Sorry this video is hard to see the screen. Mostly what you see is the reflections of my camera and the bus I was passing on the 520 bridge as I took this movie. And it's all bouncy and shakycam and stuff. But there's enough there so you can see what I'm talking about.

Note that this is intermittent, you see it kind of fade in and out as it goes. After the player warms up a bit, it's fine except for a few pixels in the bottom left corner. Also, I can make it come and go by pushing on the fascia. So clearly, it's a loose solder joint somewhere on the display board.

The question is, seeing that behavior, which solder point is likely to be the culprit this time?
