you need to check your all connections between your computer and cpu. if connection are ok then you need to use an other lcd or monitor to check your display. once you will do that then you need to clean your ram and motherboard.

The system control circuitry that powers up the lcd/led screen and/or the display screen itself may be defective; also the motherboard itself may need to be replaced.
