Problem with xperia s LT26i

[issam]

When I start my xperia s it works fine as long as I am using
the phone

But whenever I press the power button to close the phone(not
shut down), and re-open the screen does not show any thing and it keep glowing
as if it’s turned on without any picture, blindly I can shut down the phone.

After awhile screen start showing picture

I tried fixing it by PC companion but it’s not working

In a short word

The screen glow (turned on ) but not showing anything,
