Display screen My acer aspire display screen has two black spots and a line across it.

More than likely the screen Inverter, Anowarul.

However the problem should be diagnosed.

Problem can be;
1) Graphics chipset
2) Video Cable
3) screen Inverter
4) LCD screen

I have a diagnostic flowchart you can follow, if you wish.

The plastic frame in front the LCD screen is the Display Bezel.
(Acer? LCD Bezel)

Once removed the screen Inverter is right there in front.
Mounted to the bottom of the LCD screen's Screen Frame.

Go to where it states - Aspire 1200 (1200 in Blue)
Drop down to the 7th line. (5310G)
Scroll across, and click on 5517.

open control panel in my computer then open display and look for display sync or add display use the add display wizard hopefully this is helpful

you need to adjust the refresh rate of the screen if it is a desktop monitor simply press the menu button on the monitor and go through thee adjust display settings or if it is a laptop go to the run bar and search for display settings

Yup sounds like a typical graphic chip failure unfortunately, especially if it is also on 2nd monitor. :(

Hi friend,

You should check your power...then if display wont come on screen you need to contact computer hardware eng. they repair it...

Upon loading press F2 or del to enter bios setup and change the settings to display the acer welcome screen and the one you said about Microsoft logo and white box with green lines, you cant by pass it because it's windows loading screen

Have your laptop check up the technician, it has somethingt to do with your video card

Can you see, like, a "shadow" of the desktop if you hold a flashlight up to the screen? If so the backlight on your display has burned out and you need to replace your display screen.

Try reinstalling the Display
driver

Try connecting your laptop to an external monitor.Connect it with a vga cable to your monitor and press Fn+ monitor key(I don't know what it is for acer) to switch displays.If there are no lines on the external monitor then the problem is due to the notebook lcd.If there are lines then it is due to a driver.Reinstalling the driver should fix that then.
