Discover Media Radio Button Not Responsive

[Bill R]

The button to select Radio on my Discover Media System has stopped working. Pressing it does nothing, whilst all other buttons are fine.
I can still access the radio via the Menu button which gives me touchscreen selection of the radio but wondered if anyone had any ideas for a physical fix of the button ?

Have you tried a system reset?

Have you tried a system reset?

Thanks for that, just tried it and made no difference I'm afraid. I'm pretty sure it's the button as all the others have a discernible feeling that the button has moved up and down when pressing it whereas the Radio button seems like it's stuck

are you confident enough to take apart and clean / inspect mechanism?
