Hello. The backlight of the buttons and the display of the radio stopped working. The radio is working, the display is working. There is simply no backlight. Tell me if anyone had such a problem and was it possible to fix it ? Not to change to a new one, but to fix the old one.

They're not bulbs but soldered in LEDs, which would need electronics skills to replace. They normally last the life of the vehicle, but there's always going to be exceptions I guess. Hyundai Ioniq 5 Ultimate. The family car.

The LEDs are whole, everything is shining. The reason is not in them. So I 'm looking for someone who had it and managed to fix it .

Have you looked to see if there is a PCB mounted fuse? That’s possibly a simple fix, if it has one & it’s blown. (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.

There is no fuse on the board. And when power is applied to the contacts, all the buttons are lit, and the display lights up. It is unclear where the problem is.

It sounds like a circuit diode has failed. Unless you have the skill & ability to trace it, you are out of luck. (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.

I think the brightness of the button LEDs is controlled by the dashboard dimming and also whether headlights are on or not. Are other parts of the dashboard lit up?

Yes, the backlight works on all other devices and buttons. Brightness adjustment also works. Only the backlight on the tape recorder does not work. Many people have such a problem, but they have not found a solution yet. Here I'm trying to find out from you, maybe the problem was solved somehow.

There will be a transistor/FET which controls these LEDs, probably on the same PCB. As you have proved the LEDs work, this is most likely the problem. If you can trace back the LED tracks on the PCB you might be able to identify which transistor it is.

I have the same problem, waiting for an answer

Hello. I gave the radio to repair. Previously, they said the imaging chip was out of order. These chips are not on sale. We're trying to replace it with something.

Hello. I ended up buying another tape recorder. The electrician said you need to change the PWM on the board, and the backlight should work. Try changing the PWM.
