    It seems the power up is a fake, i do get the power led but no response from the num lock or fn key combos. Tried a stick of 1 gig mem that i know is a good stick from another comp i have.

    NO luck.

    The cpu works fine i tested it in a dell my friend had.



    i even ripped th whole thing into peices to try to find a burnt or cracked chip no luck on that either.

    any other info that anyone can provide would be great thanks so far. I know its a checklist kinda thing that has to be done to find the problem and my fear is itts the main board does anyone have one for sale? cant find any on ebay.

Problem is;

1) Bad graphics chipset,
or
2) Bad Video Cable, or loose connections,
or,
3) Bad screen Inverter,
or,
4) Bad LCD screen.

A) Graphics chipset:

(Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

The chipset, or I.C. used for graphics; is the graphics chipset.
More properly known as the G.P.U.
Graphics Processing Unit,

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

Laptop OFF, monitor OFF, connect a VGA monitor; to the VGA connector on the laptop. (Port)
(Left side of laptop, if memory serves)

This is a General example of a VGA connector, (Port), and VGA cable,

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

You can use a CRT type of 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;

You have at least 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold the Fn key down, and at the SAME time tap once on the F4 key.
(The F4 key is the Display Toggle-Over key)

Still no?
Hold the Fn key down again, and tap once more on the F4 key.

Same display on external VGA monitor (Red lines), suggests problem with the graphics chipset.
Good display on external VGA monitor means;

Problem with;
1) Video Cable
2) screen Inverter
3) LCD screen

If you find it is one of the three stated above, post back in a Comment; and I'll guide you step by step, in diagnosing.

Will require partial disassembly of laptop, but not very far.
Will also require an ESD wrist strap.
Average cost is around $3 to $6.

Example,

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

Needed to keep from Static shocking, the delicate hardware components inside the laptop.

[All power removed;
Loosen Keyboard, and roll over out of the way. Do NOT disconnect Keyboard Cable.
Remove Keyboard Cover.
Remove Display Bezel.
Remove screws that hold LCD screen to Display Cover, and check Video Cable connections to back of LCD screen.

The plastic frame in front of the LCD screen, is the Display Bezel.
Laptop closed the top cover is the Display Cover.

Just basic instructions. Like I said, I will step by step you through it, if you wish ]

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

A Backlight can be a CCFL (or more than one), or a series of LED's.
(Light Emitting Diode)

The Compaq Presario CQ61 series of Notebook PC's, uses a single (1) CCFL.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses; but on a MUCH smaller scale.

Average thickness is 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital letter -> O <-

Average length is almost as long, as the LCD screen is in height.
View the last 8 photos,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

The screen Inverter converts the power (Electricity), from the laptop; for the LCD screen, and Backlight.
Backlighting that uses CCFL, uses a screen Inverter.

Backlighting that uses a series of LED's, May or May Not use a screen Inverter.
It seems when the LED technology first came out, they did.
Later designs do not seem to.

The 450sx4 screen is bright but no video


Many computer users spend long hours online every day and don\'t realize that looking at a bright laptop screen can be hard on the eyes. If you spend a lot of time in front of a laptop screen, consider reducing the brightness of the screen at the earliest opportunity. There\'s a quick and easy way to perform this task so you can save your eyes as well as your battery power.

Press and hold the "Fn" key on the laptop keyboard. This key is usually located at the top right or bottom left of the keyboard. Press the "Up Arrow" and "Down Arrow" keys, which are usually located in the lower right of the keyboard, to increase or reduce the brightness of your laptop screen. Adjust the level so that you can gaze comfortably at the screen without any glare. Disconnect the battery charger from your laptop and repeat the above procedure. On some laptops, the screen brightness varies considerably, depending on whether or not the device is charged. Hope this helps.

Fix my broken acer aspire 9805wkhi display


Horizontal lines going down the screen, generally indicate a problem with the Video Cable, or screen Inverter.

The Acer Aspire uses a screen Inverter, because the Backlight is a CCFL. (One)

Primer before I go on;
An LCD screen cannot produce light. 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.
(Light Emitting Diode)

As stated previously; the Aspire 9805wkhi Notebook PC, uses a single CCFL for a Backlight.

http://www.screentekinc.com/Acer_Aspire_9800_Series_9805WKHi--20.1-inch--1680x1050-wsxgaplus-laptop-lcd-screen.shtml

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

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

Basic example of a CCFL,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen, and Backlight.
Note* Laptops that use a series of LED's for a Backlight, do not use a screen Inverter.

Primer over.
A) An external display device, such as a VGA monitor for example; should be connected to the laptop ->First; to make sure the graphics chipset is OK.

I believe it is OK, but this is a diagnostic flowchart, and the graphics chipset HAS to be eliminated as the problem; Before going on.

Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.

The VGA port is right in the middle, on the back of the laptop. Here is an example of a VGA port,

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

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

With this laptop you can also plug a DVI connector, from a flat LCD screen monitor (Usual connector for digital flat screen), and use it instead. It's the white(?) port right next to the VGA port. (Closer to Left side, than VGA port)
Example of a DVI port, and DVI cable,

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

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

There are at least 3 display options;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external display device
3) External display device ONLY

Press the Fn key, hold it down; and tap once on the F5 key.
(The F5 key is the Display Toggle-Over key)
Still no graphics on external display device?
Hold the Fn key down again, and tap once more on the F5 key.

Good graphics on external monitor = Go on.
Bad graphics on external monitor = Problem with the mounting of the graphics chipset; to motherboard. Or bad graphics chipset. (Not very common)

B) Video Cable:
The Video Cable connects to the motherboard, up under the Keyboard. (And Top Cover's metal Static Shield) From there it routes up under the left Hinge, and up into the Display Assembly.

The main part of the Video Cable, then connects to the back of the LCD screen. There is also a separate cable coming from the Video Cable, that connects to one side of the screen Inverter.

The thin plastic 'frame' in front of the LCD screen, is the Display Bezel.
The screen Inverter is a small long circuit board; located behind the Display Bezel, and mounted down towards the bottom of the Screen Frame.
Basic example,

http://www.amazon.com/Inverter-Aspire-6930G-8920G-8930G/dp/B005GCD446

{The LCD screen is an assembly. It is composed of layers held in a specific pattern, by the Screen Frame. A thin metal 'picture frame', if you will.

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

Click on the monitor icon }

Due to just normal repeated opening, and closing of the laptop; the Video Cable can become pinched, then pulled on.
This can lead to a loose connection at the motherboard side; and/or back of LCD screen. (Also check screen Inverter connection)

Can also cause damage to the tiny wires inside the Video Cable.
(Stretched/Broken)
If there is obvious signs of damage to the sheath of the Video cable, there may be damage to the tiny wires inside.

To add; with age the insulation of the tiny wires inside the Video Cable, can deteriorate.
This can lead to exposed wires inside the sheath of the Video Cable, and lead to their touching each other.

It is best to perform a continuity check, with a multimeter set to OHM's. (1K)
Check each wire. Also have an assistant gently wiggle the Video Cable, as you check it. (Fluctuation of reading of multimeter, indicates a broken wire)
If you do not have access to a multimeter, perhaps take the cable down to the nearest small computer repair shop; and see if they will run a continuity test for you. (Few bucks)

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


Problem here is there is no Service Manual; nor guides in how to disassemble, that I have found; nor has one come into the shop.
(Made in what? 2006? Hmmm?)

Looking at the reviews of it, to see what it looks like; the laptop looks to be the type of model that the Keyboard is removed, then the Top Cover (Upper Case); THEN access to the motherboard side of the Video Cable, can be gained.

Fun stuff, huh?

ALL power is removed. Remove the AC adapter (Charger), and Battery.
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.

Basically follow what this gentleman is doing. Screw locations may not be the same for the inside area on the bottom; but will have screws that go around the perimeter of the Base Enclosure.
(Bottom Cover)

http://www.youtube.com/watch?v=6k-FnZze3c0

Also on yours, look down in the Battery Compartment for screws to remove, and when the DVD drive is removed, see if any screws are along the 'lip'. The outside edge of the laptop; where the outside edge of the DVD drive was.
(Going from bottom view towards the Top Cover, there may be screws in that 'lip')

Look along the compartment opening edges, too. (Along the lines of the one's he found )
Ram Memory compartment, etc.

The Keyboard has Tabs on the bottom edge. The edge that faces you, not LCD screen side.

http://www.amazon.com/Acer-Aspire-9805WKHI-Replacement-Keyboard/dp/B006T0V8VA

(Click on photo to enlarge)
When the Keyboard is removed, it is slightly tilted up on the LCD screen side; and then moved forward a little. (LCD screen side)
If you lift the Keyboard straight up, you may break the Keyboard tabs, and/or Top Cover.

The top of the Keyboard has Detents.
May be 3 to 4. (Maybe 5)
The Detents are small (Very) rectangular shaped, and right above the Keyboard. Once depressed with a flat tipped Jeweler's screwdriver, the Keyboard can be slightly lifted in that area. (LCD screen side)
Then go to the next one, and slightly lift the Keyboard, and so on.

The Keyboard Cable STAYS attached to the Keyboard. It has NO connector on the motherboard end. (No plug connector)
It is a Flat Flex Cable.

After all screws are removed, the Top Cover pops loose.
The Top Cover has Tabs, and the Base Enclosure (Bottom Cover), has matching Latches.

http://www.youtube.com/watch?v=3AxVE6__kEY

You have to PHYSICALLY check the motherboard connection side of the Video Cable, AND LCD screen side. Visual inspection will NOT do.

http://www.insidemylaptop.com/replace-screen-on-acer-aspire-5830tg-6782-laptop/

Look for screw covers going around the perimeter, of the Display Bezel. These are usually plastic, or synthetic rubber. I just gently pry up on one side of the cover, and then pry it up, and off.

The screw covers are attached with a type of rubber cement.
If carefully pried off, the screw cover, and it's glue may be reused.
[ Most of the time. I stick them (L-I-G-H-T-L-Y) to the Display Bezel, for safekeeping ]

Now remove the Philips head screws.
The Display Bezel is gently pried off, by flexing one side; and sliding your fingertips under it.
(On LCD screen side. I wear computer gloves. You may wish to cut a cereal box, or similar cardboard; to fit the inside edges of the Display Bezel; and protect the LCD screen from your fingernails )

Work along heading towards the Top, and around.
Once the Display Bezel has popped about halfway, or more off; the Display Bezel should come the rest of the way off all at once.

Remove the screws which hold the LCD screen to Display Cover.
Tilt the top of the LCD screen towards you; so you can access the Video Cable connection; to LCD screen.

Continuity check reveals the Video cable to be OK? Connections were tight?
Replace the screen Inverter.

Testing a screen Inverter = using a Sensitive multimeter.
Read fairly expensive,

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

Due to this; the low cost, and ease of access to replace; the screen Inverter is usually just replaced. Have to work with what you've got.

Screen Inverter replacement doesn't do the trick; replace the LCD screen.

Acer laptop switched on light up on switch but no screen display


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

I dropped my laptop, now when i switch it on, the screen is striped to the point where nothing is legible. What can i do to fix this? Is it worth it?


Posted ahead of myself. There is a flow, or method; that is used, and should be followed,

1) Laptop OFF, monitor OFF; connect a VGA monitor to the VGA port, on the Left/middle side of the laptop. {White}
(General example of a VGA Cable, and VGA connector, {Port},

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

Scroll down a little for VGA Cable example)

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

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
No display on external VGA monitor?

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

Press, and hold down on the Fn key, and at the same time tap once on the F7 key. (The F7 key is the Display Toggle-Over key)
Still no display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F7 key.

I think the display on the external VGA monitor, will be fine. Could I be wrong? Yes. If the display still has lines going through it; the graphics chipset's mounting to the motherboard, is the problem.

Most want to just replace the motherboard.
Now you're talking about bucks. $200 + for just the motherboard.

There are methods to reflow the graphics chipset's mounting, and re-seat the graphics chipset to motherboard. One professional, and a Bunch of amateur methods.
If you find this to be the problem, post back in a Comment, and we'll deal with it.

Good display on external VGA monitor, means the graphics chipset mounting is not the problem; the problem is the Video Cable, or inside the Display Assembly. (Screen Inverter/LCD screen)

The Video Cable plugs into the motherboard, under the Keyboard; in an area close to the Alt key on the left side of the Space Bar.
It then leads straight up towards the LCD screen, curves towards the left Hinge, and through the left Hinge.

From there the Video Cable leads up into the Display Assembly. Connects to the back of the LCD screen, and a small cable comes off the Video Cable to the Screen Inverter.

Laptop off, ALL power removed. (Remove the AC adapter {Charger}, and Battery)
Suggest lay a soft static free cloth on the table you're working on; and laptop turned Bottom side up, Battery Compartment facing away from you; down on the table.

You need to remove the Switch Cover, (Keyboard securing strip); above the Keyboard, and Keyboard laid over; in order to access the motherboard connector for the Video Cable.

http://www.insidemylaptop.com/take-apart-sony-vaio-vgn-fz220-repair-power-jack/

Go to Step 3. Remove the DVD drive.
Go to Step 4.
ONLY remove the screws circled in Green. They are for the Switch Cover.

Follow Steps 5 through 7. Remove the Switch Cover.
(Release those 3 Latches in Step 5, and 2 in Step 6)

Note* You want to use Finesse when removing the cover. This is not detailed here.
A stiff guitar pick, or a Spudger tool, are infinitely better than using a metal tool.

In Step 7 the tool should be gently inserted, on the Right side of the Switch Cover, at the parting line in-between the Switch Cover, and Bottom Cover. (Base Enclosure)

Once this side starts to lift up a little, use a small tool to gently pick up on the right Hinge cover. The Hinge cover is part of the Switch Cover.
Keep working along the bottom edge, and top edge of the Switch Cover, with your fingers, and pop it off.

(See the speakers in Step 8? NOT a good idea to use a metal tool, but also do Not insert the tool you are using; too far in )

Remove the two Philips head screws securing the Keyboard, at top.
Raise the Keyboard up on the screw side about 1 inch; slide the Keyboard towards the LCD screen a little.
You are trying to slide the plastic tabs at bottom of Keyboard, out of the Palm Rest Cover. (Top Cover)

Then lift the Keyboard up the screw side, roll over (Top), and lay Keyboard down on the Palm Rest Cover.
You do not need to remove it. Just access the Video Cable plug/motherboard connector.

Try to physically plug the motherboard side of the Video Cable, in tighter.
Photo in Step 10 shows gray Video Cable, and it's Black plug connector.

A) How to remove the Display Bezel, and lay LCD screen over a little, to check LCD screen side connection for Video Cable,

http://www.insidemylaptop.com/remove-lcd-screen-inverter-board-sony-vaio-vgn-sz645-display/

B) More information shown in a disassembly video,

http://www.youtube.com/watch?v=sujKznS_Mns

Pertinent information is shown;

A) 2:35 to 3:13; Switch Cover and Keyboard (Roll over, lay down on Palm Rest Cover)

B) 3:31 to 3:49; Video Cable connection, motherboard side.
That is what he is disconnecting at 3:49

C) 12:20 to 16:10;
1) Display Bezel removed you can see the screen Inverter. It is located at the bottom of the LCD screen.

Example of the screen Inverter (Board),

http://www.ebay.com/itm/Sony-Vaio-VGN-FZ340E-15-4-Laptop-Genuine-1-443-890-11-LCD-Inverter-Board-Tested-/170770015618?pt=LH_DefaultDomain_0&hash=item27c2afa582

Check screen Inverter connection.

2) Showing how to partially remove LCD screen, and check Video Cable connection to LCD screen

I do Not think you need to remove the Display Assembly; in order to remove the Display Bezel.
That is why I posted the Insidemylaptop VAIO VGN-SZ 645 info, above.

You can check the laptop, after you may made sure all Video Cable connections are tight; and not put everything back together, before you do.
This way if the Video Cable connections are Not the problem, you do not have to disassemble all over again.

Visually inspect the sheath of the Video Cable.
If there is any apparent damage to the sheath of the cable, there is also a good chance the tiny wires inside the Video Cable, are damaged.
(Stretched/Broken)

You NEED to verify the Video Cable is Not the problem, before continuing on.
Connections weren't it; no apparent visual damage; remove the Video Cable, and take it to a small computer repair shop.
There the tech can take the cable, and with a multimeter set to OHM's, check each wire in the cable for Continuity.

(Also should have an assistant gently wiggle the cable, and see if there are any intermittent readings on the multimeter. Intermittent reading indicates broken wire/s )

Video Cable checks out; connections, and continuity test; the screen Inverter is next.
Test requires a Sensitive multimeter. Read fairly expensive,

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

Since ease of access, and low cost is a factor for the screen Inverter, most just decide to replace it.
(Parts changing I know; but if you do not have access to a sensitive multimeter? Take laptop to a shop to test screen Inverter, and you'll wind up paying for a screen Inverter, AND labor)

Screen Inverter checks out, or is replaced, and still same problem?
Replace LCD screen.

For additional questions, or clarification on anything I have stated above; please post in a Comment.

Keyboard lights up screen stays black....after inserting recovery disk screen still remains black...


Would like you to attach an external monitor for a diagnoses.

A VGA monitor.
Can be a CRT monitor that resembles a small TV, or a flat LCD screen monitor, that has a VGA cable attached,

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

1) Laptop OFF, monitor OFF, attach the VGA cable of the monitor to the laptop's VGA connector.

[For the HP Pavilion dv6000z Notebook PC, the VGA connector is on the Left side at the Rear. Second port from the rear. 15 pins.
3 rows of 5]

2) Turn the monitor on. If a CRT style allow it to warm up.
3) Turn the laptop on.

By default the display should show on the external VGA monitor.

If not, press, and hold down on the FN key,
(Second key from the left, on the Bottom row on the Keyboard),
and tap on the F4 key.
(Top of Keyboard towards the left)

Still no? Hold the Fn key down again, and at the same time tap on the F4 key.

There are 3 display options;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

IF, the display shows up on the external monitor, and if it is OK, the problem lies in the Display Assembly, and/or the Video Cable.

More on that in a moment.

IF, the display does Not show up on the external monitor, or if it is garbled, the graphics chipset is bad.

HOWEVER, there is a problem with the graphics chipset, for the dv6000 series of HP Pavilion Notebook PC's.
More specifically it isn't actually the graphics chipset itself, but the mounting of the graphics chipset to the motherboard.
More on this in a moment.

External VGA monitor shows a good display;
Video Cable:
The video cable is checked for apparent damage first, and at the same time, see if it's connectors are tightly plugged in.

On one end, the video cable is plugged into the motherboard.

(ALL power removed, AC adapter { Charger} and Battery, the Switch Cover is removed, and the Keyboard, far enough to lay it back out of the way. Keyboard Cable still attached to motherboard. The Display Cable is the one to the Far left, right under the left side of the LCD screen. The cable next to it, to the immediate right, is the Microphone Cable )

The video cable routed from the connection on the motherboard, up under the left Hinge Cover, and into the Display Assembly, where it then attaches to the Back of the LCD screen.

THIS connection must be checked also.

{ Just gave advice similar to this earlier. The asker's problem turned out to be a loose video cable connection, on the back of the LCD screen }

Examine the sheath of the video cable. See if there are signs of damage. If so the tiny wires inside the cable could be damaged.
Apparent damage or not, you may want to remove the video cable, and perform a continuity check with a multimeter. (Ohm's. Check each wire in the cable)

Video Cable connections prove to be tight, video cable continuity check proves video cable is OK, move on to the screen Inverter.

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

A Backlight can be a CCFL, or a series of LED lights.

The Backlight is a CCFL for an HP Pavilion dv6000z Notebook PC.
[It is 2mm Wide, and 334mm Long. Or a little thicker than 1/16th inch Wide, and a little over 13 inches Long ]

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

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

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

Example of a screen Inverter for a Pavilion dv6000z Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&products_id=560

The thin plastic frame that surrounds the LCD screen, and is in front of the LCD screen, (Resembles a picture frame), is the Display Bezel.
The screen Inverter is located behind the Display Bezel, and at the bottom of the LCD screen area.

External VGA monitor does NOT show a good display, it is a graphics chipset mounting issue, more to follow.

Screen is blank. Computer is switched on.


This is probably due to a video card failure. It could also be a ribbon that connects to the motherboard for the LCD monitor. You can remove the keyboard and find the strip that connects the lcd screen to the motherboard. Not too much info but thats a start...

How do you switch between laptop screen to external monitors


You can switch to an external monitor by two methods.
1. Connect the external monitor to the laptop's video port, power up the external monitor first and the the laptop. The video information will automatically switch to the external monitor.
2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between external monitor only, both LCD screen plus external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :-
IBM ThinkPad = Fn + F7
HP and Compaq = Fn + F4
Toshiba = Fn + F5
Dell = Fn + F8
