I am connecting my DVD player and freeview box through my surround sound stereo. I have got it all working but 1 thing. The TV Defaults to analogue tv when switched on now. This never happened when freeview was connected directly to the tv. the s/s amp also switches video aswell as audio. Q. what pins do i nead to connect/short in the scart plug to get the tv to think it is still connected with a scart lead ie. power on to the AV channel?
