Just started to get the occasional random 'Tune fail' message. On startup the default channel is displayed correctly, however when changing channel I may see the 'Tune fail' error. After 5 to 10 minutes the problem goes away and the picture clears. This occurs on FTA as well as encrypted channels on both fixed and moveable dishes on either inputs. So don't think its LNB related.
Current software is Openvix 4 1 004. This problem did occur before installing the latest Openvix so don't think its image related.

The satellite receiver is VU+Duo.

Anyone else had this problem and knows how to fix please?

Thanks
