I have the Swann avdanced series security system, it was working good, now theses a blue screen with black very fast rolling lines through it, I cant see the screen to fix or change any settings, I've tried to unlug the DVR from the wall and leave it for a period of time, no help, I tried to change the connections on the back of the TV, it did nothing. Is there anyway to set it back (reset button)like it was the first time it was connected?
