I've been a tech for Dish Network for 12 years & Directv for 3 years. I also was a Paratrooper (509th)...
Nilsa error code 775 means ur receiver is not communcating with the satellite outside. If this is the receiver u've moved, make sure u have the wire connected properly to the outside switch or to the satellite. As a tech we only hook the wires that we use to the satellite. Normally the other wires in ur home we don't hook up. K2 comments

More than likely the issue arose when you move the other receiver. You need to ensure the power inserter is still located in its original position.

775 – Problem Communicating with Dish
Indicates your receiver is having trouble communicating with your satellite dish. As a result, your TV signal may be interrupted.
To solve the issue, you can try a few things:
Make sure all the cables connected to your receiver are secure.
You may have a device in your setup that looks like the device pictured here.
This is called a SWiM Power Inserter. Make sure it's plugged into an electrical outlet or an active power strip and the cables connected to it are secure. Do not plug in the SWiM Power Inserter to an power outlet that can be turned off or this could continue to impact your viewing experience.
If all of these connections are secure, try resetting your receiver. On some receivers, there is a small red button inside the access card door on the front panel. Simply press this button and wait for the receiver to reset. If you have a receiver that does not have this button, you can reset the receiver by unplugging the power cord for 15 seconds and then replugging it.
If none of these solves the issue, you may need to schedule a service call. You can reach DIRECTV customer support at 1-800-531-5000.
