Check the Sleep/Hibernate Mode Timer
Your laptop computer can be programmed to go into sleep mode or hibernate on its own, if it's let unattended for a period of time. There is a timer which you can set for the sleep mode or hibernate mode, which temporarily switches off the laptop, which leads to the screen going black. It may have happened that you may have set this sleep timer to have a very short duration of a few seconds, which is causing the blank screen condition. So check out the power and sleep mode settings of your laptop and lengthen the sleep mode interval if you find that to be the source of the problem.

Look Out For Driver Problems
Every one of the hardware parts of the computer, needs a software driver for its smooth operation. If the graphic driver of your laptop has been corrupted, it may lead to problems like the screen going black randomly. If this is the source of the problem, updating the graphics driver should take care of the issue.

Check Out For FL Inverter Problems
A hardware component which controls the back lighting of the laptop is the FL inverter. If you connect your laptop with an external monitor and it's working smoothly, but your laptop screen stays blank, then you can isolate the FL inverter as the root cause of the problem. Ask your laptop manufacturer's service center team to replace the part, to solve the problem.

Look out For a Bad Data Ribbon
There is another crucial part of the machinery which relays graphic data to the screen, in the form of the data ribbon, which may cause a problem. A bad data ribbon or loose connection of the ribbon may be causing the screen blackness. Get it checked with the service center.
