@msh You have no idea how much I raged. And the thing is, I KNEW about that issue and thought I had turned it off for that HDMI input. But I probably thoughtlessly changed it back when watching a movie (it was a PS2).
The TV itself was stellar, Sony XBR8, until one day a couple years ago it just wouldn't turn on anymore. I got 10+ years out of it. It's still in my kitchen waiting to be hauled to electronic recycling (I haven't done so because it's HEAVY for an LCD, but the early LED backlight added a bunch of weight).
