none of my channels are working ive known for months my dish is out of alignment. but normally about half of my channels work. 2 days a go we had a power outage and ever since then no channels. i can get into system setup in my box menus. i get blank screen, with signal loss message flashing for a second real quick, then back to blank screen. box is a D12 box doesnt seem to be able to download the data from satellite but heres the thing, i rebooted my box 3 weeks ago. for 2 days i had no channels then i got half my channels back. i didnt do anything, just out of the blue the channels came back. im just trying to get half my channels back at this point. is there anything i can do or try?
