You could be picking up 110 on the 119 lnb as stated earlier in this thread. In order to verify this you should look on the Y plastic yoke that your lnb's go into. It should say 110 and 119 on them. Cover up the 119 lnb with tin foil and see if you still have signal coming in off of the 110 lnb. If you are still picking up 119 on the 110 side then that means that you need to move your dish to the left (facing the dish) and lower the dish a few marks on the elevation scale on the dish.
To prevent from picking up the wrong satellite on the wrong lnb again, cover up the 110 lnb so that you can pick up 119 on the 119 side and listen to the pitch indicating that you are receiving signal again.
