Try connecting an external monitor and see if there is a display showing on it when you start the laptop.

Try shining a torch at an angle close to the laptop screen to "see" if you can detect any display being shown once it has started.

If not and there is also no display on the external monitor then there is a problem with either the GPU (most likely it is integrated into the CPU) or the motherboard.

If there is a display on the external monitor and you can 'see' a display on the laptop then most probably you have a backlight problem. It could either be the backlight power supply, in the LCD panel itself or perhaps it may be the lid switch is either disconnected or faulty. The lid switch is usually a magnetic switch. With the switch in the lid and the magnet in the case or vise versa. This switch controls the power to the backlighting in the display panel.

Here is a link to the service manual for your laptop. Scroll to p.7 to see the location of the switch.

If there is a display on the external monitor but you cannot detect anything on the LCD screen when using a torch then the problem is either a faulty video cable between the motherboard and the screen, faulty connections on the video cable either at the motherboard end or the screen end or a faulty display panel.

Once you have determined what the problem is, if it is a faulty part, in the service manual you will find the part number for the part. Using just the number search online and you will get results for suppliers of the part.

Hopefully this is of some help.
