My hard drive recorder was set to record a radio2 programme but all I got was the radio2 logo but no sound. When I select the radio channel, and other radio channels, I get a brief 5 seconds or so of sound then nothing. I accessed the system menu to auto tune the channels and while the menu is on screen the radio sound comes back on. The radio goes off when I close the system menu. It's only just started doing this in the past week, the tv channels are all fine and record fine. Can anyone suggest anything I can do?
