Transmit failure! ACP Error!

Hi

I´m trying to point my hughesnet .74m 1W terminal and I have done, but after 1 or 2 days everything goes bad again.

Since two days i don´t have Connection.

When I choose any G28 (IA8) transporder to pointing in each one the Rx Signal is about 45 and 56 and Tx signal is from 70 to 95 in some cases, depends of the transporder.

Well, the test pass and when I commisionate the modem (HN7000S) and restart the modem gives me the following errors:

Locking transmitter to carrier, Transmiter timing error.

When I launch Antenna pointing I get 60 in reception signal but ACP error in Transmission. Sometimes works, for 2, 3 minutes with 70 in Tx signal but next minute everything goes bad again.

What can I do???? I´m desperated.

Can be a dish deformation problem, my dish looks a little bit deformed, just a little, when you look closer.
