Hi folks. I've been having trouble with Itv, Chan. 4, Chan 5 and a few others recently, ie no picture. I can get these channels on the TV upstairs but not on the one downstairs. I keep on trying to re-tune the downstairs one but no use. I've lost these channels, and a few others completely now. It's the same aerial, which is old, btw. The upstairs TV is a bit newer than the downstairs one. I've tried plugging the aerial straight into the tv rather than going through the dvd recorder but its the same. I've got a booster in the loft. Any ideas?
