Since yesterday evening my Freeview has been playing up. Channels such as Dave, More 4 etc started getting a very scrambled picture so I retuned the tv and then alot of those channels went missing. I've tried the switch off, unplug the arial trick but still no luck. I can only get half the channels that I use to get now.. I can't get ITV2 yet I can geta ITV2+1 and other +1 channels but the original channels still missing which is odd. Any suggestions on what it could be or what I could do? Any help appreciated.. it's a Samsung TV with Freeview built in.
