This is probably a really stupid problem :(, but any help would be great. Anyway we moved place, dont have sky anymore, and are unsure of how to hook up the tv. The model is a Panasonic, TH-42PA50A.

The wall jack, and the tv cable (plugged in, other end showing).

The back of the TV with leads from the dvd player/stereo box and the wii

The back of the dvd player/stereo box
Basically the only place that tv cable seems to fit is in the back of that dvd/stereo box, but that bit is labelled FM (and doesnt seem to work regardless). Do I need to buy another cable? Or is there some tuning trick or something that I am missing?
Any assistance greatly appreciated ^^
