display is soldered on the main unit. When the display is connected with the connectors, the connectors can get loose or damaged by any means.

Your car radio may have damaged connectors that are not able to transmit power and information to the display LED, and it is not able to work. There can be several possible reasons that can cause the connectors of the LED to stop giving power.

The main reason for the damaged connectors can be a loose connection of wires of the connectors. There can be a possibility of broken wire, and there can be a possibility of carbon stuck with the metals of the connectors, etc. Sometimes the manufacturers cheap out while installing connectors in the car radio. The possibilities, as mentioned earlier, occur because of that.

There is another reason for the display to have a poor connection is, it may have a soldered connection with the main unit, which is damaged. How can the soldering be damaged? Somepeople do not use their stereo carefully because they get angry when their stereo starts to mess up.

There are many examples for rough use of the stereo that sometimes the drivers end up hitting the car in very bad bumps on the road, that the jerk taken by the car also affects the inside interior of the car. In thisway, the car dash also takes a huge jerk, which effects the car radio too. That causes in breaking of soldered items like the soldered display of the radio.

Another good reason for breaking of the soldering is that people punch their dash whenever the radio started messing up, which damages the radio very badly. This is one of the reasons how the display connection breaks.

Solution:

The possible solution for the problems mentioned above is that the connectors of the radio should be replaced if the connectors are damaged. If the wires are damaged or cut from somewhere, then they should be repaired.

If the soldered connection of the display is broken, then you must open the radio and solder the connection properly. In this way, you may be able to get the display back in working.

Defective fuse can causes car radio display to stop working

The fuse can be a problem when the display starts to create a mess for you. Many car radios come with a dedicated fuse to save the radio from the short circuit. It blows itself whenever there is an irregular flow of electric current to the car radio.

How can a fuse be a problem when the display of the radio is not working? The fuse is the thing between the main power and the car radio. When the fuse blows, the power cuts off from the radio. But sometimes the fuse is defective in such a way that it is not transmitting full power to the radio. The defective fuse can be a problem in case of a dim display or no display on the car radio.

Solution:

The fuse of the car radio is usually located between the main power supply and the car radio. Locate the fuse and replace the fuse with the good quality build.

Main Head Unit is defective

The car radios are the type of electrical equipment in the car that does not need to be replaced so often. So, we can say that car radios are one of the oldest accessories that remain for a long time in any car because they are not easily damaged.

So, your radio may have been old, or it may have been with some issue which has not been noticed for a longer time. The car is always dusty, and because of that dust, different accessories of the car pull the dust in them. The car radio is one of those parts which is not cleaned for a long time because there is no good reason to pull it out of the dash.

The dust particles can affect the main unit of the car radio, which is the result of that can create any malfunction in the car radio. A defective display is one of them. The main unit, which is the circuit board of the car radio, can get defective from anywhere and cause the display to turn off.

So, if you cannot get the display working in any way or cannot find any good reason for the display to get defective, then there is a possibility that the main unit is damaged.

Solution:

The solution for the defective unit is that, if there is any small defect because of which the display is not getting enough power to work, then it could be repaired easily by a technician. If there is a big error in the main unit, then you should get your car radio replaced with a new one. Because the main unit is the basic thing inside the car radio.

Backlight or LCD is defective

Many car radio models have a basic digital display to get a better look at options and understand the operations better. So, they come with a simple display that is brightened by a backlight that is connected behind the LCD.

The backlight is responsible for the brightness of the display, and it is also responsible for the visibility of the display. So, if the backlight is damaged, then it means that the display is no more visible to anyone. You may have replaced the backlight once or twice before because the backlight often disturbs the display when it is being used for a longer time.

Another problem can be the defective LCD, which is a common cause for the display to stop working.

Solution:

The solution to this problem is that if the backlight is defective, then you only have to replace the backlight of the car radio. But when the LCD is defective or being replaced many times, then you must install a better quality or an original LCD by buying them from the manufacturers.
