Replaced SKY digibox with new Thomsom SKY+ box. No system problems with original digibox (connections: Digibox to TV and HDD recorder, HDD recorder to TV all on SCART). With new SKY+ box ( same connections) when I switch the SKY+ box to standby the TV speakers produce a very loud continious noise (audio feedback?). Is this a generic issue with the new box and/or is there a way round it. Thanks for any help.
