Laptop screen problem

[ShadowReaper]

Hello,

I have a problem with my laptop's screen. The colors seem washed-out. I am pretty sure that the problem lies in the LCD screen but I would like your opinion.
1)I tried connecting an external monitor with both VGA and HDMI and the external monitor works fine
2)I replaced the lcd cable but the problem remains

I uploaded 2 photos from the screen http://imgur.com/a/3MZWF

When they start getting a little pinkish tint, and colors look washed out, the LCD is about done. Time for a new one..

You may be approaching the time to swap out your CFL backlight tube. What model and vintage is your lappy?

Also, I am moving this thread to the Notebook Forum.

Thanks for the answers,
the laptop is a Lenovo Y560 and the screen is LED, so there is no inverter

Last question - what OS? Since it displays correctly externally, it would appear to be a laptop only problem, and that leads to what Burpo said. But, it wouldn't hurt to check the drivers.

Can you hook up an external monitor? If an external monitor also has the same problem the issue is with the video card. If the external monitor looks fine the issue is with the laptop's display or connections to the display.
