I own a Hitachi Ultravision 510WX208 which is about 5 yrs old.
Was watching ESPN this morning put the TV on pause (DVR's are great) and when I came back the TV had a black screen and no sound.
I checked all connections and TV still won't work. Checked the TV all day and still no go.
Any ideas?

Here is a dumb idea; it isn't the dvr that has failed, is it?
