Hi,
We recently upgraded our TV to include a lot more HD channels but a number of them (most) aren't working at all or break up so much to be un-watchable. Have rebooted, plugged and unplugged wires but nothing happens.
Channels that break up: Sky 1 HD, BBC2 HD, ITV Be HD, NG Wild HD, H2 HD, Film 4 HD
Channels that just say 'there's a problem, give us a call': Sky Liv HD, E4, Channel 5 HD, SyFy HD, Comedy Central HD, Fox HD, Alibi HD, MTV Live HD, TCM
Any ideas what the problem is and how to resolve it would be greatly appreciated!
