Toyota Corolla Radio Display Not Working
Before you tinker around and try to fix the issue with your Toyota Corolla radio display not working, it is best to find out why this may be happening. There are many reasons behind this issue, and here are just some of them.
1. Dimmed Display
The most common reason why your radio display is not working is due to a dimmed display. It is important to check the brightness setting, which you may have turned all the way down. Hence, it is impossible to see the display at all.
For some, they may have gotten infuriated with the dark and unresponsive display only to find out that the brightness is all the way to zero!
So, if you are not seeing anything on the display, or you think that the unit is unresponsive, check the brightness and turn it up.
2. Connector Wire Issues
Next up, you may be encountering problems with the connector wires malfunctioning. This is another common issue with the radio display, which means the wire’s configuration may be messed up.
One common symptom of this problem is when you notice the screen stuttering a little while at times, it may go completely black. When the screen is blank, then it could be caused by some mismanaged wires. Thus, you may need to check the wiring and then determine the cause of the problem.
It could be that the display is soldered right onto your main unit or connected through a wire. When it uses wires, it may be that the connection is simply loose. This often happens because of tension.
With a poor attachment, this inhibits the display to receive ample power that it needs. Hence, the display tends to act up.
3. Fuse Issues
When you have a defective fuse, this can impact the performance of your radio display. In worst cases, the radio will not turn on at all because of a blown fuse. Although fuses can be a bit of an outdated feature, they prevent the chances of short circuits, which is why they are still effective, nonetheless.
With this in mind, you need to check your fuses and be sure there is no defect or damage to them. The fuse you need to inspect, in particular, is found right between the power line and the display unit. Perhaps you installed a new stereos system to replace the stock unit. There may have been a compatibility problem with the aftermarket radio because of a defect in your fuse.
So, if you have a blown fuse, all you need to do is to replace it with a new one, and it should be good to go.
4. LCD Panel Damage
Stock panels may be durable, yet there are always issues with getting a bad unit, unfortunately. So, if you are not seeing anything on your display, then there may be a defect from factory assembly, which needs to be changed.
Sometimes, the display may not show any problems at first. But over time, defects may occur when you have a damaged LCD.
In this case, it is best to get it replaced and your radio should work as it should.
5. Head Unit Problems
Another thing to take note of is that the car’s head unit may have problems. When this is the case, you may not see anything on your display at all. Each electrical component in your car comes with a purpose. And yes, it is prone to damage.
Some common contributors to these malfunctioning issues include dust build up, which leads to your circuits having problems.
