i want to know if the screen is bad or the video connector i have reseated it and checked the edges of the led but no luck..
when i browse the internet the unstability increases.
it is wxga hd 1366*768 hp
Nothing has touched my screen no cracks no liquids.
Please answer my question..

The image you sent only shows icons and a black background, which seems to show no color problems.
