    Have you checked your display while on battery settings?
    All laptops dim their display while on battery power.
    You may need to increase yours.
    Look under your power options.

    Good clue. Something is turning off the backlight. I've not seen that before. So I'm scratching my head.

    Adding to AllHeart's comment - which is what you should check first. If you're still having problems, pull the main battery and remove the AC power adapter. Hold the power button for 30 seconds. Install battery and connect AC power adapter. See if that helps.

    If that doesn't work, try booting in Safe Mode. If you don't know how to boot to Safe Mode, tell us what version of Windows you're running and we'll provide instructions.

    Thanks

    However

    I had a spare laptop screen with a scratch on it - connected that after removing old one

    It worked ok on battery

    So does that mean the original screen is duff ?
