In the past couple of days I have experienced a loss of picture (totally black screen) but retained perfect audio. Both times it happened as I was switching channels, or going to the EPG, I don't remember which. This happened once each to a 3900 and a 501. These two IRDs are on separate antennas/lnbf's.
In both cases power off and then on did not immediately fix the problem. After switching around from channel to channel, the EPG, etc. the picture finally returned.
I'd call Dish tech non-support but I don't feel like taking their "harrassment" to see what they know about this.
It just seems strange to me that the same symptom occured on two different receivers on two separate antennas.
Anyone else experienced this?
Thanks.....
