Screen not working
are you able to hear the windows log in?
if you do but no image, most likelly your video card is ruined. overheated or dropped maybe? don't worry is bad but not that bad, there is a way to fix that by a professional.
take it to a computer repair shop and have them check the video card ask if they have a rework station or someone who may. they have to unsolder about 50 pins at the same time get a new card and solder it again.
sometimes they apply heat to it and it will work again but for just a few days maybe weeks but it goes bad again. so replacement is the best option.
I used to charge about 200 bucks but you may be able to ask for a rebate.
do not take it to a major computer store they would tell you there is no repair so you can go in and get a new computer

I recommend that you do a system restore to the entire paartition on your hard drive. With ASUS notebooks, this can be done by restarting the computer and pressing F9.

Price inverter for your laptop screen. Have it professionally installed unless you know hardware, static, etc. It can be a big job with some laptops being completely dismantled to access the inverter. I've done quite a few. Some laptops have a bezel that is very difficult to open. (Like working on a dollar store toy--only it costs $1000!

If the laptop boots up all the way and you don't see an image on the lcd screen or on the external monitor then the video card inside the computer is bad.

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 the video shows on the external monitor that proves your video card is ok, ,but your lcd screen is bad. 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 bad.

Why did you replace the lcd inverter? Were you able to barely see icons on the desktop which is an indication that the lcd inverter is bad? If not, then you need to replace the lcd screen. If you could barely see the icons and you replaced the lcd inverter, then the inverter is bad. Just because the inverter is new does not mean it works. If the video shows on the external monitor, but you can't see anything on the laptop's screen even when you shine a flashlight on it then the lcd screen is bad.

I have a toshiba qosmio f25-av205, when you start it up the screen showes for about 15 seconds then goes dark, can see the screen on external monitor. Can also see it very faint on screen at same time. ...


In my experience, if a back light goes out, it doesn't work at all. Since yours works for a short time before going dark, I'd say that it's your inverter that's faulty.

Your Question My Toshiba Satellite m115 will boot up but the monitor wont light up, you can see the images in the back round but the screen is dark. if i connect to external monitor the external monitor...


Diagnosis:
1. Test using an external monitor. If it works, then either the screen bulb or the inverter board might be defective.
2. Test the inverter. Easiest way to do it if you have a good screen with a good bulb. Connect the good screen to the inverter board & test it. If it lights up, then the inverter board is good. If it did not, then the inverter board is bad & needs to be replaced.
3. If the inverter board is good, then we are left with the possibility that the screen bulb is bad. To fix this, we will need to replace the LCD screen.

My brightness control does not work just turned on and can not hardly see anything it is up and running what now


Have you tested it with an external monitor?

I would say you either have a damaged inverter board or screen baclight lamp. Usually the inverter board fails in one of the following ways:

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.
