I've got a fairly new house (less than three years old) which shares a communal sat dish, but we each have our own house aerials. So Sky is fine, but last night I lost all freeview on all our TV's (1 main TV downstairs and 2xsmall TV's in the bedrooms). I've tried re-tuning everything in, but the TV's are not picking up any channels. I've been up in the loft and I've got this - I've tried powering it all off, leaving it for 10 mins then restart and things improved slightly in that I picked up about 8 freeview channels, but the signal was really low and the picture is pretty much unwatchable. Prior to this I was getting upwards of 50 channels, includiong the HD freeview channels....so something isn't right somewhere! Does anyone recognise the kit we have? any suggestions on what could be wrong?
