Solved! Need help : my laptop doesn't boot properly

[farhood_ka]

Greeting everyone
I have a MSI GE62VR laptop and when I press the power button, LED lights glow, fan spinning sound is heard, but the display remains black, and the notebook does not start but it's very very odd because sometimes my laptop boot perfectly and sometimes I have this issue.
I've checked hard drives, battery, windows, laptop monitor and all of them were fine.
could you help me? I'd appreciate your help.
Thanks

Try using an external monitor... it could be that your laptop display is broken, or there is a short connecting the screen to the body of the computer.

If an external monitor works ok, you know it is the laptop screen.

Good luck,
