Laptop screen becomes black after 1 second

You have to diagnose the problem.......

Right off hand I would say the screen Inverter is bad, but this is just guessing......

Because your laptop may not use a screen Inverter.
It may use LED's as backlighting.

Or, it may have a pinched/damaged video cable.......

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)

A CCFL is a Cold Cathode Fluorescent Lamp. (Bulb)
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, or about the width of this capital letter -> O <-

Average length is almost as long, as the LCD screen is in height.

A screen Inverter is used to convert the power, (Electricity), of the laptop; for the LCD screen, and the Backlight.

A laptop that uses a CCFL, (Or more than one), uses a screen Inverter.
A laptop that uses LED backlighting, May or May Not use a screen Inverter.

Seems when the LED backlighting technology first came out, a few laptop models Did use a screen Inverter.
As the LED backlighting technology evolved, a screen Inverter was no longer used.

Average example of a screen Inverter,

The LCD screen is in the Display Assembly.
The plastic frame in front of the LCD screen, is the Display Bezel.
(Different manufacturers use different terms. The above is for HP, and Compaq laptops)

Display Bezel removed, the screen Inverter is located at the bottom of the LCD screen.
That is IF, the laptop uses a screen Inverter.
If the Backlight is bad on a laptop that uses LED backlighting, the LCD screen itself is replaced.
The LED backlighting is built-in.

The Video Cable, (Display Cable, etc), connects to the motherboard, usually under an area under the Keyboard, or just above it. Some models have the Video Cable connecting to the Bottom of the motherboard, and at the back.

Average example of a Video Cable,

The Video Cable then routes through Channels, and Latches; and comes up around the left Hinge.
It then goes on to up into the Display Assembly.

Depending on the technology used, (screen Inverter, or no), the Video Cable splits off, and connects to the screen Inverter.
The rest of the Video Cable then connects to the back, of the LCD screen.

Due to just normal opening, and closing of the laptop; the Video Cable may become pinched, and/or pulled on.

This can cause the connection at the motherboard to become loose, and/or at the screen Inverter, (IF used), and/or at the back of the LCD screen.

It may also cause damage to the Video Cable. (Stretched/Broken)


1) May be just a loose connection/s of the Video Cable
2) May be a damaged Video Cable
3) May be a bad screen Inverter
4) May be a bad LCD screen.

Post in a Comment, as to the laptop manufacturer name, and model number.

This way I can step by step you through diagnosing the problem, for YOUR laptop; and not post a bunch of generic information.

HOWEVER, it does depend on if the information is available on the internet. Such as a free Service Manual, and/or pictorial guides.

I CAN guide you even if there is not, but if there is; it just makes it simpler for you.

I can tell you it is easy. Once you have performed this procedure, you may want to do it for a friend, or relative; if the situation arises.

No backlight

A) Replacement LCD screen backlight could be bad.
Happens. Sometimes you get a bad part. (Bad LCD screen assembly, in this case)

LCD screen may not be the correct one.

A screen Inverter, and an LCD screen; are a MATCHED unit.

B) Screen Inverter:
May be bad, or the Wrong one

C) You may not have the screen Inverter, connected correctly to the Backlight.
Connections aren't tight.

D) The Display Cable TO LCD screen connection may not be tight, or correctly connected.

I know the display shows graphics, but a poor connection of Display Cable to LCD screen, can make the Backlight dim out.

I'm betting it is a poor connection, or the wrong screen Inverter, or wrong LCD screen.


(Be shame to kick that laptop to the curb. Nice laptop)

Just replaced my dell laptop e6500 lcd screen but the screen comesup white grey then turns black with no booking up on screen.

check connections to the inverter, check inverter wires not damaged ( the ones that run to the screen bottom). Check cable to screen rear is tight and then check cable to motherboard is tight.

if no luck, suspect faulty inverter, or screen cable or... if the screen was not new, incompatible or damaged screen

Power comes on but screen stays black

The backlight inverter board may be bad, or worst case will be bad lamp. You should look to see if the cable comes off the inverter board first. You may learn maore here:

This could be an inverter or backlight problem. If you are seeing the image as dim, then it could be with the inverter.

Gateway Solo 9550

If you can see a faint image of the desktop or the machine works with an external monitor, the either the screen inverter or the screen backlight has gone out. Start by checking the screen connections. The connection to the screen, screen to inverter and screen to motherboard. Connections can sometimes work loose. A loose connection generally causes the screen to go out entirely, rare but occasionally it can cause just the backlight to go. If the connections are good, then you will need to take it in to have the screen and inverter tested to find out which it is. If it turns out to be the backlight, you will have to purchase a new screen, screen are considered sealed units and just the backlight can't be changed out.

Black screen

First, plug a external monitor and toggle the screen to discard configuration or software problems. If the image displays correctly you have a problem either in the LCD screen, the inverter or its connection cable.
Open the bezel and check for loose or damaged connection cable. Look specially next to the hinge.
Try also replacing the inverter.
In case the problem is not the cable or the inverter you might have to get a new LCD. You can have replacement parts and instructions here:

Opening a Gateway Solo 2150 laptop

I found the answer on another wed site. I tried it on my Gateway Solo 1500 and it works! The extra screws are hidden on top. You carefully remove the small face plate around the power button. I used a very small screw drive to lift it off.

Opening Gateway Solo 1400
by Aelanna - 2/3/05 11:04 AM In reply to: Gateway SOLO 1400 by hunjibunji
I'm also an A+ certified tech, but I've done notebook service for a lot of years. I just finished opening up a Gateway Solo 1400 and it was NOT easy! There are no screws holding the keyboard on the bottom of the machine. You can get the case open about 95% and there will be one area stuck, in the back near where the screen cable goes into the unit. There is a hidden screw on the top of the case next to the hinge. To get to it, you have to remove the two screws that hold the plastic hinge cover and pry off the cover. I only managed to find it after removing the keyboard, the display, and the panel with the LEDs and power button. (The screws holding the keyboard are on the top of the machine, underneath the cover with the power button on it.)
