The monitor backlight on my Toshiba Portege keeps going out.

This answer was rated:

The monitor backlight on my Toshiba Portege keeps going out. Can I fix this myself via the keyboard or is it likely to be permanently on the blink? Cheers XXXXX XXXXX

John :

Hello and Welcome to Just answer. My name is XXXXX XXXXX will be assisting you today

John :

Hello sir,is it just the back light or the screen goes completely blank?

Customer:

Hi John, yes the screen goes blank but not totally, I can see the screen images very faintly. A torch at the fron t of the screen helps.

John :

OH OK thanks for that update.so the external monitor works fine even if the laptop screen display goes half blank am i correct

Customer:

External monitor works fine. If I chose to view laptop screen, I can see images faintly but there is no backlight.

John :

Have you tried increasing the brightness of the laptop screen?

Customer:

Yes I have, this makes no difference. I should stress that the images I can see are extremely faint, dark and illegible. On a couple of occasions when I have toggled between both screens (ext monitor and laptop) and ext monitor only, the laptop monitor backlight has come on but this has extinguished itself very quickly. Now I can't get the monitor backlight to work at all, as if it has blown.

John :

OH OK it seems like the back light tube or power inverter to the laptop screen is not functioning also there is a chance that both are not functioning but most likely the back light tube that is causing this.

John :

This link shows how you can change the power inverter to the laptop screen http://www.laptoprepair101.com/laptop/2007/01/31/replace-screen-inverter-fix-backlight/
This link shows how you can change the back light tube (CCFL) http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

John :

For both you need to open the screen part of the laptop

John :

CCFL tubes can cost from 15$ to 30$ and power inverter will cost 20 to 25$

John :

If its under warranty you can replace it for free from Toshiba itself if its not under the warranty still Toshiba is the best but they will charge more than others
