Has your TV got a built in Freeview tuner? If so, you can try this quick test.
Try unplugging the aerial cable from the Youview box and plugging it directly into the TV (temporarily unplug any loop-through aerial cable between the Youview box and the TV). Then try scanning for channels on just the TV. If it picks them all up that will verify that the aerial and cable are ok.
