My mother-in-law has a 9300T and an old Panasonic DVD Recorder. The 9300 is connected via HDMI and the Panasonic via SCART.
She had a 7 year old Panasonic Viera TV that has failed and we have replaced it with a (cheap - £250) Samsung LED. With the Viera, and the two boxes connected as described above, the TV would automatically switch inputs when either the Humax or Panasonic was switched on. She is elderly so this worked great for her.
With the new Samsung, the TV input switches OK via SCART when the Panasonic is turned on (and with the Humax, if I connect it via SCART), but the Humax, via HDMI, does not change the TV to the correct input (I have tried HDMI 1 and 2) and the input has to be changed via the TV's remote.
The TV retailer tells me this is because the Humax does not send the correct signal to the TV via HDMI to switch inputs and that the Samsung TV is not at fault. But if this is true, why did the Humax switch inputs correctly when connected to an old Viera?
Are they correct that it is the Humax design that is the problem? If so, any suggestions?
My only thought is to connect both boxes to SCART via a SCART Splitter, but I haven't tried this yet.
Elderly ladies and new or changed technology don't mix!
