Remote STB button powers TV

This is more of a minor annoyance than a problem, but wondering if someone has an answer.

I have a LG TV and a P265 remote.  Everything works fine (using code the LG code 210), except the STB button not only power cycles the box, but the TV as well.  Is there anyway to have it ONLY power the box and leave the TV alone?  I would actually prefer it this way.

By the way, on two other Samsung TVs, it does work this way.  The STB box powers the box, and the TV does not turn on/off.  I have to press the TV button separately to power the TV, which is how I prefer it.

Thanks
