I’ve tried this on two separate Sony sets. My first problem is, there is a ton of red data that shows up in the middle of the screen that does not seem to go away, making it impossible to take a reading of the window pattern. Second, sometimes the proper adjustment will come up (GDRV, RCUT, etc.) but when I change off of it with 1 or 3, to scroll to the next thing, it goes away and doesn’t come back. I could send you some screen shots if it would help.
