My Plusnet supplied Humax DTRT2120 Youview + box is connected to a Sony Bravia TV via HDMI and via SCART to a RF modulator so I can view in a bedroom. Suddenly this no longer works (no signal is output on the SCART) when the TV is switched off and Youview box is tuned to an HD channel or I try to playback a programme recorded in HD. SD programmes continue to work ok. This may be a handshaking issue to do with HD and HDMI and rights. Is there any solution? Has there been a recent software change to the Youview box?
As the SCART signal is not in HD there would seem to be no reason to prevent it working.
