Hi - hope you can help - thank you. The radio on my Sony CDX-M850MP does not work. The display does not show anything. I do not think the flexi-cable is faulty as the display work fine for everything else. CDs work fine. Do you you have any ideas what the problem is? Have I locked up the radio somehow? The only time you can see it's on radio is when you press the volume control - you see the volume and the radio band above it. The radio does not respond to buttons. Thanks again.
