Hiya guys. just a quick question im in the process of fixing my laptop the the backlight on the screen went off. i hooked it up to my pc monitor to see if it was the backlight and it was so i ordered new inverter fitted it and still on joy. so i ordered a new screen fitted that no joy so im at a bit of a loose end as what it could be???? any ideas i would be greatfull im thinking the 30 pin conecter or the motherboard

thanks in advance Andy

Do you get anything on the screen, or is it completely black? Can you see any sign of the backlight working? If the external monitor connection is working, then I'd say it's either the connection to the laptop screen, or the laptop screen itself. LCD displays work by allowing light from the backlight to pass through crystals, so maybe whatever controls that has broken.

As you say, sounds like there's a problem with the connection to the screen. Either the connector, or maybe the output on the graphics card to the laptop in screen has broken. Either way I dobut it'll be an easy fix.
