Acer monitor has green lines on the scren


Liquid Crystal Display (LCD) screens use less energy and display a clearer picture than the Cathode Ray Tube (CRT) displays that preceded them. These new LCD screens now dominate the computer monitor market. From time to time, however, pixels can become stuck and a green line can display on the screen. Removing this line is sometimes possible without sending the screen to the manufacturer for expensive repair.

Locate the pixels that are stuck on the screen. Download a free screen repair software program, such as UD Pixel or JScreenFix. Run the software and allow it to find and attempt to repair the stuck pixels. Turn off the LCD monitor. Apply the damp cloth directly over the stuck pixels and use a gentle pressure to spread the liquid within the screen.

Hp pavilion dv7-4165dx black screen


A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,


if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on.


To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.


Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard.


Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue.


Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue.


Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.


Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.


Slide the battery latch to eject the battery. Pull the battery out of its compartment.


Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard.


Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.


Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector.

Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place.


Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective.

If the external monitor works, the LCD screen could be broken.

If the monitor doesn't work, the motherboard or video card might need to be replaced.


Hope this helps

On my asus Eee Pc 1201HAB the display shifted to the left so the left side is partially cut off, how do i fix it?


1) Looking at the User Manual right now, and do not see a Hot Key on the Keyboard, that shifts the display.

[ Hot Key is also known as Special Key. The F1 through F12 keys at the top of the keyboard, and also for your model, colored keys on the keyboard ]

It could be the Screen Resolution is messed up. Not set at the correct settings.

Right-click on an empty area of your desktop screen.
At the bottom of the drop down list, click on Properties.

In the Display Properties window click on the Settings tab.

The screen pixel resolution should be set at 1366 X 768,

http://www.screentekinc.com/Asus_EEE_PC_1201HAB--12.1-inch--1366x768-wxga_hd-laptop-lcd-screen.shtml

In the middle of the Display Properties window, you see the blue subheading - Screen resolution

Right under this small subheading is a Slider.
The Pointed 'arrow' with the green tip, and top, slides back, and forth on the 'line'.

It should state 1366 X 768.
If it does not;

A) Left-click on that green tipped Slider. Hold the left mouse button down. Move your mouse, and move the Slider. (Drag)
Move it to the Left to Decrease the screen resolution, or to the Right to Increase the screen resolution.

Can't set it to 1366 X 768? Post back in a Comment.
ALSO, the Color Quality should be set to -
Highest (32 bit)

If not click on the blue down arrow to the right of this box.
In the list left-click on Highest (32 bit)

Now go below to the right, and click on Apply.
After go below to the Left, and click on OK.

Still no joy?
Believe the problem is hardware related.

Could be something as simple (?) as a bad Video Cable.
(Goes from the motherboard, up under the left Hinge, and then up into the Display Assembly)

Could be the screen Inverter.

However the Eee PC 1201HAB is supposed to use an LCD panel, that has qa series of LED's for backlighting.
Newer backlighting that uses a series of LED's for the Backlight, doesn't require a screen Inverter.

There were some LED backlit LCD screen, that DID use a screen Inverter. Mostly the older models of laptops.
This is what makes me think your LCD screen's Backlight, (And LED), may use a screen Inverter,

http://www.batterystyle.com/asus-eee-pc-1201hab-screen-p-168219.html

Scroll down,
"5. Disconnect the power cable and video cable from the Asus EEE PC 1201HAB Lcd panel. The power cable connects the screen's power source, the lcd inverter, to the backlight lamp attached to a side of the panel."

Probably just a generic form, and didn't take in consideration that the Eee PC 1201HAB netbook, uses a series of LED's, as a Backlight.

May not have a screen Inverter.

To explain;
Primer:

An LCD screen cannot produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

(Click on the window with the computer monitor in it )

It needs an additional light source. A Backlight is the additional light source.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.

[ LED = Light Emitting Diode.
CCFL stands for Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

{Average thickness of a CCFL bulb is 2mm. That is a a little larger than 1/16th of an Inch.
The average length is almost as long, as the LCD screen is in height]

A screen Inverter is used to CONVERT the power from the laptop, for the LCD screen, and Backlight.

Do not see any listings for an Asus Eee PC 1201HAB netbook, for a screen Inverter. Believe the LCD screen uses LED's for a Backlight, and does NOT use a screen Inverter.

Which means if the problem is in the Display Assembly, the LCD screen itself will need to be replaced.
The LED backlighting is built-in.

[Hmmmm, I see a trend going on here that I do not care for, and just woke up to it. Have to replace the entire LCD screen, and cannot just replace the Backlight, or screen Inverter? Sounds like Ka-ching $$$$$ for somebody!

A screen Inverter usually averages from $20 to $40+.
A Backlight ( CCFL) usually ranges from $10 to $15.
An average LCD screen can range from $80 to $300+.]

How to know if the problem is in the Display Assembly?
Use a VGA monitor, and connect it to your laptop.

A) Laptop OFF, monitor OFF. Connect a VGA monitor's cable to the VGA port on the laptop.
(Left side rear. This is an example of a VGA Cable, and VGA connector { Port on a computer },

http://en.wikipedia.org/wiki/VGA_connector )

You can use an older CRT type of VGA monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable attached.

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By default the display should automatically show, on the external VGA monitor.
IF not;

There are at least three display options:
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and hold it down. At the same time tap once on the F8 key.
The F8 key is the Display Toggle-Over key.
(Give it a few seconds. Sometimes it doesn't happen right away)

Still no?
Hold the Fn key down again, and tap once more on the F8 key.

Is the display off to one side on the external VGA monitor?

Dual screen wont work


Kevin,

1) You cannot plug a monitor into the VGA connector, on the back of the desktop computer, AND plug a second monitor into a DVI connector, on the back of a desktop computer.

In otherwords you can only plug ONE monitor into the motherboard.

[ The I/O area on the back of the desktop computer, is the Input/Output area. This rectangular area has connections for Input devices, and Output devices.

Examples such as a Mouse, Keyboard, (INPUT), VGA devices, (VGA monitor - Output), USB devices, audio devices, (Speakers - Output. Microphone is an Input device), and so on.

The I/O area has a rectangular metal shield. (Thin metal plate)

Connecting a device in the I/O area, is connecting it directly to the motherboard.

Example of a VGA connector, and VGA cable,

http://en.wikipedia.org/wiki/VGA_connector

Example of a DVI cable, and DVI connector,

http://en.wikipedia.org/wiki/Digital_Visual_Interface

(There are several variations of DVI connectors.
Scroll down ]

To use dual monitors you need a graphics card also.
Graphics card with a VGA connector, or DVI connector. (Or both)

Monitor with VGA cable, plugs into the I/O area on the back of the desktop computer. (Plugs into the motherboard's graphic chipset)

The second monitor plugs into the graphics card's DVI connector, or VGA connector.

[ Just an example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1416091&CatId=3669

On the image of the graphics card on the left;
Go under it to the subheading - + 11 larger images and views.

There are 7 views shown. One is the carton the graphics card comes in. (View 2 from the left)

Going from the left side, count over to the 5th view. Left-click on the 5th view. Shows you the 'business end' of the graphics card.

Starting at the left side it is the HDMI connector, then VGA connector, then DVI connector.

Note*
YES, you can plug a VGA monitor, AND a DVI monitor, into this type of graphics card, and have Dual monitors ]

FIRST:
Computer on, Windows running; Put the Installation disk (CD) in the optical drive's tray. (CD/DVD drive)
Load ALL software.
Drivers, and 'Control Panel'.

Graphics card software loaded, close all windows, go back to your desktop screen. Turn the computer off normally.

Unplug the computer from power. Open the computer case.
FOLLOW Anti-Static Precautions.
(Don't know Anti-Static Precautions? Post back in a Comment)

Physically install the graphics card. Close the computer case.
Plug the VGA cable of the Primary monitor, into the VGA connector in the I/O area, on the back of the desktop computer.

Now plug the DVI cable of the Secondary monitor, into the DVI connector on the graphics card.

(The main monitor you use is the Primary monitor. The second monitor you are going to add, is the Secondary monitor )

Plug the computer into power. Both monitors plugged into power, turn them BOTH on.
Turn the computer on.

When Windows loads you will see a display on the Primary monitor.
Your desktop screen.

Now Right-click on an empty area of your desktop screen.
In the list at the bottom, Left-click on - Properties.

In the Display Properties window that comes up, left-click on the -
Settings tab.

You will see two rectangular icons. 1 and 2.
1 is the Primary monitor. 2 is the Secondary monitor.

Left-click on the Secondary monitor icon.
Go down towards the bottom/middle on the left.

Left-click in the empty square to the left of -
Extend my Windows desktop onto this monitor

Go down to the bottom Right. Left-click on Apply.
Go down to the bottom Left. Left-click on OK.

Your desktop screen will now be on the secondary monitor.


When you open your internet browser, (Yahoo, or Google, or MSN, or Mozilla Firefox, etc), you have to DRAG the screen onto the secondary monitor.

(Let's use Yahoo for an example. Yahoo will be on your Primary monitor.
You need to drag Yahoo onto the Secondary monitor)

Which direction you drag, is up to which direction the two monitors are sitting, on your computer desk.

The way the monitors are sitting in Display Properties; the Primary monitor is on the Left. ( 1 )
The Secondary monitor ( 2 ) is on the Right.

This is the way the two monitors should sit on your computer desk.
(There is a way to switch them around, however)

On your Primary monitor, (Still using Yahoo as an example), go to the RIGHT side. See the blue frame going around the screen?

When you bring the mouse cursor ON the blue frame, it turns into a Double-Sided arrow.
It is difficult at first to keep the cursor as a double-sided arrow.

Move too far to the right, it turns into the usual pointed cursor.
Move too far to the left, and it turns into the usual pointed cursor.
have to keep it on the blue frame.

WHILE the mouse cursor is a Double-Sided arrow, left-click, and hold the left mouse button down. Now drag the screen to the Right.
(Move your mouse to the right)

Keep dragging until the Yahoo browser is on both monitors.

Different size monitors? The display will not be the same size, on both monitors.

[ I use an HP 2009m, 20-inch widescreen monitor, as a Primary monitor, and an RCA EN-V, 26 inch HDTV, as a Secondary monitor.

I have my desktop on the Primary monitor, and FixYa, (Firefox browser), on the Secondary monitor, right now ]

If this is not your problem please state in a Comment.
Also state additional questions in a Comment.

I have a Dell Inspiron 531S, I have both two different monitor slot, does my PC support dual monitor systems?


Yes.

The area on the back of the computer, that has two ports to connect a monitor, is a Graphics Card.

It is a PCI-Express graphics card, and is plugged into a PCI-Express x16 slot on the motherboard.
(Expansion Slot)

It has a blue VGA port, white DVI port, and black S-Video port.

The area on the upper left with a blue outline around a VGA port, is a VGA port connected directly to the motherboard. It is Integrated Graphics.

You CANNOT use Integrated Graphics, and a graphics card at the same time.

It's either use the Integrated Graphics VGA port, OR use the graphics port/s on the graphics card.
BIOS will Not support using both Integrated Graphics, and a graphics card.

HOWEVER, you can use the VGA port, and the DVI port when using two monitors.
You will be only using just the graphics card.

Example of a VGA port, (Connector), and VGA cable,

http://en.wikipedia.org/wiki/VGA_connector

Example of a DVI port, and DVI cable,

http://en.wikipedia.org/wiki/DVI_connector


1) Whatever monitor you have that has a VGA cable, plug it into the blue VGA port on the graphics card.

(There are VGA monitors {CRT} that resemble a small TV. VGA cable is usually attached.
There are also LCD flat screens that have a VGA connector, for a VGA cable, and may also have both a VGA, and a DVI connector.

To digress for a moment;
VGA is Analog. It uses an Analog video signal.
DVI is digital. It uses a Digital video signal.

A computer naturally puts out a digital video signal. This digital signal has to be converted by the computer, into analog for an analog monitor. This slows the graphics process down. This is one reason it is best to use digital )

2) Plug a monitor with a DVI cable into the white DVI port on the graphics card.

3) Turn the monitors on.

4) Turn the Inspiron 531s on.

5) When Windows has loaded, right-click on an empty area of your desktop computer screen.
Now left-click on Properties at the bottom of the list.
Left-click on the Settings tab.

6) You are now looking at a small window that has two monitor icons in it.
Monitor 1 icon, and monitor 2 icon.

Monitor 1 icon is your Primary Display.
Monitor 2 icon will be for the Secondary Display you are adding.

Note how monitor 1 icon is sitting to the Left, and monitor icon 2 is sitting to the Right.
This is how your monitors are supposed to be arranged on your computer desk.

If the second monitor is on the Left on your computer desk, you need to move the icons around.
Move monitor 2 icon to the Left.

Left-click on the icon, hold the left mouse key down, and drag the monitor 2 icon over to the left side of monitor 1 icon. (All the way over, or it will snap back to where it was)

It may matter to you how your monitors are arranged. It may not. Once you read the following it may help you decide.

7) Left-click on monitor icon 2 if you have not already done so.
Go down to where it states, "Extend my Windows desktop onto this monitor"

8) Left-click once in the empty square, to the left of Extend my Windows desktop onto this monitor.

9) Now left-click on Apply at the bottom Right corner.

10) Finally left-click on OK at the bottom Left corner.

You should now see your desktop screen on both monitors.

When using the internet on both monitors, you have to drag the screen from the Primary monitor to the Secondary monitor.

Go to the left side of the screen. Left-click right on the edge of the blue frame. Hold the left mouse key down after you click, and drag the screen across to the left.

Doesn't work?
Go to the right side, click on the blue frame, and drag the screen to the right.

This is why it may matter how the monitors are arranged on your computer desk.

It's kind of eerie your first time dragging the screen across.

You will also find out why it is best to use two similar monitors, when using dual monitors. The pixel resolution is different for both monitors, if they are different from each other.

For additional questions please post in a Comment.

To joecoolvette reguarding 2005 compaq presario SR1000 and Dell LCD TFT monitor. The dell monitor was part of my mothers comp and I wasnt given a CD with it. Im sure she dont have it now. As far as the...


jason,
When a device is installed, Windows 'Breaks it's neck', to find a compatible driver, (Or drivers)

If THE driver is not present, then Windows will match up one of it's thousands, of generic drivers it has on hand.

Then if THE driver is installed, there is a driver conflict.

{Crude illustration}
Windows: 'Which drivers do I use? These or THESE?'

Let's try this;

{Based on Windows XP operating system}
1) Left-click on,
Start>
Control Panel>
Add/Remove Programs

When Add/Programs populates REMOVE the graphics cards software.
ALL of it. Anything you see associated with that graphics card.

Close all windows, go back to your desktop screen.
(If you are asked in Add/Remove Programs, if you wish to restart your computer - NO)

Shut your computer down normally.
(Start>Turn Off Computer>Shut Down)

Unplug your computer from power. Open the computer case, TOUCH the metal frame to relieve your body of Static electricity.
(Static will fry out your computer hardware components)

Remove the graphics card.

Press the Power On button in, and hold it in for a count of Five seconds. (And I mean Five. Count - 1001..1002..1003..1004..1005)

Let go of the Power On button.
Do this same procedure Two more times. (Imperative!)

What you are doing is clearing CMOS Error Codes, and resetting your BIOS Setup back to the factory default settings.

Now plug your monitor into the VGA port on the motherboard.
Plug your computer back into power.
WAIT 1 minute.
Turn your computer on.

When Windows has loaded all the way, put the CD disk for your graphics card in your optical drive tray. Load the software.

When you are finished, close all windows, go back to your desktop screen.
Shut your computer down normally.

Unplug your computer from power. TOUCH the metal frame. Install your graphics card.
Plug your monitor into the graphics card.
Close your computer case.

Plug your computer into power. WAIT 1 minute.
Turn your computer on.

If the resolution isn't correct:

Right-click anywhere on an empty spot of your desktop screen.
In the drop down menu, Left-click on Properties.
Now left-click on the Settings tab, all the way to the right.

Look down at where it states - Screen resolution, in blue.
(Halfway down the Display Properties window)

Is the pixel resolution what it should be?
If not, Left-click on the slider.

Hold your left mouse button down, and slide the slider, to where the resolution settings are correct for your Dell LCD monitor.
(To the left is Less. To the right is More)

Now go down to the right, and click on Apply.
Then go over to the left, and click on OK.

Don't know what the native resolution, for that Dell LCD Thin Film Transistor monitor should be?

Look it up on the internet using the Model Number, or give me the Model Number, and I'll look it up for you.

My emachines monitor has no picture, hard drive is functioning properly. Monitor is black


if you do not get a screen with a LCD monitor its likely you have a inverter problem or BACKLIGHT problem. you might need to replace the LCD backlight or replace the monitor on the desktop.
check to see if the laptop can get a picture by plugging in a monitor to it, im sure theres a connection for external monitor.

theres also a FN (function key) command to switch from lcd to external monitor. always test before commiting to replacing a monitor.

The desktop, you might want to test another monitor on the desktop just to be sure the monitor is gone or dead. if you see on the monitor a OSD saying "No power or No Signal" or you can pull up the OSD(on screen display menu). then the monitor is not dead.

might be the computer even though the computer powers up doesnt always mean the computer is working.

i would check the motherboard for blown capacitors or funky smelling(burnt plastic)aroma. Make sure the computer is off before checking.

get back to us!

thanks
