We had an issue the other day (lightning) and had to have a new reciever because the HDMI port no longer worked. They sent a replacement Hopper and we FINALLY got it all set up and got all our recordings from the old one on an external hard drive. However, when I go to Diagnostics, it shows Red X's in all the boxes for Tuner 3 and in the Conn boxes for Tuners 1 and 2. Any ideas?
The lightning may have caused other issues with the dish then. Can you take a look at it and see if anything looks amiss or if something may be blocking it like branches? Also make sure all the cables from the Hopper to the wall are hand tight.
