I have an interesting one for you. It is a LG 47LD450-UA with a yellow vertical line. It has two particularities:
1. The yellow line starts 3 inches from the top edge and goes all the way to the bottom of the screen.
2. From the start at 3 inches from the top edge, the yellow line is composed of alternating green and red pixels. In other words, all odd pixels are green and all even pixels are red.
It cannot be a tab bonding issue since the line begins at 3 inches from the top edge (the ribbon connectors are at the top).
Can it be a shorted pixel that messes up the remaining of the line? But why does it alternate between green and red pixels?
The other possibility is a bad video memory chip.
What do you think?
