Question

When i turn on my laptop, it does not show anything. All it shows is just the white screen and nothing else. when i turn off my laptop(by pressing F4), i hear the sound that would usually come out when it is off. So, basically, i believe that the only thing that is wrong with the laptop is the screen which does not show anything, but the white screen. I would be very pleased if someone could help me with this. Thanks for reading. p.s this laptop is from LG and i have no idea where to fix this problem from. Please let me know.
