You have the new xKu LNB, you won't be able to get signal on any F1 channels (ch 299, most SD channels) until your receiver has been updated by a CSR.
Tuning to an F2 channel (I use APTN ch. 350/70 but 700/701/750 should work fine, too) will allow you to get signal to the receiver so a CSR can update it for the new LNB.
You can also use one of those F2 channels and the signal strength screen to align your dish, however it has given me trouble more than once. I recommend using a regular Quad LNB to align the dish (use ch. 299), tighten it down, then throw on your new xKu LNB and tune your receiver to an F2 channel (APTN 350/70 ) and you should have a green light. Call customer service and they can now change your v-code to the correct one for the xKu LNB.
The 630 has a bad habit of rebooting in the signal strength screen. Use system status (Options, 4, 7, I believe) and wait a minute to check strength and Ecb/No.
If you are trying to use the DVR630 to align your dish, I recommend using a different receiver, preferably not of the 6XX series.
Also worth mentioning, if it's a brand new dish you are using, it may have the new xKu LNB. The one in the middle of the picture is the xKu and the far left is the regular Quad LNB.
