  1. Hello Edna Mbogori;

    Without knowing why the screen is blank it's hard to guess at the corrective action needed.

    But some common problems and possible solutions:
    Replace a malfunctioning FL inverter which powers the CCFL backlight in the LCD screen.
    Replace a malfunctioning CCFL backlight in the LCD screen.
    Replace a damaged or non-working LCD screen.

    If the reason the screen is blank is due to a bad video chip on the motherboard - you'll need a motherboard replacement.
