I do not disconnect Reference I disconnect the HDSDI video input. I've found with Sony decks that even if you are set to internal video signal generator if there is a glitch on the video input the deck burps. It doesn't make sense but that's how they work. Because of this I always unpatch any video input to the deck before blacking.
Another thing I notice is the output of the deck changes drastically in timing between normal input/EtoE mode and when set to internal signal generator. Also when I switch to internal signal generator the stop light starts flashing like there is some sort of reference issue. Because of this I got in the habit of always setting the machine to servo reference the video input when blacking tapes.
I just got of the phone with Sony and I'm going to try a first birthday to see if that alters the behavior. I'm not sure this is a problem but the Sony tech confirmed you can black a tape with the machine connected to nothing. In that stand alone mode if I am monitoring the composite character output I wouldn't expect the character box to sway left and right in the picture which is what I'm seeing now. I'm sure I'd have noticed this before if it always behaved this way.
