Today I will be removing and replacing the LCD screen in an IBM ThinkPad T43p laptop. You can use same set of instructions for ThinkPad T43 and some other IBM (now Lenovo) laptops.

Failure description: the laptop starts with a reddish screen (white color appear to be pink). After a minute or two the backlight goes completely off but you still can see a very faint image on the screen if you look very closely. When you restart the laptop, the screen lights up again but a minute later the light goes off.

Solution: the laptop has a failing backlight lamp which is a part of the LCD screen. The whole screen has to be replaced.

You can try replacing just the backlight lamp without replacing the screen, but it’s not easy and should be done only by an experienced technician.

Let’s disassemble the display panel and remove the LCD screen.

STEP 1.

Carefully remove four screw seals from the bottom part of the display bezel.

You can remove them with a sharp object.

Remove all four screws found under the seals.

STEP 2.

Remove three screws (found under seals) from the left side of the display panel.

STEP 3.

Remove four screws (found under seals) from the right side of the display panel.

STEP 4.

The display bezel is glued to the LCD screen with sticky tape. You can separate the bezel using a guitar pick (as I do) or another piece of plastic.
Insert the guitar pick between the display bezel and screen and carefully move it along the side until the bezel is separated.

STEP 5.

Continue removing the display bezel with your fingers.

STEP 6.

The screen inverter is mounted under the bezel and can be replaced without removing the bezel completely. I’ll remove the display bezel because I have to replace the LCD screen.

STEP 7.

The display bezel has been removed.

STEP 8.

In order to confirm the backlight lamp failure I did the following experiment.
I unpluged the LCD screen from the right side of the inveter board and pluged in an known good backlight lamp. After that I turned on the laptop and tested it with my backlight lamp for about 10 minutes. My backlight lamp didn’t turn off and worked fine all time. That means the backlight lamp inside the screen is bad.

If your laptop doesn’t work with a known good backlight lamp, most likely you have a problem with the inverter board.

STEP 9.

Unplug the inverter board from the video cable.
Remove the inverter board.

Do you need a new inverter board? Find a new inverter here.

STEP 10.

Carefully separate the LCD screen from the display cover. Do not forget to release the cable with night lamp. Simply pull the cable from the display cover.

STEP 11.

Now you can access the back side of the LCD screen and unplug the screen cable.

Remove sticky tape securing the connection and pull the cable connector from the LCD screen.

STEP 12.

Remove the LCD screen from the laptop.

The LCD screen has been removed.

Be careful with this piece of plastic. Try not to remove it from the display because it will take some time to figure out how to connect it back together.
I believe this piece of plastic is designed to prevent the screen cable from breaking when you close the display.

STEP 13.

Remove two screws securing the display mounting brackets.
Remove the bracket and move it to a new LCD screen.
Do the same with the bracket on the other side of the screen.

You can find a new LCD screen using two different part numbers from the back side of the defective screen:
1. The model number of the LCD screen. In my laptop it is N150U3-L01
2. FRU part number. In my laptop it is 92P6753.

In this guide I’ll be removing the LCD screen and inverter board from a Dell Inspiron 9400 laptop. You can use same set of instructions for a Dell Inspiron E1705 and probably some other Dell laptops. If my guide works for you, please mention the laptop model in the comments below.

Need a new LCD screen for your Dell Inspiron 9400 laptop? Find it here for less than $100.

Like in most other laptops, in this model the LCD screen is mounted between the display cover and front bezel. You’ll find eight screw seals on the front bezel. Six rubber seals (red circles) and two plastic seals (green circles).

Remove rubber seals using a sharp object. Glue these seals somewhere on the front bezel so they don’t get lost.

Remove two plastic seals using the same tool. Also, glue them somewhere on the front bezel.

Remove all eight screws found under the seals.

When all screws are removed you can start separating the front bezel from the display cover.  Use your fingers and a piece of soft plastic. In this guide I’m using a guitar pick.

Continue separating the front bezel.

The front bezel has been removed.

There are screws securing the LCD screen to the hinge bracket. You’ll find four screws on each side.

Remove four screw on one side of the display panel.

And after that remove four screws on the other side of the panel.

Now you can separate the LCD screen assembly from the cover.

Be careful, there is a video cable connecting the LCD screen and inverter board to the motherboard.
Place the LCD screen on the palm rest so you can access the video cable and unplug it from the LCD screen and inverter.

Press on latches on both sides of the video cable connector and pull it from the LCD screen.

Unplug the other end of the video cable from the inverter board.

Now you can remove the LCD screen and inverter board. As you see, the inverter board is attached to the LCD screen frame. It’s very common setup for Dell laptops.

The inverter board is mounted inside the metal casing which is a part of the LCD screen frame.
Remove one screw securing the inverter board and turn the LCD screen upside down.

Unplug the backlight cable from the inverter board.

Carefully remove the inverter board from the metal casing and replace it with a new one if needed. You can buy a new inverter board here for about $15-20.
When you buy a new LCD screen for your Dell laptop, it might come with the inverter board already attached to it. It’s very common. If that’s the case, you don’t have to remove the old inverter.

Before you start do not forget to turn off the laptop, unplug the AC power adapter and remove the battery.

STEP 1.

On the screen bezel you’ll find six screw seals. Four rubber seals and two plastic seals.

You can remove these seals with a sharp object.
Remove all six screws found under the seals.

STEP 2.

Start separating the screen bezel from the display cover with your fingers. You can use a piece of soft plastic to separate the bezel.

Continue separating the screen bezel on the top of the display and after that move to the lower part.

Finally, remove the screen bezel.

STEP 3.

Remove four screws securing the LCD screen to the left mounting bracket.

STEP 4.

Remove four screws securing the LCD screen to the right mounting bracket.

STEP 5.

Remove two screws securing the web camera.

STEP 6.

Separate the LCD screen assembly from the display cover. As you see, the web camera is still attached to the screen assembly.

STEP 7.

Plase the LCD screen assembly upside down on the palm rest.
The green ribbon cable is the video cable and it has two connectors. One of the is connected to the LCD screen and another one to the inverter board.

Carefully push on two latches on both sides of the LCD connector, release the cable and disconnect it from the LCD screen.

Pull the second connector up and disconnect it from the inverter board.

STEP 8.

Remove the screen assembly (LCD screen and inverter board).

The inverter board is attached to the bottom part of the LCD screen. The inverter board can be replaced separately.

The best way to find a new replacement screen is searching by the LCD screen model number or Dell part number. Both numbers can be found on one sticker with a barcode.

You can find a cheap replacment LCD screen for Dell Vostor 1500 and other Dell laptops here.

In this guide I explain how to remove and replace a damaged LCD screen in a HP Pavilion dv2000 notebook. This guide should work for all models in Pavilion dv2000 line.

By the way, this HP Pavilion dv2000 is like a small copy of HP Pavilion dv6000 notebook and all disassembly steps will be very similar.

Before you start, please turn off the laptop, unplug the power adapter and remove the battery.

STEP 1.

The LCD screen is mounted between the display cover and bezel. The screen bezel is secured to the display cover by six screws hidden under six screw seals. I circled these screw seals.

Remove all seals with a sharp object and after that remove all screws found under the seals.

STEP 2.

Start separating the screen bezel from the display cover on one of the top corners.

Continue separating the screen bezel.

Remove the screen bezel.

STEP 3.

The inverter board works as a power supply for the backlight lamp hidden inside the LCD screen. In most notebooks the inverter board is mounted below the LCD screen. In my guide I will not be removing the inverter board and because of that I will unplug only one cable from the right side.

STEP 4.

Remove four screws securing the display hinges to the cover.

STEP 5.

Carefully separate the display assembly from the cover and place the LCD face down on the keyboard.

Now you can access the LCD cable (video cable) connector. The LCD cable connects the screen to the the motherboard.

STEP 6.

Unplug the LCD cable from the screen.

STEP 7.

Remove the LCD screen assembly from the notebook. As you can see, the screen still has two mounting brackets attached to the left and right sides.

STEP 8.

In order to remove the mounting bracket, simply remove three screws. Transfer the bracket to the new screen.

This guide explains how to remove a broken LCD screen from a Lenovo X60s laptop and replace it with a new LCD screen. The display disassembly procedure will work for some other IBM ThinkPad and Lenovo laptops. If this guide works for your laptop, please mention the model in the comments.

Before you start, please turn off the laptop, unplug the AC adapter and remove the battery.

STEP 1.

There are three screw seals on the bottom of the display bezel. These seals hide three screws securing the display bezel to the display cover.

You’ll have to remove all three screw seals with a sharp object and after that remove three screws.

STEP 2.

There are three screw seals on each side of the display assembly. Remove TWO seals I marked from each side of the display. Remove screws found under those seals.

STEP 3.

Start separating the display bezel from the cover as it shown on the picture below.

Continue separating the bezel.

The inverter board is located below the LCD screen. In order to access and remove the screen inverter it’s not necessary to remove the bezel completely.

Finally, the display bezel has been removed.

STEP 4.

Disconnect the screen backlight cable from the inverter board.

STEP 5.

Now you can separate the LCD screen from the display cover and access the video cable connector on the back of the screen.

STEP 6.

The video cable is plugged into the connector on the LCD controller board. There is clear tape securing the connection. Carefully remove clear tape.

STEP 7.

Unplug the video cable from the LCD screen.

STEP 8.

Now you can remove the broken LCD screen and replace it with a new one. Search for a replacement LCD screen using the FRU part number from the back of the original screen. You can find a cheap replacement screen here.

In this guide I will remove the LCD screen and FL inverter board from an Acer Aspire 3620. The guide will work for other Acer Aspire models. If it works for your, please mention the model number in the comments below.

You’ll find my first disassembly guide for the same Acer Aspire 3620 in the previous post where I explained how to remove the motherboard and clean the cooling module.

Let’s start taking it apart.

Step 1.

You’ll find four rubber plugs in four corners of the LCD screen bezel. Remove these plugs with a sharp object and glue them somewhere on the bezel so they don’t get lost. Remove four screws hidden under the rubber plugs.

Step 2.

Start separating the screen bezel with your fingers. I found it’s easier to separate the bezel if you start from the top.

Continue separating the bezel. Be careful with the display latch, it has to stay attached to the screen cover.

Finally, remove the LCD screen bezel.

Step 3.

You’ll find the screen inverter board also known as FL inverter mounted below the LCD screen. Remove two screws securing the inverter board.

Step 4.

In order to remove the inverter board, you’ll have to unplug two cables.

The black cable on the left side is connected to the motherboard. It supplyis power to the inverter board from the motherboard.
The cable one the righ side is connected to the backlight lamp inside the LCD screen.

Now you can replace the inverter board with a new one if needed.
I’m not going to remove the LCD screen because I’m taking it apart just for this guide.

Step 5.

Remove two screws securing the LCD screen brackets to the hinges.

Now you can separate the LCD screen assembly from the cover and access the back side of the screen.

In order to remove the LCD screen assembly you’ll have to unplug the video cable first.

After the video cable is unplugged, you can remove the  LCD screen assembly (screen and mounting brackets).

If you are replacing the screen with a new one, you’ll have to transfer mounting brackets to the new screen. You can find a new screen for your Acer Asprie 3620 (and any other Acer laptop) here.

I have seen a few Toshiba Satellite M305 and M305D laptops with exactly the same display problem. When you move the display panel, the image on the screen flickers, some random horizontal lines appear in random places or the image disappears at all. As soon as you stop moving the display, the image ether turns back to normal or the display continue to remain black.

I did some research and found that this problem could be related to the display cable made by CMI.

How can you tell if the display cable was made by CMI? You’ll have to open up the display panel and take a look at the letters and numbers below the barcode on the cable. If first three letters are CMI, the cable was made by CMI.

The following models could have a faulty display cable: Toshiba Satellite M300, M305, M305D and Toshiba Satellite Pro M300.

If you experience a similar problem with your Satellite M305 or M305D laptop, try replacing the display cable first. If the problem still exists, even after replacing the cable, apparently it’s related to the LCD screen.

If the laptop is still under warranty do not open the case or you will lose the warranty. Take your laptop to the authorized repair center.

In this guide I’ll be removing and replacing the LCD screen and removing the inverter board from a HP Pavilion dv6000 laptop.

As you see on the picture above I’m fixing a HP Pavilion dv6000 series laptop with a bad LCD screen. The lower part of the screen displays garbled image and the upper part works just fine. An external monitor displays image properly. So it’s bad screen and it has to be replaced.

By the way, you’ll find another disassembly guide for the same laptop in my previous post.

STEP 1.

There are six rubber screw covers on the LCD screen bezel. You’ll have to remove all covers.

You can remove covers with a sharp object.

STEP 2.

Remove six screws found under the rubber covers.

STEP 3.

Insert fingers between the screen bezel and display cover and start separating them.

Continue removing the bezel. Be careful, the bezel made of fragile plastic.

The screen bezel has been removed.

STEP 4.

Now you can get an access to the screen inverter which is mounted below the screen.

Remove one screw securing the inverter board. Disconnect cables on both sides of the inverter board.

The inverter board has been removed.

STEP 5.

This guide will help you replace the screen inverter in a Dell Latitude D800 laptop. As in most other models, the inverter board is mounted inside the display panel and located below the LCD screen.

You will find the display panel diagram in the service manual for Dell Latitude D800.

Screen inverter failure symptoms:

1. The laptop starts normally and video works fine for a while but after some time the screen goes very dark. You still can see the desktop but it’s very faint.
2. When you turn on the laptop, the screen lights up for a moment and goes off.
3. You can light up the screen for a short period of time by pressing on the lid close switch.

You can search for a new screen inverter for Dell Latitude D800 laptops here.

By the way, when the inverter board fails, you still can use the laptop with an external monitor connected to the VGA port.

1. Turn off the laptop.
2. Connect an external monitor.
3. Start the laptop, it should detect the external monitor automatically. If the external monitor is not detected, try switching video from internal to external mode using Fn+F8 key combination.

Do you have a Toshiba Tecra M4 or Satellite R15 Tablet PC? The display is loose and wobbly? Probably it’s time to tighten the display hinge. Both Tecra M4 and Satellite R10/R15 Tablet PCs are very similar so you can use the same display disassembly instructions.

In order to access the display hinge you’ll have to remove the LCD cover. There are four screws securing the hinge, I pointed them with red arrows on the picture above. Tightening these screws will help to make your display less wobbly.
