Hi Waxhead, thanks for the reply. I was unlucky enough to have two of these for repair recently and found that they don't work without the media box connected (unless someone knows how to get them on). The link you gave me has faults very similar to the symptoms I have so I will check these suggestions. I don't know wether it is the media box or the tv that is at fault. Thanks for the reply, I will post again with any outcome. Thanks, Norman
