Every time I go to MAXHD I get satellite signal lost "129" on my 622. All other HD channels are fine. I don't have another receiver to try. I've tried rebooting and check switch, but it still happens. Would anyone know what's wrong?
What's your signal strenght on 129 TP 27. While on channel 9458, go to Menu- 6-1-1. Most likely the SS is too low and it can't lock the signal. You will need to repeak the dish or have Dish Network do it for you.
