Shine a flashlight on the dark screen to see if you barely
see the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can be
any kind of monitor even the old big fat crt monitors as long as it has a vga
cable to connect to your computer's vga port. If so that proves your
video card is ok. The video will show on most systems when you reboot
without you having to do anything. Some systems will require you to hit the FN
(Function key) + F1 thru F12. Hold down the FN key then hit the correct
key for displaying on the monitor (F1 thru F12). The correct key will
normally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works,
then your screen is bad. If you see no icons by shinning the flash light
and nothing shows on the external monitor, then most likely your video card is
Hello there, Do you by any chance hook your computer up to an external monitor/tv? In any case, if you are able to hook the computer up to an external monitor, you should try that. Just to see if you get a picture there.
Also, On your keyboard there is a key called "Fn" (Usally near the bottom left-side) If you hold that key down, And look for a key with a small sun shaped object. (Usally on the number key's and one for tuning up, and one for down.) Hold down "Fn" and press the "up" Brightness. ("Sun"-key)
If that does not work it is very likley that its 1 of 3 problems.
1. Your computer's screen has a broken Backlight. (Basicly a flourecent lighbaulb. You can check by turning the light down in the room and pay REALLY close attention to your screen, Since everything is still displayed on it. It is just Extremely dark.
2. A cable might have gotten disconnected between your motherboard (GFX) and your monitor. Since you will most likley void any warranty if you open up your computer i suggest you leave that to someone who is fairly familiar with what they are going to find inside. However there is a small chance that you can get a picture by adjusting the screen back and fourth a bit.
3. The actual screen is broken, or the Graphic-card. And that is not an easy fix. and requiers a well trained techie to fix (And addition hardware).
Try holding down the function button on the keyboard and tap the F key with the (O) symbol above it, Its the symbol for monitor. You may have to press them a few times. That will toggle computer from its external only monitor mode. If not then hook up an external monitor to the computers vga jack and try again. If you get the external monitor to work that way and not the built on display then the built on display will need replacing and if it does not go to working at all then its most likely a motherboard issue. If the external display does work then you can continue to use it that way until you get the screen repaired/replaced.
It sounds like the backlight is failing. You may be able to prove this by shining a light across the panel and looking very closely to see if the display is actually still there, just not being lit. If this is the case it can be the backlight or the inverter. You may be able to hook up an external monitor to it and prove that it is a problem with the lcd display and not the graphics adapter but your description is common for a failing LCD/inverter.
Please rate this solution if it has helped you.
The laptop screen may turn white because of
poor connection between the video cable and the LCD screen. What you are getting is pure lamp, meaning the inverted is good. If you want
to check the video cable connection coming from the motherboard to the LCD, you’ll have to take apart the display panel
because the connector is located on the back side of the LCD screen and the motherboard. It is not an easy task for the regular user (even experienced ones). Try using an external monitor and press FN+F7 and see if you get display on the external monitor... you can use it like that in the meantime. But you have to take it in for repair to replace the screen. I hope this helps.
Just plugging in the monitor to your VGA port on the laptop won't make it display. You have to toggle to the exteral display, or both. Usually you have to hold down your function key, and then hit the external display key. It could be F1 thru F8, depending on your laptop model. Mine is F6. If you toggle thru the modes, your CRT should display . The missing pin is no concern!
Very odd, I would hook an external monitor to the laptop and start eliminating the possible driver issue. If that doesn't work ironically I have a trashed viao laptop but the monitor is still good. Let me know-
