Replace lcd on gateway NV57h77u


I disagree. The procedure is so easy no Service Manual is needed

1) Remove ALL power. Remove the AC adapter, and Battery.

2) Open the laptop.

The plastic frame in front of the LCD screen is the Display Bezel.
(Gateway? Believe they call it the LCD Panel Bezel)

Down in the BOTTOM corners, next to the Hinges, are screws to be removed. One in each bottom corner.

There are Screw Covers over these screws. The Screw Covers need to be removed.
Little round covers I believe to be made of plastic.
(Some models they are made of synthetic rubber)

I use a computer pick to Gently remove them.
Some use the tip of an X-Acto knife. I do not recommend this as there is a possibility of injury.
Perhaps a large darning needle. (Needle you sew with, but is Large in size)

Pick up at one edge of Screw Cover. Screw Covers are held on by a type of rubber cement.
I LIGHTLY stick them to the Display Bezel for safekeeping.

(Yes. They like to stick to the tool, your fingers, and it seems passing jets in the sky.
If you are careful with them, you should be able to reuse them.
If they do not stick anymore, use a toothpick, and apply a TINY dab of rubber cement to them/it )

Once the Screw Covers are removed use a No.1 Philips screwdriver, or equivalent Jewelers screwdriver; to remove the 2 screws.

The Display Bezel has TABS going around the exterior perimeter, of it's inside edges.
These Tabs snap into matching LATCHES on the Display Cover.

You can come from the Outside edge, where the Display Bezel meets the Display Cover, and use a thick guitar pick.

The guitar pick is wedged into the parting line, of where the Display Bezel meets the Display Cover.

Once a 'crack' is formed in-between the two, then the fingertips are used to gently start popping the bezel from the cover.

You slowly go along with your fingertips, and work along the top, then sides. By the time you have both sides almost loose, the Display Bezel usually pops off.

I like the flex method.
Come to the inside edge of the Display Bezel.
Where it meets the LCD screen. I suggest start on the Right side/Middle.

Use a fingertip, and lift up the inside edge of the Display Bezel up a little. Can't lift up at that spot? Move over. You are at a Tab/Latch.

With this spot lifted up a little, use the fingertip of the other hand, and slide under next to it.
Now use your fingertips as wedges, and pop the Display Bezel loose a little at a time.

I start at the Right side/Middle as stated. Left hand fingertips go DOWN the right side, Right hand fingertips go UP the right side.
Then I go across the Top, and down the Left side.

MOST of the time, as stated; the Display Bezel usually pops off when right side, and left side are most of the way popped loose.
NOT always though!

Sometimes you have to pop EACH and EVERY Tab/Latch loose.

Also; watch around the Hinge area/s.
Display Bezel can get hung up around them.
Go slow, and gently work the Display Bezel off, around the Hinge areas.

Display Bezel popped off, sit back; relax. You just did the hard part.
Wasn't so tough, huh?

This is what the Display Bezel looks like removed,

http://www.ebay.com/itm/Gateway-NV57H15U-LCD-Front-Bezel-15-6-AP0HJ00021-/171020787909?pt=LH_DefaultDomain_0&hash=item27d1a220c5

The MAIN view shown is a BACK view.
In the smaller views underneath, the 4th view from the Left, shows the FRONT view.

If you SET your mouse cursor in the middle of the Main view photo, the Zoom In feature is enabled.
You can CLICK on any of the smaller views, to make them appear as a Main view.

You can also see that the Hinge Covers, are an integral part of the Display Bezel. Shows you that when removing the Display Bezel, these Hinge Covers may need to be worked off of the Hinges.

Of course, may not; as I have previously stated.

The LCD screen is an Assembly. It is composed of layers.
These layers are kept in the factory set alignment, by a metal Screen Frame.
The Screen Frame resembles a picture frame.

There are THREE screws on each side of the Screen Frame.
These screws (Philips) go through metal Brackets, and hold the LCD screen/Screen Frame; to the Display Cover.

The Brackets are an integral part of the Hinges,

http://www.ebay.com/itm/Gateway-NV55-NV57-LCD-Left-Hinge-Rail-Bracket-AM0HJ000100-/400334888754?pt=LH_DefaultDomain_0&hash=item5d35d19f32

On EACH side, there is 1 screw towards the Top, 1 screw towards the Bottom/Middle, and 1 screw towards the Bottom.

Remove all 6 screws.

At the Top is the Webcam Cable. Unplug it from the Webcam Module.
(Cable pulls to LEFT side, facing laptop)

The TOP of the LCD screen is now tilted forward.
The Video Cable plugs into the Bottom side.

There should be a piece of clear Mylar tape, holding the Video Cable connector in place. Carefully peel it back, unplug the Video Cable from the LCD screen.

Remove the LCD screen.

Reverse steps to install new LCD screen.

Acer 5535


http://www.fixya.com/answerpage.aspx?erc=8&thid=16230193

Watch posting two posts for the same problem, and not putting the Full information in the second one, as you did on the first one.
As in this one.

Original question is why is the screen Pink.

Primer:
An LCD screen cannot produce light,

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

(Click on the monitor icon )

Therefore an LCD screen 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.
(Light Emitting Diode)

A CCFL is a Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
Average thickness of the bulb is 2mm. That is a little more than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.

LCD screens for the Aspire 5535 series of Notebook PC's, show either CCFL backlighting, or LED backlighting.
My Aspire 5535 uses LED backlighting.

A laptop using CCFL for backlighting uses a screen Inverter.
General rule for LED backlighting is that No screen Inverter is used.
In reality it depends on the laptop. When LED backlighting first came out, a screen Inverter was used. As time progressed no screen Inverter is used.

A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen, and Backlight.

Primer over.

You need to check if the problem is the graphics chipset, or Video Cable, or inside the Display Assembly.

(Inside the Display Assembly: Screen Inverter IF used / LCD screen)

The Switch Cover is the plastic cover above the Keyboard, and below the LCD screen. Has the Power On button, and status indicator LED lights in it.

Acer's term for Switch Cover is Middle Cover.

The Video Cable is LCD Cable.
The LCD screen is LCD Panel.

The Video Cable connects to the motherboard, in an area under the Middle Cover.
(To the right of the Left Hinge)
It then routes through the left Hinge, and up into the Display Assembly. (LCD Module)

From there a separate small cable. comes off the main Video Cable, and connects to the screen Inverter.
IF a screen Inverter is used.
The main portion of the Video Cable, then connects to the back of the LCD screen.

Just due to repeated normal opening, and closing of the laptop; the Video Cable may become pinched, and pulled on.
This can lead to loose connections at motherboard side, and/or screen Inverter, and/or LCD screen side.

A loose Video Cable connection can cause what you are seeing.

Also due to being pulled on the Video Cable may receive damage.
Stretched/Broken wires.

The procedure is to remove ALL power, remove the Middle Cover, and PHYSICALLY check to make sure the motherboard side connection of the Video Cable, is plugged in tightly.

Visual inspection alone will NOT do.

[Middle Cover is supposed to be just that. A Cover.
If it has the Power Button Board, and LED indicator lights attached to it, try to lay it aside when tightening the motherboard connection, of Video Cable.
This way you do not have to reattach it's wires, to check if motherboard connection was the problem ]

Once the motherboard side of the Video Cable is checked for tightness, the power can be reinstalled; and laptop turned on, and checked.
(AC adapter [ Charger ] and Battery)

Tightening motherboard connection of Video Cable does no good?
On to the LCD screen side, and screen Inverter. (IF used)

The plastic frame in front of the LCD screen is the Display Bezel.
Acer? LCD Bezel.
The Display Bezel also has the Hinge Covers attached to it.
I do not believe the Display Assembly (LCD Module) has to be removed, in order to remove the Display Bezel. (LCD Bezel)

There are 4 Philips head screws to remove from the Display Bezel.
These are under Screw Covers.
One in each corner;
Top Left, Top Right, Bottom Left, and Bottom Right.

The Screw Covers are made of synthetic rubber, or plastic.
They are gently pried up from the bottom edge of them.
I use a computer pick.

If you are careful you can reuse them. I LIGHTLY stick them to the Display Bezel for safekeeping.
(They like to stick to Everything! Your fingers, the computer pick, and passing satellites)
They have a type of rubber cement that holds them on. If needed you can apply a TINY dab of rubber cement with a toothpick.

Remove the 4 screws.
The Display Bezel has TABS going along the perimeter of it's inside edges.
These Tabs snap into matching LATCHES on the Display Cover.
The Display Bezel is also flexible.

I cover the LCD screen for protection, with a piece of thick construction paper cut to just fit the inside edges, of the Display Bezel.
Then slightly lift the INSIDE edge, of the Middle, of the Right side of the Display Bezel.
Come to the middle/right of the Display Bezel, and inside/LCD screen side.

Lift the Display Bezel up a bit. Can;t slide a fingertip in?
Move over. You are at a Tab/Latch.
With a fingertip underneath, use the other hand, and slide a fingertip under also.
Slide down until you reach a Tab/Latch. It should pop open. SNAP!
Sounds like you are breaking something.

Keep moving down towards the Bottom. Keep popping the Tabs/Latches loose. Move towards the Left side.
Once the Display Bezel has popped most of the way loose, it should then come all the way off.

IF a screen Inverter is used, it should be mounted at the bottom of the LCD screen. It's a small green circuit board. One small cable will come from the Video Cable, and plug into it. (At the top is the Webcam, IF used)

The LCD screen itself is an assembly. It is composed of layers. You saw this in the 3M video.
The layers are held in the factory set alignment, by a metal Screen Frame. Looks like a picture frame.

There are two Brackets.One Bracket on each side of the LCD Screen Frame.
The LCD screen, and Brackets are removed as one unit.

HOWEVER, the LCD screen is NOT to be removed all the way. It is just tilted forward enough at the Top, to access the Video Cable connection on back of the LCD screen.

LCD screen connection checked, and this does no good, then remove the Video Cable.
The Video Cable needs to be checked for Continuity.
Every wire needs to be checked to see if electricity goes through.
If not this means there is a stretched/broken wire.

Check with a multimeter set to OHM's. (1K)
Check every wire. Also have an assistant gently wiggle the middle of the Video Cable. An intermittent reading on the multimeter indicates a broken wire.

No multimeter available? Suggest take the Video Cable down to the nearest small computer shop, and have the resident tech check it for Continuity. Should only be a few bucks.

The Video Cable connections, and condition; MUST be checked before going on. You MUST rule out the Video Cable as the problem, before proceeding.

Video Cable checks OK?
On to the screen Inverter IF USED.

To test a screen Inverter requires a Sensitive multimeter.
Read fairly expensive,

http://www.fonerbooks.com/test.htm

Due to this, and the ease of accessing to replace, plus the usually low cost; the screen Inverter is just replaced.
One example,

http://battery-adapter.com/product_info.php/products_id/3773/vAspire+5535+Series

Video Cable connections checked for tightness, Video Cable condition checked, screen Inverter replaced, and problem still exists; problem is the LCD screen.

If NO screen Inverter is used, problem is LCD screen.

This is a link to THE Service Manual, (Free),

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

Go to the 'paragraph' that starts with Aspire 1200. (1200 in Blue)

Scroll across, and click on the blue -> 5535

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (5535) it may take up to 30 seconds, before the first page comes up.

There is also a way to save a copy to the computer you are using now. This way you can copy it off to a CD disk, and have it for safekeeping.

You can also delete it from the computer you downloaded it on, and save harddrive space. (AFTER checking to make sure your copy is good)
If you do not know how, and wish to; post back in a Comment.

The page numbers of the Adobe Reader, and the page numbers of the Service Manual; do NOT match.
When I refer to a page number it is for the Adobe Reader.

The Adobe Reader page number box is at the Top. It is to the Right of the Down Arrow.
You can use the Down Arrow to go page by page, to the page you want; or you can do this if you know the page you want,

1) Put your mouse cursor in the Adobe Reader page number box, at Top. Left-click once.

Screen


Suggests a problem with the Video Cable, screen Inverter, or LCD screen.

However the diagnosis starts with the graphics chipset. It has to be ruled out as the problem before going on. Otherwise you would be foolishly replacing parts, (Video Cable, screen Inverter, LCD screen), when it would do no good.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the left side of the laptop.

This is an example of a VGA Cable, and VGA connector (port),

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

Scroll down a little for the VGA Cable example.

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

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings the display should show on the external VGA monitor.
If not;

There are at least 3 display options;
A) Internal monitor of laptop ONLY
B) Internal monitor of laptop AND external VGA monitor
C) External VGA monitor ONLY

Press, and hold the Fn key down, and at the same time tap once on the F5 key. (The F5 key is the Display Toggle-Over key)
Still no?
Hold the Fn key down again, and tap once more on the F5 key.

Display is good on external VGA monitor?
Then problem is Video Cable, or inside the Display Assembly.
(screen Inverter or LCD screen)

Display is bad on the external VGA monitor, means there is a problem with the graphics chipset.
Most of the time, it is the MOUNTING of the graphics chipset TO motherboard, and not a faulty graphics chipset.

Video Cable:
The Video Cable connects to the motherboard, in an area under the Middle Cover.
(Middle Cover. Acer for Switch Cover. The plastic strip under the LCD screen, and above the Keyboard. Has the Power On button, LED indicator lights, and speakers)

It then runs under the left Hinge, and up into the Display Assembly.
From there a small cable comes off of it, and connects to the screen Inverter. The main part of the Video Cable, then connects to the back of the LCD screen.

So we have - Motherboard connection, screen Inverter connection, and LCD screen connection.

Due to the normal opening, and closing of the laptop; one or all of those connections could be loose.
The Video Cable could be pinched, and pulled on.

It can also cause damage to the Video Cable.
Example of Video Cable,

http://www.ebay.co.uk/itm/Acer-Extensa-5630-5630EZ-LCD-Screen-cable-50-4Z410-002-/200877167645?pt=UK_Computing_Other_Computing_Networking&hash=item2ec536541d

The large white connector at the Bottom, with black insulation around it; plugs into the motherboard.
The small cable with the smaller white plug connector, connects to the screen Inverter.

The main part of the Video Cable goes up, and ends in a large white plug connector. The smaller cable that goes on up from it, plugs into the webcam.

Start by checking the motherboard side connection of the Video Cable.
1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Open the laptop.
Remove the Middle Cover.
The Middle Cover pops off. HOWEVER be aware that there are cable STILL attached.

Come to the right of the Power On's rectangular button. See the parting line of the Middle Cover to Bottom Cover?
I use a thick guitar pick to insert in that parting line, and ease the Middle Cover up a little.

You can also use a Spudger Tool. I do NOT recommend using a metal tool, such as a metal flat tipped screwdriver.
You can mar the plastic parts very easily, and also can cause damage.

IF, this is your only recourse, make SURE the tip of the screwdriver does NOT go in more than 1/8th Inch. That is a tiny bit more than 3mm.

Ease the Middle Cover up, then use your fingertips, and go along the edges of the Middle Cover. You want to pop the Middle Cover off, then roll it over on the Keyboard; with the cables still attached.

The Video Cable motherboard connector, is to the left of the left Speaker, and below the left Hinge.
Visual inspection alone will NOT do. You have to physically try to plug the Video Cable connector in.

Now ease the Battery back in, and reconnect the AC adapter. Plug AC adapter back into power. Turn the laptop on. Fix the problem?
No? Go on.

Remove ALL power again.
This time you are going to check the screen Inverter connection, and LCD screen connection.

The plastic frame in front of the LCD screen is the Display Bezel.
Acer calls it the LCD Bezel.
There are 4 Screw Covers to remove. One in each corner.
Top Left, Top Right, Bottom left, and Bottom Right.

These are made of synthetic rubber, or plastic. They have a type of rubber cement on them, that holds them on.
I take a computer pick, and remove them. You may find a similar tool if you do not have a computer pick.

Start at the bottom edge where the Screw Cover, meets the Display Bezel. Lift up.
If you use care when removing you may be able to reuse the Screw Covers. Don't stick anymore? Apply a tiny dab of rubber cement with a toothpick.
I L-I-G-H-T-L-Y stick them to the Display Bezel for safekeeping.

(They like to stick to the computer pick, your fingers, and it seems sometimes passing satellites)

Remove the 4 Philips head screws. (No.1 Philips screwdriver, or comparable Jeweler's screwdriver)
The Display Bezel has TABS that go around the perimeter, of the inside edges.
These snap into matching Latches on the Display Cover.

The Display Bezel is flexible. Made of space-age plastic.
To remove use your fingertips on the inside edge at the bottom. Flex the middle of the bottom up a little.
When it is high enough, slide s fingertip underneath, and go along the Display Bezel at the bottom. Go towards the Right, or Left.

The Tabs/Latches should start releasing. Snap, snap, snap. Almost sounds like you are breaking it.
Bottom popped loose go up the Left side, or Right side. Pop those Tabs/Latches loose.

Once the Display Bezel has popped loose pretty far, it should come off. I state SHOULD. I have has Display Bezels where I had to fight it all the way off. Every Tab/Latch had to be released.

See the small circuit board at the bottom? That is the screen Inverter. You can physically check the connection, just to see if it was loose.
While you are here though, you need to check LCD screen connection. After that, then make sure the screen Inverter connection is tight.

Reason is you are going to partially remove the LCD screen, to check it's connection; and this could disconnect the screen Inverter connection.
(Remember; all connections have to be Physically checked. If the screen Inverter connection was popped partially loose, when checking the LCD screen connection, you may not see it.
Check screen Inverter connection, AFTER checking LCD screen connection )

LCD screen connection is tight, after physically checking?
Screen Inverter connection is tight?
Lay the LCD screen assembly back in the Display Cover, and Display Cover is tilted back a little bit.
(Don't want LCD screen to fall forward)

All power reinstalled, turn the laptop on again, and see if these connections were the problem.
I have run into this many times, and so have users who have posted on here, through the years.

Still no?
You MUST rule out the Video Cable as the problem before going on.
Means the Video Cable has to be removed, and checked for continuity. Nothing fancy here. You just want to make sure electricity, is passing through every wire in the Video Cable.
Test is performed with a multimeter set to OHM's (1K), and every wire is checked.
No access to a multimeter? Then suggest taking the Video Cable down to the nearest small computer shop, and have them check it for continuity. Should only be a couple of bucks.

Qosimo e15 av101 back light is dim how do I fix it


swaffordrand,

An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL or a series of LED lights, (For present technology)

The Toshiba Qosmio E15-AV101 uses a CCFL.
Cold Cathode Fluorescent Lamp.

Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
(Usually 2mm Wide, by close to the height of the LCD screen, Long )

A screen Inverter is used to convert the power (Electricity) of the laptop, for the Backlight, and LCD screen.

90 PERCENT OF THE TIME the fault is the screen Inverter.

http://www.pelltechnology.com/Toshiba/Laptop/Toshiba-Portables-Qosmio-E15-Series/AV101/Toshiba-Qosmio-E15-AV101-Backlight-Power-Inverter.html

The front thin plastic frame in front of the LCD screen, is the Display Bezel.
Resembles a picture frame in it's design.

Toshiba's name is Display Mask.

The screen Inverter is located behind the Display Mask, and mounted at an area below the LCD screen.

A) Remove ALL power. Remove the AC adapter (Charger) and Battery.

B) It would be best to buy, and wear an ESD wrist strap. Average cost is around $3 to $6. (Electro Static Discharge}
Connect it's alligator clip to a good ground source.

One example,

http://www.radioshack.com/product/index.jsp?productId=2103245

Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer. The ESD wrist strap prevents that.

It is arguable that you are just replacing a screen Inverter, and the above is 'over-kill'.
I would rather spend $6, and not have to worry that I could accidentally make my laptop an expensive paperweight, or doorstop.

Use a multi-compartment container for the various screws you will remove. SOME screws look VERY similar to other screws.

DO NOT mix them up.

C) Open the laptop, lay the Display Assembly all the way back. (Down)
Pull up on the right Hinge Cover, and remove it. Do the same for the left Hinge Cover.

To the immediate right of the right Hinge Cover, and immediate left of the left Hinge Cover, are two Philips head screws to remove.
These screw heads are covered by a piece of masking tape.

The tape is carefully removed, (May be able to use it again), and the two screws removed.

The Display Mask is very thin, therefore quite flexible.
The mask has plastic tabs that protrude from the outside edges.
There are matching tabs on the Display Cover.

(Display Cover: Plastic top cover of the laptop. Covers the LCD screen)

The Display Mask tabs snap into the Display Cover.

Go to either the Left side, or Right side of the Display Mask.
Go to the inside middle edge.
Halfway between the top and bottom of the Display Mask, and to the inside edge against the LCD screen.

Use a soft cloth laid on the LCD screen to protect it, and use a finger to gently start lifting on the middle/inside edge of the Display Mask.
(Cloth is to protect LCD screen from your fingernail)

With the Display Mask lifted in the middle, the width of a fingertip, ease another finger beside it. Start moving away from the first finger, and lifting up on the Display Mask.

The tabs of the Display Mask will start 'popping' out of the Display Cover.
Go around to the top of the Display Mask, and head towards the opposite side.

Once the Display Mask is halfway popped loose, the rest of the mask should come free.
Note that you have to slide the mask over to the Left, to clear the Latch, when removing the mask.

You will now see the screen Inverter,mounted to an area at the bottom of the LCD screen.

Unplug the cables from the Left, and Right side of the screen Inverter.
Note that the connectors on the cables are different, and can't be mixed up, as to where they plug in.

Remove the single Philips head screw from the bottom/middle of the screen Inverter.

Test the screen Inverter before removing;
This requires a sensitive (Read fairly expensive) multimeter,

http://www.fonerbooks.com/test.htm

Due to;
A) Low Cost,
B) Ease of access,
C) No tool available to test,
D) 90 percent of the time the fault is the Inverter,
the screen Inverter is usually replaced by the consumer.

Backlight:

If the screen Inverter proves to Not be the problem;

http://www.pelltechnology.com/Toshiba/Laptop/Toshiba-Portables-Qosmio-E15-Series/AV101/Toshiba-Qosmio-E15-AV101-CCFL-Backlight-Bulb-for-LCD.html

Replacing is a procedure that is fairly intensive, even for an experienced tech.

Why?
The LCD screen (Toshiba = LCD Module) is composed of many layers.
These layers are set in a specific pattern by the factory.

The layers are held in place by a Screen Frame. A thin metal frame that resembles a picture frame. (Toshiba = P-Chassis )

Part of the screen frame is removed. The screen frame Bezel.
(P-Chassis Bezel)

[ The P-Chassis, or screen frame, is composed of TWO parts. The lower main half which is the P-Chassis, and a thin upper half which is the screen frame Bezel, or P-Chassis Bezel.

This will all make more sense when you view it in the Service Manual, on Page 281 ]

Anti-Static computer gloves are usually worn to prevent soiling the LCD Panel, (LCD screen)
(Soiling = Oil from your fingers, dirt, and also helps prevent scratching the LCD screen )

There is a panel, or Board, that goes across the top. Three screws are removed. Then open the bent portion of the TCP of the board, and remove the Backlight.

The Display Assembly needs to be removed from the laptop, in order to perform replacing the Backlight lamp. (Bulb)

What do you have to do to change the screen on my toshiba laptop


First You Need To Remove The 6 Screw Covers..(plastic Sticker Covers)... 2 are located at the bottom of the screen (on each side of the TOSHIBA logo)... The Other 4 are on the Sides of the Screen..(2 on each side)...

Then Unscrew the 6 Screws

THen You Need To Pry The Front plastic Bezel From The Back Panel...

Use a guitar pick or thin plastic card to pull bezel away... start from the top middle, insert plastic tool in between the black front bezel and the silver back panel, Pry outward at a 45% angle until you unsnap it...
Slide your Plastic tool around the outer edge unsnapping all the snaps, then Pull the front bezel away/set aside....

THen you will need to unscrew the Side Rail Screws and the 2 screws on the top of the side rail posts..THese Hold the Screen To The Inside....

Then Tip The Screen Forward From The Top -- Pull It Outward and Lie It Down Flat On THe Keyboard....You Now Need To Unplug The Display Ribbon Cable....
There's a Piece Of Tape that secures the Display Ribbon Cable Port To THe Screen... Pull The Tape Downward and use the rest to pull the cable away from the screen... Unplug the LCD Bulb cable from the power inverter now....(the Pink and White/Or Red and White)

Your Screen Is Now Detached and Fully Removed From The Laptop...

The screen on my laptop computer has become dark. If I shine a light on the screen I can barely see the display and if I connect an external monitor to the computer I get a display on the remote monitor....


The LCD display connection is loose. Try reconnecting this and the display will be fine. The connection should be at the top of the base right above the keyboard under the plastics.

Lines on laptop


If the lines are like static black stains, then that is a faulty LCD panel, with a liquid crystal leak.

If the lines are colored , and come on when you turn on the laptop, that is a problem with LCD ribbon cable or connector, or a broken connector on motherboard or LCD display.

Either the LCD display, or the ribbon connector must be replaced.
To do that you need to take apart the laptop, the repair should be done by a technician.

sounds like you have the wrong monitor drivers installed,  download updated monitor drivers from the manufacturer's website,

also check your display settings,  as something is really wrong there.
