I just realized it goes into a splitter, then one end goes to the box, the other into the modem, and I also have HDMI inputs and of course, audio/viideo. I just recalled that the box is new - swapped out the old box after purchasing the televison 4 a few months ago. I have had FIOS for years, and the change was going from the SD televison to the LED sytle, so I had to upgrade the box.
I watch HDMI 2 and when I turn the television on, I see a box chosen on the lower right hand side of the set. I exit out of that and I see the picture.
I am sorry I don't know the board etiquette. I honestly appreciate everyone's input. If I consider the problem to be resolved, I won't receive any more replies.
