- Broken LCD Panel
- Defective Head Unit
Now, let’s have a look at these problems in detail as well as the solution of these issues.
Brightness That Is Not Adjusted
It’s possible that you complex your search for the root cause of the problem, but it might only be a minor issue.
So, you should start the diagnosis with a dimmer setting. As in most display units you have the option to adjust brightness.

So, make sure the brightness is set to the right level if this is the issue with the display of your car radio
Faulty connector wires
Another possible issue that can cause the unresponsiveness of your car radio display is the misconfiguration of wires.
In this problem, the display of your car radio might look a bit sluggish often. Also, In other instances, nothing will appear on the screen.
It’s also possible that the wires are completely damaged and hence you’ll see a blank display.
You might have to work a bit more to identify this issue, and the effort will be worth it as you don’t really see anything on your display.
There are two options for installing the radio display to the main unit, first one is soldering and the other one is wiring.
And when you are using wires, you must expect that they are always vulnerable to loosening. Even tension can damage wires.
When a wire is not connected properly, the display may not receive enough power. And eventually the car radio display will not work properly.
So, if you are also facing an issue of no display you must check and fix the wires of your car radio system.
When you find the faulty wire make sure to fix it using your Soldering Kit
Deficiencies In The Fuse Box
If your car’s display unit has a defective fuse, it may cause problems. In some cases, you won’t be able to operate the car radio while the engine is running because of a blown fuse.
Short circuits are often prevented by using fuses, which is an old, but efficient technique. And it might be possible that the fuse of your car was intended to protect your radio from an unexpected short circuit.

Hence, if your fuse is blown or faulty your car radio display will not work properly.
So, make sure to check whether the fuse is blown or not. And if the fuse is blown make sure to change it so that you don’t face any kind of display issue in your car radio.
Defective Back Light
If the fuse is functioning properly, but still your car radio is not working, you need to check the back Light of your panel.
A basic display is usually found on almost all old car stereos, and it’s emitted by a small LED lamp hidden behind the panel.
So, it’s an issue you are facing. Simply remove the front panel, disassemble the LED, and swap it out with a fresh one.
As I said in a few lines back, it mostly happens in old cars. Because new car stereos come up with LED display screens and you don’t need to bother for the back Light.
Broken LCD Panel
It’s true that stock panels are generally reliable, but exceptions are always there.
It’s possible that you won’t face any problems in the early days, but eventually a defective LCD panel will reveal the problems.
It’s also possible that your display got defective while assembling or some other time. And that’s why your car radio works but there’s no display.
So, if you face the issue of Broken LCD panel of your car radio you need to change it for the proper functioning of your display.
Defective Head Unit
In your car, the head unit is the heart of the infotainment system. And if it’s in poor condition, you probably won’t be able to see anything on display or won’t hear any sound even the car radio is on.
There is always a possibility of a malfunction with an electrical component, as well as the main unit of your vehicle.
