    A friend asked me to have a look at his "new" Dell Inspiron 1545 that had a screen problem. He bought the computer real cheap from an online auction house, with a faulty screen, bought a new screen (not sure if it was genuine, but unlikely) and replaced the faulty one (which was COMPLETELY dead), and the new one doesn't work either.

    It receives power, if you hold a strong torch to the screen you can see the image on the screen, and if you plug in an external monitor, the external works fine.

    At this point, you all (and me) go A HA! That will be the LCD inverter, Open the the case to discover that there is none, and you realise it is an LED screen. Seen them before, but never struck this problem with an LED screen before. Do LED screens suffer from the same inverter problems as LCDs? Do they have an inverter built in? Is it even an LED screen, or did he buy a replacement LCD instead. Its not LCD, there are NO cables protruding from the bottom of the screen to connect to an inverter.

    Seems to be very little on LED faults on Google at the moment. Any anybody help me out with some advice on what may be wrong, or where to look for further information.

    Many thanks in advance for your help

    The display is still an LCD display; what you are referring to is the backlighting, which can either be CCFL or LED. Certainly sounds like the backlight is not getting power.

    I'd suggest having a look at this: http://support.euro.dell.com/support/edocs/systems/ins1545/en/SM/display.htm#wp1202970 to see what your notebook may be missing; could be an incompatible display possibly?

    Do you have an external display, try plugging that in, loading windows and getting the hardware ID of the laptop display from windows.
