Mercedes Radio Display Not Working

Mercedes Radio Display Troubleshooting

There are several reasons why your Mercedes radio display may not work as expected. We’ll cover one by one so that you can find the problem in your car and fix it.

Software Bug Can be a Reason:

One possibility is that there’s a software bug causing the problem. Mercedes radio has been known to have occasional software issues with their vehicles, so this is definitely something you should consider.

If you find that the radio controls are working fine but the display is blank, black screen appearing, or it’s stuck in the Mercedes logo, then the possibility of a software bug is high. In this case, you can perform a soft reset to solve the issue.

How to Reset Mercedes Radio?

Resetting a Mercedes Comand is pretty easy. Press the CD eject button for 10 seconds and wait for the Mercedes boot logo to come up. You’re done with the system reset.

Display Fuse Can Cause the Issue

Mercedes radios come with a fuse for display on the back of the unit. If this fuse blows, it will cut the display power and the radio will not work.

If you’re having problems with your Mercedes radio display, one of the first things you should check is the fuse. This is a pretty simple fix, and all you need to do is replace the blown fuse.

Here’s what you need to do for changing the display fuse in Mercedes-

  • Remove the radio unit from the dash.
  • Disconnect all the wires from the back of it.
  • Find the fuse on the back of the radio unit.
  • Remove the blown fuse and replace it with a new one with the same rating.

Loose Cable Connection

Another possible cause of your Mercedes radio display not working is a loose cable connection. When this happens, the screen will not show anything at all or it might frequently turn on and off automatically.

If you’re having problems like these, then check that all cables are connected properly. If you find any loose cable, reconnect it to the car stereo and try using the display again.

While checking the connections, make sure to use a multimeter to check whether the cables are producing enough current to the stereo unit. You may find that the connectors are well in place but there is broken wire somewhere in between that’s causing the unit not to have enough current to operate normally.

Bad Display

A Faulty or broken display can also be the reason why your Mercedes radio display is not working.

If you find that all other things are fine, but still there’s no response on the screen or low light in it then a bad display could be an issue.

There are two ways to check whether your Mercedes radio has a faulty or broken display – one by checking for loose connections and another by removing it from the car and connecting it to an external power supply and input system.

You should try both methods before spending money on replacing this part of the unit. The second one may feel overwhelming for some. In that case, you can take assistance from Mercedes service centers.

When it comes to the replacement LCD panel, it’s cheap. But the installation may take an hour or two for a DIYer. We recommend doing that from Mercedes service centers for an easy and foolproof fix.

Final Words

It’s important to note that Mercedes radios come with a fuse for display on the back of the unit. If this fuse blows, it will take out the display and the radio will not work.

There are other problems that may cause the display to not work as well. The good news is that you’re in luck!
