I found this I don't know it this could help you remember the is a little older post reply but something in here might help you,,
C/P
when you use Antenna setup try a different tp
and freq. but first delete all 129 sat channels.
the different TP and freq should save when changed.
the do a rescan.
that works on my 9000hd. I use to get 475 channels
on 129...now lucky to see 250. there is a software
problem in v/s hd's that causes the TP not to see
all the freq's each.
as a test I did a scan at first...saved and went tp
change the TP and a new freq. when I went to channel
scan later I found over 550 channels some had 50 on
them not picked up by the first scan. so I know some
are there. problem was I ended up with dup and triplicate
channels...a pain as only some work...unless you go back
and reset the TP again. so just try one setting for a TP and
freq......then save it until software is repaired. save the search
with the channels you need.
I believe there is a problem with the auto TP functions.
good luck
