Problem seems to be catching!! I "solved" the problem but do not really understand how - did it under the influence of red wine.
As I recall there seem to be two phases. Firstly I pressed "sound" "0" "store" (I think) on the 3000. This brought all the buttons back into use but did not help with the remote. I then used the "option " advice suggested in this thread to get the remote working..
I am sure Peter or one of the more techy guys can give you chapter and verse.
