Every time I turn on the box and monitor an icon that looks like a speaker with a red cross over it appears on the screen. There doesn't seem anything wrong with the sound and I can remove the icon by pressing the V+ button and then the TV button on the remote. But what does this mean?
No, this wasn't the mute icon which is down on the right hand corner of the screen. This was a similar icon but with a touch of red in the design and up in the left hand corner. I still have no idea what it meant but it has, in any case, finally gone! Thanks for your help -- CHRIS
