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 ),

(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:


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


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.

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.

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.,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.

White screen

The white screen you are getting is it just right after turning on the computer? If yes it means that you were not able to see the Dell logo correct?

Try connecting an external monitor thru VGA. While monitor and laptop is on with white screen please do this. Hold down Fn key then press F8 at the same time. This will toggle the display from the laptop to external monitor. If laptop displays to external monitor means that laptop LCD needs to be replaced.

If you do not have an external monitor try this.
While laptop is OFF. Do this. Hold down the D key then press power button at the same time.
Check if the laptop will display colors the whole screen. If you still see white screen then LCD needs replacement.

LCD mean LCD panel or the whole screen together with LCD cable and Inverter.

Hope this helps.

I have a HP pavillion dv6 that I've had for about a year and just today while working online the screen suddenly changed colors. It's not inverted but some black colors are a solid red, some whites have...

Hi there,

ASAP (and the caps are intentional) get your laptop connected to an external monitor. If the display is fine on the "big screen", it's most likely you only have a screen inverter/lcd failure. Failing Inverters can cause the effect you're seeing as well as an LCD burn out on the way.

If the displays are identical, then your video card is about to fail.

At least you'll know, and know right away.

Best Regards,

Inverted Colors When Laptop Screen is Moved

you are absolutely right.

there are basically two connections.
  1. at the motherboard end.
  2. at the display end.

any of the connector may be malfunctioning.

i ll suggest you not to open it yourself if you dont have prior experience in it.

while it wont take much to repair its not a costly affair.

if your system is under warranty it can be repaired for free.

if you find the solution helpful plz rate me carefully.
