Radio display blank

Hi

I've got a 2015 rapid. A couple of weeks ago I noticed the screen that shows the radio, phone and settings was really dull and hardly visible. Now the clocks have gone back I went to go and change the clock time as it’s not automatic. The screen is now completely blank. The touchscreen still works, the radio will still change channel (I know the rough location of the buttons so even though I can’t see them if I press in the right place it works). Anyone have an idea what could be wrong? I thought it may be a backlight to the screen or something but I’m not great with this stuff! Any help appreciated 😊
