Make sure the LCD is not cracked. Sometimes these cracks may not be visible to the bare eye. have you stepped on it, put something on it or anything similar?

Just in case it is your LCD, see if your warranty covers it, if not you are better off buying a new laptop. One of my friends paid $500 on an Acer, he stepped on it, warranty wouldn't cover it and he was asked to pay $400 to have it fixed.

If this is a software problem, I can't think of anything else but the Screen properties, like Colors, or resolution.I can only think this is a hardware problem.

Laptop monitor bad color and flickers continuely, but when attached to external monitor, works fine


I'm going to take an educated guess here, because it sounds like the monitor's interface controller is bad. I forgot the name of the thing, but it's a small circuit board that's normally located at the bottom of the panel frame, between the flat ribbon cables and the round hinge cables.

Lines at bottom of screen on asus x83v


Your lcd screen is going bad or your video card inside the computer is bad. To isolate the problem Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok then your video card is good and the lcd screen on your laptop is bad. If the Borrowed monitor displays the same lines as your lcd screen, then your video card inside the computer is bad.

The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

My computer monitor just turned a red color


  1. A video cable that is not completely seated, it will cause bad colors.
  2. Have you adjusted the color settings on the monitor? That can screw things up.
  3. Could be a bad monitor. Can you install the monitor on another computer to verify that it is OK?
  4. A possibility is a bad video circuit in the computer. A diagnostic program will verify that the circuit is working is not free. Here is a trial version that might do the tests you need: http://www.filehippo.com/download_sandra_lite/
Without having access to your system that is about as good as I can do.

Not true color


I seem to have found the solution (and the cause, perhaps?) for this problem!

I was having the EXACT same problem with a monitor I'm repairing for a friend. The capacitors on the power supply board were blown (CapXon capacitors, who'd've guessed), which was keeping it from powering up. After replacing the capacitors, the screen worked beautifully. But it had this weird yellow tint!

The strange part was that pure colors - red, green, blue - all appeared perfectly OK on screen. Curiously, the menus would show in the proper colors, except for one: the manual color adjustment menu, which illustrated "Blue" as a sort of off-green in the icon. Auto-Adjust would always fix the colors for a split second, then go back to yellow. Reset didn't fix it. Color reset didn't either. So, exactly the same problem as above.

The solution I found was hidden within the main menu itself, a sort of "easter egg". <b>Hold the Menu button down while pressing Power, and hold it down until the screen, and menu, appear</b>. There will now be a hidden selection, "Auto Color", printed in a red-on-black font at the bottom of the menu. Use the +/- buttons to access it, and press Menu. Voila! PERFECT COLOR! Perhaps this menu was accessed by accident, and calibrated to an incorrect color key. But now my picture works great, and the setting lasts through Auto-Adjusts and Resets!
