Tv pro remote Source button not working

[Takeaguess]

Recently went from the BT Tv to BT Tv pro. 

The previous remote controlled my tv just fine, the new one doesn’t let me change the source to switch to a different HDMI. I can turn off the tv and change the volume. 
I have reset the remote, and in Bluetooth settings volume and source is set to TV.

It seems there is no way to manually code the tv? Having another remote for just one button is excessive, annoying to the point I regret the “upgrade”.

TV is old but a Toshiba so a popular make.

Any suggestions?

if you retained your previous remote then that will also work with the BT TV box pro  if in line of site.

I was asked to send all equipment back so no longer have the previous remote which worked
