Dark Shade on my monitor

[Shelob182]

Hi Everyone,
I have a Philips 227E LHA LCD monitor. Never had a problem with I until today.
I noticed a big dark shade on the top right corner (picture attached).
I dont know how it happend, the only clue I have is that my pc is close to the window so Im wondering if it might have been the sun?!.
But it never happened before.

Any ideas or solution?
Thank you!

Your backlight is broken, time for a new monitor
