Bad laptop display or display connector? (Lenovo Y560p)

post #1 of 3
Thread Starter 
Is there an easy way to differentiate between whether my display is bad, or if it's my video connector to the display?

My laptop (Lenovo Y560p) display has distorted coloring evenly across the entire image. I can tell it's either the display or the connector, as I can plug in external monitors and they work flawlessly. Also, if I use take a screenshot there is no distortion, so that rules out the gpu.

If I move the display back and forth it will change the way the color is distorting... Sometimes it's a blue speckle overlay, or differing severity. And sometimes it's an extreme purple or red speckle overlay. Sometimes the display works just fine however, giving perfect color quality. Also. the color distortion sometimes changes when nothing has touched the laptop at all.

If it works sometimes, but not others, then I would try making sure the display connections are properly seated. This would require taking apart the laptop to some extent.
