Just for the last 2 or 3 nights I've experienced really bad break-up of my TV pictures.
We've already switched to digital (I'm in the Yorkshire TV area)...............anyone else having problems?
Perhaps its just us Yorkshire folk having problems, Craft. Ours has been very snowy for a couple of days, on the one downstairs, yet the one upstairs is fine. I thought it was all going to be better when we switched over. Another big CON
I couldnt watch ours downstairs as it was hurting my eyes straining to watch. I had to go upstairs and in the end I ended up switching it off anyway as there wasnt anything worth watching IMO
OK here in Barnsley....maybe your aerial has come loose either at the TV end or the roof end....look see if it has fallen off the chimney or come unplugged....
Disconnect your Booster if you have one and connect Digi Box directly into TV.
You will need to do a full Re-Scan as if it was a first day installation.
Your Aerial is spot on according to you, so it seems that the strength of your Signal is too strong by using Booster and it needs disconnecting now that you are fully Digital.
Transmitter Signal strength since the changeover will be very much increased !
