Anyone figured out what frequency works with this yet as a few weeks ago had a different tp frequency which now is unscanable and doesnt clear although shows signal bars but the current tp for this is 11068 V 23000 and doesnt even get seen as has no signal on bars - thought at 1st this could be a HD unclearable issue with providor but theres no SD version and 11068 V 23000 the correct tp cant be seen - weird.
