We have a panasonic SC BTT790 in the lounge with 2 wireless boxes to make it a 7.1 system.
In the bedroom we have a samsung UA40d6003smxrd 40 inch TV in the bedroom.

Here's the issue:
Turning on the home theatre in the lounge turns on the TV in the bedroom, and turning off the TV in the bedroom whether its by its own remote control or the power switch on the TV itself turns off the home theatre in the lounge.
Using the wireless remote app on my iPhone/iPad for tbehome theatre also turns on the TV in the bedroom...?

I am perplexed.
Anybody have any ideas as to why this maybe happening? Or experienced something similar?
Cheers
