My TV used to be connected to a Freeview box via SCART. Whenever the TV was powered on the signal through AV1 was detected and it would switch automatically to the Freeview input. I now have a Yamaha A/V amp and my Freeview box connects first into the amp with a SCART-->3x phono cable, then on to the TV with a 3x phono-->SCART cable. This new arrangement does not give any switching signal to the TV and consequently when powered on the TV reverts first to the convention tuned channels. These are now largely redundant and it is a constant pain to continually select AV1.
