I have a 510 DVR and for some reason, even when it is powered off, both sets of RCA outs still send a signal. It's not enough to show a picture or sound, but it's enough to fool my automatic A/V switcher into not turning off, and it's enough to fool my televsion into not displaying it's usual blue screen when there is so no signal present. I have tested this on multiple televisions and still the same problem. Dish Network techs (both simple and advanced) swear that there's no way it could be sending a signal and that my equipment must not be compatible (and when I asked them if they are trying a new and groundbreaking type of RCA out signal that every piece of equipment in America is incompatible with, they realized what a stupid answer that was ). HAS anyone else had this problem or is it just me? It displays a dark picture.
