Bought the new Smart Box a couple of weeks ago and immediately noticed this flickering white line at the bottom of all Freeview HD channels. Very distracting during darker scenes. The flicker may come from a failing connection ribbon or another electrical component that's near failing.

Flickering caused by internal connection problems appears consistently regardless of the video source. You need a trained professional to fix this type of flicker, though such internal issues often indicate that your TV may be near failing and needs to be replaced entirely.

LCD screens are always flickering during use, but the human eye doesn't see fast enough to notice the flickering if the screen updates fast enough. Adjusting the screen or room brightness can resolve this type of issue.
