Ok i change chanels and sometimes the reciever starts "thinking" all of a suddens shuts down and re starts it self and the channel appears usually on the hd channels it a vip 612 loking to 119 110 and 61.5 and sometimes gets kind of locked
I seen this the other day. Signal was weak. Re-aligned dish and fixed it. However I have seen this before and was a bad receiver. So check signals first.
