I have. But I don't see how there can be a picture without the receiver being on.
Probably a bad connection in the box, just a guess.
The outputs should turn OFF when the on/off button is changed.
Remember, on a DVR, it is never REALLY OFF, as it is responsible for keeping a buffer of whats on TV on the channel your on, incase you decide to turn the TV on and want to watch what was on while it was off, you have a 45 minute buffer always running.
The only thing that gets actually turned off is the front panel and suppose to be the output as well, you would think.
Sounds like an electronic chip gone bad somewhere.
