More then Likely the Back light is bad its a pretty common problem with netbooks and laptops .... check the bios to verify theres not a setting also check out your keyboard keys... there is a function button (fn) that can be used with another key (not sure on your model) looks like a monitor usually ...when pressed together can switch between displays ...might be a simple fix if it got pressed at some point on accident

I can only see half of my screen


I suggest you have a bad LCD screen.

HOWEVER the procedure is to diagnose, and not spend money foolishly.

I need to know the laptop manufacturer name, and model number.
I cannot for the life of me believe FixYa would not ask for this, as a general requirement.

The model number is on the Bottom of the laptop.
Post back in a Comment.

In the meantime,

1) Check the graphics chipset first.
Connect a VGA monitor to the VGA port, on the laptop.
If the VGA monitor shows the same horizontal split of the LCD screen, then your graphics chipset is bad.

Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on 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 an example of a 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.

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 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.

Here's where it gets rough, Dawn;
Hold the Fn key down, and at the same time tap once on the Display Toggle-Over key.

What key is that? Dunno. Laptop manufacturer name, and model number wasn't stated.
HP is usually the F4 key.
Acer? F5 key
Lenovo/IBM? F10 key.

The F key at top should have a monitor outline symbol, and an arrow on one side; for the Display Toggle-Over key.
No display on external VGA monitor?
Hold the Fn key down again, and tap once more on the Display Toggle-Over key.

Same display of internal monitor on the external VGA monitor?
Bad graphics chipset. Actually it is probably the MOUNTING of the graphics chipset TO motherboard.
More on that if it is the problem.

Good display on external VGA monitor?
Problem is the Video Cable, or inside the Display Assembly.

2) Video Cable:
The Video Cable connects to the motherboard, (In an area under the Keyboard, or Switch Cover above it), runs under the left Hinge; and up into the Display Assembly.
From there it may have a small cable coming from it, that connects to the screen Inverter.
The main part of the Video Cable then connects to the back of the LCD screen.

CCFL backlighting uses a screen Inverter.
(Cold Cathode Fluorescent Lamp)
LED backlighting May, or May Not.

Due to repeated normal opening, and closing of the laptop; the Video Cable may become pinched.
This can cause pulling on the Video Cable, and loose connections.

It can also cause damage to the tiny wires inside the sheath, of the Video Cable.
(Stretched/Broken)
If you see apparent damage to the sheath of the Video Cable, suspect damage to those wires inside.

Loose connection of Video Cable TO motherboard, or TO screen Inverter, (IF used), or back of LCD screen connection.

The procedure is to remove what components are needed from the laptop, to access the motherboard connector side of the Video Cable; and PHYSICALLY check to see if it is plugged in tightly.

{Components may only be the Switch Cover.
Above Keyboard, and below LCD screen. Has the Power On button, indicator LED lights, and perhaps speakers.

May be the Switch Cover AND Keyboard.
May be the Switch Cover, Keyboard, and Palm Rest Cover; in order to access the motherboard connector of the Video Cable }

Disconnect the LCD screen from the Display Cover, to access the LCD screen side connection, of the Video Cable.

Once all connections are proved to be tight, try the laptop again without fully reassembling. See if you can connect everything, with the LCD screen sitting out a little. Perhaps the Switch Cover off, but wires connected.

HOWEVER of you see apparent damage to the sheath of the Video Cable, or if you don't; the Video Cable MUST be ruled out before going on.

Connections tight? Didn't repair the problem? Remove the Video Cable.
A continuity test of the Video Cable must be performed, with a multimeter set to OHM's.
EVERY wire in the Video Cable must be checked for continuity.

Also an assistant is needed to gently wiggle the cable in the middle, and see if you get an intermittent reading on the multimeter.
If so this indicates a broken wire inside the Video Cable.
Replace.

Not everyone has a multimeter laying around.
Suggest take the Video Cable to the nearest small computer shop, and have the resident tech check it for continuity.
Should only be a couple of bucks.
(They say they can't check it? GET OUTTA THERE!
That ain't no REAL tech! Lol!)

Video Cable checks out?
Then the next component to check is the screen Inverter, again IF used.
Problem is to check a screen Inverter requires a sensitive multimeter.
Read fairly expensive,

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

For the above reason; the ease of access to replace, (Just remove Display Bezel), and usually low cost; the screen Inverter is usually just replaced. Average cost is around $20, or less.

Screen Inverter isn't used? Problem is LCD screen.
Screen Inverter replacement didn't repair the problem?
Problem is LCD screen.

I know the above may look like, "Wah, wah, wah", from Charlie Brown. (That's what my niece tells me)

If I had the manufacturer name, and model number, I may be able to give you a link to a Service Manual, and possibly pictorial, or video guides; PLUS step by step info from me.

Makes it less, "Wah, wah, wah", lol!

Display divided into 3 parts


LCD screen cracked, and Three even strips going across? Doubtful. Haven't seen it but I always have my mind open.

Three strips that are irregularly shaped? Look like glass that has cracked?
'Jagged edges'?

LCD screen is broken.

Three even strips indicates to me, that there may be a problem with the Video Cable. Then the screen Inverter is next in the diagnoses.
My money is on the Video Cable.

ALL power removed, Anti-Static Precautions FOLLOWED, I would check out the graphics chipset first.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the laptop.
Left rear side. This is an example of a VGA Cable, and VGA connector. (VGA port on a laptop ),

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

(Color of connector does Not matter. It is generally Blue, though)

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.

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

There are at least 3 display options available;
1) Laptop internal monitor ONLY
2) Laptop internal monitor AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the same time tap once on the F5 key. (The F5 key is the Display Toggle-Over key)

No display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F5 key.

Is the display on the external VGA monitor, the same as the internal monitor of the laptop?

Problem is the graphics chipset.

Display is fine on the external VGA monitor?
Problem is the Video Cable, screen Inverter, or LCD screen.

Video Cable:

A) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-14.jpg

Switch Cover removed, Keyboard removed. Shows you where the Video Cable plugs into the motherboard.

B) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-21.jpg

Palm Rest Cover you can see the white rectangular connector, for the motherboard side of the Video Cable, at the top left.
It's above the black cable, and near the screw hole.

The Video Cable leads from the motherboard, up through the left Hinge, and into the Display Assembly.
From there it connects to the screen Inverter, and back of the LCD screen.

http://www.ebay.com/itm/Toshiba-Satellite-A105-6017B0050801-LCD-Video-Cable-Genuine-OEM-Laptop-TESTED-/290754851160?forcev4exp=true&forceRpt=true

In the photo, (You can hover your mouse cursor on it to enlarge), the right side connector plugs into the back of the LCD screen.

The black connector to the far left connects to the motherboard.
The small white connector at the top with the Red, Green, Black, etc wires, connects to the screen Inverter.

(The small Black cable, that comes out from the black motherboard connector, is a Ground wire )

Due to the close proximity of the Video Cable to the left Hinge, it can be pulled on from just normal opening, and closing of the laptop over time.

This means the Video Cable connection on the motherboard side could be loose, or the LCD screen side, or both.

The diagnoses is to PHYSICALLY check BOTH connections. A loose connection at the motherboard, or at the back of the LCD screen could be so small in distance, that you will not see it with the human eye.

Could also result in damage to the Video Cable.
View the Video Cable with the Switch Cover removed, and see if there are any obvious signs of damage to the sheath of the cable.

If there is there could be damage to the tiny wires inside the Video Cable. (Stretched/Broken)

Use a multimeter set to OHMs, to check all wires inside the Video Cable for continuity, or have a 'Mom and Pop' computer store check it for a few bucks, or replace the Video Cable.

Video cable connections are tight? Video cable continuity check checks out OK?
Screen Inverter.

The test for a screen Inverter is to use a sensitive multimeter.
Read fairly expensive.

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

Not having access to a sensitive multimeter that you can use, means just replacing the screen Inverter. Seems like 'part changing', and it is, but you have to work with what you've got.

http://www.sparepartswarehouse.com/Toshiba,Satellite,A105,Laptop,Inverters.aspx

Find THE model number for your laptop, and the correct screen Inverter. A screen Inverter, and an LCD screen are a MATCHED unit.

Screen Inverter is checked out to be OK, or replaced, and symptoms are still the same, the problem is the LCD screen.

Remember, the first part of the diagnoses was to see if the divided parts were EVEN going across, or jagged and irregularly shaped.

Jagged in shape, and not even strips going across, means cracks in the LCD screen.
Replace.

How do you fix a white screen for a dell Inspiron 1100 lap top?


White LCD screen in a Dell Inspiron 1100 Notebook PC?

1) Loose connection of the video cable TO the LCD screen, and/or loose connection of the video cable TO the motherboard.

2) Bad LCD screen

3) Bad motherboard. (More specifically a bad graphics chipset)

To start the diagnoses to find out what the problem is, you will require an external monitor.

This monitor can be a CRT monitor (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
(A CRT monitor is a VGA monitor also)

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

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

The VGA port is on the back of an Inspiron 1100 Notebook PC.
It is Blue in color.

A) Laptop OFF, monitor OFF. Connect the VGA cable of the external monitor, to the laptop's VGA connector (Port)

B) Turn the external monitor on. If a CRT style allow it warm up.
Turn the laptop on.

By default, (Factory setting), the external monitor should show the graphics of the laptop.

IF Not;
There are 3 options available,

1) Internal monitor of the laptop - ONLY
2) Internal monitor of the laptop, AND external monitor
3) External monitor - ONLY

If there is NO display on the external monitor, (Display; To include a white screen);

A) Press the Fn key, and hold it down. Now tap the F8 key. (F8,CRT/LCD)

Still no display on the external monitor? Press, and hold down on the Fn key, and tap the F8 key again.

IF, the external monitor shows a white screen, Stop.
You have a bad graphics chipset. Option is to replace the motherboard.

IF, the external monitor shows graphics just fine, diagnose further.

A) Look to see if the Video cable is plugged in tightly to the motherboard, AND connected tightly to the LCD screen.

Dell Support > Inspiron 1100 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/ins5100/en/sm/index.htm

Click on - Display
Under the heading - Display Assembly, look at the partial 'photo' under the number 8.

On the left side where it shows two Philips head screws removed, is the Video Cable. Pinkish wire wrapped around a Light Blue wire.
Look at Number 9.
The display-feed flex cable is the Video Cable.

Make sure it is plugged in tightly to the motherboard.

Now go down to Number 10.
In the exploded drawing the number 7 points to the Video Cable.
(display-feed flex cable)

Shows the Video Cable disconnected from the motherboard, and going up to the back of the LCD screen.

Scroll down to the heading - Display Panel. This shows the connection of the Video Cable to the LCD screen.

Also;
The Video Cable runs through the left Hinge Cover.
Repeated opening, and closing of the laptop, may have damaged the Video Cable.

Observe the sheath of the Video Cable. (Outside wrap)
Does it appear damaged? Pinched? Torn?
Even if it does not, I suggest performing a continuity test with a multimeter.

Multimeter's function knob is set to Ohm's. (Omega symbol)
Positive probe lead (Red) is touched to one end of a wire going through the Video Cable.
Negative probe lead (Black) is touched to the other end of the wire.

Do not be concerned at this time with the Ohmage. Concern is to see if ANY reading comes up, not how much.

Perform a continuity check on all wires in the Video Cable.
(An economical, yet decent enough multimeter for this test, can be purchased for around $5 to $12. A multitude of store carry them. An auto parts store is but one example)

Video cable checks out?
The next suspect is the LCD screen.
However, read on.

Primer:
An LCD screen does not produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

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

An Inverter (Screen Inverter) is used to convert the power (Electricity) from the laptop, for the LCD screen, and Inverter.

90 PERCENT OF THE TIME the fault is the Inverter.

Example of a screen inverter for a Dell Inspiron 1100 Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&cPath=91_95_125&products_id=547

An expensive (Read - Sensitive) multimeter can be used to check a screen inverter. Not something everyone has laying around, or access to. In this case I would suggest replacing the Inverter.

(The screen Inverter is also easily accessed, AND much cheaper in comparison, than the LCD screen. Again, 90 percent of the time the fault is the Inverter )

IF, the Inverter does not cure the problem, then the problem is the LCD screen.

Review;
Check the display with an external monitor. Display checks good, run a continuity check on the Video Cable.
Video Cable checks out OK, go to the Inverter.
Inverter does not cure the problem, the problem is the LCD screen.

BEFORE beginning to disassemble;
Remove ALL power to the laptop. Remove the AC adapter (Charger), and Battery.

Observe Anti-Static Precautions.
(I would also advise using an ESD wrist strap, and connect it's alligator clip to a good ground source.

Average cost of a decent ESD wrist strap, is around $3 to $6.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
{Electro Static Discharge)

Use a multi-compartment container for the various screws you will remove.
label each compartment for the area the screw/s come out of.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder.

SOME screws look VERY similar to other screws.
Do Not mix them up.

For additional questions, or to have me explain anything I have stated here, post in a Comment.

Flat screen is going out


Replace the VGA or HDMI (whichever you're using) Cable, and the Power Cable (one of the two can cause this problem, or even worse, fry it!)

Then,...... try connecting the monitor (with new video and power cables to another pc that you know for a fact is working correctly... the problem could be your power supply, motherboard, etc..

If that doesn't work.....Return The Monitor if you can..........cuz if the above doesnt fix your problem, ........then you'll know the monitor is bad......but don't assume that til you try my solution k!
