301-10 black screen?

[dw8]

I've got a 301-10 that went down. not part of the ecm but later. it was up and running then I ran into the check switch nag that wouldn't clear. i reprog the card
it would come up but as soon as you would change the channel it would goto the banner and black screen. It's not a box key issue iv'e read them and all is correct.
any thoughts from the dish gods? :cool:

If it was mine, I would reflash everything back to an early virgin version and start over, that would eliminate the bad software issue.
