i have cut channels out of the wall behind my plasma that i am waiting for (new pio) .so there is only going to be 2 cables actually going to the plasma 1 power and 1 signal cable. the media box is going to be in the room directly above the plasma, so i have channelled the wall streight down the middle of where the plasma is going to go. my friend then said will the power cable interfear with the pic with it going streight down the middle of the plasma. and will it interfear with the signal cable. to which i had no answer. so i thought i would ask you guys.
