Blue line running down the laptop screen..

[vin786]

Hi guys.. I have this thin blue line running down the middle of the screen of my 4-year old Compaq Presario Laptop. It appeared out of nowhere around 2 weeks back and now a second line similar to that has appeared on the right side as well. What could be the reason? Any immediate solution that would be possible from my end? Grateful for any suggestions or recommendations from the forum.

Does display on an external monitor have the same lines (probably not)
unless vidoe chip /adapter problem.Worthwhile doing a video driver update and a memory reseat. Could just require require the LCD cable to be replugged to main board but most likely defective LCD
