I just hope I do not fry the other monitor as that would be another expense.

IMHO, not very likely.

Is it possible there is a bad connection between where the laptop folds down?

That's a big possibility. In fact, I have an old HP Pavillion laptop that has two coloured vertical lines on the right side of the screen. I'm assuming these are dead rows of pixels. I was able to trace the cause in my careless use of the screen itself, I used to open it too much, to a point where it should've stopped, it was almost 180° relative to the laptop! I first noticed one line appear, thought nothing of it. The other one appeared, and after that I stopped spreading that poor thing, and no more lines have appeared.
