Every morning my DVR is set to update. This process usually takes more than 30 minutes. This morning, my wife did not want to wait for the update to finish and pressed the reset button for 10 seconds so that she could watch the news. Since that time, our TV screens (one with the DVR and another in a different part of the house) have a message in a retangular box that says "no signal". I contacted Dish Network and after going through their process of checking everything, they said that the DVR needs to be replaced. Is this true? We have approximately 75 hours of recordings on our DVR and want to save them! My questions are: Do we have to replace our DVR? Can we salvage the recordings on our DVR?
