Can you see the display even if there's no light? It would be very helpful for me if you let me know that. You can check this with a flashlight. Awaiting your response.

I DONT SEE ANYTHING IN MY SCREEN BUT TOTALLY DARK


If you shine a bright light at the screen and you can see something, the back light/inverter may have failed. If nothing at all, check on an external screen.

The back light is the whole of the screen, the screen is illuminated by a CCFL lamp (fluro tube) on the bottom of the screen. A inverter supplies high voltage to this CCFL lamp.
If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :-

My dell inspiron laptop 1000 screen turns dark every few seconds. if I close the computer half way and open it,it stay bright for a few seconds and turns dark again


This is your back light on your lcd display, To prove that have a flash light handy when it goes dark point the flash light at the screen and you should see the screen and that would mean right there you got a back light going out or the inverter that powers it is going bad. Etherway if this is not your area of work you need to tech it to a computer tech local to have it repaired.

Thanks for being considerate with your ratings and feedback today.

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.

Disply screen is dark


Hi

Thank you for your query

The problem you are describing is related to your inverter board

The inverter board is responsible for ramping up the power from 12v to 240V to allow the LCD screen to light up

Please can you book the laptop in at a reputable PC shop for a inverter replacement

My toshiba screen


Shine a torch light onto the screen. If you can see a faint outline of the images, it could indicate a back light failure. Unfortunately, you cannot fix this by yourself. You will need to take it for servicing.
