Can’t find signal with new replacement dish

I forgot to add, I have a HR24-500-R receiver 

Hi, Danusuallycan. We're sorry to hear you are experiencing no signal your dish was replaced. Do you see any error messages? If yes, what's the error message? Jade, DIRECTV Community Specialist

The error message is the same one you get when signal is blocked by weather or an obstruction. 771

We're sorry for the inconvenience. If you encounter error code 771, it indicates a communication issue between your DIRECTV receiver and the satellite dish. For troubleshooting steps, please visit:

Let us know if it works. Ariane, DIRECTV Community Specialist

That was not helpful.  What I need at this point is to determine whether the connection between the dish and the receiver is good or not whether there is a signal or not. I know there is no signal.

We regret if the problem was not resolved. Let's get this fixed. In order to provide additional help, I've sent you a DM, so we can access your account for further investigation. - Ariane, DIRECTV Community Specialist

Do you have the 21v power inserter installed?

Yes I have a 21 v

Just to make sure the power inserter is connected to the red power pass through port on the SWM splitter?

Did you also replaced the mast?  If it is not level then the dish will be off.

I finally got it to work.  I changed the elevation 4 degrees at a time and slowly rotating the dish across about a 30 degree arc until I finally found a signal.

thanks for the input
