Hi looking for a bit of help here
Been reading up about the hdmi cec feature and thought it would be good to use

I currently have a lg42lw450 tv which has cec (simplink) function
But for some reason the TV set won't accept the receiver it just has all options greyed out

I set the options in the vix menu for hdmi cec and also if I select the option to pass volume keys through that doesn't work either if I press volume after that option it just does nothing

Now I don't know much about hdmi cec and have never used simplink either so don't know if it is hdmi cable dependant or not
Just looking for a little but of advice/help
