Hi I'm hoping someone can help because I'm useless when it comes to electronics. I have set up the LG BH9540TW using HDMI ARC to my Smart TV with both my SKY HD box and PS4 connected to the Receiver. If I want to watch Sky through the TV speakers (which I think most of the time will happen), I will obviously need to switch the receiver/Blu Ray player on too. Will this consume a lot of power and cost me a fortune. I think the player says 52 watts on the back. It would save the hassle of constantly switching the HDMI lead from the receiver to the TV for the Sky box but I don't really understand wattage and power consumption. If anyone could advise, I'll be very grateful. The surround system itself is fantastic.
