I have one of those Sony CRT 65" XBR's with the flickering CRT issues.
It did it for the customer oh-so-slightly, but drove him nutz.(doctor)
He gave it to me. It did it several months for me, then it settled down
and has been perfect a year now.
Sony did say it was "self correcting" if you wanted to burn it in a
thousand or so hours. Had to do with the coating on the internal CRT
elements. (cathodes?)
