HD Channels Won't Work

[tw87]

Have an openbox here and no HD channels will work. It comes up with green glitching across the screen. Their SD counterparts work perfectly as does every other SD channel but I can't get HD to work.

Have another Openbox and works perfectly from the same feed.

Any ideas?

I had the same problem with a s10

The SNR drops right on the HD channels.

I put it down to a faulty tuner and got it exchanged.
