Samsung np300e5c Screen not turning on

[Benito_3]

I have a samsung np300e5c, Power turns On, but monitor doesn't.
Try to connect an external monitor to the VGA output but nothing.

I google this but no answer found.

What could it be? Flex? Graphic card?
Is this a common issue?

Thanks in advance!

If you are not getting anything on an external monitor it is most likely your GPU causing the issue.
