What is the difference between

and
- I turned on the TV on the sofa
?
What is the difference between
and
?
In terms of meaning, there isn't much.
This is because they both mean you were sitting on the sofa and used the remote control to send a signal from the sofa to the tv to turn on.
In general "on" and "from" have quite different meanings.
