Could you post a picture of your problem? The issue is probably that the screws holding the monitor mount to the rotating piece have stripped and come out, and the small piece that is meant to stay screwed in is spinning freely. This can spread that area out and pop open the monitor casing.

You can pop off the small rubber "feet" that go around the monitor to gain access to the screws. You may be able to position the monitor in the correct angle and screw it back in with a precision screw driver. If this was the problem then this is most likely a temporary fix. If the screw has come out once, then the groove is stripped and it will happen again. You'll either need a new screw or most likely a new hinge in the future.

Regardless, try posting a picture and I'll be able to help you more.

Display problem

Sounds like the LCD has some damaged crystals in it. Try connecting the netbook to an external pc monitor using a VGA cable. Hold the Fn key and hit the F8 or F7 key until the display shows on the external monitor. This will determine if it's a driver/settings or display issue. If the display is fine on the external monitor, the LCD display on the netbook is the problem. Good luck!

How to maximize my computer screen and keep it that way

Maximum is for a window. For example when you open a program or a internet browser, then in the upper right hand corner just to the left of the X will be the minimize or maximize toggle that you click.

If you are talking about your screen resolution which makes icons bigger or smaller then that is in the Display in the Control Panel. Click Start/Control Panel or Start/Settings/Control Panel and look for Display or Appearance and Personalization. Open it and adjust the screen resolution. The higher the resolution, the smaller the icons.

Right Click on an open area on the desktop and click Properties. When the display properties window opens click the Appearance Tab and look down near the bottom left and change the font size to Normal.

You can also get to the Display by clicking Start/Control Panel and look for Display or Appearance and Personalization. Once the display opens click the Appearance tab then look at the bottom left you will see the Font Size drop down window. Change it to Normal.

Led screen replacement


HP Support > Pavilion DV6-3129nr Notebook PC > Manuals > Service Manual,

(I suggest click on the X at the upper right corner, of the HP -Your input is valuable, small window)

Scroll down, click on the 3rd file down -
HP Pavilion dv6 Entertainment PC - Maintenance and Service Guide

Disregard the following if you are aware;

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

3) At the top of the PDF file (Header) is the page number box.
It is to the right of the Down Arrow.

You can use the Down Arrow to arrive page by page, to the page you want,
If you know the page number you can do this;
A) Left-click once in the page number box.
(What is in the page number box will now be highlighted in Blue)

B) Type the page number
C) Press the Enter key.

You can also use the Bookmarks menu to the left.

4) In the header at the top of the PDF file, is also the Zoom In tool ( + ),
and the Zoom Out tool. ( - )
Zoom In increases the view size.
Zoom Out decreases the view size.

In the Bookmarks menu to the left click on the + sign, next to -
Removal and replacement procedures
Now click on the + sign next to -
Component replacement procedures.

Or go to Page 77 - Brightview display assembly

1) Work on a table. Suggest lay a soft static free cloth on the table, to work on. Helps protect the table, and the laptop from scratching.

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

3) Remove the following in order;
A) Hard Drive Cover - Page 54
B) Hard Drive - Page 55
C) WLAN Module
D) Optical Drive (DVD Drive)
E) Keyboard
F) Top Cover (Palm Rest Cover)

Removing the WLAN Module. (Wireless Local Area Network Module)
First step is removing the two small cables attached to the module.
These cables go through the body of the laptop, and up into the Display Assembly.

In the proceeding steps you'll see the WLAN Module cables thread through the bottom of the laptop; through a space next to the motherboard, go along the Top of the motherboard, and then go up under the Right Hinge, and into the Display Assembly.

The WLAN Module cables go with the Display Assembly, when it is removed.
You have to remove the WLAN Module, in order to start threading these cables through. (After disconnecting them from the module)

Make a note, and if you wish a crude drawing, as to where those two cables attach on the module, BEFORE removing them.

There are TWO terminals on the WLAN Module.
There is a White wire, and a Black wire. (Cables)

The Keyboard is removed so the Top Cover can be removed.
The Top Cover is removed,

1) To finish threading the WLAN Module cables out,
2) To access the Display Panel Cable. (Video Cable),
3) To access the 3 Philips head screws that hold the Hinges, (And Display Assembly) to the body of the laptop.

(One on the Left Hinge, Two on the Right Hinge)

The Keyboard Cable stays attached to the Keyboard. It removed from a connector on the motherboard. The Keyboard Cable, and it's respective motherboard connector, are special.

The Keyboard Cable is a FFC. Flat Flex Cable,

(Click on the second photo down. 35 conductor flat flex cable)

The flat flexible cable has NO connector on the end. It just has metal contact strips.
This flat cable slides into the motherboard connector, and is locked into position.

The motherboard connector is a type of ZIF connector.
Zero Insertion Force.

It is a small rectangular plastic connector, composed of TWO parts.
The bottom piece is larger. It is the BODY.
The Body has the contact pins.

The top piece is smaller. Rectangular shaped also, but much narrower in Thickness.
This is the Locking Bar.

The Locking Bar is wedge shaped. Designed so that when closed against the Body, it wedges, or locks, the Keyboard Cable in place.

The Locking Bar ONLY moves just a little bit. About 2mm, or slightly larger than 1/16th of an Inch.

IF the Locking Bar is moved TOO far, it will break.
This means motherboard replacement.

The procedure is to use your two index fingernails, and ease the connector open. (Ease the Locking Bar away from the Body)

Some 'techs' use a flat tip Jewelers screwdriver. I Do Not recommend it for your first time. One slip may = broken Locking Bar, or damage to the motherboard.
It's your call.

For this type of ZIF connector, the Locking Bar is GENTLY lifted UP, on the Back side. ( Display Assembly side )

After the WLAN Module cables have been threaded through, and are hanging loose, and after the Display Panel Cable has been disconnected, (Only plugs in one way. No worries), the Hinge screws are removed.

Remove one of the two Philips head screws from the Right Hinge.
Hold the Display Assembly.
Remove the other screw from the right Hinge.

Now remove the screw from the left Hinge.
Gently lift up on the Display Assembly, and ensure that nothing is still attached, before removing it.

Display Assembly removed:

At the bottom two corners are screws. They are covered by a Screw Cover. A rubbery cover that has a type of rubber cement on it.
Gently pick the covers off. I use a computer pick. You may wish to use a device that is similar.

If you are careful, you can reuse these covers. Lay them upside down on a flat surface. (Yes. They like to stick to the tool, and your fingers)

Two Screw Covers removed, remove the screws.

(Use a multi-compartment container, for the various screws you will remove.
Label each compartment for the area the screw/s come out of.

SOME screws look VERY similar to other screws.
Advise do NOT mix them up )

The Hinge Covers are U-shaped. Pop them up, and off.
The Display Bezel is the thin plastic frame in front of the LCD screen.
Resembles a picture frame.

It is pretty flexible, and pretty tough. (Space-age plastic)
Removal method is to use your fingertips, and flex the inside edges, of the Right side, and Left side.

Flex the inside edge up a little on both sides.
The Display Bezel snaps into the Display Enclosure.
(Laptop closed looking at top. That plastic cover is the Display Enclosure)

There are tabs on the Outside edges of the Display Bezel, and matching tabs on the Inside edges of the Display Enclosure.
When the Display Bezel is removed, there is a snapping sound for the release of the tabs.

If gently flexing up on the inside edges, Left and Right side, of the Display Bezel is not working;

Flex the middle of the inside edge, UP, of the Left side of the bezel.
Carefully work a finger towards the Top. The tabs should start releasing.
Now do the same for the Right side of the bezel.

Go towards the bottom now.
After the Display Bezel is released, you may have to slide it a little bit, one way or the other, to remove it. (Latch)

Display Bezel fully removed, there are 6 Philips head screws to remove from the corners of the Screen Frame, of the Display Assembly.
These screws hold the Display Assembly TO the Display Enclosure.

ONE screw at the Top two corners, TWO screws at the Bottom, for each corner.

EASE the Display Assembly up. DO NOT go too far. You have to disconnect the Display LED Cable, from the Display Panel Cable.
Now remove the Display Assembly.

Remove the Display Hinges from the Screen Frame.

(The metal frame that surrounds the LCD assembly, is the Screen Frame.
Note* The LCD screen is an assembly. It is composed of layers, and these layers are aligned by the factory. Then the Screen Frame is put around the layers )

There are 6 screws to remove in order to remove the Display Hinges.
3 on each side, (3 for each Hinge)

There are also screws which can be removed, and this will take the Screen Frame apart.
Suggest ONLY remove the Hinge, to Screen Frame screws.

Carefully remove the sticky tape, (REAL sticky), from the Display Panel Cable, where it attaches to the LCD screen (Assembly)
Now you can carefully disconnect the Display Panel Cable.

Reverse these steps to replace the LCD screen.
(The LED Backlight is a series of LED lights. They are an integral part of the LCD screen assembly)

Please dispose of the LCD screen properly.

Observe the routing of the various cables through their respective channels, and latches. They MUST be reinstalled in the SAME routing.
(WLAN Module cables, Display Panel Cable, Webcam cable, Microphone Cable, etc)

If you do not own an ESD wrist strap, I would advise buying one, and wearing it. (Also make sure it's alligator clip is connected to a good ground source)
The average cost is around $3 to $6.
Just one example,

Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components, of a computer.
Wear an ESD wrist strap, with it connected to a good ground source, and your laptop is SAFE.

It isn't the Display Assembly side that concerns me so much, as the motherboard side after the Top Cover is removed.

Two disassembly pictorial guides that may help. It's for an HP pavilion DV6 series of Notebook PC, but differs slightly from your particular model,

[ Top Cover for yours is all one piece. No separate Switch Cover.
No screw covers, and screws next to the base of the Hinges. (At the Body of the laptop)

There are 3 screws that hold each Hinge to the Screen Frame, not 2 as in the article. { LCD removal)

Shows good detail for unlocking the Locking Bar.
Guitar pick is a method I use sometimes. May be best for you ]

1) Removing the Display Assembly;

2) Replacing the LCD screen;

It seems that you need to use the latest driver for the graphic card.

You can do that through visiting the manufacture's website, choose your laptop model, OS, look for video (vga) driver, and download it.

One way to adjust/set the default size (to get a larger font size) is through your Control Panel - Display - Settings window, where you can select a larger font.
If you are using a browser (e.g. Internet Explorer), there is way to increase (or decrease) the font size (displayed on the screen) using the "magnification" option at the bottom right corner of the screen. Simply click on the "magnifying glass" and increase/decrease the value, e.g. to 150% .
