I know this question has been asked somewhere in this thread, so I apologize in advance for asking it again.
I had a 70P with the dark clouding issues and vizio replaced it. No muss, no fuss.
But right before they came and got it, I noticed that sometimes I'd see a small line, probably only a pixel or two wide, start at the middle of the screen and rise to almost the top and then stop. The line looks like two pixel's worth of static, stretched across the width of the screen.
When it stops moving near the top, everything below the line is fine, and everything above is ghosting, as if it's a frame or two ahead or behind.
I thought, oh well, you're getting a new one anyway and didn't say anything. But now my new one is doing it too. It only happens occasionally, and when it happens, it happens on every input. I've swapped inputs and cables to no avail, so I think it's screen related.
I thought I read a post awhile ago from someone else with this issue. Thoughts? Could it just be a HDMI handshake issue that affects every input? TIA!
