Laptop LCD/Display Problem, Green and Pink Tints???

Their are a couple things that could be causing this, My first thought is that the screen its self is damage. A LCD screen is composed of millions of tiny pixels so when some fails others will still work.
That other thought is that the GPU or video device on the laptop could be failing and creating video problems. Have you tried closing the laptop and opening it agian, this would help rule out a bad cable connection.

Yellow screen

You could try re-installing the graphics drivers, but it may be more serious, you may need to take to a local tech for testing as it could be 1 of 3 possible faults, graphics chipset, LCD/LED display or the LCD/LED display cable, let me know what happens. good luck.

White color in LCD monitor appears as pink anywhere ! but sometimes it back to white color truely.


This can be a common problem with laptop screen when white goes pink. This is caused by a faulty cable that runs from the laptop motherboard to the inverter just under the screen.

The cable becomes stretched after a while by movement of the laptop lid which pulls a pin from the cable.

What i suggest you do is take the laptop to PC repair store and have them fit a new video cable or order a replacement video cable from eBay and replace the cable yourself.

Don't be fooled by the preconception that its a bad CCFL bulb (backlight) as this is not the case.

Asus x83v monitor has a red flickering bar across the lower part of the lcd it is as thick as the task bar thats why i have to place the task bar on the top, its like a static flickering red to pink and...

The display hardware is damaged. Most likely you will need to replace your screen. In rare instances, this can be caused by a loose ribbon connector from the display to the display adapter board.

Screen is disclored.Shows pink instead of white.

Possible bad connection on the LCD cable. Check and reseat the cable on both end( the cable to the laptop and the cable to the LCD panel). If that doesn't work you will need to replace the cable.

Toshiba Satellite L35 screen color turned to pink.

If you have a LCD-screen, not an old-style CRT-screen, it is the data-cable, and its connections, that are not transmitting one of the 3 "primary" colours, e.g., mix red & blue & green to get white,
but mix only two of those colours, and you could get pink,
because the mixing is an "additive" process.

If you mix NONE of the 3 primary colours, you should get BLACK.
If you see GREEN, you're seeing ONE of the primary colours.

Asus x83v screen is black and has vertical lines on half of it.

As the product is under a year old it should be covered under warranty. Get in touch with asus customer services before you let anyone attempt a repair as doing so may invalidate your warranty

Screen goes pink

First, plug a external monitor and toggle the screen to discard configuration or software problems. If the image displays correctly you have a problem either in the LCD screen or its connection cable.
Open the bezel and check for loose or damaged connection cable. Look specially next to the hinge, ON THE LEFT.
In case the problem is not the cable you might have to get a new LCD. You can have replacement parts and instructions here:

Pink screen

Dear LT user,

Your LT has one of the following 2 problems: Your LCD cable might be faulty OR your inverter board is malfunctioning.

The LCD cable is responsible for transfering "color information" or "screen data" from the motherboard to your screen. If this cable is faulty or malfunctions, it can result in a lot of appearances - in your case a pink screen.

The Inverter board is repsonsible for the "light" on your screen. If the inverter board is faulty or does not function properly, you might experience this issue.

If your LT is still under waranty, you can give it in @ the nearst HP Warany centre for repairs. If not ; HP parts are very expensive.

What you can also do, you could install an external monitor (LCD flatscreen) to your LT. Because the Flatscreen cable connects to your VGA port at the back of your LT, using an 15 pin blue connector , it connects directly to the Mainboard so it does not run over the LCD cable and thus will be a unit on its own.

Kind Regards,

Toshiba portege s100-s1133 lcd screen

A pink or red screen which may gradually turn back to it's appropriate color indicates the lcd is going out. It could last quite some time in tht condition, but it's going. replacement isn't too bad though.
good luck
