Try unplugging that receiver for 1 minute then plug back in. That will reset the receiver & could help. U need to call directv at 1-800-531-5000 right away so we can come out & fix this. Even if the reset works still call.
Do a hard reset of your receiver. While the receiver/tv is turned on unplug receiver from electrical outlet for 15-20 seconds, then plug back in - this will cause your receiver to reboot. If this does not resolve the issue call 1-800-531-5000 and speak with Technical Support. Be prepared for some hands on troubleshooting.
