Two possibilities come to mind...
Firstly, Alexa, or similar. Is it possible that voice control of the TV would help him reset the source more easily?
Secondly, and somewhat more of a challenge for you, what about something like a Broadlink RM Mini 3. It seems to me that you would be able to place this in his home and provided he has WiFi be able to control his TV from your phone, obviously watching from the Webcam to see if you achieved what you wanted.
