Other models can detect the monitor but display image only on one screen internal or external. If both, the internal screen and external monitor or TV show strange or incorrect colors or any other image distortion, this is the graphics card failure.

If only the internal screen shows bad video but external image appears to be normal as in my examplethe problem is somewhere inside the laptop display.

The screen receives data signal from the motherboard via LCD cable. If the LCD cable not making good connection with the motherboard, it might cause image or color distortion on the screen. Try reseating the LCD cable connector and see if it fixes the problem. Make sure the LCD cable connector plugged correctly.

A pinched or damaged wire inside the cable also can cause color distortion. Wiggle the cable while the laptop is running.

OK, my laptop started showing some random characters all over the screen. The characters appear when I turn on the laptop on the background where logo displayed and it looks like these characters forming vertical rows. After reading your post I decided to test it with my desktop monitor and found that external image also has same characters and some strange lines. Does it mean the video card is bad? Yes, it sounds like the graphics card failure.

In most laptops the graphics card integrated into the motherboard and cannot be removed or replaced separately. Probably not worth repair. A screen may show wrong colors if it has been constantly exposed to an adjacent magnetic field effect such as music system speakers. This problem is so difficult to fix.

How important is the version number on the replacement screen if the rest of the number is correct? I have found a BEW01 V. You should contact the seller. A screen with different version number could be different. Once I purchased a new screen with same model number but different version. The new screen had different mounting bracket locations.

Are the colors "off" somehow on your computer's screen? Maybe they're washed out or inverted? Perhaps everything has a red, green, or blue hue, or even just too dark or too light? Worse yet, and easily the root cause of those migraines you've been having, is your screen distorted or "messed up" in some way? Are text or images, or everything , blurry or moving by themselves?

Your computer's screen is the main way you interact with it, so any minor issue can quickly become a significant one.

If the problem happens to be one of the more disorienting issues, it can potentially be a health risk. There are several reasons why your monitor might distort images or represent color improperly, resulting in whatever specific issue you see, so let's walk through some troubleshooting until we figure it out. Most of these are easy things to try, but a few of these tasks might be more difficult or unfamiliar than others.

If so, take your time and be sure to reference any instructions on other pages if you need extra help. Power off the monitor, wait 15 seconds, and then power it back on. Some issues, especially very minor ones, can be caused by very temporary issues with your computer's connection that a restart will fix.

If the problem goes away but quickly returns, especially if it's color-related, try leaving the screen off for 30 minutes before powering it back on.

If that helps, your monitor may be suffering from overheating. Restart your computer. There's a slight chance that an operating system issue is the cause of the discoloration or distortion, and a simple restart will do the trick. Restarting is an easy thing to try early in the troubleshooting process. Check the cable between the monitor and the computer to make sure that each end is physically secure.

Completely unplug, and plug back in, each end to be sure. Newer interfaces, like HDMI , often "push" in and "pull" out, meaning gravity can sometimes eventually work them loose from both the monitor side and the computer side. Degauss the monitor. Yes, this is very much some "throwback" advice, considering that magnetic interference, which degaussing corrects, only happens on those large CRT monitors of yesteryear. That said, if you're still using a CRT screen and the discoloration issues are focused near the edges of the screen, degaussing will most likely fix the problem.

Using your monitor's adjustment buttons or onscreen settings, find the preset default level and enable it. This preset should return your monitor's many settings to "factory default" levels, correcting any color issues caused by settings.

If you have an idea about what's "off" with your colors, feel free to manually adjust individual settings like the brightness, color balance, saturation, or temperature, etc. Adjust the color quality setting for the video card. Setting it at the highest level possible will often help resolve issues where the colors, especially in photos, appear incorrect. Fortunately, newer versions of Windows only support the highest color options possible, so this is probably a worthwhile thing to look into only if you're using Windows 7, Vista, or XP.

At this point, any significant discoloration or distortion problem you're seeing on your monitor is probably due to a physical problem with either the monitor itself or the video card.
