Verify that the batteries in the remote have been changed, there is nothing in front of the “eye” on the receiver blocking the signal from the remote, and the light is flashing on the remote when buttons are pushed. If the remote control does not light up and the batteries are new, contact DirecTV at 800-531-5000 to get a replacement remote control. If the remote control does light up but the receiver does not respond, contact our support line at 877-995-4675 to troubleshoot further or schedule a tech visit if needed.
