If the screen is totally blank it means power is cut off totall before getting to the screen. First ensure that the cable connecting the screen is intact. If it is, the problem might be resolved from the board.

My screen keep going white


To me this is a hardware problem.

Let's diagnose, and see Shunka_Reid.
Connect a VGA monitor to the laptop.

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

Number 3 - External VGA display port

General example of VGA connector (port), and VGA cable,

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

Scroll down a little for the VGA cable example.

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.
General example of a CRT type of monitor,

http://www.wisegeek.org/what-is-a-crt-monitor.htm

B) 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;
There are 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 on the F4 key once more.

Do you get a good display on the external VGA monitor?
Post back in a Comment.

Also, has the laptop ever been cleaned on the Inside, to your knowledge?

Hp pavilionn dv6700 screen goes black after a while


If you shine a flashlight on your black screen and look real hard for the icons on the desktop. If you can faintly see them that means your LCD Inverter is bad. You'll have to disassemble the LCD Screen to get to it. In the mean time you can attach another monitor (LCD Flat Screen or the Old style fat CRT) with a VGA cable to the vga port on you laptop. Once you have it connected hit the FN (Function Key) + (F1 thru F12) key that that corresponds to the external display. Hold the FN Key while you hit the Function Key that is for the external display. The key might have the words LCD/CRT on it or it might show a display symbol. That's the key you want to hit while holding down the FN key. This will cause the desktop to display on the external monitor and verify that there is no problem with your Video Card inside the laptop.

I have a toshiba satellite a355-s6935 the lcd screen was replaced as it had been smashed. Now there is no display on new screen or if I attach an external monitor. All I get is black screen, is it...


Most laptops have a "toggle" to control the video-output:
* only to the internal LCD,
* only to the external VGA port,
* to both internal and external.

Toggle to activate the external VGA port, and connect an external monitor.
If you don't get a picture, then the computer's video-adapter is the problem.

Take the laptop into a darkened room, and look at the LCD screen.
If the inverter is dead, there still should be a VERY-FAINT picture.

When I connected an external VGA monitor to my IBM thinkpad 760 C the external monitor works.. but the internal/original monitor goes black what to do?


It's supposed to do that. The internal VGA card doesn't have enough power to support both screens at higher resolutions than intended.

My screen on my laptop went black.


Theres is a lot of reason associating to a black screen. First lets just assume it the screen and not the laptop. Check to see if you still see any image in the screen, you might want to do this in a lighted area. If you do, but is very dark, then your backlit light is dead and your screen needs replacement. If you don't see anything, then use a external monitor such as a computer monitor, a Tv and connect via VGA port, or HDMI if you have one or a svideo to an external souce and see if you get picture, If you do, then your Inverter is bad, or either a loose connection wiring somewhere between your comuter base and your screen. ( Because laptop tend to open and close alot) If you don't get anything via external source through your VGA, HDMi or s-vdeo, then this is something involved with your laptop. Could be from cpu, chipset, ram, or simply the motherboard itself.

My dell xps m1530 turns on but the screen stays black. Did my screen break?


Connect it to an external monitor with a VGA connection. If the external monitor comes on, yes your screen is broke.

Black screen


You need to borrow an external monitor and connect it to the VGA connector on your PB. If the system outputs video to the external monitor, then either the backlight or its inverter has failed.

Watch out that you haven't switched off the screen by accident. One of the function key combinations toggles between the built-in screen and the VGA socket on the back or side panels to allow the use of either an external monitor or video projector. The key combination toggles three ways: 1) internal screen, 2) external VGA, or 3) both. On my Acer Travelmate 2200, the key combination is <Fn> + <F5>. Please try this first.
